New year – old challenges!
February 2, 2012 About my museum job, Blogs, LAARC No CommentsSince my last post back in December a lot has happened in the world of digital preservation at LAARC (London Archaeological Archive and Research Centre). We have taken in several large archive deposits, including a great deal of digital images relating to a number of Olympic development sites, and I’m currently busily processing the deposits in order to make them accessible through our online catalogue.
We’ve also had a number of enquiries regarding our collections, ranging from a request for information on fish bone samples from archaeological sites, to questions about plans and standing building drawings of a church in the City of London which we hold in our collection. While these are standard enquiries for a collection like LAARC, they do sometimes involve the investigation of our legacy data to find out exactly what information is available.
So, what exactly is legacy data I hear you ask? Well, in the context of digital preservation it is often used to refer to files or data stored in old or potentially obsolete formats, which as a result can be difficult to access and even harder to interpret. As a result, and in particular when dealing with enquiries relating to archaeological excavations which occurred in the 1980’s and early 1990’s (when digital records were being created, but the idea of digital preservation hadn’t really entered our consciousness), it is sometimes necessary to conduct searches across this legacy data, extrapolate the required information, and manipulate and migrate the data into a more accessible format, while ensuring that the data itself has not been altered in the process.
Our standards and guidance for deposition, and our work with current depositors of archaeological records, aims to ensure that we are not faced with these problems for current and future digital deposits. However, for digital records that were created before such standards were in place, we simply have to deal with the data in whatever form we have it, and work to the best of our abilities to extract the required information. Our long term goal is to process and migrate all of the legacy data we currently hold into accessible formats which we can then provide access to online, but with legacy data from over 670 sites, it will take some time!!
I was lucky enough to get an opportunity to talk about some of these issues when I was invited to give a short presentation at the Digital Preservation: What I Wish I Knew Before I Started event, organised and co-hosted by the Digital Preservation Coalition (DPC) and the Archives and Records Association (ARA) back in January. The event aimed to give ideas and practical advice concerning digital preservation to current archive and records management students, and hopefully inspire them to get involved in this particular area. For anyone interested, all the presentations from the day are available at the DPC event page and comments from the day can be found on Twitter by searching the hashtag #dpc_wiwik.
Finally, I can’t write a blog about my work at LAARC without mentioning that it’s our 10th anniversary this year – and we are running a number of events and hands on activities both at LAARC and the Museum of London to celebrate. I had my first experience of these when I participated in the Archaeology Up Close day on the 20th January, when we put on a display of finds and records on the theme of ‘Made in London’. Various finds were on show which provided evidence for shoe making in the Roman period, medieval glass and ceramic making, and post medieval clay tobacco pipe manufacturing. It was great to be able to share our collections, and passion for archaeology, with visitors to the museum, and for my part it was certainly nice to get away from my computer for a day! Various LAARC staff will be at the Museum every Monday, Tuesday and Friday for the next 8 weeks, talking about our archive collections and archaeology in general, so come and say hello when you are on your next visit, and follow the LAARC VIP blog for more info.
