Java Package Ontology (e.g. to facilitate Ptolemy component access)
Ptolemy has a number of neat components that are currently very hard to get to.
For example, MonitorReceiverContents under ptolemy.vergil.actor.lib is nice for certain runtime monitoring and "debugging" purposes (thanks Edward! :)
If we created a virtual "Java Package Ontology" (JPO), i.e., one that simply considers maps containment as concept subsumption, then this would allow us to browse and search (!) any and all otherwise unannotated components (Ptolemy or Kepler) easily.
It seems this would make the good (bad) old habit of InstantiateComponent / InstantiateAttribute superfluous.
