Error message when adding RDA vocabulary

Omeka S Modules
#1

I have tried to add some additional vocabulary to Omeka S. That works fine, except for one. Then, I receive the error message: ‘The local name cannot be empty’. What can I do to prevent this from happening?

This doesn’t work:

  • I go to my Omeka S installation > Vocabularies > Import new vocabulary
  • I add:
    • Label: RDA Manifestation
    • Namespace URI: http://rdaregistry.info/Elements/m/
    • Namespace prefix: rdam
    • Vocabulary file: the downloaded RDF/XML file from RDA Registry | Vocabularies
  • I get the error message as mentioned before.

In addition, I’ve added the URL directly and different formats, such as JSON-LD. The odd thing is that other RDA vocabularies work without any errors, like RDA Registry | Vocabularies.

Any ideas?

The “has details of generation” property has no local name. Whether this is intentional, I don’t know. It’s certainly not expected. Try this: download the XML file, remove the following lines (they’re near the end), and import the file.
