Thesaurus Field

Introduction

A ThesaurusField is a complex field which describes a single concept from a thesaurus. It contains as children both the URI and a label for each language configured.

ThesaurusUriField contains the URI of a concept
ThesaurusLabelField contains the breadcrumb of a label in a particular language

Example

The field Metadata 21.3 | LimitedCategories is an example containing a list of thesaurus fields.

"LimitedCategories": {
   "Category": [
      {
          "En": "architecture > building",
          "Nl": "architectuur > gebouw",
          "Uri": "https://mh-dev.mediahaven.com/thesaurus/conceptschemes/mhdevLimitedCategoriesCategory/c/27"
      },
      {
          "En": "types > textile",
          "Nl": "types > textiel",
          "Uri": "https://mh-dev.mediahaven.com/thesaurus/conceptschemes/mhdevLimitedCategoriesCategory/c/50"
      }
  ]
}

Enhancement

When updating metadata with the thesaurus field containing only a single label, the system automatically attempts to find the linked concept and fill out both the URI and other labels. If the concept is not found an error is thrown.

For example the metadata below is enough to automatically enhance it to the metadata above.

"LimitedCategories": {
  "Category": [
    { "En": "building" },
    { "Nl": "textiel"  }
  ]
}

Global

When the thesaurus URI field is marked as global, the global search will also match the object based on the preferred and non-preferred labels from all languages, including all ancestors.
