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.
