Version: 5.5.0
Indispensable tool for editing web ontologies. Supports the full OWL 2 specification plus SWRL rules. Extendable via a large number of useful plugins (providing additional editing, reasoning and query capabilities, among others). Still actively developed, with a large community behind it and it's open source.
