Some observations on digital appraisal

A couple of months ago I attended a Jisc sponsored workshop at the University of Westminster on digital appraisal. There were some useful presentations and discussions on a topic that I find both interesting and challenging.

Within the workshop I made the point that my approaches to some elements of digital appraisal may differ depending on the age of the born digital material I'm looking at.

For example, I may wish to take a firm line about removing modern system generated files such as Thumbs.db files and Apple Resource Forks that come into the archives - my reasons being that this is not really the content that the donor or depositor intended to give us, rather an artifact of the computer system that they were using.

However I also stated that for an older born digital archive I am much more reluctant to weed out system files or software.

It seems easy to weed out things that you recognise and understand - as is often the case with contemporary digital archives - but for older archives our lack of understanding of what we are seeing can make appraisal decisions much harder and the temptation is to keep things until we understand better what is useful.

I was thinking of a couple of examples we have here at the Borthwick Institute.

The archive of Trevor Wishart includes files dating back to 1985. Trevor Wishart specialises in electroacoustic composition, in particular the transformation of the human voice and natural sounds through technological means. He has also been involved in developing software for electronic composition. His digital archive is a great case study for us with interesting challenges around how we might be able to preserve and provide access to it.

Of course when I look at this archive there are numerous files that can not be identified by DROID. It is not always immediately obvious which files are system files, and which are software. Certainly for the time being, there is no intention to appraise out any of the content until we understand it better.

Another good case study...and one I am actively working on right now is the archive of Marks and Gran, a comedy screenwriting duo who have been writing together since the 1970's.

The digital element of this archive was deposited on a set of 5 1/4 inch floppy disks and includes files dating back to 1984.

When I carried out a first pass at the content of this archive to establish what it contained I encountered 100+ digital examples of screenplays, cast lists and plot outlines (in WordStar 4.0 format) and about 60 other files with various file extensions (.COM, .EXE, .BAT etc) that didn't appear to be created by Marks and Gran themselves.

Software and other system files were clearly present on these disks and this was also evidenced by the disk labels.

But do we want to keep this...are we even allowed to keep it? How can we preserve it effectively if we don't know what it is? Are we allowed to provide access to this material? If not, then what is the point of keeping it at all?

Given that rescuing this archive from the 5 1/4 inch floppy disks in the first place was quite a task and the fact that the size of the digital archive was small, it didn't seem right to appraise anything out until our knowledge and understanding increased.

As I spend a bit more time working with the Marks and Gran digital archive, this decision turns out to have had direct benefits. Here are a few examples of how:


WordStar

One of the floppy disks that was recovered had the label "Copy of MASTER WORDSTAR DISK (WITH INSTALL)" and indeed this is what it appeared to contain.

Why do we have actual copies of software in archives like this one?

Users of computers in the 1980's and 1990's were often encouraged to make their own backup copies of software. I've mentioned this before in a previous blog but there is this gem of information in the online WordStar 4 manual:


There will undoubtedly be numerous copies of early software deposited with archives as a result of this practice of creating a backup disk.

Of course there was an opportunity here - I had lots of WordStar files that were hard to read and I also had a copy of WordStar!

I installed the copy of WordStar on an ancient unsupported PC that sits under my desk and was pretty pleased with myself when I got it working.



Then I had to work out how to use it...

But the manual (and Twitter) helped and it has turned out to be incredibly useful in helping to understand the files within the archive and also to check back on the significant properties of the originals while carrying out file migrations.


WC.EXE

Another file within the archive that I didn't fully understand the purpose of until recently has turned out to be another tool to help with the process of file migration.

After the imperfect file migration triggered by a Windows 10 upgrade I wanted to go back and do some checks on how well this process worked.

If I could find out the number of words and characters within the WordStar files I could then compare these with similar statistics from the migrated files and see if they matched up.

But the first hurdle was how to get this information from a WordStar file in the first place. As with many things, to my modern brain, this was not entirely intuitive!

However, reading the manual revealed that there is an additional word counting utility called WC.EXE that wraps with WordStar.

