    Corrections & Patches

  • Erroneous index entries, e.g., "SDTM v1.2", "SDTM v1.3", etc., no longer appears in the response from this API request: /mdr/search/scopes/class.
    • The hypermedia link about parent product is added back to these API endpoints. In other words, the JSON path $._links.parentProduct now contains a link:
  • /mdr/sdtm/{version}/classes
  • /mdr/sdtmig/{version}/classes
  • /mdr/sendig/{version}/classes
    • Expand

    },

    For API endpoint /mdr/root/cdash/classes/{class}/fields/{field}, the value of the type object (JSON path: $._links.self.type) now reads "Root Data Element"; originally, "Has Root Data Element". Expand
    titleExample using /mdr/root/cdash/classes/Interventions/fields/--YN

    Before, at line #6, type reads "Has Root Data Element":

    "_links": {
        "self": {
            "href": "/mdr/root/cdash/classes/Interventions/fields/--YN",

            "type": "Has Root Data Element"
        },

    }

    After, at line #6, type reads "Root Data Element":

    "_links": {
        "self": {
            "href": "/mdr/root/cdash/classes/Interventions/fields/--YN",

    Deprecations

    • Basic Auth support for API access, replaced by API key authentication.

    • definition

    • description

    • measureType

    • productGroup

    • uiHref
