This year, metadata development is one of our key priorities and we’re making a start with the release of version 5.4.0 of our input schema with some long-awaited changes. This is the first in what will be a series of metadata schema updates.
What is in this update?
Publication typing for citations
This is fairly simple; we’ve added a ‘type’ attribute to the citations members supply. This means you can identify a journal article citation as a journal article, but more importantly, you can identify a dataset, software, blog post, or other citation that may not have an identifier assigned to it. This makes it easier for the many thousands of metadata users to connect these citations to identifiers. We know many publishers, particularly journal publishers, do collect this information already and will consider making this change to deposit citation types with their records.
Every year we release metadata for the full corpus of records registered with us, which can be downloaded for free in a single compressed file. This is one way in which we fulfil our mission to make metadata freely and widely available. By including the metadata of over 165 million research outputs from over 20,000 members worldwide and making them available in a standard format, we streamline access to metadata about scholarly objects such as journal articles, books, conference papers, preprints, research grants, standards, datasets, reports, blogs, and more.
Today, we’re delighted to let you know that Crossref members can now use ROR IDs to identify funders in any place where you currently use Funder IDs in your metadata. Funder IDs remain available, but this change allows publishers, service providers, and funders to streamline workflows and introduce efficiencies by using a single open identifier for both researcher affiliations and funding organizations.
As you probably know, the Research Organization Registry (ROR) is a global, community-led, carefully curated registry of open persistent identifiers for research organisations, including funding organisations. It’s a joint initiative led by the California Digital Library, Datacite and Crossref launched in 2019 that fulfills the long-standing need for an open organisation identifier.
We began our Global Equitable Membership (GEM) Program to provide greater membership equitability and accessibility to organizations in the world’s least economically advantaged countries. Eligibility for the program is based on a member’s country; our list of countries is predominantly based on the International Development Association (IDA). Eligible members pay no membership or content registration fees. The list undergoes periodic reviews, as countries may be added or removed over time as economic situations change.
Publishers, researchers, funders, institutions and technology providers are all interested in better understanding how scholarly research is used. Scholarly content has always been discussed by scholars outside the formal literature and by others beyond the academic community. We need a way to monitor and distribute this valuable information.
The Crossref DOI Event Tracker (DET)
To meet this need, Crossref will be introducing a new service that tracks activity surrounding a research work from potentially any web source where an event is associated with a DOI. Following a successful pilot run started Spring 2014, the service has been approved to move toward production and is expected to launch in 2016. Any party wishing to join this phase is welcome to contact Jennifer Lin. The DOI Event Tracker (DET) registers a wide variety of events such as bookmarks, comments, social shares, citations, and links to other research entities, from a growing list of online sources. DET aggregates them, and stores and delivers the data in many ways.
Open, portable, and licensed for maximum reuse
Crossref has long served as the citation linking and metadata infrastructure provider for scholarly communication; the new DOI Event Tracker is a natural next step, providing a practical solution as a resource for the whole community. The tracker offers the following features:
Data on event activity across a common pool of online channels.
Near real-time alerting for select sources with push notifications to the system.
Cross-publisher monitoring to enable benchmarking and provide context to the data.
Common format for normalizing data results across the diverse set of sources via modern REST API.
Secure and regularly refreshed backups of critical data for long term data preservation.
Transparency of data collection so as to ensure auditable, replicable, and trustworthy results.
Query-initiated retrieval or real-time alerts when an event of interest occurs.
CC-0 license for open and flexible propagation of data.
A number of platforms are already confirmed and more parties are welcomed at any stage. So far we have confirmation to track DOI events on the following platforms:
[table id=1 /]
This set of sources reflects our initial focus on parties willing to allow their data to be redistributed in the common pool. Efforts are underway to expand the source list to include Twitter and MyScienceWork, among others. Publishers can also act as sources by publishing and distributing DOI event data via the DET when an event occurs on its platform (for example, when a PDF is downloaded, or when a comment mentions a DOI in a locally hosted discussion forum, etc.). This would make local DOI activity globally available to funders, researchers, institutions, etc.
DET provides benefits of scale and ease of access as a central point for collecting and propagating data to the community. As a single point of access, it overcomes the business and technical hurdles that are a part of managing multiple online sources where scholarly activity occurs, in a rapidly changing landscape of online channels. This resource covers content across publishers and serves as a strong foundation to support the development of tools and services by any party. DET users will always be able to combine the DET data with those individually collected via negotiated or paid access. DET remains a utility separate from any value-added amenities, such as analytics, presentation, and reporting.
DET Service-Level Agreement
For those who seek the highest level of service and a more flexible range of access options, Crossref will provide a Service-Level Agreement (SLA) service for the DOI Event Tracker. The DET SLA includes the following additional features on top of the common data offering:
Access to the complete suite of sources, which includes restricted and/or paid sources in addition to common data, providing the fullest picture of DOI usage activity possible.
Guaranteed uptime and response time to the latest raw data on the aggregate activity surrounding a DOI.
Guaranteed support response time to questions and issues surrounding data and data delivery.
Flexible data access options: on-demand real time data access and scheduled bulk downloads for processing batch analytics.
Optimum retrieval rates and accelerated delivery speeds with the dedicated SLA API.
Access to a webhook API for events of interest as an alternative to polling DET.
Standardized and enhanced linkback service for the difficult-to-track, grey literature.
The DET SLA service has a simple, value-based pricing model based on subscriber size. Register your interest in Crossref’s DOI Event Tracker and the DET SLA service if you would like stay informed of the upcoming launch. Please contact Jennifer Lin for more information.
