The ontologics package provides tools to build and work
with an ontology of linked (open) data
in a tidy workflow. In the current workflow the data are only available
at the three star level in comma-separated values tables, or actually an
R-optimized *.rds file of such a table.
The type of ontology is inspired by the FAO caliper platform and makes use of the Simple Knowledge Organisation System (SKOS).
An ontology is any data structure that stores concept of any knowledge field in a linked way. It is typically built on a set of standardized/harmonized terms that have a clear definition and potentially some attributes. According to the SKOS, concepts can have semantic relations or can be mapped to one another. Semantic relations describe how harmonized concepts relate to one another and mappings describe which concepts from different vocabularies should be linked to one another.
The key tasks, beyond creating a formally valid ontology, is extracting concepts and their relation to other concepts and mapping new concepts to an existing ontology to capture and set potentially deviating definitions into relation.