Word counting advice from the WordStar 4.0 manual


Wouldn't it be great if I could find a copy of this utility!

As luck would have it, there was a copy in the digital archive!

I copied it across (on a high tech 3.5 inch floppy disk) to the old PC and got it working very quickly.

And it does what it says it will - here is the result for a file called REDHEAD.WS4


Using WC.EXE to count words and characters in WordStar


I then checked these stats against the stats for the migrated copy of REDHEAD.WS4 in Word 2016 and naively hoped they would match up.


Word counts for the same file in Word 2016

As you can see, the results were alarmingly different! (and note that unticking the box for textboxes, footnotes and endnotes doesn't help).

Twitter is a great help!

Furthermore it was suggested by Andy Jackson on Twitter that WordStar may be also counting formatting information at the start of a file, though I'm still unclear as to how this would add approximately 1,300 words. It is apparent that word and character counts are not to be trusted!

So back to equally imperfect manual methods and visual inspection...having spend some time with these files I am fairly confident that the content of the documents has been captured adequately.

Although WC.EXE didn't turn out to be such a useful file for assessing my migrations, if I hadn't had a copy of it I could have wasted a lot of time looking for it!


Print test pages

Another file within the Marks and Gran digital archive that would not necessarily be considered to be archival is PRINT.BAK. This WordStar file (illustrated below) doesn't look like something that was created by Marks and Gran.

However, the file has turned out to be hugely useful to me as I try to understand and migrate the WordStar files. It describes (and most importantly demonstrates) some of the ways that you can format text within WordStar and (in theory) shows how they will appear when printed.

This would have been quite important information for users of a word processor that is not WYSIWYG!

A migrated version of a file called PRINT.BAK, present on the MASTER WORDSTAR DISK

From my perspective, the great thing about this file is that by putting it through the same migration methodology as the other WordStar files within the archive, I can make an assessment of how successful the migration has been at capturing all the different types of formatting.


Here is how the print test page looks in WordStar - it shows the mark up used to display different formatting.

I thought my migrated version of the print test page looked pretty good until I opened up the original in WordStar and noted all the additional commands that have not been captured as part of the migration process.
  • See for example the .he command at the top of the page which specifies that the document should be printed with a header. Two lines of header text defined and Page # for page number. 
  • Note also the ^D mark up that wraps the text 'WordStar' - this tells the printer to double strike the text - effectively creating a light bold face as the printer prints the characters twice. 
  • The print test page includes an example of the strikeout command which should look like this.
  • It also includes examples of variable pitch which should be visible as a change in character width (font size).


Backup files

I described in a previous blog how WordStar automatically creates backup files each time a file is saved and I asked the question 'should we keep them?'

At this point in time I'm very glad that we have kept them.

The backup fileshave been useful as a point of comparison when encountering what appears to be some localised corruption on one particular floppy disk.

A fragment of one of the corrupt files in WordStar. The text no longer makes sense at a particular point in the document.

Looking at the backup file of the document illustrated above I can see a similar, but not identical, issue. It happens in roughly the same location in the document but some of the missing words can be recovered, providing opportunities to repair or retrieve more information from the archive because of the presence of these contemporary backups.


To conclude

When I first encountered the Marks and Gran digital archive I was not convinced about the archival value of some of the files.

Specifically I was not convinced that we should be keeping things like system files and software or automatically generated backup files unless they were created with deliberate intent by Marks and Gran themselves.

However, as I have worked with the archive more and come to understand the files and how they were created, I have found some of these system files to be incredibly useful in moving forward my understanding of the WordStar files as a whole.

I'm not suggesting we should keep everything but I am suggesting that we should be cautious about getting rid of things that we don't fully understand...they may be useful one day.

The UK Archivematica group goes to Scotland



Yesterday the UK Archivematica group met in Scotland for the first time. The meeting was hosted by the University of Edinburgh and as always it was great to be able to chat informally to other Archivematica users in the UK and find out what everyone is up to.


