TOTEM: Trusted Online Technical Environment Metadata - A Long-Term Solution for a Relational Database / RDF Ontologies
Janet Delve Antonio Ciuffreda Leo Konstantelos
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.
