Bibliographic metadata sources

AutiHub stores bibliographic records as structured data. Some fields are imported from external metadata services, and some may come from source files supplied by project teams. This page explains where the data can come from.

External metadata services

OpenAlex is used first when a DOI is imported. It can provide titles, publication dates, authors, journal or source information, open-access information, funders, and funding or grant records when those data are available.

Crossref is used when OpenAlex does not provide a usable record. Crossref can provide DOI metadata deposited by publishers, including titles, journals, authors, licences, funders, and funding or grant numbers.

DataCite is checked when a DOI is not found through the main publication metadata services. It is especially useful for repository, dataset, preprint, and institutional records, and may include funding references.

Imported source files

When references are imported from BibTeX, AutiHub keeps selected fields from the source file. Funding fields in BibTeX are treated carefully because they are not always standardised. If a funding statement is only available as free text, AutiHub marks it with lower confidence and keeps the original source data for review.

Transparency

Reference pages show the source of funding data so readers can see whether the information came from OpenAlex, Crossref, DataCite, or BibTeX.
