Persistent identifiers for people
Authors, researchers and generally creators of works are identified in the world wide web by many different PID systems, depending on the service they are using. The most commonly used persistent identifiers (PIDs) for people are the following:
arXiv Author Identifiers
arXiv seeks to accurately identify and disambiguate all authors of all articles in their archive. Since 2005, arXiv has used authority records that link user accounts with preprints. Since 2009, public author identifiers are offered once a user publishes their authored articles in arXiv for use in other services. arXiv allows users to link their ORCID iD with their arXiv authority records.
Google Scholar Profiles
Google Scholar offers author profile pages for the identification and disambiguation of publications by a certain author. Users can create their own profile in order to track citations to their works and get additional metrics such as the h-index and the i-10 index.
LinkedIn uses internal identifiers for profile pages to solve the name ambiguity problem. The ORCID iD can be added to LinkedIn profiles.
The 'Open Researcher and Contributor ID' (ORCID iD) is a type of PID that is compatible with the 'International Standard Name Identifier' (ISNI). ORCID iDs were designed specifically for the research community. They are issued without cost by the open, non-profit, community-driven organization 'ORCID'.
ORCID (Open Researcher and Contributor ID) is a non-profit organization supported by a global community of organizational members, including research organizations, publishers, funders, professional associations, and other stakeholders in the research ecosystem.
Researchers registered with an ORCID iD can use the ORCID registry’s transparent linking mechanism to pull in data from other PID platforms such as arXiv, INSPIRE, Crossref, DataCite and Zenodo to create their own verifiable research profile. Publications, funding bodies, websites, datasets etc. can be added automatically to the researcher’s profile if the ORCID iD was used.
ORCID provides an API to support system-to-system communication and authentication. The many relationships identified through the ORCiD registry result in a more satisfactory discovery process for those seeking research findings, as well as more efficient distribution of research funding and stronger collaboration within the research community.
In addition, ORCID is closely connected to other platforms and services such as INSPIRE and Zenodo, which helps you to save time and reduce the number of accounts and passwords to be remembered.
You can also use it for manuscript submissions to most of the major publishers. This means that you are able to access those platforms with your CERN credentials, since you can link your ORCID account with your CERN login.
For LHC papers in particular, the ORCID iDentifiers are being added to the XML list of authors included in the arXiv submission, automatically extracted on INSPIRE, and therefore improve the identification of individual authors in the collaboration.
It is finally important to keep in mind that several CERN member states now require that researchers provide an ORCID record in the framework of their national research assessment system.
The citation database Web of Science offers their own author identification service to ensure that publications are correctly attributed to authors across Web of Science collections. The ResearcherID is used to aggregate publications and track citations of a specific author. The identifier can be used with services like Publons.
