v8 v9 8 8 We need rdf storage in different parts of gnowsis. Each storage has a reason and different requirements. 9 9 10 * configuration store: part of gnowsis-config api. Is used to configure the services (hostname, passwords, services, etc). It has to be stored in an N3-RDF to be able to hack it if something goes wrong. This relates to ticket:107 11 * pimo-store: 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.... Features: text indexing (using the lucene SAIL, configured to what is indexed). Named graphs are not really used? Reification is used to say when a triple was inserted when its a user triple like pimo:occurrence. 10 * configuration store: part of gnowsis-config api.

Reification is used to say when a triple was inserted when its a user triple like pimo:occurrence. Pimo-store replaces the Central-Rpository! 12 12 * resource-store: stores all resources (pimo:ResourceManifestation) of the user. Its filled by Aperture and sometimes by the applications that want to add a few resources before they are annotated (using pimo:occurrence). No other parts of pimo go there, especially no pimo:occurrence links. Needs fulltext indexing using LuceneSail(configured by Aperture ontology and PIMO-ResourceManifestation) OR Catwiesel. Named graphs are used to seperate single resources, each ResourceManifestation gets a named graph. 13 * service-data-store: used by services like Thumbnailservice, IconService, ContextService, etc to store the RDF data they need to work. Named graphs are used to seperate the services. No text-indexing needed (no LuceneSail). 13 * service-data-store: used by services like Thumbnailservice, IconService, ContextService, etc to store the RDF data they need to work. Named graphs are used to seperate the services. No text-indexing needed (no LuceneSail). Interfaces: Sesame2, Jena ModelDatabase..? 14 14 15 15 Startup sequence for the stores is: … … 17 17 * then service-data-store to get the config data for the services available 18 18 * then resource-store and pimo-store. 19 20 Common Interfaces we need in different services: 21 22 * Named graphs: in Sesame2 they are Repository/Sail, in Jena they are SPARQL-[http://jena.sourceforge.net/ARQ/javadoc/com/hp/hpl/jena/query/DataSource.html DataSource] 19 23 20 24 Logical Services to provide:
