all – to day a little more about application profiles. Thy are basically the mixing and matching of existing schemes, and keep us from reinventing the wheel over-and-over. There’s a lot of good work, really GOOD work that’s been done w.r.t. scheme design, metadata standards, etc., and we duplicate efforts.
RDF app. profiles can allow us to leverage this work in a more intelligent way. The Dublin Core community is often perceived as being just about the basic Dublin Core metadata element set (15 metadata elements). This is hardly the case, there is a lot of really good metadata work taking place there.

All,
In order to ensure that the metadata is encoded in an interoperable fashion (e. g. for cross-repository search and federation) we could consider implementing an RDF application profile. A team around Antoine Isaac and Karen Coyle are currently working on this within the Dublin Core community [1].

Gary, all –
I’m in the ‘horses for courses’ camp. If the end-user wants a human-readable list of datasets likely to be of use then minimal metadata (DC type) is fine. If the end-user wishes to autonomically have a homogeneous answer from multiple heterogeneous datasets then metadata with formal syntax and declared semantics (handling multilinguality also) is required. This is far from minimal (and to my knowledge only achieved in restricted domains but others may know better).
The question arises ‘is it worth providing more than minimal metadata’? If only minimal metadata is provided the end-user has to do a lot of manual work to achieve homogeneous access across heterogeneous datasets. If the provider inputs/stores more than minimal metadata then s/he has a lot of work (hopefully reduced by re-utilising existing metadata and utilising text/data mining of the data) but the end-user has an ‘easy ride’.
Best

One of the issues discussed at a recent RDA outreach workshop was how people felt about “minimal metadata.”
Some cautioned that it is potentially a bad idea, while a pluratity seemed in favor of it and could point to good outcomes using .
An example provided at the workshop was that of the Dataset Descriptions: HCLS Community Profile discussed by Michel Dumontier (Stanford). The idea here is to:
Develop a guidance note for reusing existing vocabularies to describe datasets with RDF – Mandatory, recommended, optional descriptors – Identifiers – Versioning – Attribution – Provenance – Content summarization * Recommend vocabulary-linked attributes and value sets
see http://www.w3.org/2001/sw/hcls/notes/hcls-dataset/
We were perhaps more uniform on the idea expressed by NIST’s Bob Hanisch that maximum MD causes a problem since people won’t “use it.”
