Hello all We are trying to measure web accessibility of some Indian institutes/universities/libraries in the form of a score and then rank those institutes/universities/libraries against the score (still at the idea plane). The plan is to fetch data through API in a data wrangling software for further analysis. My questions are as follows: 1) Are there other services (apart from WAVE) that provide results in JSON format through API? 2) What is the significance of *ARIA* in determining such a score for web accessibility? Does a higher number of ARIA indicate a better accessibility? Or is converse true? 3) Is there any globally agreed-upon indicator for web accessibility?
