Index API

Back-end for the OHM data index — a Zotero connector that turns the curated Zotero library into the searchable index of sources behind index.openhistorymap.org.

OHM’s sources live in Zotero, tagged with ohm:* descriptors by the Zotero plugin. This API is what turns that library into a public, queryable index: it connects to Zotero, reads the curated items and their descriptors, and serves them as the searchable catalogue behind index.openhistorymap.org.

Pair it with the Index Front-End for the browser side of the same service.
