It'd be nice to solve these for math and timelines as well -- perhaps a
I was thinking about this problem, but for Graphviz (which is based on
Timeline, which was the source of the problem).
Instead of opening a tag and dumping graph/timeline code in the article,
we have a namespace where articles are parsed as graph/timeline code
(some extra syntax needed in order to put some wikitext in the same
article). Then, in article pages, you insert a link like [[Graph:Graph
title|options|description]] or [[Timeline:Timeline title|...]], and they
are inserted just like images are.
This has a few advantages:
- Graphs or timelines (or music scores) that appear in multiple pages
are maintained in a single central article, changes in it propagates to
all pages that include that object, just like it is with images;
- It becomes easier to edit article pages, because you have only
wikitext to look at, and not a mix of wikitext, dot syntax, timeline
- Perfect garbage collection: we produce no garbage. In-disk files are
linked to special article pages; if someone deletes the article, MW just
wipes all files with that given hash and you are done. Any file without
a matching article in that special namespace is easily marked as garbage.
