Folks, While trying to learn more about RDF, OWL and the Semantic Web stuff to try to apply it to our GUID discussion, I came across some nice presentations on the Net: http://www.w3.org/Consortium/Offices/Presentations/SW_QA/#(14) - Semantic Web Q&A http://www.w3.org/Consortium/Offices/Presentations/RDFTutorial/ - Tutorial on Semantic Web Technologies I hope you find them as useful as I did. Enjoy, Ricardo _______________________________________________________ Yahoo! Acesso Grátis: Internet rápida e grátis. Instale o discador agora! http://br.acesso.yahoo.com/
