Every HTTP library I have ever used parses HTTP headers and puts them in a nice hash for you ready to consume. If we go for "Name: Value" then that's all there is to it. If we go for "Attribute: name=value" as is currently proposed (which is arguably cleaner, follows cookies' "prior art" and avoids Amazon's prefix hack) then you just have to split on '='. To illustrate how clean this is by example: #!/usr/bin/python
import urllib2 response = urllib2.urlopen('http://cloud.example.com/myvm') representation = response.read() metadata = response.info() print metadata['occi-compute-cores']
As soon as you start talking about payloads you have to fire up a parser (JSON/XML/Atom/etc.) or write your own (previous text rendering) which is * significantly* more work to do at both design and run times. Not to mention more work for us to do now and more scope for interoperability problems. Sam
