16 Nov Update: I've updated the diagram, and made it easier to read - the link now points to a pdf version. The same license applies as for the whole blog - Creative Commons Attribution-Share Alike v3.0. Do let me know, though - it's always interesting to find out how your work is used.
Some time ago, I was struggling to work out how I could evaluate a new social network analysis tool - one that made use of some obscure format. In order to give a new tool a fair test, I always use a specific group of datasets, that I know inside out. Almost inevitably, the new tool will require that they all be translated into some obscure format. But, given the tools already out there, there's always a chance that I can some combination of existing tools will do it for me. In the end, I drew a map to help me navigate this process.
Now, after many requests, I've revised the map. As before, if you have any more information, corrections, even objections, I will endeavour to respond - and quicker, this time. Mea culpa.
