Re: [Bigdata-developers] Iterator over namespaces?

Fred, I've added logic to NanoSparqlServer which shows how to do this. See the "getNamespaces()" method in that class. There is now a URL query parameter "showNamespaces", e.g., "http://localhost:80/status?showNamespaces", which will write the namespaces into the HTTP response. The getKBInfo() method in that class was also modified to write out all the properties for the triple store. Both of those are read operations against the global row store using the RelationSchema.
