Interior architecture data gets analyzed against a set of five Interior reference models. These models are the Interior adaptation of the OMB reference models described on the Federal Enterprise Architecture Program Management Office (FEAPMO 
) site.
The five models picture five aspects of architecture, in much the same way the plumbing diagram and electrical diagram show two aspects of the architecture of a house. The model helps architects concentrate on one aspect at a time, while understanding that all these parts have to fit together in the final structure.

Developing a Common Language for the Interior
The IEA program has extended all the FEA Reference models to Interior-specific areas. The models include:
- PRM - (Performance Reference Model) Linking the DOI Strategic Plan to the OMB FEA PRM as well as DOI Activity Based Costing work activities
- BRM - (Business Reference Model) Linking the Activity Based Costing work activities to the FEA BRM as well as extending them for specific lines of business: Law Enforcement, Financial Management (based on FBMS), Recreation, and Wildland Fire Management
- SRM - (Service Reference Model) Adding domain principles, best practices, but no new extensions to the FEA SRM
- TRM - (Technical Reference Model) Added standard and technical Service/Product Specifications used at Interior to the FEA TRM
- DRM - (Data Reference Model) For specific lines of business, developed DRM based on principles of the FEA DRM (NOTE: Currently it is saved in a separate work area (separate encyclopedia)
