Fetchers

Respect provider request limits

req~fetchers.rate-limiting~1

Fetchers with a documented request limit throttle requests across all fetcher instances. Limits expressed as requests per time interval are converted consistently to requests per second.

Needs: impl

Use Crossref’s polite pool

req~fetchers.crossref-polite-pool~1

When an email address is configured for Crossref, requests include it in the mailto parameter to use Crossref’s polite pool.

Needs: impl

Retry identifier lookups after rate limiting

req~fetchers.identifier-rate-limit-retries~1

Identifier fetchers retry a request rejected with HTTP 429 using bounded exponential backoff, while preserving all other client errors.

Needs: impl

Retrieve journal information from public sources

req~fetchers.journal-information~1

The journal-information popup retrieves journal identity information and metrics directly from public metadata providers.

Needs: impl

Reject external entities in XML responses

req~fetchers.xml-xxe-prevention~1

MODS and Medline XML imports and PICA, MARC, ISIDORE, and arXiv XML fetcher responses disable DTD processing so that external entities cannot be resolved.

Create an entry from an arbitrary URL

req~fetchers.generic-url~1

The user can enter an arbitrary URL to create an entry from it. JabRef tries URL-based fetchers first; if none handles the URL, it falls back to creating a @Misc entry with the plain URL, using the linked page’s title when it can be reached (falling back to the URL itself otherwise) and recording the date the link was added (urldate).

Needs: impl

Download full text from ScholarAPI

req~fetchers.scholarapi-fulltext~1

For entries that contain a ScholarAPI identifier and have a PDF available, JabRef discovers the ScholarAPI PDF endpoint and uses the configured ScholarAPI API key to download the full text.

Full text search runs in the background

req~fetchers.fulltext-background-search~1

The search for full text documents runs as a background task shown in the status bar with progress and a cancel option, so JabRef stays usable while it runs. Its results are applied to the library the entries were selected in, and are discarded if that library was closed meanwhile.

Needs: impl

Fetch entry by Software Heritage identifier (SWHID)

feat~fetchers.swhid~1

The user can look up and import bibliography entries by providing a Software Heritage identifier (SWHID).

Needs: impl

Search the German National Library (DNB)

req~fetchers.dnb-search~1

The user can search the German National Library (DNB) catalog as a search-based fetcher, retrieving matching bibliographic entries by title, author, or other search terms.

Needs: impl

Look up entries in the German National Library by ISBN

req~fetchers.dnb-isbn-lookup~1

The user can retrieve a bibliographic entry from the German National Library (DNB) by providing an ISBN.
