In principle, owl:imports can be as fine-grained as you like; you could have a bunch of named graphs with a single triple apiece. That's in principle, but in practice it doesn't deviate that much. If you have a tool that make managing multiple named graphs / OWL files easy, you can split your ontology into a large number of pieces, and manage them with owl:imports. We have been doing this successfully for year. Back the the Protege days, managing a dozen such modules was an onus. We typically manage several dozen nowadays, and occasionally in the hundreds, without undue stress on project management. Furthermore, within SPARLQMotion, you can define (with a SPARQL CONSTRUCT) just what part of an ontology you are really interested in, and pass that on to the next SM module. This has the advantage of keeping within standards as closely as possible (eg, SPARQL doing all the heavy lifting for defining sets of triples), while providing capabilities of the sort you are describing. But of course, Holger's comment about extra plugins is the real answer - even if I am correct that with SM and our multiple ontology management infrastructure, we can support many of the same requirements, you might still want to support e-connections etc. Dean --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TopBraid Composer Users" group.
