Martyn joined Crossref in June 2020 as Product Manager. Prior to that he spent seven years at open access publisher MDPI in various roles, including roles in production, editorial, and author services. Before moving into publishing Martyn was a researcher, developing instrumentation in life sciences, material sciences, and analytical chemistry. He completed his PhD at the University of Warwick before postdoc positions at the University of Reading and the University of Freiburg. Outside of work you can find him spening time with his family, making music, or exploring the Black Forest by foot or by bike.

Better preprint metadata through community participation

Martyn Rittman

Martyn Rittman – 2022 November 09

In PreprintsMetadataCommunity

Preprints have become an important tool for rapidly communicating and iterating on research outputs. There is now a range of preprint servers, some subject-specific, some based on a particular geographical area, and others linked to publishers or individual journals in addition to generalist platforms. In 2016 the Crossref schema started to support preprints and since then the number of metadata records has grown to around 16,000 new preprint DOIs per month.

Amendments to membership terms to open reference distribution and include UK jurisdiction

Tl;dr Forthcoming amendments to Crossref’s membership terms will include: Removal of ‘reference distribution preference’ policy: all references in Crossref will be treated as open metadata from 3rd June 2022. An addition to sanctions jurisdictions: the United Kingdom will be added to sanctions jurisdictions that Crossref needs to comply with. Sponsors and members have been emailed today with the 60-day notice needed for changes in terms. Reference distribution preferences In 2017, when we consolidated our metadata services under Metadata Plus, we made it possible for members to set a preference for the distribution of references to Open, Limited, or Closed.

Event Data now with added references

Event Data is our service to capture online mentions of Crossref records. We monitor data archives, Wikipedia, social media, blogs, news, and other sources. Our main focus has been on gathering data from external sources, however we know that there is a great deal of Crossref metadata that can be made available as events. Earlier this year we started adding relationship metadata, and over the last few months we have been working on bringing in citations between records.

Event Data: Help us fill in the gaps

UPDATE August 2, 2021: This work was awarded to Laura Paglione of the Spherical Cow Group. To date, we have collected around 740 million events from 12 different source since we launched our Event Data service service in 2017. Each event is an online mention of the research associated with a DOI, either via the DOI directly or using the associated URL. However, we know that there is much more out there.

An Advisory Group for Preprints

We are delighted to announce the formation of a new Advisory Group to support us in improving preprint metadata. Preprints have grown in popularity over the last few years, with increasing focus brought by the need to rapidly disseminate knowledge in the midst of a global pandemic. We have supported metadata deposits for preprints under the content type ‘posted content’ since 2016, and members currently register a total of around 17,000 new preprints metadata records each month.

Doing more with relationships - via Event Data

Crossref aims to link research together, making related items more findable, increasing transparency, and showing how ideas spread and develop. There are a number of moving parts in this effort: some related to capturing and storing linking information, others to making it available. By including relationship metadata in Event Data, we are taking a big step to improve the visibility of a large number of links between metadata. We know this is long-promised and we’re pleased that making this valuable metadata available supports a number of important initiatives.

Event Data: A Plan of Action

Event Data uncovers links between Crossref-registered DOIs and diverse places where they are mentioned across the internet. Whereas a citation links one research article to another, events are a way to create links to locations such as news articles, data sets, Wikipedia entries, and social media mentions. We’ve collected events for several years and make them openly available via an API for anyone to access, as well as creating open logs of how we found each event.

Fast, citable feedback: Peer reviews for preprints and other content types

Crossref has supported depositing metadata for preprints since 2016 and peer reviews since 2018. Now we are putting the two together, in fact we will permit peer reviews to be registered for any content type.

Using the Crossref REST API. Part 11 (with MDPI/Scilit)

Continuing our blog series highlighting the uses of Crossref metadata, we talked to Martyn Rittman and Bastien Latard who tell us about themselves, MDPI and Scilit, and how they use Crossref metadata.
