Abstract:
Complex systems often are built on the basis of services that are composed in a loosely coupled way. Data exchange between system components takes place in an external format that conforms to a system-wide agreed schema. Content Management Systems (CMSs) are one example of a class of systems that do not process data with fixed semantics, but that manage and publish meaningful content. Such systems require a consistent interpretation of data as content on both ends in order to preserve meaning. We argue that such a consistent interpretation requires mappings between content models underlying CMSs and data models used for communication, and that these mappings, therefore, must be shared by all components of the system. In order to justify this claim, we compare the expressiveness of plain data formats with that of content modeling languages, and we study mappings between them. In this paper, we use JSON and JSON Schema as a typical examples of external data representations. We discuss content models using the example of the Minimalistic Meta Modeling Language (M³L). Our initial research shows that schemas for data exchange should be tightly linked to content models in order to not only represent content as data, but also to allow for consistent interpretations of content.
