DS-015 MVP progress tracking

At the call today we were discussing my recent changeset to the DSDL repository and its key architectural decisions. A solid workflow requires that all participants of the DS-015 workgroup are up to date on the high-level technical requirements and on the best applicable practices. It may be sensible to split the workgroup into two levels: one defines the high-level business requirements, the other develops the appropriate technical solutions.
