VikingMage, That is one approach that many of us currently take, which could be made easier, with "tiddler to json" and "json to tiddler" and "query tools" made available. These features are already in the core however not hackable or exposed as much as they could. For example;
- Drop one or more tiddlers or json files on a wiki - Edit the resulting $:/Import tiddler, this tiddler contains a json representation of the tiddlers already. - The Import process "extracts" them to actual tiddlers. Actually I think I will modify the import process to save imports to a JSON tiddler, or act on an existing JSON tiddler. - however the current methods treat JSON as only a tiddler storage. It limits what content the JSON has to tiddlers formats. Joshua's JSON tools open this up, and whilst we need not go the whole way with what is possible with Joshua's tools, we could go part way in the standard distribution.
