rfcgraph is a simple Python script that uses Graphviz to generate a very large graph showing the relations between RFCs.

Green arrows indicate an update:

  • "RFCx RFCy" is read as "RFCx is updated by RFCy".

Red arrows indicate an obsoletion:

  • "RFCx RFCy" is read as "RFCx is obsoleted by RFCy".



To run rfcgraph, you'll need to get a copy of the RFC index XML file rfc-index.xml from rfc-editor.org. Then run:

./rfcgraph.py -h

to see the usage.

Note that rfcgraph and graphviz are very memory intensive. On the order of 2-2.5GB of RAM is needed to generate the full graph.
