1. ImplementedBy SDD 1.1 Proposal

2. Current Situation SDD runtime “walks” resources in topology Resources are cataloged and cross referenced w/ profile(s) If a resource in topology is encountered that is not referenced in a profile, the runtime aborts

3. Scenario(s)/Use Case(s) SDD producer may want to type cast a resource for future management ops but use generic properties at deployment time –Example: A producer wants to deploy a database system and there is a need post- deployment to identify that resource as a database system. However, at install time the only property needed is install location

4. Proposal Allow SDD producers to type cast resources –Add an optional attribute to ResourceType –Call the attribute implementedBy and have it be an IDREF to another hosted resource in topology

5. Proposed Schema In sdd-common add the following

6. Proposed Schema

7. Example

8. Actions if approved Minor schema change Specification update to document the new attribute
