Is it necessary to call "org-store-link" before calling "org-capture" to
extracet the informations used by theses keywords ?

Or did I missundertant how it work ?

I found the documentation unclear about this.

Is there a way to discover the keywords that a major mode provide to a
capture template ?

A new parameter added to the org-protocol url is only accessible through
the ":query" key ? It will not create a new "%:keywoard" automatically ?



What I would love to do, is creating a Firefox extension that can
extract different metadata from known well known web site and pass them
to an Org-mode capture through org-protocol.

For example, for a book, extracting author, title, year, etc.

And then, I could simply create a capture template that would use the
keywords "%:author", "%:title", etc.

I was also thinking, instead of a Firefox extension, creating an Elisp
function that take a web page URL as parameter, extract the metadata
from the web page and then call Org-capture providing the keywords
"%:author", "%:title", etc, to the template.

But I don't know how to do the last part and I cant found documentation
about it. And with this second solution, I don't know how to make it
work with org-protocol. As an org-protocol call result directly in an
Org-capture call. And extracting metadata from Firefox give more
flexibility on manually selecting information to extract on the web page.
