Open Access padlockePrints

The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

A Categorical Formalism for Interoperability based on the Information Resource Dictionary Standard (IRDS)

Abstract

Interoperability is considered in the context of the ISO standards for the Information Resource Dictionary System (IRDS) which provide a complete definition of an information system from real-world abstractions through constructs employed for data and function descriptions to the physical data values held on disk. The IRDS gives a four-level architecture which is considered 1) informally in terms of an interpretation of the levels and the level-pairs between them, 2) in terms of mappings between the levels and 3) formally in terms of a composition of functors and adjoints across the various levels. Two examples are given of the application of IRDS in a categorical context, one comparing the mappings from abstractions to values in relational and object-based systems, the other comparing the mappings from the concept of time to date representations in a number of different approaches. Such comparisons provide a route for interoperability between heterogeneous systems.
