ORCID
Springer can include ORCID for authors and editors of the proceedings to map the paper in the bibliometric info properly. See this announcement https://goo.gl/nAX4y8 and the guidelines https://goo.gl/oiMNAm (editor guidelines, section 4.7) for more information.
Authors are kindly requested to provide ORCID in their papers as an additional field of the authors' information.
The correct identification of the authors through their ORCID is crucial to correctly mapping publications and citations.
