Re: No query string parameters in HTTP Vocabulary?

Dear Shadi,

Thank you for your response. Indeed, the query string parameters are 
part of URIs more than HTTP itself. The vocabulary specification 
mentions as main purpose theability for "quality assurance tools to 
record the HTTP headers that have been exchanged between a client and a 
server". I understand the focus on headers although, from my 
perspective, parameters may be equally important in order to understand 
the communication between two parties. I'm not sure if this choice may 
refrain the HTTP vocabulary adoption.

In addition to recording a communication that has already happened, 
another use case I foresee would be to describe how a (future) 
communication should take place, denoting possible headers as well as 
the URI used to invoke a service. This could be achieved using URI 
templates (RFC 6570), as illustrated by several initiatives such as 
Hydra <https://www.hydra-cg.com/> [1] or Triple Patter Fragments 
<http://www.hydra-cg.com/spec/latest/triple-pattern-fragments/> [2]. 
RESTdesc [3] is another work that attempted to complement HTTP 
vocabulary with properties tracking query string parameters.

I'll let you know if I see any works attempting to extend HTTP 
Vocabulary in this respect.

Best regards,
