Fetchers

Fetchers must 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.

Crossref fetcher must use polite pool when email is configured

req~fetchers.crossref-polite-pool~1

Needs: impl

Identifier fetchers must retry rate-limited requests using exponential backoff

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

User can view journal information from public metadata sources

feat~fetchers.journal-information~1

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

Needs: impl

XML importers and fetchers must disable external entity resolution

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.

User can create entry from arbitrary URL

feat~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

ScholarAPI fetcher must download full text when available

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 must run as background task

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

User can 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

User can search German National Library catalog

feat~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
