The Research Resource Identification, #RRID, Initiative is designed to help researchers cite the key biological resources used to produce their scientific findings. We know that researchers do not always write all of the excruciating details of their experimental methods sections, sometimes even if they want to, they are turned away by page limits or by convention. We are here to support authors by making some parts of their methods section more transparent and rigorous by allowing them to easily access millions of "Key Biological Resources" on our website and giving authors an unambiguous proper citation format. This format is echoed on many company and project websites around the world.

Thoth is a metadata management and distribution platform and service designed to address the challenges faced by small- to medium-sized publishers in getting open access works into the book supply chain.

OAI-PMH is a set of six verbs or services that are invoked within HTTP.

The IGSN is a persistent unique identifier for physical samples and specimens that eliminates the problems associated with the ambiguous naming of samples. The IGSN registration service helps discover, access, and share samples, ensure preservation of and access to sample data, aid identification of samples in the literature, and advance the exchange of digital sample data among interoperable data systems, thus maximizing the utility of samples for research, education, and society. In 2022, IGSN and DataCite entered a strategic partnership to provide a globally recognised persistent identifier for sample identification and tracking, based on DataCite Digital Object Identifiers (DOI), that facilitates the efficient sharing of samples and their associated metadata among researchers, institutions, and databases. IGSN IDs are now based on DataCite infrastructures and registered through DataCite services.

Landing pages support humans that interact with scholarly objects on the web, providing descriptive metadata and links to content. These pages are not optimized for use by machine agents that navigate the scholarly web. For example, how can a robot determine which links on the myriad of landing pages lead to content and which to metadata? FAIR Signposting caters to machine agents by providing this information, and more, in a standards-based way. It contributes to FAIR's Findable, Accessible, and Reusable by uniformly conveying to machines what the persistent identifier of a scholarly object is, where its landing page is, where and what its content is, where metadata that describes it is, and what the persistent identifier of its author is. It conveys this by means of a limited set of typed web links that have web locations (HTTP URIs) as their target.

The Keepers Registry acts as a global monitor on the archiving arrangements for continuing resources including e-serials.

On registration, the PKP PN determines if the journal meets the minimum inclusion requirements. The PKP PN relies on OJS export tools to generate content for preservation. This content is automatically deposited into the PKP PN by the OJS PKP PN plugin and does not require manual intervention from journal editors or staff. The PKP PN provides free online access to restored content following a "trigger event," when a journal has ceased to exist online and preserved content is used for restoration.

The FAIR Interoperability Catalogue - FAIRiCat - cen be used by repositories to uniformly advertise the interoperability affordances they provide. Interoperability affordances can encompass the entire collection of objects managed by a repository (e.g. OAI-PMH, APIs) or only manifest when interacting with an object managed by the repository (e.g. FAIR Signposting, Dublin Core). FAIRiCats can be used in automatic processes by clients that are looking for specific approaches to interoperate with a repository, e.g. via OAI-PMH, SPARQL, Sitemaps, Linked Data Notifications. FAIRiCats can also be used manually as a way to obtain a quick overview of the interoperability characteristics of a repository.

Our community includes tens of thousands of organisations and systems in over 160 countries. Around 20,000 organisations are members so that they can create identifiers for metadata records that describe and locate their research. The records describe articles, book chapters, preprints, grants, and all kinds of digital or even physical objects relating to scholarly and professional research. Crossref members share the records through Crossref so that they don’t have to duplicate the information for the thousands who consume and use it downstream throughout the global research ecosystem.

The focus here is on the part of the Crossref infrastructure that facilitates the open and accessible retrieval of these metadata records, numbering over 160 million today.

Anyone can access to use these records without restriction, either through our search tool, search.crossref.org, or our REST API, api.crossref.org. There are no fees to use the metadata, but people who really rely on it may sign up for Metadata 'Plus', which offers greater predictability and higher rate limits.

People retrieving Crossref metadata need it for all sorts of reasons, including metaresearch (researchers studying research itself, such as through bibliometric analyses), publishing trends (such as finding works from an individual author or reviewer), or incorporation into specific databases (such as for discovery and search or in subject-specific repositories), and many more detailed use cases.
