Actually, re-reading some of the RFCs, I would clarify one thing.

It seems like using unregistered "x-" MIME type is discouraged, and instead you are encouraged to use what is (claimed to be) a very quick and easy and painless process of registering "vnd." types. So I'd encourage LC to investigate doing that for MARC, while waiting for someone to have time to do an actual (more time consuming) application/marc+xml registration. That would give us the beneift of an actual registration (albeit under vnc.) instead of an unregistered x-.

As far as text/xml, the general consensus on the internet seems to be that it was a mistake, but it's there and no one cares enough to try to somehow remove it, so it _is_ legal, but nobody really encourages using it. One problem with text/html is that it's default char encoding is ascii, while the default char encoding for XML is of course UTF-8. This can very easily lead to confusion and encoding errors unless software is more careful than we know most software has a tendency to be. :) Still, it's legal, but I don't see any reason to encourage it's use for MARC. application/xml, sure, but it would be _really_ useful, for the reasons discussed in last week's thread, to have a specific type for marc xml (and mods). If the folks at LC don't understand why, thinking that application/xml is sufficient, i could try to write up a persuasive essay again, or copy and paste from last week's thread. Or is there someone else other than LC who could conceivably fill out an application for application/marc+xml and application/mods_xml?

Seriously, application/xml is not sufficient, although it is legal.

We did indeed, and your summary is better than what my retort could
have been; spot on.

I guess it's hard to understand why text/xml is such a waste of MIME
and time as long as we still got text/html as the original understood
MIME for HTML pages, but luckily the internet has moved on and
evolved. :)

One question we haven't asked is if we really need a MIME type for MARCXML. :)
