Testing times

One of the challenges that we face in Labs and Research at Crossref is that, as we prototype various tools, we need the community to be able to test them. Often, this involves asking for deposit to a different endpoint or changing the way that a platform works to incorporate a prototype.

The problem is that our community is hugely varied in its technical capacity and level of ability when it comes to modifying their platform. Some mega-publishers, for instance, outsource their platforms and so are dependent on third party developers/organizations when they want to make a change. Many smaller publishers, by contrast, use systems such as OJS, which come with Crossref plugins that make life very easy… but that require hard code changes to accommodate prototypes. Such changes are way beyond the technical capacity of most journal editors.

Credential Checking at Crossref

It turns out that one of the things that is really difficult at Crossref is checking whether a set of Crossref credentials has permission to act on a specific DOI prefix. This is the result of many legacy systems storing various mappings in various different software components, from our Content System through to our CRM.

To this end, I wrote a basic application, credcheck, that will allow you to test a Crossref credential against an API.

Feedback on automatic digital preservation and self-healing DOIs

Thank you to everyone who responded with feedback on the Op Cit proposal. This post clarifies, defends, and amends the original proposal in light of the responses that have been sent. We have endeavoured to respond to every point that was raised, either here or in the document comments themselves.

We strongly prefer for this to be developed in collaboration with CLOCKSS, LOCKSS, and/or Portico, i.e. through established preservation services that already have existing arrangements in place, are properly funded, and understand the problem space. There is low level of trust in the Internet Archive, also given a number of ongoing court cases and erratic behavior in the past. People are questioning the sustainability and stability of IA, and given it is not funded by publishers or other major STM stakeholders there is low confidence in IA setting their priorities in a way that is aligned with that of the publishing industry.

A Request for Comment - Automatic Digital Preservation and Self-Healing DOIs

Digital preservation is crucial to the “persistence” of persistent identifiers. Without a reliable archival solution, if a Crossref member ceases operations or there is a technical disaster, the identifier will no longer resolve. This is why the Crossref member terms insist that publishers make best efforts to ensure deposit in a reputable archive service. This means that, if there is a system failure, the DOI will continue to resolve and the content will remain accessible. This is how we protect the integrity of the scholarly record.

Crossref Research and Development: Releasing our Tools from the Ground Up

This is the first post in a series designed to showcase what we do in the Crossref R&D group, also known as Crossref Labs, which over the last few years has been strengthened, first with Dominika Tkaczyk and Esha Datta, last year with part of Paul Davis’s time, and more recently, yours truly. Research and development are, obviously, crucial for any organization that doesn’t want to stand still. The R&D group builds prototypes, experimental solutions, and data-mining applications that can help us to understand our member base, in the service of future evolution of the organization. One of the strategic pillars of Crossref is that we want to contribute to an environment in which the scholarly research community identifies shared problems and co-creates solutions for broad benefit. We do this in all teams through research and engagement with our expanding community.

I’m delighted to say that Martin Paul Eve will be joining Crossref as a Principal R&D Developer starting in January 2023.

As a Professor of Literature, Technology, and Publishing at Birkbeck, University of London- Martin has always worked on issues relating to metadata and scholarly infrastructure. In joining the Crossref R&D group, Martin can focus full-time on helping us design and build a new generation of services and tools to help the research community navigate and make sense of the scholarly record.

Announcing our new Head of Strategic Initiatives: Dominika Tkaczyk

TL;DR

A year ago, we announced that we were putting the “R” back in R&D. That was when Rachael Lammey joined the R&D team as the Head of Strategic Initiatives.

And now, with Rachael assuming the role of Product Director, I’m delighted to announce that Dominika Tkaczyk has agreed to take over Rachael’s role as the Head of Strategic Initiatives. Of course, you might already know her.

We will also immediately start recruiting for a new Principal R&D Developer to work with Esha and Dominika on the R&D team.

Follow the money, or how to link grants to research outputs

The ecosystem of scholarly metadata is filled with relationships between items of various types: a person authored a paper, a paper cites a book, a funder funded research. Those relationships are absolutely essential: an item without them is missing the most basic context about its structure, origin, and impact. No wonder that finding and exposing such relationships is considered very important by virtually all parties involved. Probably the most famous instance of this problem is finding citation links between research outputs. Lately, another instance has been drawing more and more attention: linking research outputs with grants used as their funding source. How can this be done and how many such links can we observe?

Time to put the “R” back in “R&D”

It is time to put the ‘R’ back into R&D.

The Crossref R&D team was originally created to focus on the kinds of research projects that have allowed Crossref to make transformational technology changes, launch innovative new services, and engage with entirely new constituencies. Some Illustrious projects that had their origins in the R&D group include:

  • DOI Content Negotiation
  • Similarity Check (originally CrossCheck)
  • ORCID (originally Author DOIs)
  • Crossmark
  • The Open Funder Registry
  • The Crossref REST API
  • Linked Clinical Trials
  • Event Data
  • Grant registration
  • ROR

And for each project that has graduated, there have been several that have not. Some projects were simply designed to gather data. Others just didn’t generate enough interest. You are not truly experimenting if you don’t fail occasionally too.

Double trouble with DOIs

Detective Matcher stopped abruptly behind the corner of a short building, praying that his loud heartbeat doesn’t give up his presence. This missing DOI case was unlike any other before, keeping him awake for many seconds already. It took a great effort and a good amount of help from his clever assistant Fuzzy Comparison to make sense of the sparse clues provided by Miss Unstructured Reference, an elegant young lady with a shy smile, who begged him to take up this case at any cost.
