Building Semantic Technologies Based on Relational-Applicative Foundations ⁎

We present a formal framework for semantic data representation and processing. Our approach is based on first merging relational and applicative approaches and then augmenting the merge with means allowing to view and manipulate data objects from semantic perspective. Our results at this point are primarily applicable in information systems development, where an engine for object description is called for. Which is the case when, for example, the exact conceptual scheme of the subject domain is unknown, may vary over time or/and consists of too big a number of entities and relationships. The framework may also be of interest from the perspective of implementing semantic features in relational database managements systems.