The first thing to note was that since this group of Archivematica ‘explorers’ first met in 2015 real and tangible progress seems to have been made. This was encouraging to see. This is particularly the case at the University of Edinburgh. Kirsty Lee talked us through their Archivematica implementation (now in production) and the steps they are taking to ingest digital content.


One of the most interesting bits of her presentation was a discussion about appraisal of digital material and how to manage this at scale using the available tools. When using Archivematica (or other digital preservation systems) it is necessary to carry out appraisal at an early stage before an Archival Information Package (AIP) is created and stored. It is very difficult (perhaps impossible) to unpick specific files from an AIP at a later date.


Kirsty described how one of her test collections has been reduced from 5.9GB to 753MB using a combination of traditional and technical appraisal techniques. 

Appraisal is something that is mentioned frequently in digital preservation discussions. There was a group talking about just this a couple of weeks ago at the recent DPC unconference ‘Connecting the Bits’. 

As ever it was really valuable to hear how someone is moving forward with this in a practical way. 

It will be interesting to find out how these techniques can be applied at scale of some of the larger collections Kirsty intends to work with.


Kirsty recommended an article by Victoria Sloyan, Born-digital archives at the Wellcome Library: appraisal and sensitivity review of two hard drives which was helpful to her and her colleagues when formulating their approach to this thorny problem.


She also referenced the work that the Bentley Historical Library at University of Michigan have carried out with Archivematica and we watched a video showing how they have integrated Archivematica with DSpace. This approach has influenced Edinburgh’s internal discussions about workflow.


Kirsty concluded with something that rings very true for me (in fact I think I said it myself the two presentations I gave last week!). Striving for perfection isn’t helpful, the main thing is just to get started and learn as you go along.


Rachel McGregor from the University of Lancaster gave an entertaining presentation about the UK Archivematica Camp that was held in York in April, covering topics as wide ranging as the weather, the food and finally feeling the love for PREMIS!


I gave a talk on work at York to move Archivematica and our Research Data York application towards production. I had given similar talks last week at the Jisc Research Data Network event and a DPC briefing day but I took a slightly different focus this time. I wanted to drill in a bit more detail into our workflow, the processing configuration within Archivematica and some problems I was grappling with. 

It was really helpful to get some feedback and solutions from the group on an error message I’d encountered whilst preparing my slides the previous day and to have a broader discussion on the limitations of web forms for data upload. This is what is so good about presenting within a small group setting like this as it allows for informality and genuinely productive discussion. As a result of this I over ran and made people wait for their lunch (very bad form I know!)


After lunch John Kaye updated the group on the Jisc Research Data Shared Service. This is becoming a regular feature of our meetings! There are many members of the UK Archivematica group who are not involved in the Jisc Shared Service so it is really useful to be able to keep them in the loop. 

It is clear that there will be a substantial amount of development work within Archivematica as a result of its inclusion in the Shared Service and features will be made available to all users (not just those who engage directly with Jisc). One example of this is containerisation which will allow Archivematica to be more quickly and easily installed. This is going to make life easier for everyone!


Sean Rippington from the University of St Andrews gave an interesting perspective on some of the comparison work he has been doing of Preservica and Archivematica. 

Both of these digital preservation systems are on offer through the Jisc Shared Service and as a pilot institution St Andrews has decided to test them side by side. Although he hasn’t yet got his hands on both, he was still able to offer some really useful insights on the solutions based on observations he has made so far. 

First he listed a number of similarities - for example alignment with the OAIS Reference Model, the migration-based approach, the use of microservices and many of the tools and standards that they are built on.


He also listed a lot of differences - some are obvious, for example one system is commercial and the other open source. This leads to slightly different models for support and development. He mentioned some of the additional functionality that Preservica has, for example the ability to handle emails and web archives and the inclusion of an access front end. 

He also touched on reporting. Preservica does this out of the box whereas with Archivematica you will need to use a third party reporting system. He talked a bit about the communities that have adopted each solution and concluded that Preservica seems to have a broader user base (in terms of the types of institution that use it). The engaged, active and honest user community for Archivematica was highlighted as a specific selling point and the work of the Filling the Digital Preservation Gap project (thanks!).


