The AV-2 Integrated Dictionary contains definitions of terms used in architecture descriptions. It is not necessarily a literal dictionary. It consists of textual definitions in the form of a glossary, a repository of architecture data, and the taxonomies and metadata (i.e., data about architecture data) of this data, including metadata for tailored products, associated with the architecture products developed. Metadata refers to architecture data types, which are possibly expressed in the form of a physical schema. In this document, architecture data types are referred to as architecture data elements.
