There were a number of references to the UMBC Semantic Web Reference Card – v2 when it was first posted about a month ago. Because it is so useful, I chose to bookmark the reference and post again later (today) after the initial attention had been forgotten.
According to the site:
The UMBC Semantic Web Reference Card is a handy "cheat sheet" for Semantic Web developers. It can be printed double sided on one sheet of paper and tri-folded. The card includes the following content:
- RDF/RDFS/OWL vocabulary
- RDF/XML reserved terms (they are outside RDF vocabulary)
- a simple RDF example in different formats
- SPARQL semantic web query language reference
- many handy facts for developers.
The reference card is provided through the University of Maryland, Baltimore County (UMBC) eBiquity program. The eBiquity site provides excellent links to semantic Web publications as well as generally useful information on context-aware computing; data mining; ecommerce; high-performance computing; knowledge representation and reasoning; language technology; mobile computing; multi-agent systems; networking and systems; pervasive computing; RFID; security, trust and privacy; semantic Web, and Web services.
The UMBC eBiquity program also maintains the Swoogle service. Swoogle crawls and indexes semantic Web RDF and OWL documents encoded in XML or N3. As of today, Swoogle contains about 350,000 documents and over 4,100 ontologies.
The Reference Card itself is available as a PDF download. Highly recommended!
