+# Tibetan OCR — Stok
+
+<!-- DRAFT. Open-access subset of the OPTranskribus alignment set. Numbers measured 2026-08-18. -->
+
+**806 page images of Tibetan Kangyur manuscripts (uchen) with page-level Unicode
+transcriptions.** The transcriptions were produced by **[OpenPecha](https://openpecha.org/)**
+with the [Transkribus](https://www.transkribus.org/) handwritten-text-recognition
+platform over **BDRC** manuscript scans of the **Stog Palace Kangyur** (`MW22083`) and
+the **Phukdrak Kangyur** (`MW2KG210295`), then aligned to the page images. This is the
+**open-access subset** that can be shared freely.
+
+Used in the **BDRC Tibetan OCR** effort; see the model
+[`BDRC/tibetan-ocr`](https://huggingface.co/BDRC/tibetan-ocr) and the
+[evaluation benchmark](https://huggingface.co/datasets/BDRC/tibetan-ocr-benchmark).
