The context (named graphs in LMF, formerly "knowledge space" in KiWi) service offers convenience functions for working with LMF Contexts. Low level manipulation of contexts is offered by TripleStore.

A context or (other name) named graph represent a own graph for a separation of the whole data in the context. In other words: the relationship between triples and a context is a 1 to N relationship. Every triple is though the context connect to exactly one context.

Every context has own access rights, triples, reasoning rules and other metadata.

You can create contexts for user, for imported ontologies, own created content, inferred triples and system data

every new triple without information of a context is connect with the context to the default context
