Investigating OWL tools

From ClioKnows

A Basic list of OWL tools:

Editors: Protege (with OWL plugin), SWOOP

Reasoners: Pellet, KAON2, Racer, FACT++

Databases: Sesame, Tucana

Some Comments: In terms of editors, Protege is probably the biggest, but SWOOP also looks good. There are also some up-and-coming projects that might be useful - IBM produces an OWL editing plugin for Eclipse, and there's a new editor by the old lead dev. of Protege.

In terms of reasoners, Pellet would be my choice. It is the only one that seems to do all of OWL-DL, and is available under an OSS licence. As well as the DIG interface, it also has an API (which allows you to do more than just via the DIG interface) and a good mailing list.

Since CLIO is likely to be large, it would need some sort database. Sesame is probably the leader in terms of rdf-based databases, and has some inferencing included (although only upto OWL-Lite).
