Who develops Morph-KGC?

Morph-KGC was created in the Ontology Engineering Group at Universidad Politécnica de Madrid by Julián Arenas-Guerrero along with other contributors.

How can I learn R2RML, RML or RML-star?

The best starting point is the R2RML Recommendation. After that, you can continue with the RML or RML-star specifications.

The best place to get the answer is at Discussions for RML questions.

I installed Morph-KGC but I get an error saying some dependency is missing

To use relational databases and some data files it is required to install additional libraries. You can see which one you need to install in Advanced Setup.

How do I submit a bug report?

Please, open an issue with a clear description of the bug. We will try to solve it as soon as possible.

I have a suggestion to improve the documentation

Please, open an issue providing a description of what documentation you believe needs to be fixed/improved and your suggestion. You can also contribute with a pull request to the GitHub repository.

Can I use Morph-KGC in a commercial project?

Yes! Morph-KGC is distributed under the Apache License 2.0 which allows commercial use, modification, distribution, patent use and private use. Of course, we will appreciate it if you tell us that you are using Morph-KGC and can give us some details on how it is being used (as much as you can given confidentiality constraints). This would allow creating a database of projects where Morph-KGC is being used that could help us to request additional funding in the future, if needed.

I need commercial support
