An experimental Linked Data wrapper over geolocated open data published by the German Bundesnetzagentur (BNetzA). Unlike a dataset-specific wrapper, this one is organisation-centric: it currently covers two independent sub-datasets and is designed to grow.
The public register of EV charging points, updated monthly
(CC BY 4.0,
attribution "Bundesnetzagentur.de"). Station location (WGS84, as
geo:asWKT), operator, status, and up to 6 connectors per
station (type, power, EVSE-ID).
vocab:nennleistungKW 350,
the fastest DC charging currently deployed in Germany.vocab:hasLadepunkt
slots filled and mixed connector types (CCS + AC) — the full
per-connector nesting the model supports.vocab:status "In Wartung" (under
maintenance) — the register tracks operational state, not just
"exists".
Bundesbedarfsplangesetz / Energieleitungsausbaugesetz transmission-grid
expansion project geometries — points and line corridors — from BNetzA's
public netzausbau.de ArcGIS FeatureServers. No licence exists
upstream for this sub-dataset (checked netzausbau.de's Impressum,
its linked "Merkblatt Geodaten" PDF — which turns out to cover an
unrelated topic — and the FeatureServer's own item metadata; all empty of
licensing terms) — served documents carry dcterms:license as
a literal disclaimer saying so, not a URI.
linked-mastr entries../vorhaben/enlag/{id},
./vorhaben/anbindungsleitung/{id}
BNetzA's own power-plant list, 2,193 entries
(Datenlizenz Deutschland –
Namensnennung – Version 4.0, confirmed on BNetzA's site-wide
Impressum, not the Kraftwerksliste page itself). No
coordinates — see the note above about why linked-mastr
covers per-plant location instead.
EinheitMastrNummer,
lowercased) — the SAME real-world unit as the
./ladesaeule/ examples' neighbourhood, this time as a
registered power plant rather than a charging station.Kleinanlagen_aggregiert row — all <10 MW onshore
wind plants in Thuringia, summed (1,910 MW total) — id is a
SYNTHETIC slug, not an upstream identifier.
BNetzA's own forecast of planned generation-capacity changes 2026–2029.
Same licence as Kraftwerksliste. Two flat documents, not
per-row URIs — 36 + 40 rows is small enough that each table is
ONE document, every row a blank node nested under it (the same
connector-nesting shape vocab:hasLadepunkt uses above), not
a per-record dump.
Record IRIs follow the hash-URI pattern ./{dir}/{id}#it; the
fragment distinguishes the thing (#it) from the
document describing it (linked via foaf:primaryTopic;
httpRange-14).
The document is content-negotiated — suffix wins over Accept:
{.ttl, .nt, .rdf, .jsonld, .html} map to Turtle, N-Triples,
RDF/XML, JSON-LD 1.1 and HTML; no suffix lets the Accept header choose
(HTML default).
A client finds every route from ./index: it lists the
collections (ladesaeule/, vorhaben/,
kraftwerk/) and the two flat documents, and each collection
pages through its members and describes, as
Hydra URI templates, how to
look one up.
Both sub-datasets carry GeoSPARQL
geometry (geo:asWKT, CRS84 lon/lat WKT literals) — points for
charging stations and the netzausbau.de waypoints, (multi)line strings for
the project corridors.
linked-mastr
Neither sub-dataset here links to linked-mastr's
Marktstammdatenregister wrapper directly (identifiers stay literals, not
minted owl:sameAs links — a wrong cross-link is worse than a
missing one), but the same real-world entities show up in both, findable
by name. ./vorhaben/bbplg/28#it above (thread it through
both wrappers) names 50Hertz Transmission GmbH as its
vocab:vorhabentraeger — the same company appears in
linked-mastr in two different Marktrollen:
For a genuinely co-located example rather than a shared company name,
linked-mastr's
within?bbox=
spatial query over the Berlin area finds real MaStR generation units
(e.g. a battery storage installation, "Batteriespeicher") sitting inside
the same bounding region vorhaben/bbplg/28's own line
corridor runs through — a looser, HONEST "same grid region" link, not a
claim that any single point coincides exactly.
The wrapper-coined RDFS/OWL vocabulary is at
./vocab (vocab:Ladesaeule,
vocab:Ladepunkt, vocab:Vorhaben, …).
The dataset description and the global software agent are at
./index.
