Issues with HYDRA

Hi , 

I am Vaibhav Chellani working on a parser to convert Open Api Documentation to Api Documentation for hydrus as my Gsoc Project with hydrus . While developing I came across some situations where I could not think of a way in which I could represent the api structure written using Open Api Specification in HYDRA Documentation , I hope you can help me in the problems discussed below :
Multiple Parameters at different locations : Data can be received at various locations in the form of parameters , for example “header”,”body”,”path”,”query” . At times we may receive some data from header and some from body in the same request . We get only one key ie “expects” to represent the parameters . The two questions here are 
 How to represent the location of input data(parameter)? 
 How to represent multiple vocab's in key “expects” along with the corresponding location of data ?
Templating  : How do I represent endpoints like ‘A/{id}/B/C’?

How do you think we can solve the above issues ? 



Best ,
