OWL provides an owl:imports construct that allows people to combine ontologies by including all the axioms contained in an external ontology in one’s local ontology. But then , everything in the transitive closure of the imported ontology becomes a part of the local ontology. Have people found this to be a problem for their work and if so what are best practices around it?

There seem to be a number of efforts to get around this,such as modular approaches  but I'm not sure what the experience has been with them.The

Perhaps others have some experience with what these discuss.
