  • Create a WHATWG-like spec using bikeshed
  • Add issues where appropriate
  • Semantically backwards-compatible with both 1.0 and 1.1

There is no formal body. Feel free to use the Github issues for discussion and questions. Pull requests are very welcome.

For quick questions you can use the hocr-spec gitter channel.

To build the spec, you will need to have GNU make and either bikeshed or docker installed.

Adapt <VERSION>/spec.md to change the body of the spec, <VERSION>/metadata to change the bikeshed metadata. Then run make VERSION=<VERSION> to build that spec.

Examples:

• To build the 1.2 version: make VERSION=1.2
• To build the 1.2-zh version: make VERSION=1.2-zh

The goal of this project is to make the hOCR specification more accessible and easier to maintain.

• Cross-reference other specs
• Harmonize style
• Add samples
