Cracking open metadata and cataloguing research with Resource Description & Access (RDA)

I have been taking the opportunity to catch up with some recently published literature over the past couple of weeks. While perusing the latest issue of the Bulletin of the American Society for Information Science and Technology (the magazine which complements JASIST), I read an interesting article by Shawne D. Miksa (associate professor at the College of Information, University of North Texas). Miksa's principal research interests reside in metadata, cataloguing and indexing. She has been active in disseminating about Resource Description & Access (RDA) and has a book in the pipeline designed to demystify it.

RDA has been in development for several years now, is the successor to AACR2 and provides rules and guidance on the cataloguing of information entities. I use the phrase 'information entities' since RDA departs significantly from AACR2. The foundations of AACR2 were created prior to the advent of the Web and this remains problematic given the digital and new media information environment in which we now exist. Of course, more recent editions of AACR2 have attempted to better accommodate these developments, but fire fighting was always order of the day. The now re-named Joint Steering Committee for the Development of RDA has known for quite some time that an entirely new approach was required – and a few years ago radical changes to AACR2 were announced. As my ex-colleague Gordon Dunsire describes in a recent D-Lib Magazine article:

"RDA: Resource Description and Access is in development as a new standard for resource description and access designed for the digital world. It is being built on the foundation established for the Anglo-American Cataloguing Rules (AACR). Although it is being developed for use primarily in libraries, it aims to attain an effective level of alignment with the metadata standards used in related communities such as archives, museums and publishers, and to provide a better fit with emerging database technologies."

The ins and outs of RDA is a bit much for this blog; suffice to say that RDA is ultimately designed to improve the resource discovery potential of digital libraries and other retrieval systems by utilising the FRBR conceptual entity-relationship model (see this entity-relationship diagram at the FRBR blog). FRBR provides a holistic approach to users' retrieval requirements by establishing the relationships between information entities and allowing users to traverse the hierarchical relationships therein. I am an advocate of FRBR and appreciate its retrieval potential. Indeed, I often direct postgraduate students to Fiction Finder, an OCLC Research prototype which demonstrates the FRBR Work-Set Algorithm.

Reading Miksa's article was interesting for two reasons. Firstly, RDA has fallen off of my radar recently. I used to be kept abreast of RDA development through the activities of my colleague Gordon, who also disseminates widely on RDA and feeds into the JSC's work. Miksa's article – which announces the official release of RDA in second half of 2009 – was almost like being in a time machine! RDA is here already! Wow! It only seems like last week when JSC started work on RDA (...but it was actually over 5 years ago…).

The development of RDA has been extremely controversial, and Miksa alludes to this in her article – metadata gurus clashing with traditional cataloguers clashing with LIS revolutionaries. It has been pretty ugly at times. But secondly – and perhaps more importantly – Miksa's article is a brilliant call to arms for more metadata research. Not only that, she notes areas where extensive research will be mandatory to bring truly FRBR-ised digital libraries to fruition. This includes consideration of how this impacts upon LIS education.

A new dawn? I think so… Can the non-believers grumble about that? Between the type of developments noted earlier and RDA, the future of information organisation is alive and kicking.
