A dataset of more than 14,000 texts that is continuously increasing in quantity and quality through contributions from core members and apps that use our APIs.
Files are stored in the OpenPecha format(OPF), in which standoff markdown in annotation layers are linked to a base text layer.
OPF includes a base layer, a table of contents layer, a footnotes layer, and a hyperlinks layer by default.
Virtually unlimited additional layers can be added for witnesses, commentaries, layers of same-type tags, and more.
OpenPecha's Character Coordinate Translation Vector (CCTV) ties tags in annotation layers to characters in the base layer. Whenever a character in the base layer changes position, annotations that link to it are automatically updated to point to its new coordinates.
