Re: BioRDF Telcon

I'm following a similar strategy, but have been folowing the MGED
ontology where possible. I've finished aligning the IDF portion, and
have started on SDRF. MGED ontology is missing a property and class
for what is often termed as ProtocolApplication, which usually serves
as an edge between derived from and derived nodes, while linking to
the protocol used for the derivation. I am planning on creating this
link in a MAGE extensions ontology, but would like to vet the
structure here:

ProtocolApplication is a class.

New properties:

has_derivation_source
has_derivative

And then ProtocolApplication would have the restrictions:

has_protocol some Protocol

I don't put, domains, etc. on the derived properties to allow use in
directly describing derivations if people so choose. There is no
superclass for all nodes that can be derived or derived from, so I'm
not bothering with restrictions for those, although I could add a
union restriction to it.

If this structure us acceptable to people, I can publish the ontology
for general use pretty quickly, and let us work from the same data
structure. I would appreciate any feedback.

The challenge, though, has been coming up with the predicates to formalize the relationships between the various elements. I'm using the XML structures fir IDF/SDRF etc. at http://magetab-om.sourceforge.net to automatically generate the structure that will contain the data. My plan is to then create the RDF triples that use the attributes described in those documents and populate them with the data from the MAGE-TAB java object created by Limpopo.

That's also what I concluded after looking at the data structure created by Tony Burdett's Limpopo parser. However, having the raw data as linked data is already a great start! Kei, should I be looking into Taverna in order to reprocessed the raw files with a traceable analysis workflow?
