Here are the major types of integration meta data, as defined by Gartner Inc. This is just a starting point, however. Many organizations will opt to keep only a subset of these meta data types in a centralized repository.
Communications content
• What is in the data being sent (the schema of the transmitted payload, including file schema, ORB calling parameters, etc.).
• Syntax information, including tags, field lengths, data types, etc.
• Validation rules for range checks, cross-field validation, etc.
• Transformation rules to map the transmitted object to a different schema.
• Housekeeping information covering message structure, size, etc.
Touchpoint identities
• The identity of specific apps and their entry and exit points, files or databases; where the information is going to and from.
• Contact information for business units/people responsible for maintaining the data sources, destinations and any necessary adapters.
Interaction process and business implications
• Routing information -- rules for content-based routing, etc.
• Communication model, including store-and-forward, publish and subscribe, etc.
• Technology for each source and destination of data -- transport mechanism and communication protocol.
