CLEAR is an Enterprise Architecture meta-model, framework and method. CLEAR stands for Comprehensive, Landscaped, Enterprise Architecture Representation.

CLEAR borrows heavily from the Zachman framework for Enterprise Architecture and the TOGAF framework specification. CLEAR is divided into four landscapes which contain artefacts. These landscapes are:

* The Environmental landscape which contains the Business Objectives or Contextual landscape

* The Business landscape which contains the Conceptual Business Architecture

* The Alignment Landscape which contains a functional architecture and services catalogue

* The Technology Landscape which contains all of the technical components necessary to deliver the business services (Software, Hardware and Infrastructure elements)

CLEAR's Services Oriented Alignment layer can be used to provide the specification for a Service-oriented architecture approach.
