Having a the same header repeated multiple times with different values is allowable by the HTTP spec. OCCI respects (OCCI always aims to respect the HTTP spec RFC2616) this hence why you may see two different renderings: one with all values "compressed" into one header line or multiple same headers with different values. If you "compress" each value must be ',' delineated. Note these rules also apply if the content is supplied in the body (OCCI specific).

Dear members of the occi-wg,

In the federated clouds working group, we are having a discussion about the interpretation of the HTTP rendering of the OCCI standard (document GFD.185, http://ogf.org/documents/GFD.185.pdf)

Our doubt is the following.

In several examples in the document, for examples in section 3.4, page 8 or in section 3.5.1, page 20, we see Category: elements laid out in multiple lines.

Our doubt is if this examples are normative, and thus it is acceptable to write them in multiple lines, or if this had been done just for readability, and the answers from the OCCI server should actually lay out a Category in a single line.

In the interest of interoperability among our different implementations, can you please clarify this point?

Thanks in advance,
On behalf of the Federated Clouds Working Group
