Techniques for adding semantics to your metadata #1

Open leinfelder opened 10 years ago

leinfelder commented 10 years ago

Organizational Page: MetaSemantics Category: Data Science Title: Techniques for adding semantics to your metadata Proposed by: Ben Leinfelder Participants: Summary: If you're ready to add semantics to your metadata but you don't know where to start, this session is for you! We aim to examine existing - albeit nascent - efforts to annotate metadata and data to better express its meaning and make it more accessible for discovery and integration.

How do your keywords relate to semantic concepts? Can your CSV file really become Linked Open Data? Is RDFa the way to get there? So, everything's annotated...now what?

Perspectives from the rEML and SemantEco efforts are anticipated and encouraged.

@leinfelder I was psyched to see this one listed among the proposed ideas. Just to add fodder to collection of nascent examples, participants in this section might want to also take a look at what's being done with RDFa in the biodiversity informatics community (Ben, you may already be familiar with that).

One example I have been playing around with has been the NeXML standard for representing phylogenetic trees (see Vos et al for a quick intro), which has an RDFa mechanism built in (using a similar strategy to what we discussed doing with EML and additionalMetadata elements). It's pretty easy to add basic semantics (we have some examples using R in our current draft) and find real-world NeXML files that have them, e.g. from TreeBASE.

Working with @rvosa and @hlapp we've been exploring some cool examples of what one can do once the annotations are available in the context of the RNeXML package, e.g. Rutger's example with some SPARQL queries from R. Looking forward to working up some similar examples for EML...

I'm interested in this as I current participate in the Data on the Web Working Group at the W3C. I also work with metadata a lot and I think this sounds like a really good proposal.
