UPDATE October 26, 2015
The auto-update feature is now live via a collaboration between ORCID, Crossref, and DataCite.
From the Cross Tech Blog:
In the next few weeks, authors with an ORCID iD will be able to have Crossref automatically push information about their published work to their ORCID record. It’s something that ORCID users have been asking for and we’re pleased to be the first to develop the integration. 230 publishers already include ORCID iDs in their metadata deposits with us, and currently there are 248,000 DOIs that include ORCID iDs.
Crossref represents over 5000 scholarly publishers and many of them ask authors for their ORCID ID and include it in the publication information they send us. Also it will mean less manual searching and adding; you’ve always been able to search crossref metadata for your name and/or publications and manually add them to your ORCID record, this auto-update simply means that when your publishers include the info we can update and add work(s) to your ORCID record automatically for you.
