I'm not really convinced about this.

Looking at the wiki page http://wiki.audacityteam.org/wiki/LV2_Categories
Categories do not need to be standard LV2 categories. Apparently there
are already additional Audacity specific categories.
If these categories mean anything, shouldn't those Audacity specific
URLs provide a definition of those categories rather than a "Not
found" error?

I'm not suggesting that we need to create those definition because
they are not currently used and there is no indication that they will
ever be used in the future. On the same basis it seems to be a waste
of effort to include them in plug-ins.

Yes it is possible that someone could build Audacity from source with
categories enabled, but do we know for sure that it still works?

Or we could invent:
;categories "http://audacityteam.org/namespace#Exemplar"
or similar.

I think that would be better than "Sample", but "Example Analyze
Nyquist Plug-in" is still rather a long name. All that the name needs
to do is to identify the plug-in. Simply calling each of them
"Example" would be sufficient for that purpose.
