RCL Legislacja Consultations Metadata

Staging dataset-source artifact for Polish Dynaword / Slayer dataset research.

This private repository contains metadata, raw HTML snapshots, restricted source documents and extracted-text payloads from public legislacja.gov.pl RCL legislative-process pages. It is intended for source inventory, provenance review, manual review queueing, legal/PII screening and future controlled data-mix decisions.

The current main revision includes unreviewed payloads under raw_documents/ and extracted_text/. See RESTRICTED_SOURCE_NOTICE.md. Their presence in this private repository does not assign a blanket open license or clear any row for training or unrestricted redistribution.

The repository-level license metadata does not assign a blanket open-content license to RCL documents. Rights and reuse status must be reviewed at document or source level before text is released or included in a training corpus.

Contents

  • rcl_inventory/ - full project-list inventory for law projects, 2606 projects.
  • rcl_2026_consultations/ - 2026 consultation metadata batch, 150 projects.
  • rcl_2025_consultations/ - complete 2025 project-of-law metadata crawl: 315 projects, 250 consultation catalogs, 5556 document records and 4166 selected-document review rows. Raw public HTML snapshots are retained for provenance; document binaries are not included.
  • rcl_2026_consultations/review_queue.csv - manual-review queue generated from selected consultation documents.
  • */raw_html/ - raw public HTML snapshots used for auditability.
  • */runs/ - run summaries with crawl arguments and evidence counters.
  • rcl_gold_pilot_v0_1/ - content-addressed manifest, checksums, run evidence, extraction metadata, machine-observations and annotation evidence for the bounded 40-document review pilot, with restricted raw and extracted payloads.
  • rcl_gold_pilot_v0_1/legal_review_pack/ - metadata-only legal review queue with document provenance, working legal premise, PII flags and empty decision fields for legal reviewers.
  • rcl_remaining_consultations_v0_1/ - source-processing batch with restricted payloads for the 42 review-queue rows not included in the accepted pilot; now accepted into that batch's annotations.csv and queued for legal review.
  • rcl_2026_selected_remaining_918_v0_1/ - source-processing batch with restricted payloads for the remaining 918 rows from the 1000 selected-document queue after the accepted 82 rows.
  • rcl_2025_selected_v0_1/ - source and extraction evidence for 4166 selected 2025 consultation documents. It contains content-addressed manifests, checksums, machine observations, validation reports and restricted raw and extracted payloads.
  • rcl_2026_delta_20260826_v0_1/ - incremental source and extraction evidence for 8 newly selected document URLs found in the 2026-08-26 source check, including restricted raw and extracted payloads.
  • rcl_dynaword_handoff_v0_1/ - metadata-only Polish DynaWord adapter package: 1000 candidate rows, schema mapping metadata, token-count proxy, row-level blockers and source datasheet. It intentionally has no text column and no raw or extracted text payload.

Intended Use

This is not yet a cleaned training corpus. Treat it as a dataset-source and provenance object. Before inclusion in any training mix, documents need source review, PII screening, legal/provenance decisions and extraction quality checks. The 82 accepted review rows are review evidence only; all keep legal_status=review_needed. In this release, review_needed means the source is a public official RCL/RPL document with a plausible public-sector information reuse path, but no blanket dataset license has been assigned and legal review must still verify attribution, reuse, copyright/database-right and PII constraints.

The 918-row batch contains machine observations and draft suggestions only. It has not been human-accepted and does not clear any row for release or training.

The 2025 batch is also unreviewed. Its extraction and PII fields are machine triage evidence only. The metadata-only publication does not clear any 2025 row for text release, redistribution or training.

The 2026-08-26 delta is unreviewed as well. Its eight source rows remain blocked on legal, PII, extraction-quality and human-review gates. One duplicate content digest across distinct source URLs is retained as provenance evidence.

The DynaWord handoff package is an adapter/review artifact for possible future source inclusion and controlled ablation design. It must not be loaded as a training split until legal review, PII scrubbing and human review gates are complete.

The current private release includes restricted source payloads and must not be interpreted as a claim that source documents are licensed under Polish Dynaword's dataset license. The immutable v0.3.0-rcl-2026-08-26-metadata-delta tag preserves the preceding metadata-only publication boundary.

Slayer Ontology Mapping

  • Object: RCL source inventory / consultation metadata source.
  • Version: this uploaded snapshot.
  • Protocol: scripts/rcl_downloader.py and scripts/rcl_review_queue.py in the companion code repository.
  • Evidence: run summaries, document/category counts, extraction metadata and accepted calibration annotations.
  • Claim status: preliminary; candidate claims require manual-review evidence.

Legal Review Note

See rcl_gold_pilot_v0_1/legal_review_note.md for the working legal-review premise and source links for RCL/RPL public-sector information reuse review. See rcl_gold_pilot_v0_1/legal_review_pack/ for the row-level queue to be completed by legal reviewers.
