For namespacing we can take a pointer from MIME types:
1. Keys used by core OpenSim will have no prefix, e.g. "media" or
"prop.attr".
I'm not very comfortable with this, I think it would better if such attributes
started with core. or even c.
I also think it would be better to enforce storage in a completely separate map rather than making this part of the key
name. Perhaps that's too fussy.
2. Keys created outside core OpenSim will use the "vnd." prefix, followed by
the name of the creating entity. For example: "vnd.acme.myprop".
What would vnd stand for? My preference would be not have this but just
something like acme.myprop instead.
We should stick to storing the data in a single field. Database access is
much slower than in-memory string manipulation, so for any reasonable amount
of data it would be faster to read and write it as part of the existing
"prims" table rather than adding additional SQL operations on another table
("primattr"?). And of course, a separate table would be much more
complicated to handle and I do like the simple life :)
It might be worth putting a limit on the amount of data stored, to stop any
region module massively filling up the space.
