Description of 21/30416015 DC 2021This document defines an ontology for a fine-grained description of the expressive power of CQLs in terms of search needs. The ontology consists of three interrelated taxonomies of concepts: a) the CQLF Metamodel (a formalization of CQLF-1), b) the Expressive Power taxonomy, which describes different facets of the expressive power of CQLs, and c) a taxonomy of CQLs. The normative parts of this document comprise a) the taxonomy of the CQLF Metamodel, b) the Functionality layer of the Expressive Power taxonomy, c) the structure of the layers of the Expressive Power taxonomy and the relationships between them, in the form of subsumption assertions, as well as d) the formalization of the linkage between the CQL taxonomy and the Expressive Power taxonomy, in the form of positive and negative conformance statements. This document does not provide a normative listing of the middle and bottom layer of the Expressive Power taxonomy (called Frames and Use Cases, respectively). An exhaustive inventory of the concepts at these two layers is not possible due to the fact that existing CQLs differ widely in the complexity of the supported combinations of Functionalities and that new CQLs can be created offering additional combinations or subtypes of Functionalities. Frames and Use Cases are expected to be filled in through a moderated community process, driven by CQL developers as well as end users. An informative annex to this document contains a sample of Frames and Use Cases together with conformance statements linking them with the CQP [5] and ANNIS [7] query languages.
