OntoWiki

facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.

As of version 1.x (currently in alpha state) the project has been extended to the OntoWiki Application Framework that can be used to tailor OntoWiki for domain-specific use cases or customize its generic views to suit more specific needs.
