Software / Semantic Wiki COW

COW is a semantic wiki using KAON as backend that supports collaborative evolution of ontologies by means of versioning, transactions, and management of simultaneous modifications. In wiki pages, ontology information can be used to render dynamic content as well as answer user queries.

Developers: Jochen Fischer, Zeno Gantner, Steffen Rendle, Manuel Stritt

System Requirements

  • JDK >= 1.4.1
  • Database: e.g. PostgreSQL or MSSQL
  • Web Application Server: Tomcat >= 5.x

Download the binary files (see above).

  • Use the schema-sql files to create the database schema. Use pgsql72.sql for Postgresql or schema.sql + specific schema-file for any other database. For mWiki use qikiwiki.sql.
  • Copy sw1 AND sw2 to tomcat/webApps, restart tomcat.
  • Run sw1/install.jsp and sw1/qwinstall.jsp to configure COW and mWiki.
  • Run sw1/index.jsp. Try [concept=person] in the wiki to get a link for the ontology-editor. To run the ontology-editor directly run sw1/editor.jsp.

For the syntax in mWiki see http://radeox.org/space/snipsnap-help.
