More metadata for machines-citations, relations, and preprints arrive in the REST API

Over the past few months we have been adding to the metadata and functionality of our REST API, Crossref’s public machine interface for the metadata of all 90 million+ registered content items. Much of the work focused on a review and upgrade of the API’s code and architecture in order to better support its rapidly growing usage. But we have also extended the types of metadata that the API can deliver.

Using the Crossref REST API. Part 5 (with OpenCitations)

As part of our blog post series on the Crossref REST API, we talked to Silvio Peroni and David Shotton of OpenCitations (OC) about the work they’re doing, and how they’re using the Crossref REST API as part of their workflow.

Using the Crossref REST API. Part 4 (with CLA)

As a follow-up to our blog posts on the Crossref REST API we talked to the Copyright Licensing Agency (CLA) about the work they’re doing, and how they’re using the Crossref REST API as part of their workflow.

How do you deposit data citations?

Please visit Crossref’s official Data & Software Citations Deposit Guide for deposit details.

Very carefully, one at a time? However you wish.

Last year, we introduced linking publication metadata to associated data and software when registering publisher content with Crossref Linking Publications to Data and Software. This blog post follows the “whats” and “whys” with the all-important “how(s)” for depositing data and software citations. We have made the process simple and fairly straightforward: publishers deposit data & software links by adding them directly into the standard metadata deposit via relation type and/or references. This is part of the existing content registration process and requires no new workflows.

Included, registered, available: let the preprint linking commence.

We began accepting preprints as a new content type last month (in a category known as “posted content” in our XML schema). Over 1,000 records have already been registered in the first few weeks since we launched the service.

Using the Crossref REST API. Part 3 (with SHARE)

As a follow-up to our blog posts on the Crossref REST API we talked to SHARE about the work they’re doing, and how they’re employing the Crossref metadata as a piece of the puzzle.  Cynthia Hudson-Vitale from SHARE explains in more detail…

Using the Crossref Metadata API. Part 2 (with PaperHive)

We first met the team from PaperHive at SSP in June, pointed them in the direction of the Crossref Metadata API and let things progress from there. That’s the nice thing about having an API - because it’s a common and easy way for developers to access and use metadata, it makes it possible to use with lots of diverse systems and services.

So how are things going? Alexander Naydenov, PaperHive’s Co-founder gives us an update on how they’re working with the Crossref metadata:

Linking Publications to Data and Software

TL;DR Crossref and Datacite provide a service to link publications and data. The easiest way for Crossref members to participate in this is to cite data using DataCite DOIs and to include them in the references within the metadata deposit. These data citations are automatically detected. Alternatively and/or additionally, Crossref members can deposit data citations (regardless of identifier) as a relation type in the metadata. Data & software citations from both methods are freely propagated.

Using the Crossref Metadata API. Part 1 (with Authorea)

Did you know that we have a shiny, not so new, APIkicking around? If you missed Geoffrey’s post in 2014 (or don’t want a Cyndi Lauper song stuck in your head all day), the short explanation is that the Crossref Metadata API exposes the information that publishers provide Crossref when they register their content with us. And it’s not just the bibliographic metadata either-funding and licensing information, full-text links (useful for text-mining), ORCID iDs and update information (via Crossmark)-are all available, if included in the publishers’ metadata.

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.
