A fairer approach to waiting for deposits

If you ever see me in the checkout line at some store do not ever get in the line I’m in. It is always the absolute slowest. Crossref’s metadata system has a sort of checkout line, when members send in their data they got processed essentially in a first come first served basis. It’s called the deposit queue. We had controls to prevent anyone from monopolizing the queue and ways to jump forward in the queue but our primary goal was to give everyone a fair shot at getting processed as soon as possible.

Outreach Day DC. Next Up? You Tell Us

Rallying the community is a key Crossref role. Sometimes this means collaborating on new initiatives but it is also an ongoing process, a cornerstone of our outreach efforts. Part of rallying the community is bringing people together, literally, in a series of outreach days around the globe. It means we encourage dialog with us and among members and non-publisher affiliates. We want to hear from the community and we hope to facilitate conversations in it.

Linked Clinical Trials initiative gathers momentum

We now have linked clinical trials deposits coming in from five publishers: BioMedCentral, BMJ, Elsevier, National Institute for Health Research and PLOS. It’s still a relatively small pool of metadata - around 4000 DOIs with associated clinical trial numbers - but we’re delighted to see that “threads” of publications are already starting to form. If you look at this article in The Lancet and click on the Crossmark button you will see that in the Clinical Trials section there are links to three other articles reporting on the same trial: two from the American Heart Journal and one from BMJ’s Heart.

Distributing references via Crossref

Known unknowns If you follow this blog, you are going to notice a theme over the coming months- Crossref supports the deposit and distribution of a lot more kinds of metadata than people usually realise. We are in the process of completely revamping our web site, help documentation, and marketing to better promote our metadata distribution capabilities, but in the mean time we think it would be useful highlight one of our most under-promoted functions- the ability to distribute references via Crossref.

Beyond the DOI to richer metadata

In DOIsMetadata

The act of registering a DOI (Digital Object Identifier) for scholarly content is sometimes conflated with the notion of conferring a seal of approval or other mark of good quality upon an item of content. This is a fundamental misunderstanding. A DOI is a tool, not a badge of honor. The presence of a Crossref DOI on content sends a signal that: The owner of the content would like to be formally cited if the content is used in a scholarly context.

Getting Started with Crossref DOIs, courtesy of Scholastica

I had a great chat with Danielle Padula of Scholastica, a journals platform with an integrated peer-review process that was founded in 2011. We talked about how journals get started with Crossref, and she turned our conversation into a blog post that describes the steps to begin registering content and depositing metadata with us. Since the result is a really useful description of our new member on-boarding process, I want to share it with you here as well.

Python and Ruby Libraries for accessing the Crossref API

I’m a co-founder with rOpenSci, a non-profit that focuses on making software to facilitate reproducible and open science. Back in 2013 we started to make an R client working with various Crossref web services. I was lucky enough to attend last year’s Crossref annual meeting in Boston, and gave one talk on details of the programmatic clients, and another higher level talk on text mining and use of metadata for research.

Event Data: open for your interpretation

What happens to a research work outside of the formal literature? That’s what Event Data will aim to answer when the service launches later this year. Following the successful DOI Event Tracker pilot in Spring 2014, development has been underway to build our new service, newly re-named Crossref Event Data. It’s an open data service that registers online activity (specifically, events) associated with Crossref metadata. Event Data will collect and store a record of any activity surrounding a research work from a defined set of web sources.

Linking clinical trials = enriched metadata and increased transparency

We will shortly be adding a new feature to Crossmark. In a section called “Clinical Trials” we will be using new metadata fields to link together all of the publications we know about that reference a particular clinical trial. Most medical journals make clinical trial registration a prerequisite for publication. Trials should be registered with one of the fifteen WHO-approved public trial registries , or with clinicaltrials.gov which is run by the US National Library of Medicine.

Crossref & the Art of Cartography: an Open Map for Scholarly Communications

 

In the 2015 Crossref Annual Meeting, I introduced a metaphor for the work that we do at Crossref. I re-present it here for broader discussion as this narrative continues to play a guiding role in the development of products and services this year.

Metadata enable connections

Cartography BorgesAt Crossref, we make research outputs easy to find, cite, link, and assess through DOIs. Publishers register their publications and deposit metadata through a variety of channels (XML, CSV, PDF, manual entry), which we process and transform into Crossref XML for inclusion into our corpus. This data infrastructure which makes possible scholarly communications without restrictions on publisher, subject area, geography, etc. is far more than a reference list, index or directory.
