Grants markup guide
All metadata records and identifiers registered with Crossref are submitted as XML formatted using our metadata input schema. Unlike other objects registered with Crossref, grants have their own grant-specific input schema. Version 0.1.1 of our Grants schema is available in our GitLab schema repository, as is a complete XML example.
Please note: as of version 0.1.1 a version attribute is required in the <doi_batch> schema declaration, for example:
<doi_batch xmlns="http://0-www-crossref-org.libus.csd.mu.edu/grant_id/0.1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://0-www-crossref-org.libus.csd.mu.edu/grant_id/0.1.1 http://0-www-crossref-org.libus.csd.mu.edu/schemas/grant_id0.1.1.xsd" version="0.1.1">
Members currently using version 0.0.1 do not need to provide a version number.
Grant metadata by default includes a single or multiple projects. Multiple projects may be applied to a single grant but the DOI registered is applied at the grant level. Multiple grants may be included in a single XML file.
The metadata within each project includes basics like titles, descriptions, and investigator information (including affiliations), funding information such as funder names and identifiers from the Funder Registry, as well as information about funding types and amounts.
When registering a grant:
- you must include required project information (a project title, a funder name and identifier, and a funding type) as well as your internal grant or award number
- you should include a project description, language information, investigator details including ORCID IDs, ROR IDs within affiliations, and investigator country code; award amounts/currency, and project start and end dates and/or an award date (note that project or grant start/end dates are used to calculate current vs. backfile content registration fees).
- you may include multiple titles and descriptions as well as language information; a funding scheme, and planned project start and end dates.
Project: Project metadata includes titles and descriptions (abstracts). Both can be supplied multiple times to capture information in different languages.
