++. And I would add that those who desire the XML format support should
do the coding. We've seen what happens when developers who don't work
with XML every day try to add support for it -- and try to maintain it
This is the reason Glance never supported XML. The developers of Glance
don't work with XML and we didn't want to add a half-baked format that
we weren't comfortable with maintaining.
I understand George Reese believes this makes Glance itself half-baked,
but there hasn't been anyone demanding XML format support in Glance yet
that hasn't easily and simply used the JSON format that Glance already
supports. In other words, people asked for XML support in Glance to
check off some "enterprise checklist", but when push came to shove,
nobody really needed it to begin with.
The only tenable solution proposed for this -- and I'm not sure whether
it was George who suggested it or someone else -- is to have XML
serialization driven from a JSON converter, so that you don't have to
maintain multiple format definitions, only the JSON format definition
that can be translated to XML. That way you don't need to maintain lots
of code, only a decent JSON -> XML translation engine that feasibly
could go into openstack-common...
