Methodological lineage

The typed-edge schema (cites, verweist_iVm, planned: amends,
transposes, superseded_by, delegates_to_land,
delegates_to_kommune, concretizes, implements_via_vo) follows
Coupette, Beckedorf, Hartung, Bommarito and Katz,
"Measuring Law Over Time", Frontiers in Physics 9 (2021),
https://doi.org/10.3389/fphy.2021.658463 — the only published
graph schema covering the entire German Bundesrecht corpus.

The cites-citation regex patterns are adapted from
de-jure-regex-style heuristics for German legal-citation
syntax (§ N Gesetz, Art. N Gesetz, i.V.m. § N).
