Re: [Bigdata-developers] Working with prefixes/namespaces

[Brad B. <be...@sy...>]

Alex,

The namespace abstraction allows you to host multiple knowledge bases, each
of which having potentially different configuration options (triples, RDR,
inference, quads, etc.), in a single Blazegraph server instance.  Here's
some of the configuration options  [1].  There is a default namespace
("kb"), which is used if no namespace is specified in the SPARQL endpoint.
In the example below [A] and [B] are equivalent.  [A] uses the default
namespace.  [C] specifies using the "biology" namespace.

[A] http://localhost:9999/bigdata/sparql

[B] http://localhost:9999/bigdata/namespace/kb/sparql

[C] http://localhost:9999/bigdata/namespace/biology/sparql

Thanks, --Brad
