Changelog & Roadmap

Changelog

This changelog is maintained starting from CPRMV / CPRMV API v0.4.0. Usage of earlier versions is deprecated and at own risk. Note that CPRMV / CPRMV API still is highly subject to change.

v0.4.1 (June 2026)

v0.4.1 - CPRMV

  • Updates URIs and documentation to mention 0.4.1 instead of 0.4.0 (vocabulary namespace https://standaarden.open-regels.nl/standards/cprmv/0.4.1#).
  • cprmv:RuleSet is now a subclass of FRBR Work (frbroo:F1_Work) instead of eli:LegalResource: a formalisation such as a business rule is not in itself a legal resource in the ELI sense (note eli:LegalResource is itself a subclass of FRBR Work).
  • cprmv:isBasedOn is now a subproperty of frbroo:R2_is_derivative_of instead of eli:based_on; it remains a subproperty of prov:wasDerivedFrom.
  • Documentation on properties added to the ReSpec specification.
  • Class diagram in the ReSpec docs now uses the Elk layout engine (rectangular edges) via PlantUML instead of Graphviz.
  • Fixes publication paths in the ReSpec document.
  • Adds a PDF version of the ReSpec (built with pandoc, committed to the repository).
  • npm run build (and full-package.json, which also generates the PDF and runs shaclgen) now also updates the ReSpec folder bundled with the CPRMV API.

v0.4.1 - CPRMV API

  • Updates URIs and documentation to mention 0.4.1 instead of 0.4.0 (serve-API/methods namespaces https://cprmv.open-regels.nl/0.4.1/…).
  • /ref endpoint reworked: the reference method is auto-detected from a single reference query parameter (the /ref/{referencemethod}/{reference} path form is gone). Now (partly) supports Juriconnect, ELI to EU CELLAR, the CPRMV API /rules rule-id path, and an experimental ELI style for NL (BWB/CVDR) references.
  • Bugfix: invalid arguments in a Juriconnect reference no longer cause an internal server error.
  • /cellar-by-celex now redirects to the CELLAR output instead of returning the CELLAR URL as text.
  • New /cellar-by-eli helper — works like /cellar-by-celex but accepts ELI references (only those explicitly linked to EU CELLAR documents; partial ELIs do not resolve).
  • Fixes a quote-escaping bug for certain BWB resources.
  • /rules always returns a cprmv:RuleSet with at least the selected cprmv:Rule as part of it, so RuleSet-level properties always travel with the rule.
  • The RuleSet instance returned by /rules now lives in the cprmv.open-regels.nl / operaton.open-regels.nl namespace instead of opencatalogi.open-regels.nl.
  • /rules automatically adds a provenance link to the source publication on BWB, CVDR, FMX4 and DMN RuleSets (prov:wasDerivedFrom, the superproperty of cprmv:isBasedOn).
  • /rules unformat now applies before serializing to any requested format (e.g. rdflib's n3), not only cprmv-json.
  • /rules transforms and dumps JSON in UTF-8 encoding.
  • Retrieving DMN files is now documented in the /rules Swagger docs.
  • Adds (basic) support for using the CPRMV API as an MCP server (/mcp).

v0.4.0 — Initial Release (February 2026)

v0.4.0 - CPRMV

  • More elaborated and updated RDFS/OWL/SHACL specification of CPRMV. Adds several new classes like types of methods. Adds start for alignment with ELI.
  • Changes the official cprmv URI to one that resolves to the respective documentation
  • Normative section generated from RDFS/OWL/SHACL in the ReSpec documentation
  • Generated class diagram in ReSpec documentation

v0.4.0 - CPRMV API

  • bugfixes around support for BWB schema (now supports circulaire’s)
  • Adds /respec section hosting the respec documentation (besides the official URI)
  • Adds /ref endpoint which is going to support all reference methods (but currently only implements juriconnect at a basic level)
  • Allows for retrieving DMN 1.3 rulesets published in acknowledged (in value list in cprmvmethods.ttl) Operaton servers (currently only operaton.open-regels.nl)

Roadmap

Completed

Feature Version
CPRMV / CPRMV API v0.4.1
CPRMV / CPRMV API v0.4.0
CPRMV v0.3.1

Planned

v0.4.x — Features & documentation

v0.4.x — CPRMV / ReSpec documentation (carried over)

  • Examples and link to RDF definitions in the ReSpec documentation.
  • Adds a :publication-location (or similar) property referring to where a RuleSet is officially published (distinct from :isBasedOn). On a RuleSet this would be repository.overheid.nl for BWB/CVDR, an ELI reference for Formex 4, and the Operaton server URI for DMN.

v0.4.x — CPRMV API (carried over)

  • Link to the /respec section from within the /docs section.
  • The /rules endpoint allows retrieving the raw unprocessed source (the whole ruleset, not transformed into a CPRMV ruleset when the source isn't one).
  • Improved and more complete support for BWB, CVDR, Formex 4 and DMN 1.3 by using the existing XML Schemas independently from XSL stylesheets (a generic single stylesheet for all schema-constrained XML standards).

v0.4.2 - CPRMV

  • Improved and more complete cprmv methods knowledge / value lists
  • Better defined relation with with official organisation registers (EU)
  • Start of a CPRMV-NL variant, based on MIM and CPSV-NL and the ROO
  • Adds acknowledgement of RegelSpraak as a FormalisationMethod and ALEF as tooling related to it
  • Adds acknowledgement of OpenFisca as a FormalisationMethod and tooling related to it

v0.4.2 - CPRMV API

  • Support for using the /rules endpoint to find multiple published ruleset’s, which is a modus separate from referencing a single published ruleset. In the case of multiple ruleset’s the CPRMV API returns a list with references RuleSets which can be used with the CPRMV API to retrieve them.
  • Support for utilizing organisation and product and services catalog information within references in the /rules endpoint.
  • Support for utilizing :isBasedOn relations within references in the /rules endpoint. It should be possible to refer to.
  • Support for using ELI and where possible juriconnect references for other publication methods than typically supported by these reference types.
  • Adds a /browser section offering a minimal viable web based GUI to browse organisations, services and rulesets. Offers a searchable tree control at the left and a resource viewer at the right from which should offer users to start processes related to the resources (as defined by services)
  • Adds user friendly access to method knowledge in the /browser section relating to defined services for governance on value lists
  • Adds basic support for RegelSpraak sources (depending on where these will get published)
