= ResourceStorage =

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

stores all resources of the user, these are typically data extracted from the filesystem, address-books or e-mails:
 * files
 * addresses
 * e-mails, etc.

Its filled by Aperture and the ApertureSynchroniser. Sometimes applications add a resource here before they are tagged using the TaggingApi, so also the TaggingApi will store here.

= Features =
 * mass inserts using the {{{addResource()}}} and {{{removeResource()}}} methods.
 * fulltext search
 * similarity search (at the moment using lucene, switching to catwiesel soon)

== Fulltext-querying ==
From inside gnowsis (using Java code inside the gnowsis server), you go like this:

{{{ 
ResourceStorage s = Gnowsis.getResourceStorage();
Iterator<Tag> it = s.search("hello");
// iterate through uri/label/type returned inside the tags.
}}}

== Sparql, SERQL and RDQL querying ==
From inside gnowsis, you can access the Sesame repository directly using the {{{ResourceStorage.getRepository()}}} method. '''All Sesame2 querying works''' on that. If you feel unhappy with Sesame, use our Jena wrappers for querying:

{{{
ResourceStorage s = Gnowsis.getResourceStorage();

// Sesame querying:
s.getRepository().....

// Jena querying
public ResultSet doSelectQuery(String query, QueryLanguage querylanguage)
public Model doConstructQuery(String query, QueryLanguage querylanguage)
}}}

== Adding resources using web-interface ==
At the moment you cannot add resources to the resource-storage from the outside. You can use the TaggingApi to do this, though.
{{{
TaggingApi.ensureResourceIsInStore(String resourceUri, String label, String typeUri, String fulltext, String metadataXML)}}}

== Browsing the contents ==
The best way to see what is in the resource-storage is to use the local sesame web interface.
 * go to http://localhost:9993/sesame1
 * login
 * select the '''resource''' repository
 * press explore


= Implementation decisions =
Named graphs are used to seperate single resources, each !ResourceManifestation? gets a named graph.
