== OntoWiki 0.9 Frontend Changes ==

- *RDFa widget editing* This feature separates the visualization of the 
RDF data in the browser from the statement editing component by using RDFa 
annotations inside the view and JavaScript editing widgets which are 
sensible to the type and context of the edited data.
- *Extension architecture* with support for components, themes, 
datawrapper, translations and generic plugins: Most of OntoWiki's 
functionality is implemented as extensions now, thus keeping the OntoWiki 
core very small.
- *Authentication support* for local sioc:Users, FOAF+SSL WebIDs and OpenIDs.
- *Support for LinkedData* both as server and consumer (see data gathering 
backend below).
- *Translations* in English, German an Chinese


== OntoWiki 0.9 Backend Changes (Erfurt) ==

- Separation of the Semantic Web API Erfurt from the OntoWiki core
- Support for *multiple SPARQL RDF stores*: Implementations are available for 
Virtuoso and ZendDB (i.e. MySQL), allowing installations with support for 
millions of triples.- *Pattern based query cache*: In order to improve the 
performance of Semantic Web applications, we developed an approach for caching 
SPARQL query results and complete application objects, which is sensitive to 
knowledge store updates.
- *Data gathering*: Support for plugable data gathering backends e.g. for 
LinkedData gathering, DataWrapper for Twitter and Musicbrainz or Exporter e.g. 
for EXIF data
