= PimoStorage =

all things of the user, the pimo ontology itself, the imported domain ontologies, the things of the user, links to occurrences, wiki pages, wiki names, all.... 

Interface: [source:branches/gnowsis0.9/gnowsis-server/src/java/org/gnowsis/repository/PimoStorage.java PimoStorage.java]

Features: 
 * text indexing (using the lucene SAIL, configured to what is indexed). 
 * Reification is used to say when a triple was inserted when its a user triple like pimo:occurrence.
 * Storage is !NativeSail + luceneSail

= Using Context in the PIMO =
The fourth part of a triple - context - can be used differently in the pimo, we haven't decided yet how. Possibilities for context are:
 * use context to seperate between domain ontologies. Context = uri of the InformationModel (not namespace, btw).
 * use context for each triple: each triple has a context, context is a random uri. Uri is annotated saying who created it when in which domain ontology. This helps updates (seing "what has changed since yesterday").

= Domain Ontologies =

The user might decide to write a domain ontology or download one from the web. If that happens, the domain ontology (example: beer ontology) will be glued into the user's pimo.

So we have to support:
 * creation of domain ontologies
 * deletion of domain ontologies / removing of instances that were created in my Pimo using domain ontology
 * editing of domain ontology.
 * updating of domain ontology from a changed remote version.
