Crossref Similarity Check news: iThenticate v2.0 ready for launch
Last year, we announced the upcoming launch of a new version of iThenticate, the product from Turnitin that powers Crossref Similarity Check. We know some of you have been waiting a long time for this upgrade and we are very happy to share with you that we are now ready to release it.
We will be rolling out this new version in stages, so not everyone will be able to upgrade to the new version immediately.
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.
Crossref Conversations is an audio blog we’re trying out that will cover various topics important to our community. This conversation is between colleagues Anna Tolwinska and Rosa Morais Clark, discussing how we can make research happen faster, with fewer hurdles, and how Crossref can help. Our members have been asking us how Crossref can support open science, and we have a few insights to share. So we invite you to have a listen.
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.
The background We’ve been working on the Research Organization Registry (ROR) as a community initiative for the last few years.
A DOI may refer to a journal or book (a title-level DOI), or to a specific article or chapter.
Journals and DOIs
Like a set of nesting dolls, a journal may be made up of volumes, each containing a number of issues, each containing a number of articles. You can assign a DOI at each level, for example:
journal-level-DOI (sometimes called the title-level-DOI) 10.5555/QYPF2031. Like an ISSN, it refers to the whole journal
volume-level-DOI 10.5555/FFFU4804
issue-level-DOI 10.5555/QKLE5634
article-level-DOI 10.5555/CNBT7653
The role of the journal-level-DOI, volume-level-DOI, and issue-level-DOI is to link persistently to a point in the journal structure. These DOIs do not have any associated content, and it does not cost anything to register these DOIs.
However, article-level-DOIs do have associated content, and therefore a fee applies to register these DOIs.
Books and DOIs
Like a set of nesting dolls, a book may be made up of chapters. Again, you can assign a DOI at each level, for example:
book-level-DOI (sometimes called the title-level-DOI) 10.5555/ZAAR1365. Just like an ISBN, it refers to the whole book.
chapter-level-DOI 10.5555/TFWD2627
Both book-level-DOIs and chapter-level-DOIs have associated content, and therefore a fee applies to register these DOIs.
