Each Data Manager typically has "static" properties (or non-instance data) that can be kept in the Broker.

Need to add additional static data to the COSMOS Broker..


The static properties of a Data Manager are:

  1. The Dialect, represented as a namespace (for example, SML).
  2. The SOAP version, represented as a namespace.
  3. The MdrId, a unique identifier of the MDR (this value only applies to MDRs).
  4. The Security level required by the Data Manager, also represented as a namespace value. Currently we only support basic security.

Note that all of the above properties are optional.

Relevant Use Cases

Use Case: Configure an MDR

Query for a list of MDRs and their Meta Data

Design considerations

This change impacts:

  1. the Broker registration interface must support these new values
  2. the CLI application
  3. the COSMOS UI
    • display the new properties in the properties view
    • use the security information to determine whether to prompt the user for credentials
