There are actually a number of http URLs that work like
One of them is
Another is run by crossref;  Some OpenURL ink servers also have doi
proxy capability.
So for code to extract the doi reliably from http urls, the code needs
to know all the possibilities for the doi proxy stem. The proxies also
tend to have optional parameters that can control the resolution. In
principle, the info:doi/ stem addresses this.
Again we have moved the discussion to a specific resolution mechanism,
e.g., OpenURL.  OpenURL could have been defined differently, such
that rft_id and rft_idScheme were available and you used the actual
DOI value and specified the scheme of the identifier.  Then the issue
of extraction of the identifier value from the URI goes away, because
there is no URI needed.
