Tag language

The Information Catalog Manager tag language allows you to format your descriptive data so that you can import it into your information catalog. The tag language tells the Information Catalog Manager what to do with the descriptive data that it imports. The Information Catalog Manager also exports descriptive data into tag language files so that you can back up your information catalog or transfer data from one information catalog to another.

By formatting descriptive data with the tag language, you can move descriptive data from one information catalog to another and define Information Catalog Manager object types and objects. You can also write and use extract programs to extract descriptive data from other sources, such as a relational database catalog, that you can import to your information catalog Table 116 shows the tags in the tag language and the actions that these tags perform.
