Re: [topbraid-users] Base URI in TopBraid

[Scott Henninger]

Peter; I think that explains it pretty well.  TopBraid has always had a named graph architecture, just like triple stores.  But a problem is that text serializations don't have a way to define the graph name, except for the base URI, which turns out to work nicely and transparently.  To the extent that RDF 1.1 specifies different ways of specifying named graph, and RDF files comply, we will adopt those standards in due time. -- Scott On 1/22/2013 11:20 PM, Peter Ansell wrote: On 23 January 2013 14:07, Simon Cox <dr.shorth...@gmail.com> wrote: While trying to move RDF data between systems, we have found that TopBraid appears to use a non-standard way to specify the base URI in its Turtle mode. The documentation is clear: on the Help page TopBraid Composer > RDF and TopBraid > Named Graphs and Base URIs in TopBraid it says base URI that identifies a graph is saved within a file using one of the following types of statements: Hi Simon, That almost sounds like it identifies a graph, in the same way as SPARQL Graph's, which are going to be in RDF-1.1, but are not in RDF-1.0. A graph is separate to the normal interpretation of base URI, as it encompasses a set of statements, but does not provide a base for relative URIs. To fully support graphs you would need to move to using a quads format, with either TriX (RDF/XML+Graphs), TriG (Turtle+Graphs) or N-Quads (N-Triples+Graphs) as possible alternatives.
