# =====================================================================
# DRAFT — upstream Energie-Atlas field-name namespace (the SOURCE layer).
#
# Mirrors linked-mastr's mastr: namespace: every upstream feature
# attribute is mapped 1:1 to a predicate here under its ORIGINAL name,
# so nothing is lost in the domain mapping. The DOMAIN layer (cleaned,
# typed) lives in the sibling namespace vocab: (<vocab#…>).
#
# PLACEHOLDER: the real attribute names are NOT YET CONFIRMED. Do not add
# terms here speculatively — populate this file from the actual feature
# schema once the access method (WFS DescribeFeatureType / Atom GML /
# API) is pinned down. See TODO(mapping) and the plan referenced in
# README.md.
