Mission Requirements


This specification is designed to fulfill a number of requirements in support of the transformational efforts of the Intelligence Community (IC). These requirements include:

  • The need for a shared common manifest to securely encapsulate and transport things (e.g., patches) from one network to another.
  • The need to normalize metadata to facilitate communication between groups (e.g., government, commercial industry) with regards to the transport of things (e.g., patches).
