OWL 2 Reference Card released
We’re pleased to announce the OWL 2 Reference Card [1]. The Card is meant to be a “cheat sheet” of OWL 2 features printable on a single piece of paper (on both sides). It is based on the OWL 2 Quick Reference Guide [1], which is now a Proposed Recommendation [2] in the OWL 2 Web Ontology Language document set.
Background: OWL 2 [4] is an extension to OWL 1 with a few new functionalities. Some of the new features are syntactic sugar (e.g., disjoint union of classes) while others offer new expressivity, including:
* keys;
* property chains;
* richer datatypes, data ranges;
* qualified cardinality restrictions;
* asymmetric, reflexive, and disjoint properties; and
* enhanced annotation capabilities
Comments and suggestions to the Card are welcome (please send to public-owl-comments@w3.org)
