Pushing an OpenDOAR

Andy Powell, 'Pushing an OpenDOAR':

Notes from Open Scholarship 2006

The value of the complexity of this profile is in the ability to express relationships. In most cases repositories do have the metadata, but have no common way to express the inherent relationships or exchange it (beyond oai_dc).

MODS One participant mentioned their decisionn to use MODS for repository metadata, because of internal expertise and the perception that DC wasn't rich enough.

Andy argued the case for Dublin Core:

  • simple DC is required for OAI so it makes sense to use it as the basis for all metadata
  • MODS is isolated from the Semantic Web and other metadata activities
  • compatibility with the Semantic Web is at the heart of DC
  • and the DCAM enables a more complex, richer metadata model to be specified
  • a confusion of mappings doesn't help with real interoperability
  • DC is highly extensible - this is real interoperability
  • people should look beyond interoperability with the library to the wider (semantic) web

There is RDA interest in DCAM as a basis, which is an interesting development for the library world.

There was also some discussion over the ambiguity between using hasAdaptation for another ScholarlyWork or adding a new Expression. It would be best to reach community consensus over such issues rather than enforce solutions in the profile.

Where, and at what entity level, does preservation metadata fit into the Profile? this was an interesting question and an area which would be interesting to look into.

There was a question about the lack of relationships between Copy and Agent. There is no explicit Agent specified for Copies, but an isPartOf relationship can be expressed to point to a service or repository making available the Copy.

Regarding e-theses metadata - representatives of European work in this area expressed interest. It was agreed the modelling approach might be applied to e-theses and the Application Profile might be extended or adapted for special publication types, such as theses.