Sean intends to do some more detailed comparison work once he has access to both systems and we hope he will report back to a future meeting.


Next up we had a collaborative session called ‘Room 101’ (even though our meeting had been moved to room 109). Considering we were encouraged to grumble about our pet hates this session came out with some useful nuggets:


  • Check your migrated files. Don’t assume everything is always OK.
  • Don’t assume that just because Archivematica is installed all your digital preservation problems are solved.
  • Just because a feature exists within Archivematica it doesn’t mean you have to use it - it may not suit your workflow
  • There is no single ‘right’ way to set up Archivematica and integrate with other systems - we need to talk more about workflows and share experiences!


After coffee break we were joined (remotely) by several representatives from the OSSArcFlow project from Educopia and the University of North Carolina. This project is very new but it was great that they were able to share with us some information about what they intend to achieve over the course of the two year project. 

They are looking specifically at preservation workflows using open source tools (specifically Archivematica, BitCurator and ArchivesSpace) and they are working with 12 partner institutions who will all be using at least two of these tools. The project will not only provide training and technical support, but will fully document the workflows put in place at each institution. This information will be shared with the wider community. 

This is going to be really helpful for those of us who are adopting open source preservation tools, helping to answer some of those niggling questions such as how to fill the gaps and what happens when there are overlaps in the functionality of two tools.


We registered our interest in continuing to be kept in the loop about this project and we hope to hear more at a future meeting.

The day finished with a brief update from Sara Allain from Artifactual Systems. She talked about some of the new things that are coming in version 1.6.1 and 1.7 of Archivematica.

Before leaving Edinburgh it was a pleasure to be able to join the University at an event celebrating their progress in digital preservation. Celebrations such as this are pretty few and far between - perhaps because digital preservation is a task that doesn’t have an obvious end point. It was really refreshing to see an institution publicly celebrating the considerable achievements made so far. Congratulations to the University of Edinburgh!

Archivematica Camp York: Some thoughts from the lake

Well, that was a busy week!

Yesterday was the last day of Archivematica Camp York - an event organised by Artefactual Systems and hosted here at the University of York. The camp's intention was to provide a space for anyone interested in or currently using Archivematica to come together, learn about the platform from other users, and share their experiences. I think it succeeded in this, bringing together 30+ 'campers' from across the UK, Europe and as far afield as Brazil for three days of sessions covering different aspects of Archivematica.

Our pod on the lake (definitely a lake - not a pond!)
My main goal at camp was to ensure everyone found their way to the rooms (including the lakeside pod) and that we were suitably fuelled with coffee, popcorn and cake. Alongside these vital tasks I also managed to partake in the sessions, have a play with the new version of Archivematica (1.6) and learn a lot in the process.

I can't possibly capture everything in this brief blog post so if you want to know more, have a look back at all the #AMCampYork tweets.

What I've focused on below are some of the recurring themes that came up over the three days.

Workflows

Archivematica is just one part of a bigger picture for institutions that are carrying out digital preservation, so it is always very helpful to see how others are implementing it and what systems they will be integrating with. A session on workflows in which participants were invited to talk about their own implementations was really interesting. 

Other sessions  also helped highlight the variety of different configurations and workflows that are possible using Archivematica. I hadn't quite realised there were so many different ways you could carry out a transfer! 

In a session on specialised workflows, Sara Allain talked us through the different options. One workflow I hadn't been aware of before was the ability to include checksums as part of your transfer. This sounds like something I need to take advantage of when I get Archivematica into production for the Borthwick. 

Justin talking about Automation Tools
A session on Automation Tools with Justin Simpson highlighted other possibilities - using Archivematica in a more automated fashion. 

We already have some experience of using Automation Tools at York as part of the work we carried out during phase 3 of Filling the Digital Preservation Gap, however I was struck by how many different ways these can be applied. Hearing examples from other institutions and for a variety of different use cases was really helpful.


Appraisal

The camp included a chance to play with Archivematica version 1.6 (which was only released a couple of weeks ago) as well as an introduction to the new Appraisal and Arrangement tab.

