We are happy to announce the beta release of RDFaCE (RDFa Content Editor). RDFaCE is an online text editor based on TinyMCE. It supports authoring of RDFa content.
In addition to two classical views for text authoring (WYSIWYG and HTML Source Code view) , RDFaCE supports two novel views for semantic content authoring namely WYSIWYM (What You See Is What You Mean) and a Triple view (aka. Fact View).
The WYSIWYM displays semantic annotations on top of classical WYSIWYG view which is widely used for Web content creation. It uses dynamic CSS stylesheets to distinguish semantic content from normal content.
The triple view is another semantic view which only shows the facts (i.e. triples) stated in the text. RDFaCE provides a syncronization between these four views so that changes in one view cause respective changes in the other views.
Another important RDFaCE feature is the combining of results from multiple NLP APIs to facilitate the semantic authoring process with automatic annotations. This feature provides an initial set of annotations for users that can be modified and extended later on.
