Most of us in the library and cultural heritage communities interested in metadata are well aware of Tim Berners-Lee’s five star ratings for linked open data (in fact, some of us actually have the mug). The five star rating for LOD, intended to encourage us to follow five basic rules for linked data is useful, [...]

Over the past weekend I participated in a Twitter conversation on the topic of meaning, data, transformation and packaging. The conversation is too long to repost here, but looking from July 11-12 for @metadata_maven should pick most of it up. Aside from my usual frustration at the message limitations in Twitter, there seemed to be [...]

The RDA Development Team started talking about developing training for the ‘new’ RDA, with a focus on the vocabularies, in the fall of 2014. We had some notion of what we didn’t want to do: we didn’t want yet another ‘sage on the stage’ event, we wanted to re-purpose the ‘hackathon’ model from a software [...]

The planning for the Midwinter Jane-athon pre-conference has been taking up a lot of my attention lately. It’s a really cool idea (credit to Deborah Fritz) to address the desire we’ve been hearing for some time for a participatory, hands on, session on RDA. And lets be clear, we’re not talking about the RDA instructions–this [...]

Many of you have heard me say “Time flies, whether you’re having fun or not”–and that has certainly been the case since I got back from the NISO Roadmap meeting a few weeks ago. Somehow, with my head down, I missed part 1 of Roy Tennant’s post “The Post-MARC Era, Part 1: “If It’s Televised, [...]

I saw the announcement a few weeks ago about the demise of MARBI and the creation of the new ALCTS/LITA Metadata Standards Committee. My first reaction was ‘uh oh,’ and I flashed back to the beginnings of the DCMI Usage Board. The DCUB still exists, but in a sort of limbo, as DCMI reorganizes itself [...]

Metadata is produced and stored locally, published globally, consumed and aggregated locally, and finally integrated and stored locally. This is the create/publish/consume/integrate cycle. Providing a framework for managing metadata throughout this cycle is the goal of the Dublin Core Abstract Model and the Dublin Core Application Profile (DCAM/DCAP). The basic guidelines and requirements for this [...]

By-passing taggregations identifies those MARC21 variable data field tags whose level 0 RDF properties, representing individual subfields, can be used generally in data triples and mapping triples without losing information and the semantic coherency of the record. These tags have subfields which are independent of one another, with no need to keep them together if [...]

If we were asked (as we sometimes are) what we’d like to see develop as a result of the BibFrame effort, the emphasis in our answer would have both technical and social aspects. First, given the technologies developing in several different places and considering what we can do now to bring Linked Open Data into [...]

The methodology of treating MARC21 variable data field tags as aggregated statements in RDF is discussed in Taggregations. There are some circumstances when this approach is redundant and level 0 RDF properties based on individual subfields can be used directly in MARC21 data triples that are semantically complete and coherent, and in mapping triples relating [...]
