Data Catalog contents

The Data Catalog contains noun metadata information organized in libraries. A library can contain one or more nouns. Libraries contain standard objects, which can either be global or application-specific. You can use the available noun metadata from all libraries in ION Desk models.

Custom objects can be of type BOD, also referred to as "custom nouns", or of type ANY, DSV, or JSON.

At each library level, each tenant level, and each noun level, a patch number is maintained. Only the latest noun metadata for both standard and custom nouns is stored in the Data Catalog.

For each noun, custom or standard, this information is stored:

  • Noun Name
  • Noun XSD - the XML schema definition for this noun, flattened
  • Other metadata, such as the patch number (a kind of version number), the list of XPaths to key fields in the noun, the list of verbs supported by this noun, and the relationships between this noun and other nouns.

For custom objects of type ANY, only the object name is stored.

For custom objects of type JSON, the JSON schema definition for each object name is stored.

For custom objects of type DSV, the DSV schema definition for each object name is stored.
