UAF is the evolution though not substitution of ISO/IEC 19513:2017 Information technology, Object Management Group Unified Profile for DoDAF and MODAF (UPDM), 2.1.1.
The primary goal of UAF is to produce robust Architectural Descriptions in alignment with ISO/IEC/IEEE 42010:2011, Systems and software engineering -- Architecture description. UAF provides a specification language that is readily understandable not only by the community of enterprise architects, architects of information technology systems or systems engineers but also by a wide- range of end users including executives and enterprise management that sponsor such systems, program managers that oversee their development, developers of supporting hardware and software (design, implementation, and testing), subject matter experts, and end users. UAF bridges the gap from setting of requirements to theoreticians to visualization for practitioners.
The specification is split into two parts represented by two separate documents:
Part 1: Domain Metamodel (DMM)
Part 2: Unified Architecture Framework Profile (UAFP)
Part 1 provides a formal domain meta model (DMM) organized in a number of View Specifications. View Specifications are arranged in a two-dimensional grid. The grid is organized into rows and columns, where rows are Domains and columns are Model Kinds. The Domains include: Metadata, Strategic, Operational, Services, Personnel, Resources, Security, Project, Standards, Actual Resources, Dictionary, Summary and overview, and Requirements. UAF also supports User-defined Domains and Model Kinds. The intersection of a row and column is called a View Specification. Every View Specification has a number of elements required to construct the View. The primary elements in UAF are: Capabilities, Operational Performers and Operational Activities, Resources (including Performers [Persons, Organizations, and Systems], Natural Resources, and Information/Data), Functions, Constraints/Rules, Service Specifications, Projects, and Standards.
The UAF DMM is based on the IDEAS Ontology. Everything in this ontology has four dimensions (temporal and spatial), subtypes, and measures (OMG C4i/2014-05-02, DoDAF 2, Overview and Concepts).
Part 2 of the specification, defines a number of practical Views and elements that are mapped to the Domain Metamodel described in Part 1. UAFP specifies UAF DMM implementation in Unified Modeling Language (UML) (ISO/IEC 19505-1:2012, Information technology -- Object Management Group Unified Modeling Language (OMG UML) -- Part 1: Infrastructure; and ISO/IEC 19505-2:2012, Information technology -- Object Management Group Unified Modeling Language (OMG UML) -- Part 2: Superstructure) and Systems Modeling Language (SysML) (ISO/IEC 19514:2017 Information technology ? Object management group systems modeling language (OMG SysML)) modeling languages. It defines UML extensions (so called stereotypes) to support a UAF DMM. It is also dependent on a SysML profile, which is another extension to UML. The purpose of this dependency is to inherit SysML graphical notation, and engineering analysis techniques applicable to SysML (e.g., parametric analysis).
Vendors have provided automated software tools that facilitate defining, deriving, and populating the domain meta model in the context of a specific project and communication of results in generally accepted graphical format to the various users. Conformant tools exchange data with OMG XMI (ISO/IEC 19509:2014, Information technology -- Object Management Group XML Metadata Interchange [XMI]).
Along with Part 1 and Part 2 of the UAF specification there are two normative machine readable files (in XMI format) included in the submission package:
