[http://www.sequenceontology.org/gff3.shtml GFF3] is a tab-delimited, ontology-aware format of genomic features. It should be beneficial to represent such genomic features in RDF so that we can exchange data and make queries with SW technologies.

Multiple tag=value pairs are separated by semicolons. URL escaping rules are used for tags or values containing the following characters: ",=;". Spaces are allowed in this field, but tabs must be replaced with the ?

'''Expected milestones''' * Mapping GGF2RDF (by Q1?) * Tools (in PERL, Python and Ruby) implementing such translation * Sample RDF data into a triple store (e.g. OpenVirtuoso) * Sample SPARQL queries * Divulgation (poster? or article?)
