Besides organizing your views and web services in categories, the Data Catalog allows you to assign tags to your resources. A tag is a label you can use to describe an element and to retrieve it later when browsing or searching.
To start browsing your views and web services by tags, go to Browse > Tag. The sidebar shows the list of tags available in the Data Catalog. Click a tag and access to its details.
You will find all the elements that have been assigned with the selected tag in the Views and Web services tabs. The Summary tab gives you a description for the tag.
If you have the proper permissions, you will be able to edit this information. Use the icon next to the name or description to update its value. Click the Assign tag button and access to a new page where you can change the set of views and web services that are described by the tag.
When you are browsing by tags, the Data Catalog shows you the elements stored in its metadata. If there were changes in Virtual DataPort since the last time the Data Catalog was synchronized, these changes will not be reflected.
