Ah, hadn't heard about that service! I don't think any publishers/databases are likely to use it on their journal article pages so I'm probably safe. But it does have a 'lovely' example of all the annoying punctuation a DOI can legally contain...

Even aside from the proxy prefix, the url in their browser may include (or consist entirely of) session gunk.

Am also considering that if DOIs also appear in the article's bibliography I'll need to make sure the javascript can distinguish between them and the DOI for the article itself; but a lot of this might be 'cross that bridge if I come to it' stuff.


Crap.  I just remembered :

        http://shortdoi.org/

... I don't know if any publishers are actually using them, or if they're just for people to use on twitter & other social media.

The real problem with them is that they don't have the '10.' string in them.

You can probably get away with just tracking the resolving form of them:

        http://doi[.]org/(\w+)

And ignore the

        10/(\w+)

form.
