Continuing the Conversation: RDA Vocabularies in the Semantic Web

By Daniel A. Freeman |

Earlier today, we held the second session of our three-part workshop, Using RDA: Moving into the Metadata Future. The session, RDA Vocabularies in the Semantic Web with Diane Hillmann, completed the successful series. The following are resources and questions for discussion or explanation. Diane Hillmann will be chiming in via comments--please join her.

The following resources or examples were referenced during the presentation.

Property and value vocabularies are registered in the Open Metadata Registry (formerly the NSDL Registry)

For an example of  element in the Open Metadata Registry, see  RDA Group 1 Elements: Book Format (Manifestation)

Below are a few question that Diane will address in comments.

You said we would be free of the tyranny of records.  It seems that the Semantic Web is pulling info from any number of sources--how does it decide which sources to use and reduce the sources to a manageable level?

How do you envision URIs being assigned to entities? And do you see them being assigned to works or manifestations, for example?

There is a lot of anxiety around whether frontline catalogers need to understand these abstract concepts. Knowing that the ultimate goal is that we’ll be working in some kind of cataloging tool, what are the most important concepts for catalogers to understand to participate in the process now? For example, what do we need to know when we’re talking with vendors?

Does anyone know of any vendors actually working right now to build any applications using RDA as expressed in RDF?

Are these vocabularies describing fields, like "tag" names, which can be used to carry content and related to each other as well as to to specific items being described?  Please give a little more context for the vocabularies and their use.

Could a diagram or chart or something possibly be drawn illustrating the relationships between RDA, RDF, XML, FRBR, FRAD,.  It would be helpful to visualize these new concepts and how they relate to each other.

How is Dublin Core related to RDA/FRBR? Is DCMI doing its own DC-RDA application profile?
