Fix OWLOntologyStorageException

I'm developing a Java application using owl-api. For testing I want to use a TestDataProvider to provide test data for unit-testing.

By default, an ontology is saved in the same place it was loaded from - in this case it was loaded from a remote IRI, and there's currently no support for saving an ontology directly to a remote URL.

You can work around this by specifying a target for your saveOntology() call, e.g.,

As can be seen in the comments of the post, my problem is fixed, so I thought I'd collect a closing answer here to not leave the post pending.

The actual solution: As explained here nicely by @UninformedUser, the issue was that I had conflicting maven package versions in my dependencies. Bringing everything in sync with each other solved the issue.

Incidental solution: As I wrote in the comments above, specifically defining 3.3.0 for the maven-assembly-plugin happened to solve the issue. But this was only chance, as explained here by @Ignazio, just because the order of "assembling" things changed, overwriting the conflicting package.

Huge thanks to both for the help.

Pellet 2.3.2 relies on OWLAPI 3.x.x and is not compatible with OWLAPI 4.x.x

There is a build compatible with OWLAPI 4 available on Maven Central https://search.maven.org/search?q=v:2.4.0-ignazio1977

There is also a much more recent build for OWLAPI 5, under the Openllet fork: https://search.maven.org/artifact/com.github.galigator.openllet/openllet-parent/2.6.4/pom

(2.6.4 is compatible with Java 8, same as the versions you're currently using.)

There is no inferred axiom generator that materialises the sameAs relations. You could write one yourself, based e.g., on InferredPropertyAssertionGenerator, or you can open an issue on the OWLAPI GitHub repo for the functionality to be added to the library.

Running inferences over the model was the missing step. Therefore, I needed to use the InferredOntologyGenerator class.

OWL-API rename does not remove old owl:Thing subclass in reasoner

Asked 2020-Sep-06 at 08:21

After renaming a class using OWL-API I'm not getting the list of subclasses I expect. I have created a small example to demonstrate.

The ontology contains 2 classes: Dog and Frisbee. I then rename Dog to Cat. After the rename, the list of owl:Thing subclasses contains both Dog and Cat.

Here is the rename-test.owl file:

Do not use the Structural reasoner. It is not meant for real world use and is likely keeping caches it shouldn't. Just write out the axioms in the ontology, there are few enough in this ontology for that to work.

QUESTION

What are the differences between JENA and OWL-API?

Asked 2020-Aug-06 at 08:26

Could you tell me what are the main differences between JENA and OWL-API?

...

ANSWER

Answered 2020-Aug-06 at 08:26

From the Apache Jena Website:

Apache Jena (or Jena in short) is a free and open source Java framework for building semantic web and Linked Data applications. The framework is composed of different APIs interacting together to process RDF data.

From OWL API Github:

The OWL API is a Java API for creating, manipulating and serialising OWL Ontologies.

Hence, Jena deals with RDF, while the OWL API deals with OWL.

What does this mean?

The short answer: Roughly you can see this as Jena dealing with data and the OWL API as dealing with structure. The parallel with relational databases is that the OWL API defines the schema and RDF the records.

The longer answer: For good explanations of the differences between OWL and RDF have a look at the answers of this SO question.

Thank you for your attention!

Semantic Web for the working ontologist which is, I think, the best intro textbook, has just had a new edition released: https://dl.acm.org/doi/book/10.1145/3382097. I recommend it.
