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.
Last week we had a second face-to-face of the OAI-ORE (Open Archives Initiative – Object Reuse and Exchange) Technical Committee in New York, the meeting being hosted courtesy of Google. (Hence the snap here taken from the terrace of Google’s canteen with its gorgeous view of midtown Manhattan. And the food’s not too shabby either. ;~)
The document attempts to describe the problem domain - that of describing a scholarly publication as an aggregation of resources on the Web - and to put that squarely into the Web architecture context. What the initiative is seeking to provide is machine descriptions of those resources and their relationships, something that we are inclining to call “resource maps” and as underpinning we are making use of the notion of “named graphs” from ongoing semantic web research. Essentially these resource maps are machine-readable descriptions of participating resources (in a scholarly object - both core resources and related resources) and the relationships between those resources, the whole set of assertions about those resources being named (i.e. having a URI as identifier) and having provenance information attached, e.g. publisher, date of publication, version information (still under discussion). It is envisaged that these compound object descriptions may be available in a variety of serializations from a published, object-specific URL (i.e. a good old-fashioned Web address) but some honest-to-goodness XML serialization is a likely to be one of the candidates. No surprises here, then.
Below is a schematic from the paper which shows the publication of a resource map (or named graph) corresponding to the compound object which logically represents a scholarly publication. For those objects of immediate interest to Crossref these would likely be identified with DOI’s although there is no restriction in OAI-ORE on the identifier to be used - other than it be a URI.
Update: For a couple posts from some other members of the ORE TC see here (Peter Murray, OhioLINK) and here (Pete Johnston, Eduserv).
