Java OWL Persistence API
Currently, JOPA tracks changes during transaction and propagates them to a transactional snapshot in the OntoDriver. This requires a way to be notified of changes to managed entities. This was...
As a developer, I want the JPA [`orphanRemoval`](https://docs.oracle.com/cd/E19798-01/821-1841/giqxy/index.html) attribute to be supported by `@OWLObjectProperty`. Orphan removal works by removing the instance that was removed from an attribute value from the...

As a user, I want to be able to easily create objects (DTOs) from SOQL query results. JPQL allows specifying a constructor that is passed the projected query variables and...
The `includeExplicit` attribute of the `@Inferred` annotation is not heeded at the moment and such attributes always contain both explicit (asserted) and implicit (inferred) values. A proper implementation of this...
As a user, I want to be able to use a [Stardog](https://www.stardog.com/) repository from my JOPA-based application.
As a user, I want to be able to use Virtuoso server as storage. This will, according to documentation, require a custom OntoDriver implementation using either Virtuoso's RDF4J or Jena...
As a developer, I often store entities of a certain type in the same repository context (RDF named graph). However, currently, this has to be configured at runtime using descriptors....
When an entity is updated (merged into the persistence context) and the transaction is committed, the second level cache updates only the updated entity itself. However, there may be other...
Subproperty hierarchies are quite common in data and are one of the fancy features that might well distinguish RDFS ontologies from Java object model. As a user I want to...