A session in progress at Archivematica Camp York
I'd been following this project with interest so it was great to be able to finally test out the new features (including the rather pleasing pie charts showing what file formats you have in your transfer). It was clear that there were a few improvements that could be made to the tab to make it more intuitive to use and to deal with things such as the ability to edit or delete tags, but it is certainly an interesting feature and one that I would like to explore more using some real data from our digital archive.

Throughout camp there was a fair bit of discussion around digital appraisal and at what point in your workflow this would be carried out. This was of particular interest to me being a topic I had recently raised with colleagues back at base.

The Bentley Historical Library who funded the work to create the new tab within Archivematica are clearly keen to get their digital archives into Archivematica as soon as possible and then carry out the work there after transfer. The addition of this new tab now makes this workflow possible.

Kirsty Lee from the University of Edinburgh described her own pre-ingest methodology and the tools she uses to help her appraise material before transfer to Archivematica. She talked about some tools (such as TreeSize Pro) that I'm really keen to follow up on.

At the moment I'm undecided about exactly where and how this appraisal work will be carried out at York, and in particular how this will work for hybrid collections so as always it is interesting to hear from others about what works for them.


Metadata and reporting

Evelyn admitting she loves PREMIS and METS
Evelyn McLellan from Artefactual led a 'Metadata Deep Dive' on day 2 and despite the title, this was actually a pretty interesting session!

We got into the details of METS and PREMIS and how they are implemented within Archivematica. Although I generally try not to look too closely at METS and PREMIS it was good to have them demystified. On the first day through a series of exercises we had been encouraged to look at a METS file created by Archivematica ourselves and try and pick out some information from it so these sessions in combination were really useful.

Across various sessions of the camp there was also a running discussion around reporting. Given that Archivematica stores such a detailed range of metadata in the METS file, how do we actually make use of this? Being able to report on how many AIPs have been created, how many files and what size is useful. These are statistics that I currently collect (manually) on a quarterly basis and share with colleagues. Once Archivematica is in place at York, digging further into those rich METS files to find out which file formats are in the digital archive would be really helpful for preservation planning (among other things). There was discussion about whether reporting should be a feature of Archivematica or a job that should be done outside Archivematica.

In relation to the later option - I described in one session how some of our phase 2 work of Filling the Digital Preservation Gap was designed to help expose metadata from Archivematica to a third party reporting system. The Jisc Research Data Shared Service was also mentioned in this context as reporting outside of Archivematica will need to be addressed as part of this project.

Community

As with most open source software, community is important. This was touched on throughout the camp and was the focus of the last session on the last day.

There was a discussion about the role of Artefactual Systems and the role of Archivematica users. Obviously we are all encouraged to engage and help sustain the project in whatever way we are able. This could be by sharing successes and failures (I was pleased that my blog got a mention here!), submitting code and bug reports, sponsoring new features (perhaps something listed on the development roadmap) or helping others by responding to queries on the mailing list. It doesn't matter - just get involved!

I was also able to highlight the UK Archivematica group and talk about what we do and what we get out of it. As well as encouraging new members to the group, there was also discussion about the potential for forming other regional groups like this in other countries.

Some of the Archivematica community - class of Archivematica Camp York 2017

...and finally

Another real success for us at York was having the opportunity to get technical staff at York working with Artefactual to resolve some problems we had with getting our first Archivematica implementation into production. Real progress was made and I'm hoping we can finally start using Archivematica for real at the end of next month.

So, that was Archivematica Camp!

A big thanks to all who came to York and to Artefactual for organising the programme. As promised, the sun shined and there were ducks on the lake - what more could you ask for?

Some highlights from iPRES 2016

A lovely view of the mountains from Bern
Last week I was at iPRES 2016 - the 13th International Conference on Digital Preservation and one of the highlights of the digital preservation year.

This year the conference was held in the Swiss town of Bern. A great place to be based for the week  - fantastic public transport, some lovely little restaurants and cellar bars, miles of shopping arcades, bizarre statues and non-stop sunshine!

