Metadata for different purposes

Many systems and organizations use our metadata to help credit and cite works, report impact of funding, track outcomes and activity, and more. This rich global network of information about research relies on members depositing, maintaining, and updating their metadata with Crossref. Different types of metadata are used for different purposes, such as:

Metadata for discoverability

Metadata helps people and systems identify the right resources for their needs. Registering content with us makes it possible for content to be found and used. The following metadata elements are particularly useful for discoverability:

  • Basic bibliographic metadata such as title, publication date, contributor name and affiliation(s)
  • ORCID iD, funder ID, award number
  • Abstracts
  • References
  • Links to preprints
  • Full-text links (for text and data mining)
  • License URLs (for text and data mining)

Metadata for research and editorial integrity

Our metadata helps provide signals about the integrity of the research and publishing process, for example:

  • Updates (such as corrections, retractions, updates, expressions of concern)
  • Peer review reports, history, type, assets
  • Funding data (conflict of interest)
  • ORCID iDs (authors)
  • Affiliation (authors)
  • License data (full-text, abstract)
  • Clinical trials

Metadata for reproducibility

Researchers need to be able to build upon each others' work. Verifying and reproducing the results from earlier work is helped by metadata such as:

  • Links to data and datasets
  • Links to protocols and methods
  • Links to clinical trial registry, trial number
  • Updates (such as corrections, retractions, updates, expressions of concern)
  • Funding data (conflict of interest), ORCID iDs (for people, such as authors, reviewers, editors)
  • License URLs
  • Full-text URLs
  • Links to peer review reports
  • Links to versions

Metadata for reporting and assessment

Reporting and assessment may be carried out by a variety of organizations, including universities and funders in order to:

  • show the accountability and benefits of public investment,
  • provide benchmarking information,
  • demonstrate compliance with funder mandates, and,
  • decide what research to fund.

The following metadata elements are useful for reporting and assessment:

  • ROR ID (affiliation)
  • ORCID iD, funder ID, grant ID, award number
  • Abstracts
  • References
  • Peer review reports
  • Links to preprints
  • Links to conference papers and posters
  • License URLs (for text and data mining)
