Fetch one EU legal act from EUR-Lex by CELEX number and return its FORMEX-4 XML content-addressed (SHA-256), so a flow's audit trail pins the exact Gesetzesstand it processed. - CELLAR content negotiation (application/xml;type=fmx4) on publications.europa.eu; 303 multiple-choice item selection - host-pinned redirect handling (max 3 hops), 64 MB body cap - consolidated CELEX (0...-YYYYMMDD) yields consolidation_date - net permission pinned to publications.europa.eu; no auth - 10 unit tests (no network), wasm32-wasip2 build green Signed-off-by: flemming-it <sf@flemming.it>

||||||
|
4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions:

|
||||||
|
|
||||||
|
You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License.
|
||||||
|

In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for damages, including any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or out of the use or inability to use the Work (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses), even if such Contributor has been advised of the possibility of such damages.
|
||||||
|
|
||||||
|
9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License.

EU-Rechtsakte per CELEX-Nummer von EUR-Lex holen
|
||||||
|
|
||||||
|
## Was es tut
|
||||||
|
|
||||||
|
Löst eine CELEX-Nummer auf (z. B. `32016R0679` für die DSGVO oder
|
||||||
|
konsolidiert `02016R0679-20160504`), ruft den Rechtsakt vom
|
||||||
|
öffentlichen EUR-Lex-Endpunkt ab und liefert das FORMEX-4-XML plus
|
||||||
|
einen Metadaten-Datensatz. Die geholten Bytes sind inhaltsadressiert
|
||||||
|
(SHA-256) — das Prüfprotokoll des Flows hält damit den exakten
|
||||||
|
Gesetzesstand fest; ein späterer Abruf „derselben" CELEX-Nummer, den
|
||||||
|
EUR-Lex anders rendert, wird sichtbar statt still.
|
||||||
|
|
||||||
|
Ausschließlich öffentliche EUR-Lex-Daten; die Netzwerk-Berechtigung
|
||||||
|
ist auf `publications.europa.eu` festgelegt (CELLAR, der Speicher des
|
||||||
|
EU-Amts für Veröffentlichungen hinter EUR-Lex).
|
||||||
|
|
||||||
|
## Verwendung
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
steps:
|
||||||
|
- id: fetch
|
||||||
|
use: source.eu-recht@^0
|
||||||
|
with:
|
||||||
|
celex: "32016R0679"
|
||||||
|
language: "DE" # optional, Standard DE
|
||||||
|
- id: normalize
|
||||||
|
use: text.akoma-normalize@^0 # ab 0.2 mit FORMEX-4-Adapter
|
||||||
|
with:
|
||||||
|
content: "{{ fetch.formex }}"
|
||||||
|
mime: "application/x-formex+xml"
|
||||||
|
```
|
||||||
|
|
||||||
|
Ausgaben: `formex` (Bytes, `application/xml`) und `meta` (JSON mit
|
||||||
|
`celex`, `language`, `url`, `source_sha256`, `byte_len` sowie
|
||||||
|
`consolidation_date` bei konsolidierten CELEX-Nummern).

Fetch EU legal acts from EUR-Lex by CELEX number
|
||||||
|
|
||||||
|
## What it does
|
||||||
|
|
||||||
|
Resolves a CELEX identifier (e.g. `32016R0679` for the GDPR, or the
|
||||||
|
consolidated form `02016R0679-20160504`) against the public EUR-Lex
|
||||||
|
CELLAR endpoint and returns the act's FORMEX-4 XML plus a
|
||||||
|
metadata record. The fetched bytes are content-addressed (SHA-256),
|
||||||
|
so the flow's audit trail pins the exact Gesetzesstand that was
|
||||||
|
processed — a later re-fetch of "the same" CELEX that renders
|
||||||
|
differently upstream becomes visible instead of silent.
|
||||||
|
|
||||||
|
Public EUR-Lex data only; network permission is pinned to
|
||||||
|
`publications.europa.eu` (CELLAR, the EU Publications Office store
|
||||||
|
behind EUR-Lex).
|
||||||
|
|
||||||
|
## How to use
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
steps:
|
||||||
|
- id: fetch
|
||||||
|
use: source.eu-recht@^0
|
||||||
|
with:
|
||||||
|
celex: "32016R0679"
|
||||||
|
language: "DE" # optional, default DE
|
||||||
|
- id: normalize
|
||||||
|
use: text.akoma-normalize@^0 # 0.2+ understands FORMEX-4
|
||||||
|
with:
|
||||||
|
content: "{{ fetch.formex }}"
|
||||||
|
mime: "application/x-formex+xml"
|
||||||
|
```
|
||||||
|
|
||||||
|
Outputs: `formex` (bytes, `application/xml`) and `meta` (JSON with
|
||||||
|
`celex`, `language`, `url`, `source_sha256`, `byte_len`, and
|
||||||
|
`consolidation_date` for consolidated CELEX numbers).

