Open Stack

Hi,

At NTT Data, we work on system development projects with Swift.
Recently we have big interest in the metadata search feature of Swift, and now we're planning to construct a search function into Swift.

I checked some materials on wiki page http://wiki.openstack.org/wiki/MetadataSearch to consider a detailed plan.
I found some discussions about the metadata search, but I cannot find any information about recent progresses.
Is there any progresses about the metadata search ?

I also checked the API document http://wiki.openstack.org/wiki/MetadataSearchAPI to make the specification of our metadata search based on community's standard, and I think this specification has a full featured API.
However, the detail formats of HTTP request and HTTP response, such as headers and response codes, are not clearly defined in this specification.

These formats about a HTTP message are necessary for implementations of clients, and without strict definition, clients may get confused.

I added my suggestions about HTTP headers and response codes to the Wiki discussion page https://wiki.openstack.org/wiki/Talk:MetadataSearchAPI
Does anyone have comments?

p.s. I also found some typos in the chapter 10 and fixed them.

Best regards,
