The Semantic Pingback mechanism is an extension of the well-known Pingback method, a technological cornerstone of the blogosphere, thus supporting the interlinking within the Data Web.
More Information on Semantic Pingback is available at http://aksw.org/Projects/SemanticPingback
In order to enable Semantic Pingback for OntoWiki you need to make sure that
- the Linked Data Server extension is enabled (should be enabled by default, extensions/linkeddata),
- the Pingback extensions (extensions/pingback) is enabled.
The extensions can be enabled by the ExtensionManager (in the Extras menu or <your-ow>/exconf).
