Publication Repositories¶

The CPRMV API supports four publication methods, each registered in data/cprmvmethods.ttl under the cprmvmethods:analysismethods or cprmvmethods:formalisationmethods collection. The method detection logic in serve.py (detect_cprmv_serve_acknowledged_method) walks these RDF lists and attempts to parse the incoming rule set identifier against the cprmv-serve:normalized-id-format pattern of each method.

BWB — Basis Wettenbestand (Dutch national law)¶

The BWB repository holds consolidated versions of Dutch national legislation. The API supports three identifier forms:

Form	Example	Behaviour
`{BWBID}_{DATE}_{INDEX}`	`BWBR0015703_2025-07-01_0`	Fetches the specific indexed publication
`{BWBID}_{DATE}_latest`	`BWBR0015703_2025-07-02_latest`	SRU search for version valid on that date
`{BWBID}`	`BWBR0015703`	SRU search for version valid today

For latest and bare-ID forms, the API queries the BWB SRU endpoint:

https://zoekservice.overheid.nl/sru/Search?x-connection=BWB&operation=searchRetrieve
  &version=2.0&maximumRecords=1
  &query=dcterms.identifier=BWBR0015703 and overheidbwb.geldigheidsdatum={valid-on}

The response identifies the publication XML at:

https://repository.officiele-overheidspublicaties.nl/bwb/{BWBID}/{DATE}_{INDEX}/xml/{BWBFILENAME}.xml

Transform: data/bwb2cprmv.xsl — converts BWB toestand XML structure (hoofdstuk / paragraaf / artikel / lid / li) to nested CPRMV Turtle with cprmv:id, cprmv:definition, and cprmv:hasPart relations.

CVDR — Centrale Voorziening Decentrale Regelgeving (municipal regulations)¶

The CVDR repository holds regulations from Dutch municipalities, provinces, and water boards. Identifier forms:

Form	Example	Behaviour
`{CVDRID}_{INDEX}`	`CVDR712517_1`	Fetches the specific indexed version
`{CVDRID}_{DATE}_latest`	`CVDR712517_2025-07-02_latest`	SRU search for version valid on that date
`{CVDRID}`	`CVDR712517`	SRU search for version valid today

SRU endpoint used for latest/bare forms:

https://zoekservice.overheid.nl/sru/Search?x-connection=cvdr&operation=searchRetrieve
  &version=2.0&maximumRecords=1
  &query=dcterms.identifier=CVD{rulesetid}_* and overheidrg.inwerkingtredingDatum<={valid-on}
  sortby overheidrg.inwerkingtredingDatum/descending

Transform: data/cvdr2cprmv.xsl.

EU CELLAR — European Union legislation (Formex v4)¶

EU legislation in Formex v4 format is fetched from the Publications Office of the EU. Identifier form:

Form	Example
`CFMX4{CELLAR_ID}_{ITEM_ID}`	`CFMX483e4752e-f2e5-11e8-9982-01aa75ed71a1.0017.02_DOC_2`

Publication URL:

https://publications.europa.eu/resource/cellar/{rulesetid}/{docid}

Date-based version resolution is not yet supported for CELLAR publications.

Transform: data/fmx4cellar2cprmv.xsl.

DMN 1.3 via Operaton (experimental)¶

Decision models deployed to the Operaton BPMN/DMN engine can also be fetched. The identifier embeds the Operaton deployment ID and resource ID:

Form	Example
`DMN1.3_{deploymentid}R{resourceid}_{date}_{index}`	(from Operaton deployment API)

Publication URL:

https://operaton.open-regels.nl/engine-rest/deployment/{deploymentid}/resources/{resourceid}/data

Transform: data/dmn13operaton2cprmv.xsl.

Experimental

The DMN 1.3 method is explicitly marked experimental. The deployment/resource ID extraction relies on a positional parsing hack in serve.py and is subject to change.

Analysis methods (non-publication)¶

cprmvmethods.ttl also registers analysis methods that are not publication endpoints — these describe how a rule set was analysed but do not provide publication URLs:

Method	ID
Law Analysis / Wetsanalyse (JAS)	`cprmvmethods:lawanalysis`
Calculemus / FLINT	`cprmvmethods:calculemusflint`

These are used to annotate rule sets via cprmv:hasMethod in TTL files but are not matched by the serve API's method detection for retrieval purposes.
