Description of "Remove term duplicates in a SKOS/RDF-XML file" service

Files containing "skos:Concept" or "Concept" type "rdf:Description" are processed by this service.

At the level of each concept, this service operates as follows:

• All the preferred labels are kept;
• Alternative labels are compared with each other and with the preferred label of the same language:
  • if the same term appears several times as an alternative label of the same language, only one occurrence is kept;
  • if the same term appears both as an alternative label and the preferred label of the same language, only the preferred label is kept.
• Hidden labels are compared with each other, with the preferred label, and with alternative labels of the same language:
  • if the same term appears several times as a hidden label of the same language, only one occurrence is kept;
  • if the same term appears both as a hidden label and the preferred label of the same language, only the preferred label is kept;
  • if the same term appears both as a hidden label and an alternative label of the same language, only the alternative label is kept.

At the end of this process, check the file again using the Controlling a SKOS/RDF-XML file at the concept level service to ensure that there are no more duplicates.
