Lesson learned, the hard way: Let’s not do that again!

TL;DR We missed an error that led to resource resolution URLs of some 500,000+ records to be incorrectly updated. We have reverted the incorrect resolution URLs affected by this problem. And, we’re putting in place checks and changes in our processes to ensure this does not happen again. How we got here Our technical support team was contacted in late June by Wiley about updating resolution URLs for their content. It’s a common request of our technical support team, one meant to make the URL update process more efficient, but this was a particularly large request.

Some rip-RORing news for affiliation metadata

We’ve just added to our input schema the ability to include affiliation information using ROR identifiers. Members who register content using XML can now include ROR IDs, and we’ll add the capability to our manual content registration form, participation reports, and metadata retrieval APIs in the near future. And we are inviting members to a Crossref/ROR webinar on 29th September at 3pm UTC.

Documentation

XML query results and errors

Query results may be requested in three different formats: XSD_XML, UNIXREF, and UNIXSD.

UNIXSD is the recommended and most robust format, but XSD_XML is the default for many services for legacy reasons.

Possible errors returned by malformed or insufficient queries include:

  • an invalid XML query will return no result (<body/>)
  • either first page or author must be supplied
  • either ISSN or journal title must be supplied
  • unreasonable DOI found (an unreasonable DOI does not follow the expected DOI format (10.XXXX/yyy...) and/or exceeds 200 characters)
  • piped query must contain either 9 pipes (for journals) or 11 pipes (for books/conference proceedings)
  • either ISSN/ISBN or series/volume title must be supplied.