Methodological lineage
|
||||||
|
|
||||||
|
The output schema is aligned with Akoma Ntoso 1.0 (OASIS
|
||||||
|
LegalDocML), the XML format the European Parliament has used
|
||||||
|
since 2016 for legislative texts.
|
||||||
|
|
||||||
|
ELI synthesis in v0.1.0 is a deterministic fallback because
|
||||||
|
Germany lacks an upstream Bund-level ELI registrar. Replace once
|
||||||
|
BMJ publishes ELI URIs upstream.

//! `source.eu-recht` module — fetch one EU legal act from EUR-Lex
|
||||||
|
//! by CELEX number and hand its FORMEX-4 XML downstream, content-
|
||||||
|
//! addressed so a flow's audit trail pins the exact Gesetzesstand.
|
||||||
|
//!
|
||||||
|
//! # Capability
|
||||||
|
//!
|
||||||
|
//! - **Input:**
|
||||||
|
//! * `celex` — `text`, the CELEX identifier (e.g. `32016R0679`
|
||||||
|
//! for the GDPR, or a consolidated form like
|
||||||
|
//! `02016R0679-20160504`).
|
||||||
|
//! * `language` — optional `text`, two-letter EUR-Lex language
|
||||||
|
//! code (`DE` default, `EN`, `FR`, …).
|
||||||
|
//! - **Output:**
|
||||||
|
//! * `formex` — `bytes` (`application/xml`), the FORMEX-4 body
|
||||||
|
//! as served by EUR-Lex. Feed it to `text.akoma-normalize`
|
||||||
|
//! (0.2+) for the structured representation.
|
||||||
|
//! * `meta` — `json` SourceMeta (see below): CELEX, language,
|
||||||
|
//! the resolved URL, SHA-256 of the fetched bytes, and the
|
||||||
|
//! consolidation date when the CELEX carries one.
|
||||||
|
//!
|
||||||
|
//! # Versioning ("Gesetzesstand")
|
||||||
|
//!
|
||||||
|
//! EUR-Lex encodes consolidated versions in the CELEX itself
|
||||||
|
//! (sector `0` + `-YYYYMMDD` suffix). The module never guesses a
|
||||||
|
//! version: it fetches exactly the CELEX it was given and returns
|
||||||
|
//! `source_sha256` so downstream steps and the audit log can prove
|
||||||
|
//! which bytes the flow saw. Fetching "the same" CELEX later can
|
||||||
|
//! legitimately yield different bytes (EUR-Lex re-renders) — the
|
||||||
|
//! hash makes that visible instead of silent.
|
||||||
|
//!
|
||||||
|
//! # Scope
|
||||||
|
//!
|
||||||
|
//! Public EUR-Lex data only; no authentication, no personal data.
|
||||||
|
//! Network permission is pinned to `publications.europa.eu` (CELLAR,
|
||||||
|
//! the EU Publications Office store behind EUR-Lex).
