I've been trying to fully understand the ways you can record, edit,
and retrieve structured data in a TW. So far, I see the following as
the options:
- tables within a tiddler
- slices, where a field name is followed by the field value, and by
using the ForEachTiddler plugin, you can retrieve the field values
into lists and output displays.
- Form and Data tiddler plugins, using HTML forms within tiddlers to
format data, which can also use the ForEachTiddler plugin.
- custom fields, which seem to require changes in the Edit and View
templates and affect all tiddler in the file. And again, the
ForEachTiddler plugin can be used to retrieve values from multiple
tiddlers
These seem to be the options, as I understand them. I am successfully
using the first three methods, as they meet my needs in various
applications I've built; the latest using slices. At work, I have not
been able to import a copy of the FormTiddler plugin (I have
DataTiddler plugin loaded and it should work when I get it's partner
in shop).
But I really am not sure about custom fields yet, even after reading:
http://tiddlywiki.org/wiki/Getting_started_with_custom_tiddler_fields
It looks as simple as modifying the edit and view template to add
lastname, firstname, and contactinfo and those fields would appear on
every tiddler in the file, making a phonebook (yes, I know about
twab). Am I understanding this correctly? And, are there other
structured data techniques I've missed?
