•  Provision of a main document for DDI 4 providing a common understanding of the goals of DDI 4 based on current understanding. The audience for the document includes people involved with the Moving Forward Project, DDI Alliance members, and the public. This should be organized in a way that appropriate sections can be used as part of the high level Class Library documentation as as a common section for the high level document for each Functional View.

•  Review of package integration including where packages touch, how information passes between packages, how overview or strictly descriptive classes relate to more detailed/machine-actionable classes, and how this is expressed in Functional Views.

•  Perform a coverage and gap review between DDI 4 and DDI-Lifecycle (DDI 3), and DDI 4 and GSIM. Determine how this affects the on-going development of DDI 4 and DDI-Lifecycle (DDI 3)
