For the time being, the BLL Ontology includes the concepts from the thesaurus branches Syntax, Morphology, Lexicology and Phonology as well as some additions originating from the branches Graphemics and Semantics.
2020/01/30 Circa 2,200 language identifiers from the BLL Thesaurus were integrated in the BLL Ontology. The new ontology branch (Language-related term) is modeled in compliance with the established methodology, i.e. language identifiers are defined as ontological classes and hierarchical relations are modeled by means of subClassOf relations (e.g. a class German with subclasses High German and Low German).
The hierarchical structure reflects established conventions and traditions as well as the specificity of the BLL Thesaurus. The language classification is not based exclusively on genealogical principles: The family tree model was adopted where appropriate, but the classification also includes groupings based on geographic location (e.g. Australian languages), or modality (e.g. Sign languages) (Dimitrova et al. 2018).
Furthermore, some design decisions were reconsidered starting with the application of complex class expressions (intersection or union). In the initial version of the ontology, complex classes were used with SubClassOf and EquivalentClasses axioms. For practical reasons, this modeling principle was changed to allow complex classes only with EquivalentClasses axioms.
Consequently, all concepts initially modeled by means of complex class expressions were revised. In the general case, a concept formerly defined as a subclass of a complex class was remodeled as a polyhierarchy (a node with two parent nodes). All changes are documented as part of the class annotations by means of owl:versionInfo.
