This means that the things without hashes on can be found rapidly from the thing with a hash, and there is an object there of a class which can have retreival information hung off it. For example, I use it when counting how many occurrences of each namespace are to be output, and I plan to use it when zooming though a query to check that all the schemata have been loaded, in "think usingschemas" mode. > In thing.py, why does the Symbol class > not include stuff like <foo#bar>? > becase i couldn't call them both Symbol. In fact, the mapping of the language structure to the software class hierarchy doesn't work well. For example, formuale and bnodes at the moment have identifies (with #) and so while that identifier is arbitrary, there is sofware wise that in common between for example a Formula and a regular foo#bar symbol. > I would think that contact:homePage > is a symbol. > Yes it is a symbol.
