  • Method Details

    • createGlossary

      public SubjectAreaOMASAPIResponse<Glossary> createGlossary(String userId, Glossary suppliedGlossary)
      Create a Glossary. There are specializations of glossaries that can also be created using this operation. To create a specialization, you should specify a nodeType other than Glossary in the supplied glossary.

      Glossaries with the same name can be confusing. Best practise is to createGlossaries that have unique names. This Create call does not police that glossary names are unique. So it is possible to create Glossaries with the same name as each other.

      Valid nodeTypes for this request are:

      • Taxonomy to create a Taxonomy
      • CanonicalGlossary to create a canonical glossary
      • TaxonomyAndCanonicalGlossary to create a glossary that is both a taxonomy and a canonical glossary
      • Glossary to create a glossary that is not a taxonomy or a canonical glossary
      Parameters:
      userId - unique identifier for requesting user, under which the request is performed
      suppliedGlossary - Glossary to create
      Returns:
      response, when successful contains the created glossary. when not successful the following Exception responses can occur
      • UserNotAuthorizedException the requesting user is not authorized to issue this request.
