One record in lots of data formats

For a Dev8d session I did with Owen Stephens in February I presented data for a single book and followed how it had changed as standards changed, trying above to explain to non-cataloguers why catalogue records look and work the way they do. At least one person found it useful. I am now drafting an internal session at work on the future of cataloguing and am planning to take a similar approach to briefly explain how we got to AARC2 and MARC21, and where we are heading. I took the example I used at Dev8d and hand-crafted some RDA examples, obtained a raw .mrc MARC21 file, and used the RDF from Worldcat to come up with a linked data example.

I have tried to avoid notes on the examples themselves. However, do note the following: the examples only generally use the same simple set of data elements, basically the bits you might find on a basic catalogue card: no subjects, few notes, etc.; the book is quite old so there is no ISBN anyway. The original index card is from our digitised card catalogue. The linked data example was compiled by copying the RDFa from the Worldcat page for the book; this was then put into this RDFa viewer (suggested by Manu Sporny) to extract the raw RDF/Turtle; I manually hacked this further to replace full URIs with prefixes as much as possible in an attempt to make it more readable (I suspect this is where some errors may have crept in). The example itself is of course a conversion from an AARC2/MARC21 record. C.M. Berners-Lee is Tim’s dad.

Feel free to use this and to point out mistakes. I would particularly welcome anyone spotting anything amiss in the RDA and linked data, where I am sure I have mangled the punctuation in both.

3 comments to One record in lots of data formats

  • Diane Hillmann

    This is really useful and interesting, but I’m wondering why you chose to ignore the RDA Vocabularies (http://rdvocab.info)? Given that they are optimized for RDF, and provide a much easier way to show roles of people and organizations, it seems odd to me.

  • Diane: Thank you. I ignored it for the RDA example as I followed the format of the RDA Toolkit examples and wanted it to be as independent from any implementation as possible.

    For the linked data example, which I think is what you meant, I wanted something both real world and easy: Worldcat was one place I found that record living in the wild so I didn’t have to do any hand coding. I like the Worldcat example too because you can see what it looks like in a traditional setting right next to the directly equivalent linked data. I think it’s more convincing for demonstration purposes to have something real. Also, of the actual linked data implementations I’ve had the chance to look at in any depth (Cambridge, BNB, and Worldcat), RDA has been largely absent and ignored to be honest.

    There are several potential examples also missing. I might add some of them if I get the chance and I think they will be useful:
    - AARC2 in UKMARC
    - RDA on a catalogue card
    - RDA using the BNB model
    - RDA using the CUL COMET model
    - RDA using the RDA Vocabularies
    They would all need hand-coding.

    Thanks for your explanation, I do understand the reasoning. On the other hand, it’s intensely frustrating to me that it’s so difficult to get beyond the ‘real and easy’ stuff to some examples that might really give folks a better understanding of what can be accomplished when we get beyond AACR2 and MARC. And I do know that RDA has been largely absent in the early linked data implementations–some of that is for the reasons you cite, but there may well be other reasons (wish I knew for sure). BTW, we have a proposal in to ALA Publishing to add some examples that use a more ‘native’ RDA approach …
