Hello Muharaf team,

I am developing an Arabic OCR system for printed, handwritten, historical, and low-quality scanned documents.

Could you please provide the official download links and documentation for the Muharaf dataset, including:

• the public dataset files;
• any restricted or extended portions, if available;
• page or line images;
• corresponding ground-truth transcriptions;
• annotations such as JSON, PAGE-XML, ALTO XML, or metadata;
• official train, validation, and test splits.

I understand that the public portion is listed under CC BY-NC-SA 4.0 and that some restricted data may be research-only.

Could you please clarify whether I may:

1. use the dataset to train or fine-tune another OCR or vision-language model;
2. create internal augmented or degraded copies;
3. publish benchmark results and training/integration code;
4. publish LoRA adapters or trained/merged model weights;
5. use the resulting model in a future commercial product or paid API;
6. retain the original dataset privately without redistributing it;
7. use any restricted portion under a separate commercial or research agreement.

Please also clarify:

• whether trained model weights are considered derivative works;
• whether share-alike requirements apply to trained weights;
• whether a separate commercial license is available;
• any applicable fees or contractual conditions;
• the required attribution wording;
• whether any source manuscripts or third-party assets have separate restrictions.

I previously contacted the team by email and am posting here in case GitHub is the preferred communication channel.

Best regards,
Ahmad Sayed
