The workflow components are not coupled in anyway to identity components. If there is anything which is blocking you from achieving what you need then we will like to know about it so that we can fix our design. > IMO other products should be able to use their own workflow info > preservation mechanism. > Ex: To store in the registry > To store in a database > Say in ES, we want to provide workflow support for asset creation. Storing > asset level info in Identity database doesn't make sense. > Don't think of it as Identity database. Think of it as a database coming from another feature repository. It can be any product like IS. If the same workflow component was developed by APIM then it would be AM_ tables. Apart from the naming convention the functionality is generic and extensible. The table naming convention comes from which product team develops it, thats all. Using Identity database in ES is not wrong. If you are installing IS feature you have to install the database scripts also. I know previously APIM did the same mistake of copying the identity tables into apim scripts and not executing identity scripts. I know how much duplication it made and how much of problems we ran into. I am -1 on that. If you have a strong reason to move away from database, and use registry then we need to think about making the data access layer extensible, which is open for discussion. P.S. I know we haven't sent a mail to architecture regarding the workflow component design. Will do soon.
