We have a DASFactory [2] that is responsible to instantiate a concrete DAS implementation based on the DAS Interface. In Tuscany, we currently have a DAS RDB implementation, and a experimental LDAP implementation, and in the past we have had a Fluid DAS (based on OpenJPA). In your case, to plug a custom DAS, you will need to provide a implementation of DASFactory and DAS interfaces at minimum, Also, Overall Tuscany DAS documentation is available at [3].
