The directory docs contains all the files related to the ontology, its versions in time, and the related documentations. In particular, it includes:
current directory, where the files of the current version of the ontology are stored;yyyy-mm-dd version directory for each of the versions of the ontology developed.The current directory contains five files, named after the lowercase ontology acronym, with the following extensions specifying different formats: .xml (RDF/XML), .ttl (Turtle), .nt (Ntriple), .jsonld (JSON-LD), .html (HTML, i.e. the human readable documentation of the ontology). All the images used in the documentation should additionally be included in this directory.
The version directories (i.e. yyyy-mm-dd) contains the same kinds of files as those included in the current directory, but specific for that particular version.
