# Wikipedia EN-FA Accessibility Bridge

Current, attributable English and Persian Wikipedia article snapshots for pages
created during a 69-day recency window, plus an EN↔FA
counterpart index and static accessibility signals.

The reproducible full baseline is the official **2026-08-01** Wikimedia dump:
**6,289,549 English articles without Persian**, **129,821 Persian
articles without English**, and **22,277,907 namespace-0 pages** in the
combined parity index. Redirects are retained in the parity index but excluded
from translation-ready article configs.
This first release covers **2026-06-03T00:00:00Z through 2026-08-11T20:23:26Z**. It contains **133,776**
current English pages and **12,716** current Persian pages. Among the
successfully fetched pages, **133,423 English pages lack a Persian counterpart**
and **5,868 Persian pages lack an English counterpart**. Full translation-
ready source text is included for **37,592 recently created English gaps**
and **1,132 recently created Persian gaps**; pages that already have a
counterpart remain in the compact parity index. The larger touched-page change
ledger is retained by the builder but is outside this new-entry release.

## Configurations

- `articles_en`: English wikitext and readable plain text for recently created
  non-redirect articles that lack a Persian counterpart.
- `articles_fa`: Persian wikitext and readable plain text for recently created
  non-redirect articles that lack an English counterpart.
- `parity_index`: compact status and EN↔FA counterpart map for all pages created
  in the window, including pages deleted or unavailable by fetch time.
- `full_articles_en_without_fa`: full English snapshot gaps as of 2026-08-01.
- `full_articles_fa_without_en`: full Persian snapshot gaps as of 2026-08-01.
- `full_parity_index`: every namespace-0 page in both 2026-08-01 snapshots.

Every article row retains page ID, current revision ID/timestamp/SHA-1, page URL,
history URL, and Wikidata QID when available. Recent article rows additionally
retain first and last event timestamps in the source window and whether the page
was created during that window; full-snapshot rows retain dump date and shard.

## What “recent” means

Wikimedia's monthly MediaWiki History dumps are used only as a metadata index to
discover namespace-0 page IDs created from June 3 through July 31. The live
MediaWiki Action API supplies the actual current wikitext, plain-text extract,
revision provenance, Wikidata item, and language link. RecentChanges supplies the
August portion. Therefore this is a dataset of **current snapshots of recently
created pages**, not a dump of every historical revision body.

## Accessibility fields

The article configs include counts and flags for heading-level skips, images
without explicit wikitext `alt=`, tables without detected header markup, math,
references, and mixed Persian/Latin directional text. These are triage signals,
not a claim of WCAG conformance or a substitute for testing rendered pages with
screen readers. A later semantic-HTML pass can prioritize pages flagged here.

## Privacy and safety

The source history contains contributor metadata, but this pipeline deliberately
does **not** retain editor names, IP addresses, user IDs, group membership, edit
comments, or blocks. It stores page/revision provenance needed for attribution
and reproducibility only.

## Licensing and attribution

Wikipedia article text is available under the Creative Commons Attribution-
ShareAlike 4.0 license, with additional terms described by Wikimedia. Preserve
the page URL, history URL, and revision fields when redistributing or creating
translations. MediaWiki History metadata and Wikidata structured data have CC0
terms; because this dataset includes Wikipedia text, the repository is labeled

## Translation workflow

This repository is the canonical source layer. Machine translations should go in
a separate derived dataset carrying the source page/revision identifiers, teacher
model and exact checkpoint, prompt, decoding settings, automated quality signals,
and human-review status. Generated translations are not silently mixed into the
Wikipedia source rows.

## Reproduction

The resumable builder and tests live in the Motarjem project. The release manifest
records every Parquet shard's row count, byte size, and SHA-256 digest.
