Software provisioning ontology

swpo.owl

The swpo.owl ontology imports a set of legacy ontologies axiomatizating the domain of software components, available @ cos.ontoware.org.

Core concepts of the ontologies are Library and Component, both subclasses of a generic SWObject. It is useful to capture a group of different versions for the same component, identified by the same instance of SWObjectID.

A component/library will have a set of TaskClass instances, identifying "what" the piece of software is going to do (logging, persistence, nlp, parsing, etc). This leads to infer a "weak" functional equivalence between components.

It could also comply to some specification (more or less formally defined), for instance restricting the input format, or the output format, or implementing a particular framework specification, the latter yielding a much more strict definition of functional equivalence.

It could be useful to enable search features driven by non-functional grouping criteria (i.e.: find all jakarta projects), so the notion of belonging to a NonFunctionalClass has been captured in the model as well.

The notion of License-style is captured in the model, at the moment as a simple one-to-many relationship. It could be nice to have in the future a more granular description of a license, to allow much smarter search criteria.

Only Maven and OSGi legacy repositories fall into GSoC's scope, but adding interaction capabilities with other legacy systems will be quite straightforward.
