Bob,
Lest say you choose a name bobj
It would serve you well to put macros in a tiddler
$:/bobj/project-name/macros and tag it macros
In this case the project-name may be gallary-ops
So it you were using a viewTemplate it would be called
$:/bobj/gallary-ops/viewTemplate
This not only allows you to build the solution with a distinct set of
hidden system tiddlers for code etc but allows you to list export them as
[prefix[$:/bobj/gallary-ops]] and apply to another wiki.
You can then collect code into functional tiddlers and help those debugging
look for macros etc.. in the correct place by tiddler title.
Additional filters in a single tiddler could also list all relevant
tiddlers. Rather than tagging exhibitions artworks consignments etc.. set a
field object-type to each of these values. You can then list them with a
filter [object-type[artworks]] and save tags for ad hoc organisation.
Regards
Tony
