I'm not sure whether a new identifier source code is required or not for Web of Science ResearcherID (previously Publons ID). Background ~~~~~~~~~~ System preference OPACAuthorIdentifiersAndInformation (added in bug 29948, which replaced OPACAuthorIdentifiers added in bug 29897), enables the display of authority record information about authors and contributors on OPAC record and authority detail pages.[1] The information that can be displayed includes identifiers for authors and contributors recorded in the authority record 024$2 and 024$a. The 024$2 requires valid codes to be set up with URL patterns so that when displayed they go to the website with that identifier. The current valid values are: - orcid (ORCID) - scopus (ScopusID) - loop (Loop ID) - rid (Publons ID) - viaf (VIAF ID) When these were created in bug 29897, rid was used for the Publons ID. rid is listed in the Library of Congress Standard Identifier Source Codes (https://www.loc.gov/standards/sourcelist/standard-identifier.html) as ResearcherID. Existing Publons IDs are redirected to the Web of Science ResearcherID. However, the new Web of Science ResearcherID URL and number used is different from the Publons ID - we can't just replace the URL pattern for rid with the new one, as it won't work with the older Publon IDs (see example below). Options: 1. We could just change the OPAC display name: . Don't change the exiting URL pattern, would redirect (see example) . Display name in OPAC: Web of Science ResearcherID (previously Publons ID) . The new WoS IDs would work with the old Publons ID URL pattern 2. Create a custom source value for Web of Science ResearcherID. However, if authority records are shared or imported, and they have 024$2 and 024$a information, then the data will end up being "messy". Example ~~~~~~~ - Monika Hestad (IDs from Wikidata https://www.wikidata.org/wiki/Q6900190) - Publons ID: 2601748 - Current URL pattern: https://publons.com/researcher/XXXXX (where XXXXX = Publons ID) - Publons ID URL: https://publons.com/researcher/2601748/ - Redirects to: https://www.webofscience.com/wos/author/record/16447 - New Web of Science ResearcherID is: K-8011-2013 - New Web of Science URL pattern works with the new ID: https://www.webofscience.com/wos/author/record/K-8011-2013 - Note that https://www.webofscience.com/wos/author/record/2601748 (using the old Publons ID) goes to a completely different person - Using the new Web of Science ResearcherID with the old URL pattern: . https://publons.com/researcher/K-8011-2013 . Redirects to https://www.webofscience.com/wos/author/record/16447 I've managed to confuse myself with this, and not sure what is the right way forward now! Hopefully, someone who is more familiar with the history with this ID will have a better approach....
