2: Enhanced Interoperability with Domain Data Modeling

Disparately developed systems have data items de昀椀ned locally during development, providing a local understanding of the
data item semantics. This is also true within system programs where semantics are de昀椀ned at a functional product level. While
the data requirements in these programs are documented, there is ambiguity that results in inef昀椀cient integration and potential
errors during interoperation. Open Data Models provide a standard and formal way to capture the data entities, their semantic
context, and relationships in a tool-based representation that can be built and managed by stakeholders across an enterprise.
The model allows the data requirements of any interface to be understood as a separate design requirement, independent of
other interface considerations such as syntax, behavior, protocol, or bearer design choices, and captures a machine-readable
product where semantic ambiguity is removed from the dataset.
The modeled dataset and interface data speci昀椀cations bene昀椀t the management of data documentation across the enterprise,
standardize semantic de昀椀nition in software products for more ef昀椀cient integration, and introduce inherent compatibility among
interoperating systems.
This data model approach is a key element in enabling 昀氀exibility and collaboration within and among systems to provide a
coherent and collectively advanced military capability.
