Chains of RFCs and Chains of Laws?

AlexNicoll writes "I recently completed a DNSSEC library for the .NET platform (thanks to Wouter @ NLNetLabs for his help!). While writing the library, I encountered the extremely entertaining concept of following the long chain of DNS-related RFCs on the IETF website. Some RFCs were obsoleted, some were updated, some updates were obsoleted by others, and some were never really formally related or linked — so even finding them was a challenge in search-fu. Finally, I think I got the whole picture, but I'm not sure. Then I got to thinking: searching for the relevant RFCs in IETF RFC chains was a lot like trying to figure out how (in the US) local, regional, state, and federal laws interact with themselves and each other. Since I just recently moved, I thought I ought to know the rules of the place I live in. It turns out to be just as non-trivial, if not more so, than parsing RFC chains. So here's the question: given that the processes are somewhat similar, does anyone know of a project that has tried to consolidate all the information in one place, so that it's in one comprehensive and up-to-date document, for either laws or RFCs?" Update: 05/24 14:24 GMT by KD : Ray Bellis from Nominet took up the challenge and compiled dependency graphs for DNS-related RFCs.
