Hi Jim, I think what you describe is the standard TW tagging mechanism.
eg: - if you create a tiddler named "task" .. and - several tiddlers eg: - "Go to Mordor" - "Get the Ring" - tag those tiddlers as "task" What you get is a "parent" child relation between "task" = "parent" and "Go .." / "Get .." = "children" I'm using those examples, because you can find exactly that at http://five.tiddlywiki.com So you can open it and see the stuff described below. If you open the tiddler "Go to Mordor" you can see, that it is tagged "task" ... If you click the "task" pill, - You can see all other tiddlers tagged with "task" If you open the "task" tiddler - click the (i) info button - open the "Tagging" tab ... you'll see all tiddlers that are tagged with "task" IMO the mechanism is, (almost) what you described. ... But I think the implementation is different, to what you expect. ... because The "tagging" list is created at runtime. So if you click the "tagging" tab, the TW core searches for all tiddlers that are tagged "task" ... the tiddler named "task" doesn't contain a field "tagging" or in your case "children". IMO adding "parent" and "children" fields (or RDF tiddlers) can be done. But there is a whole lot of "syncing problems" that will pop up. Every time you rename / create / update / delete / import / export ... a tiddler, you'll need to check all tiddlers and keep them in sync. Exactly at that point you create a "real database" behaviour. ... and databases are kind of complicated, highly optimized beasts. ... I think a similar usecase was introduced by Leo at a hangout #19 [1]. IMO if we need a real database behaviour, we should use a real database. May be the storage is not so important, but I think the query language to retrive the data is ... and TW is no database, even if it is quite close :) After the hangout 19 I did stumble upon ArangoDB [2] which imo would be a nice backend for TW5. It supports tiddlers out of the box (key-value store) and it would be possible to create "real" graph indexes with a graph query language. @Jeremy, Did you know ArangoDB? have fun! mario [1] http://www.youtube.com/watch?v=wYaFsOzXnPY#t=509 [2] http://www.arangodb.org/ -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
