What is OntoWiki? What can it do for you?

OntoWiki is a semantic application as well as a framework which acts as a hardened basement for your application in the Semantic Web context. One of its main purposes is to assist you managing your knowledge. Knowledge means here machine readable data organized as RDF/XML, Notation3, Turtle as well as Talis(JSON). You organize your knowledge using an feature-rich user interface managing classes, properties and resources. If you don’t know what is this all about, please have a look here (and associated pages) before continue reading. Furthermore what OntoWiki can do for you:

  • Providing feature rich user interface to helping you organize and manage resources, relations between resources, classes, … . We heavily use modern browser technologies to give you a smooth user experience.
  • It is a Linked Data server for you data as well as a Linked Data client to fetch additional data from the web
  • It is a Semantic Pingback Client in order to receive and send back-linking request as known from the blogosphere
  • You can use the backend you know to store your data, because OntoWiki is backend independent, which means you can save your data on a MySQL database as well as on a Virtuoso Triple Store

But thats not all, OntoWiki provides a rich set of extensions. In the following a collection:

  • Wikipedia like Wiki’s: create wiki pages using Markdown and have to possibility to attach wiki pages to existing resources
  • PubSubHubbub to spread your local knowledge changes over the web and be synced with foreign sources
  • Extension named CubeViz for visualization of statistical data which are organized in the DataCube format. OntoWiki + CubeViz are already in use for the Open Data portal of the European Union!
