IMHO, I am not sure there is a need for RDF-form.  Form is used to send
something to a particular server. In other words, it is application
dependent.  For instance, a simple login form ask your username and password
because it will be passed to the server as query parameters something like

username=xyz&password=abc

But different web application can use different name tag, a particular
server can do something like this as well,

uname=xyz&pswd=abc

Of course, we can standardize the vocabulary of username and password, so
everyone will describe their login like

_:someone ex:username "xyz";
          ex:password "abc".

But to send this "form", if you insist to call so, to someone who needs to
process it, you still need to know how they have designed their HTTP API,
right? In your case, you would describe your request with an ontology
between you and the repaired shop.  Then, wrap it in a HTTP form request
through the shop's web server or any kind Web service interface they
provide. But what can an RDF form do to help you? 

HTML is a presentation langague to interact with humans, and RDF is
description language used for machines. We cannot mess them up.
