= PimoStorage =

The PimoStorage stores the user's Personal Information Model. Basically, thats all ontologies, tags and wiki pages, and the relations to resources.

* [source:branches/gnowsis0.9/gnowsis-server/src/java/org/gnowsis/repository/PimoStorage.java Sourcecode PimoStorage.java]
* [http://www.gnowsis.org/statisch/0.9/doc/gnowsis-server/javadoc/org/gnowsis/repository/PimoStorage.html Javadoc PimoStorage.java]

Usage example:
{{{
// I write a triple to the pimo
Repository r = Gnowsis.getPimoStorage().getRepository();
Transation t = r.startTransaction();
// add something
t.add(new StatementImpl(s, p, o));
t.commit();

// do fulltext search on pimo, using lucene query language
Iterator<Tag> tagI = Gnowsis.getPimoStorage().search("Hello*");
while (tagI.hasNext())
{
  Tag t = tagI.next();
  System.out.println("found thing: "+t.getUri()+ " with name "+t.getName());
}
}}}



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.
