ObjectSecurity is the official author, maintainer, and supporter of the Semantic Xwiki open source project. The Semantic XWiki project integrates XWiki, a state-of-the-art Wiki technology project with Apache Jena, the latest semantic web technology (supporting OWL, RDF, SPARQL). The aim of the first phase of the project was to provide the basic integration of the two technologies with the best support for the Wiki programmer or advanced user. The project supports a set of custom defined XWiki macros which are usable for XWiki application programmers or advanced user to create custom semantic-based XWiki applications. These macros are used instead of semantic tagging based on the content of the wiki or any kind of automatic semantic search. ObjectSecurity uses the technology for semantics/ontology-driven cyber security purposes and other semantics/ontology-driven purposes.
