- develop a formal RDA Element vocabulary (probably following the DC Abstract Model)
- develop an application profile of RDA for Dublin Core using FRBR and FRAD
- use RDF and SKOS to disclose RDA vocabularies (see Diane Hillmann's work on this)
- the library community gets a metadata standard that is compatible with the Web Architecture and that is fully interoperable with other Semantic Web initiatives
- the DCMI community gets a libraries application profile firmly based on the DCAM and FRBR (which will be a high profile exemplar for others to follow)
- the Semantic Web community get a significant pool of well thought-out metadata terms to re-use
- there is wider uptake of RDA
KC: What does it mean that there will be a "formal RDA Element vocabulary?"
D: It will look something like the Dublin Core registered terms. They will be both human readable (as displayed in a browser) and machine readable (in a format like RDF). Try clicking on this link, and you can see on the right the different machine-readable formats.
KC: What happens now to the "tome" that has been developed through the RDA process?
D: The "instructions" as we see them in the RDA documentation, will not be affected. The element vocabulary, the formal vocabulary, will be separated out, and the documentation will point to the formal vocabulary terms. Many users of the documentation will not see the formal element vocabulary and may not know that it exists. The vocabulary, however, will be behind the online tools that are being created. This will make it easier to create a system that allows people to click on a term and get a definition or to see the related hierarchy.
Having the formal vocabulary means that there can be a testbed for the many and complex relationships that are being expressed in RDA, FRBR and FRAD.
KC: How is this going to be accomplished? It looks like a lot of work.
D: There will be an effort to find funding to accomplish this, but the work itself will be done with the combined efforts of the RDA and Dublin Core communities. Some of the work, such as the RDA vocabularies, is already begun.
This is nothing short of revolutionary, at least in comparison to where we started in the late 1990's on a revision of AACR2. Imagine a library that is seamlessly integrated with the semantic web.... we seem to be on our way.
