Analyzing the chain (isnad) of hadith is essential for authentication. Comparison of the content (matn) of the hadiths can also be very helpful. I am looking for any computational tools that may exist for tracking chains of narrations or keeping up with all the different narrators, discontinuities, etc for different hadiths. Additionally, having a tool that could easily compare hadith contents would be helpful. I guess I could make my own for content analysis, I think, based on sunnah.con's API (IIRC).
Anything and everything that could be helpful would be appreciated! Even a family tree of narrators would be nice.
