(https://uacloudlibrary.opcfoundation.org/graphql?query={nodeSets(keywords%3A"http%3A%2F%2Fopcfoundation.org%2FUA%2FAMLLibs%2F")%20{totalCount%20nodes{modelUri%20identifier}}})

query MyQuery {
  nodeSets(keywords: "http://opcfoundation.org/UA/AMLLibs/") {
    totalCount
    nodes {
      modelUri
      validationStatus
      validationStatusInfo
      identifier
      requiredModels {
        modelUri
        publicationDate
