Public release 0.1.1 contains only a small, explicitly identified corpus sample for pipeline verification. It is not a target-scale pretraining corpus and does not support model-quality claims. The scientific corpus remains under construction. Aggregate counts, source shares, and token counts are not reported until a content-addressed snapshot passes the legal, privacy, lineage, duplicate, and contamination gates. ### Materialized validation snapshot The underlying snapshot contains eight synthetic pt-BR documents drafted with AI assistance for this project, reviewed and adopted for release by the project owner. All eight records passed the production license and provenance boundary; none was rejected, quarantined, or marked as a duplicate. This verifies the data path but is not scientific training data. | Artifact | SHA-256 | |---|---| | source JSONL | `6896439e772f212c2848846f1f908410a606d81cd8845583024c16496a07979f` | | corpus manifest file | `afbd872b05f61ffc8acf11e436949fb760f9456a3eda62dc11a67ed1511d8841` | | logical corpus manifest | `fcb1af582f5ded8ecbe2b67e1da2b391f3fcf17678feba6389cf4a211d82ff5d` | | audit report file | `c99b951ab4cf79356930e3ea5fdfe8269aaa6cbc7142fa6c26a054ce32f02d9e` | | logical audit report | `af0dbeb4f1f75e3dce14bc5f317b584bcd4b7a662e48c2365f11efe484ed0711` | | Parquet file | `e2b5d4c01739e92240cfe99e6dccebce3903729d083e61e86afa37f6dd86c8a2` | The snapshot is published with its Parquet file, source JSONL, source and license registries, audit report, and content-addressed manifest. ## Dataset purpose The dataset supports research on from-scratch Brazilian Portuguese language-model pretraining under document-level rights and provenance controls. Every publishable record must link its normalized text to: - a canonical source and source revision; - a raw snapshot hash; - a rights basis and exact license when applicable; - a digest of the rights assertion and, for scientific records, the archived evidence bytes and media type; - attribution and share-alike requirements; - an ordered transformation chain; - language variant, domain, stable group, and split; - PII, third-party-content, and takedown decisions. Public availability alone is not sufficient. Missing, unknown, noncommercial, and no-derivatives rights fail closed. ## Initial source policy Eligible source families are: - dated official Portuguese Wikimedia dumps under applicable CC BY-SA terms; - verified Portal da OBMEP items under CC BY 3.0 Brazil; - Brazilian official acts covered by Article 8(IV) of Law 9,610/1998; - ProEdu items with exact CC0, CC BY, or CC BY-SA terms; - SciELO Brasil articles with exact item-level CC BY 4.0 terms. The initial release rejects aggregate ingestion from BrWaC, Carolina, CulturaX, mC4, OSCAR, HPLT, Common Crawl, GigaVerbo, GigaVerbo-v2, and mixed LegalPT collections. Those packages do not by themselves establish a homogeneous rights chain for the underlying text. ## Published fixture schema The Parquet file in this release contains exactly these columns: `document_id`, `text`, `normalized_content_sha256`, `split`, `normalization_id`, `source_id`, `source_url`, `canonical_url`, `retrieved_at`, `license_id`, `rights_basis`, `attribution_text`, `creator`, `publisher`, `publication_date`, `source_revision_id`, `source_snapshot_sha256`, `contains_third_party`, `pii_status`, `provenance_sha256`, and `evidence`. ## Planned scientific-corpus contract The future scientific corpus is planned to include the following core fields. This table is a contract for a later release, not a description of additional columns hidden in the current fixture: | Field | Meaning | |---|---| | document_id | stable source and revision identifier | | group_id | split-safe work or revision family | | text | normalized training text | | source_id | audited source-registry identifier | | source_url | acquired record URL | | canonical_url | authoritative public identity | | source_revision_id | immutable source revision | | source_snapshot_sha256 | acquired snapshot digest | | raw_content_sha256 | raw item digest | | normalized_content_sha256 | normalized text digest | | language | BCP 47 language tag | | language_variant | Brazilian, European, mixed, or undetermined | | domain | registered content domain | | rights_basis | license, statutory exclusion, or other reviewed basis | | license_spdx | exact SPDX expression where applicable | | license_url | authoritative license text | | evidence_url | rights evidence | | license_evidence_sha256 | digest of the recorded evidence assertion | | attribution_text | required attribution | | transformation_chain | ordered versioned transformations | | split | deterministic group-aware split | | pii_status | personal-data review state | | takedown_status | active, quarantined, or removed | Additional fields are documented in the research repository. A record missing a required release field is rejected. ## Licensing Public release 0.1.1 contains only the eight project-controlled synthetic fixtures. The owner releases them under Apache-2.0 to the extent of his rights; AI-assisted text may not be unique. No third-party corpus record is present. A future mixed scientific corpus will use source-specific terms and must not be added under this blanket metadata. Wikimedia, Creative Commons, and statutory source records would retain their applicable terms and attribution. Model-weight licensing remains a separate decision. ## Processing The registered flow is: 1. immutable source acquisition and hashing; 2. rights-evidence validation; 3. text extraction; 4. lossless NFC and control-character normalization; 5. language, quality, PII, and policy classification; 6. exact and near duplicate detection; 7. benchmark decontamination; 8. deterministic group-aware splitting; 9. license-separated Parquet release; 10. content-addressed token-shard construction. Every transformation records code version, parameters, input digest, and output digest. ## Limitations - The current sample is too small and too synthetic for language modeling. - Registry statement hashes are tamper-evident metadata, not independent legal proof. Scientific records additionally require hashes of archived source or license bytes before inclusion. - Automated PII, language, and duplicate checks are imperfect. - A source-family allowlist does not replace item-level review. - Share-alike effects on any future combined release require final legal review. - Takedowns create new corpus revisions and may affect future model releases. - The current eight-document fixture has no external benchmark content and no observed personal data; this does not validate future corpus content. ## Maintenance Initial author and maintainer: Guilherme Monteiro, FIAP ORCID: For correction, attribution, or withdrawal requests, open a Community discussion in this Hugging Face repository and cite the commit, document ID, and requested action. Do not post sensitive personal data; request a private follow-up when necessary. A credible urgent report can cause the repository to be hidden during review. Confirmed changes receive a new version and manifest. The scoped approval and rights review are published in `PUBLICATION_REVIEW.md`; the machine-readable removal history is `takedown-ledger.json`.
