These relationships are not a mandatory part of the <span>Standard</span> package, as you can now define better custom relationships with appropriate names.</li> <li>The glossary terms had two workflow related properties in previous versions. Status has been renamed Workflow State with the same values (Candidate, Draft, Under Review, Pending Approval, Approved, Published, and Deprecated) and State (Deprecated, New, and Published) is replaced with Workflow Published (True/False) and Workflow Deprecation Requested (True/False).</li> <li>The Abbreviation attributes are migrated to a new <span>Has Acronym</span> relationship to a new Acronym object. The Alternative Abbreviation attributes are not migrated.</li> <li>The categories and terms were used to implement naming standards, which are now implemented by a <span>Naming Standards</span> model. This model contains Naming Standard objects including Naming objects. <p>When enabling the naming standards, you now have to select which Naming Standard object you want to use instead of a glossary category. The <span>Migrate Glossaries to Metamodel</span> operation also migrates any categories and terms used for naming standards into new objects of the <span>Naming Standards</span> model.</p> </li> </ul> | <ul>Verfügbar in:<li>Cloud Data Catalog Advanced Edition</li><li>Cloud Data Catalog Advanced Plus Edition</li><li>Cloud Data Catalog Standard Edition</li><li>Data Catalog Advanced Edition</li><li>Data Catalog Advanced Plus Edition</li><li>Data Catalog Standard Edition</li></ul><br><br>Alle Lizenzen von Talend Data Catalog |
