ORDID and ResearcherID and Scopus, oh my! It is just me, or are there an increasing number of unique identifiers popping up in Library Land? A person can now be identified with any one of a number of URIs such as: * ORCID - http://orcid.org/0000-0002-9952-7800 * ResearcherID - http://www.researcherid.com/rid/F-2062-2014 * Scopus - http://www.scopus.com/authid/detail.url?authorId=25944695600 * VIAF - http://viaf.org/viaf/26290254 * LC - http://id.loc.gov/authorities/names/n94036700 * ISNI - http://isni.org/isni/0000000035290715 At least these identifiers are (for the most part) “cool”. I have a new-to-me hammer, and these identifiers can play a nice role in linked data. For example: @prefix dc: <http://purl.org/dc/elements/1.1/> . <http://dx.doi.org/10.1108/07378831211213201> dc:creator "http://orcid.org/0000-0002-9952-7800" , "http://id.loc.gov/authorities/names/n94036700" , "http://isni.org/isni/0000000035290715" , "http://viaf.org/viaf/26290254" . How have any of y’all used theses sorts of identifiers, and what problems do you think you will be able to solve by doing so? For example, I know of a couple of instances where these sort of identifiers are being put into MARC records. — Eric Morgan
