Re: OWL 2 Quick Reference Card

[Jie Bao]

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@...)

This ([1]) is just so cool - it even got me to read it properly.

Which did get me pondering on why people might feel the need to re-write
Universal/Empty to Top/Bottom, making people have to just remember the
terms, since hopefully many users will have no idea why.

But it is really good, and even seduces me into thinking I might understand
it.

Thanks
Hugh
