        "produces": [ "Sql[pao_db]" ],
        "consumes": [],
        "node": "agent1" },
      "Web[pao_w1]": {

        "node": "agent2" },
      "Web[pao_w2]": {

}

The response contains the name of the environment in the environment key, and a list of applications in that environment in the applications hash. The type/title of each application is used as the key in that hash, and the entry for that application consists of a hash of the components, again keyed by the type and title of the component.

For each component, the catalog indicates what service resources the component produces and consumes, as well as the node to which that component is mapped.

Planned response change

The response format is likely to change in the following way:

  • the applications hash will become an array of hashes, where each hash represents an application with separate keys for type and title, and for the components of the application
  • the components of an application will similarly be represented as an array of hashes, similar to the format used today, but with the addition of the component’s type and title inside the hash
