OntoWiki and Powl

OntoWiki is a semantic collaboration platform for the development of Semantic Web knowledge bases. OntoWiki enables large distributed communities to collaborate on a semantic level, by allowing users to contribute small structured knowledge pieces, which stitched together may result in comprehensive knowlegde bases. Powl is Web-based ontology authoring and management solution for the Semantic Web. Both expose an extensive API for PHP programmers.

        Release Notes: This release resolves bugs and introduces minor new features and enhancements. Some of them were requested and inspired by first medium scale Powl application projects.

Widgets for editing arbitrary nodes and literals (including language and datatype) added. Search in instance lists added. The instance editor selectively shows only properties with values.
