# Title: The DALICC vocabulary (https://dalicc.net/ns#)
# Author: DALICC
# Source: https://github.com/dalicc/dalicc_production
# Licensed under: Attribution 4.0 International (CC BY 4.0)
#
# This file is the successor of the DALICC vocabulary documentation that was published
# at https://dalicc.github.io/ (served as docs.dalicc.net) and last updated 2022-03-15.
# It reconciles two sources:
#
#   1. the 2022 documentation, whose lawyer-written definitions are reproduced VERBATIM
#      as `rdfs:comment` and carry `dct:source <https://dalicc.github.io/>`;
#   2. the terms that actually occur in the DALICC data (licensedata/licenses/*.ttl and
#      licensedata/dependencygraph/dg_default.ttl), whose plain-language explanations come
#      from the lawyer-reviewed help texts of the original DALICC license composer and are
#      carried as `skos:definition`.
#
# Terms documented in 2022 that no license in the current library uses are kept and marked
# with `skos:note "Defined in the 2022 documentation; not used by any license in the current
# library."` -- they are part of the published namespace and must keep dereferencing.
#
# The file is loaded into the named graph <https://dalicc.net/ns> (see dalicc-ns.ttl.graph).
#
# NOTE ON THE NAMESPACE SCHEME: the authoritative namespace is `https://dalicc.net/ns#`.
# The 2022 documentation and historical Virtuoso dumps use the plain-HTTP form
# `http://dalicc.net/ns#`; it is recorded as `owl:priorVersion` and must not be used in new
# data. See docs/DATA.md.
#
# NOTE ON THE SPELLING `royalityFree`: the 2022 documentation misspells "royalty". The
# canonical term is `dalicc:royaltyFree`; `dalicc:royalityFree` is kept as a deprecated alias
# (`owl:deprecated true`, `dct:isReplacedBy`) because external data may already use that IRI.