There was so much content over the course of the 4 days that it is impossible to cover it all in one blog post. Instead I offer up a selection of highlights and takeaway thoughts.

Jeremy York from the University of Michigan gave an excellent paper about ‘The Stewardship Gap’. An interesting project with the aim of understanding the gap between valuable digital data and long term curation.  Jeremy reported on the results of a series of interviews with researchers at his institution where they were asked about the value of the data they created and their plans for longer term curation. A theme throughout the paper was around data value and how we assess this. Most researchers interviewed felt that their data did have long term value (and were able to articulate the reasons why). Most of the respondents expressed an intention to preserve the data for the longer term but did not have any concrete plans as to how they would achieve this. It was not yet clear to the project whether an intention to preserve actually leads to deposit with a repository or not. Work on this project is ongoing and I’ll look forward to finding out more when it is available.

Bern at night
As always there was an array of excellent posters. There were two in particular that caught my eye this year.

Firstly a poster from the University of Illinois at Urbana-Champaign entitled Should We Keep Everything Forever?: Determining Long-Term Value of Research Data.

The poster discussed an issue that we have also been grappling with recently as part of Filling the Digital Preservation Gap, that of the value of research data. It proposed an approach to assessing the value of content within the Illinois Data Bank using automated methods and measurable criteria. Recognising that a human eye is also important in assessing value, it would highlight those datasets that appear to have a low value which can then be assessed in a more manual fashion. This pragmatic two-stage approach will ensure that data thought to be of low value can be discarded after 5 years but that time intensive manual checking of datasets is kept to a minimum. This is a useful model that I would like to hear more about once they get it fully established. There was a lot of buzz around this poster and I wasn’t surprised to see it shortlisted for the best poster award.

Another excellent poster (and worthy winner of the best poster award) was To Act or Not to Act - Handling File Format Identification Issues in Practice. This poster from ETH Zurich described how the institution handles file identification and validation errors within their digital archive and showed some worked examples of the types of problems they encountered. This kind of practical sharing of the nuts and bolts of digital preservation is really good to see, and very much in line with the recommendations we are making as part of Filling the Digital Preservation Gap. As well as finding internal solutions to these problems I hope that ETH Zurich are also passing feedback to the tool providers to ensure that the tools work more effectively and efficiently for other users. It is this feedback loop that is so important in helping the discipline as a whole progress.

OAIS panel session in full swing
A panel session on Monday afternoon entitled ‘OAIS for us all’ was also a highlight. I was of course already aware that the OAIS standard is currently under review and that DPC members and other digital preservation practitioners are invited and encouraged to contribute to the discussion. Despite best intentions and an obvious interest in the standard I had not yet managed to engage with the review. This workshop was therefore a valuable opportunity to get up to speed with the process (as far as the panel understood it!) and the community feedback so far.

It was really useful to hear about the discussions about OAIS that have been held internationally and of course interesting to note the common themes recurring throughout – for example around the desire for a pre-ingest step within the model, the need to firm up the reference model to accommodate changes to AIPs that may occur through re-ingest, and around the need for openness with regard to audit and certification standards.

This session was a great example of an international collaboration to help shape the standards that we rely so much on. I do hope that the feedback from our community is given full consideration in the revised OAIS Reference Model.

Me and Steve presenting our paper
(image from @shirapeltzman)
On Tuesday morning I gave a paper with Steve Mackey from Arkivum in the Research Data Preservation session (and I was really pleased that there was a whole session devoted to this topic). I presented on our work to link repositories to Archivematica, through the Filling the Digital Preservation Gap project, and focused in particular on the long tail of research data file formats and the need to address this as a community. It was great to be able to talk to such a packed room and this led to some really useful discussions over the lunch break and at the conference dinner that evening.

One of the most interesting sessions of the conference for me was one that was devoted to ingest tools and methods. At a conference such as this, I'm always drawn to the sessions that focus on practical tools and first hand experiences of doing things rather than the more theoretical strands so this one was an obvious choice for me. First we had Bruno Ferreira from KEEP SOLUTIONS talking about the Database Preservation Toolkit (more about this toolkit later). Then "Exploring Friedrich Kittler's Digital Legacy on Different Levels: Tools to Equip the Future Archivist" by Jurgen Enge and Heinz Werner Kramski from the University of Art and Design in Basel.

