Many operations require information from the application and domain ontologies. Making that information available is the role of the JenaEIOntModel (eagle-i-model-jena: org.eaglei.model.jena) at the back end.

For the purposes of datatools and SWEET, all information about the ontologies is encapsulated in these classes.

Getting data of various kinds (AbstractRepositoryProvider and its subclasses)

In order to allow a user to enter and edit data, SWEET must retrieve data in various forms from the ontology and repository. The relevant interfaces are found in org.eaglei.datatools.provider, and implementations in org.eaglei.datatools.jena.
