Bio2RDF Should we do it ?
Bio2RDF Architecture XML KGML CSV RDF Bio*2RDF converter Sourceforge side Ready to use files available with CVS User side
The problem ● Too many knowledge sources available for life science scientists ● Too many formats (text, XML, HTML) ● New source each day with specialized tool or web interface ● Integration problem recognised by global community
One early solution ● Semantic web browser (BioDash) are in development - so what can we do in the mean time ? – Adopt the semantic web format (RDF) – BioPax, Swissprot already offer RDF documents – Select a strong knowledge tool to work with (Protege) – Convert popular knowledge source to RDF in a community effort (Bio2RDF)
What is RDF ● Simple XML format from the semantic web initiative of the W3C made of triples ● RDF is the predecessor of OWL ● Many tools from the computer science community already read RDF (Protege) ● Inference tools are available (RACER, FACT)
GO definition in RDF
What is Protege ● Mature software to work with knowledge bases and ontologies ● Open source Java application used by 30,000 users community ● Ontology editor with GUI interface ● It support RDF, natively ● Many specialized plugins – Visualisation – Import/Export to specialized file format ● Gives the experience of semantic browsing
Protege+RDF demo ● GO ontology in Protege ● BioPAX from the Reactome glycolysis pathway converted into RDF for visualisation with the TouchGraph plugin ● GO + MGI – An example of merging knowledge

Bio2RDF.sourceforge.net ● A central repository for tools to convert bioinformatics data and knowledge bases to RDF format ● A repository of ready to use RDF files for loading in Protege or other semantic tools ● A place for the semantic web life science community to develope and grow
