hi jim,
great progress!
and i believe you are right about how limpopo parser stores the
protocols, i've included tony, who's been the lead developer of the
parser on the email and he might be able to shed some light.
if tony can outline a plan, i might have the time to correct this.
cheers,
michael

I have checked in a first (complete) cut for magetab2magerdf 0.9a.
Everything should be there, both IDF and SDRF, but I haven't
tested against a wide range of files yet. This is alpha software.
*Features:
*
* Conversion of nearly all (see known issues) data from IDF
and SDRF MAGE-TAB files into RDF.
* RDF is compliant with the MGED Ontology, with minimal
additional classes and properties.
* RDF conforms to DAG structure with direct links between
nodes (has_derivative and has_derivation_source) as well as
through ProtocolApplication instances.
* Terms and Term Sources are automatically mapped onto the OWL
Classes and Individuals that are available, and will "guess"
at URIs for terms that do not map onto an actual OWL ontology.
* Validation of Terms and Term Sources through the above
mapping process. If an ontology is loaded and there is no
term available in it, the converter errors out.
*Known issues:*
* Units for characteristics and factor values are ignored. I
assume that if there is a unit type then these are
non-terms, and should be handled differently. Ideas?
* All protocols listed for a given SDRF node are used to
produce all child nodes of that node. As I mentioned before,
I'm not sure how I'm supposed to distinguish these in the
Limpopo API.
*Examples:*
* Example RDF is at
http://magetab2rdf.googlecode.com/svn/trunk/magetab2magerdf/examples/E-MEXP-986/E-MEXP-986.rdf
* Add-on MAGE-OM ontology is available at
http://magetab2rdf.googlecode.com/svn/trunk/ontologies/mage-om.owl
*Availability:* http://code.google.com/p/magetab2rdf/

Jim,
Quick request re. the RDF documents holding the RDF triples, you need to
add a relation that connects the RDF Documents to its contents e.g.,
using one of the Topic oriented properties from Dublic Core, FOAF,
Bibliographic Ontology etc.
The current effect of not doing the above is demonstrated here (sadly
this problem is way too common across the RDF data publishing realm):
1. http://bit.ly/5I62KG -- Nothing shown here since the Page Description
seeks to describe the RDF doc, and then from the doc description expose
RDF graph its hosts
2. http://bit.ly/7v11ym -- Data is Explorable here because the Browers
is processing the RDF doc contents.
Everyone: Happy New Year!
