The base URI is a URI that is used to resolve a relative URI during parsing of a SPARQL query. A SPARQL endpoint is a service to which you can send protocol requests. This is identified by a URI. A named graph is a collection of triples identified by a URI. You can, if you wish, have a SPARQL service at <http://example.com/>, use that as your base URI, and have all of its triples stored in a graph named by that URI. That sounds like the situation you're talking about. More likely, you'll have no base URI (that's imposed by someone writing a query), a SPARQL endpoint of something like <http:// example.com/sparql/>, and be storing things in named graphs like <http://example.com/data/hans/>. The commonality comes from owning the domain. Can you be more specific? -R On 5 Jul 2006, at 9:22 AM, Hans Teijgeler wrote: > Hi, > > Even after reading all sorts of documentation we keep being puzzled > about the real difference (if any) between: > base URI > SPARQL endpoint > Named Graph > If we keep them the same our stuff works, but we would like to know > for 100% why, so what the relationships between these three > concepts are. > > Anybody out there who can shed some light on this? > > Regards, > Hans
