For emulation and other preservation actions, metadata is needed to describe the technical environment (operating system, related software libraries, hardware etc.) in which a given file or item of software can be rendered. This paper delineates an enhanced entity attribute relationship model suitable as a basis for a database (relational, object-relational or object-oriented), or for a RDF ontology. This core data model covers the X86, Apple II and Commodore 64 (C64) hardware architectures, as well as games consoles. The model is currently instantiated as a MySQL database with accompanying API, plus a PHP-based browsing system. Data population, and user evaluation are also discussed. The model is extensible over the long term and is compatible with OAIS and PREMIS version 2.