It was fascinating to see how they have handled the preservation of a large, diverse and complex digital legacy and overcome some of the challenges and hurdles that this has thrown at them. The speakers also made the point that the hardware itself is important evidence in its physical form, showing for instance how regularly Friedrich Kittler clearly used the reset button on his PC!

Conference delegates relaxing on the terrace
Two further presentations focused on the preservation of e-mail - something that I have little experience of but I am sure I will need to work on in the future. Claus Jensen from the Royal Library in Denmark presented a solution for acquisition of email. This seemed a very pragmatic approach and the team had clearly thought through their requirements well and learned from their initial prototype before moving to a second iteration. I'm keen to follow up on this and read the paper in more detail.

Brent West from the University of Illinois followed on with another interesting presentation on Processing Capstone Email using Predictive Coding. This talk focused on the problems of making appraisal decisions and sensitivity assessments for email and how a technology assisted review could help, enabling the software to learn from human decisions that are made and allowing human effort to be reduced and targeted. Again, I felt that this sort of work could be really useful to me in the future if I am faced with the task of e-mail preservation at scale.

A very expensive gin and tonic!
The BitCurator Mixer on the Tuesday night provided a good opportunity to talk to other users of BitCurator. I confess to not actually being a user just yet but having now got my new ingest PC on my desk, it is only a matter of time before I get this installed and start playing and testing. Good to talk to some experienced users and pick up some tips regarding how to install it and where to find example workflows. What sticks most in my mind though is the price of the gin and tonic at the bar we were in!

On Wednesday afternoon I took part in a workshop called OSS4PRES 2.0: Building Bridges and Filling Gaps – essentially a follow on from a workshop called Using Open-Source Tools to Fulfill Digital Preservation Requirements that I blogged about from iPRES last year. This was one of those workshops where we were actually expected to work (always a bit of a shock after lunch!) and the participants split into groups to address 3 different areas. One group was looking at gaps in the open source digital preservation tool set that we should be looking to fill (either by enhancing existing tools or with the development of new tools). Another group was working on drawing up a set of guidelines for providers of open source tools. The group I was in was thinking about the creation of a community space for sharing digital preservation workflows. This is something that I think could turn into a really valuable resource for practitioners who want to see how others have implemented tools. All the groups came out with lots of ideas and an action plan by the end of the afternoon and work in these areas is scheduled to continue outside of the workshop. Great to see a workshop that is more than just a talking shop but that will lead to some more concrete results.

My laptop working hard at the Database
Preservation workshop
On Thursday morning I attended another really useful hands on workshop called Relational Database Preservation Standards and Tools. Participants were encouraged to try out the SIARD Suite and Database Preservation Toolkit on their own laptops. The value and outcomes of this workshop were clear and it really gave a sense of how we might use these tools to create preservation versions of data from relational databases. Designed to work with a number of widely used relational database systems the tools allow data to be extracted into the SIARD 2 format. This format is essentially a zip file containing the relevant information in XML. It goes one better than the csv format (the means by which I have preserved databases in the past) as it contains both information about the structure of the data as well as the content itself and allows you to add metadata about how the data was extracted. It looks to be particularly useful for taking snapshots of live and active databases for preservation on a regular cycle. I could definitely see myself using these tools in the future.

iPRES2016 and Swisse Toy 2016 meet outside the venue
There was some useful discussion at the end of the session about how these tools would actually fit into a wider preservation workflow and whether they could be incorporated into digital preservation sytems (for example Archivematica) and configured as an automatic migration path for Microsoft Access databases. The answer was yes, but subsequent discussion suggested that this may not be the best way to approach this. The tool creators suggest that full automation may not be the best approach. A human eye is typically required to establish which bits of the database should be preserved and retained and to tailor the creation of the SIARD 2 file accordingly.
