# OpenRiC SHACL shapes — always-on
# ================================
# Cross-cutting shapes that apply regardless of which conformance profile
# a server claims. Load alongside any profile-scoped shape file.
#
# Shapes in this file:
#   - DateRangeShape        — structural validation of openricx:DateRange (used
#                             by Records, Agents, Activities, Rules, …)
#
# Usage (combined with a profile file):
#   pyshacl -s always-on.shacl.ttl -s core-discovery.shacl.ttl \
#           -d data.jsonld -f human
