I want to develop a mobile app to access Indian tax treaties. India has entered into tax treaties with 100+ countries. Each treaty has about 25-30 articles. I want the app to have the following features:
1. ability to download the entire tax treaty - here, country will have to be selected
1A. ability to view a particular tax treaty
2. ability to view article of a particular tax treaty - here, the country and the article will have to be selected
3. ability to find - i.e search for keywords
4. comparison of two articles
5. trial version with option to pay for the full version
The tax treaties are available at http://www.incometaxindia.gov.in/Pages/international-taxation/dtaa.aspx. I can get an excel sheet prepared which would basically have different articles in different cells.
However, it would be an added advantage if you are good at extracting data from the web.
