Abstract
A description of models that support the combining of data from multiple sources is provided. A model supported by a data structure, as well as one supported by a full database, is described. The marine community efforts thus far have involved data structures and as such, data structure examples are given. These include the efforts of the ICES/IOC Study Group on XML (SGXML) development of the Keeley Bricks, Geography Markup Language (GML), and the efforts of the JCOMM Expert Team on Data Management Practices (ETDMP). The XML implementation of these data structures allows easy transfer, but this shifts the problem to an issue of ‘data understanding’ or semantics. Typical semantic problems include parameter code issues, units and metadata standards. Focusing on the parameter code issue, the Marine Metadata Interoperability (MMI) Project is briefly described. This project is attempting to provide interoperability between data terms by mapping and harmonizing parameter usage and parameter discovery vocabularies.
