RDF is a schema-free system to represent data. However, most of the time I find myself writing a sort of well-known graph structure, and I have to build triple by triple. In the more general case, this well known graph structure is of course not guaranteed to be complete nor fixed (e.g. something else can be added). However, if a more o...

Using Python2.4.5 (don't ask!) I want to parse a query string and get a dict in return. Do I have to do it "manually" like follows? >>> qs = 'first=1&second=4&third=3' >>> d = dict([x.split("=") for x in qs.split("&")]) >>> d {'second': '4', 'third': '3', 'first': '1'} Didn't find any useful method in urlparse. ...
