A common framework for extending the system and software life cycle processes of IEEE Std 12207(TM)-2008 to include the systematic practice of reuse is provided. The processes, activities, and tasks to be applied during each life cycle process to enable a system and/or product to be constructed from reusable assets are specified. The processes, activities, and tasks to enable the identification, construction, maintenance, and management of assets supplied are also specified.

ISO/IEC/IEEE International Standard - Information technology -- Modeling Languages -- Part 2: Syntax and Semantics for IDEF1X97 (IDEFobject)
IDEF1X97 consists of two conceptual modeling languages. The key-style language supports data/information modeling and is downward compatible with the US government's 1993 standard, FIPS PUB 184. The identity-style language is based on the object model with declarative rules and constraints. IDEF1X97 identity style includes constructs for the distinct but related components of object abstraction: interface, requests, and realization; utilizes graphics to state the interface; and defines a declarative, directly executable Rule and Constraint Language for requests and realizations. IDEF1X97 conceptual modeling supports implementation by relational databases, extended relational databases, object databases, and object programming languages. IDEF1X97 is formally defined in terms of first order logic. A procedure is given whereby any valid IDEF1X97 model can be transformed into an equivalent theory in first order logic. That procedure is then applied to a meta model of IDEF1X97 to define the valid set of IDEF1X97 models.
