managing tiddlers across bags / spaces

[Tobias Beer]

Hi Chris,

Is it possible to search a tiddlyweb store via javascript remoting and retrieve all (readable or perhaps only writable) tiddlers from any bags (accessible to me) that have a certain tag (or even field / field value)?

Background: a GTD style app space that retrieves tiddlers with specific tags from any given spaces (/bags)... yet not necessarily loading the entire tiddler bodies, e.g. to list all tiddlers that have a tag "star" as...

* [[bag-name|link to space]] | [[tiddler-name|link to tiddler]] (last modified)

...sorted alphabetically... the actual display magic of course being done in Javascript.

Assuming write priviledges, I'd also like to be able to create a ui to "remotely edit" tiddlers thusly listed, e.g. remove or add tags (or add custom fields / edit custom field values) and, most importantly, write changes back to the corrsponding bags, again using Javascript remoting ...assuming error handling capabilities, e.g. for edit conflicts.

Does TiddlyWeb offer the webservices required to do so? How much wishful thinking is all this?

Tobias.

Search functionality depends on which store you are using and what
(server side) plugins you are using.

For example tiddlywebplugins.mysql3[1] provides the /search
functionality on tiddlyspace, and tiddlywebplugins.whoosher[2] provide
the /hsearch functionality. Neither of these require tiddlyspace.

Mysql search can:

* search fields
* is generally better for exact matches on attributes of a tiddler
(tags, fields, modifier, etc)

The whoosher search is:

* more oriented toward searching the text of tiddlers
* does relevancy ordering
* doesn't automatically search fields (but can be set up to do so)

As with any tiddler collection presented by TiddlyWeb, you can use
javascript to retrieve a JSON representation of the tiddlers (either
"fat" or "skinny") and then present them however your client side code
desires.

Compare the output of the following to see the difference between fat
and skinny:

http://tiddlyspace.com/bags/tiddlyspace/tiddlers.json?fat=0
http://tiddlyspace.com/bags/tiddlyspace/tiddlers.json?fat=1

Have you see the http://edit.tiddlyspace.com/ ?

Something like that could be made to work on plain tiddlyweb.

What you're describing is exactly what TiddlyWeb is for.

Have a look at the HTTP API description:

http://tiddlyweb.tiddlyspace.com/HTTP%20API

[2] https://pypi.python.org/pypi/tiddlywebplugins.whoosher
