A single aggregator over the external repositories the institution already uses. Holds metadata and permalinks; files live where they belong.
Tesara is the platform's single point of contact for external repository systems — the major external research repositories. It harvests metadata from each, proxies deposits on behalf of the researcher, normalises records into a canonical schema, and exposes the result to every other Accadema product through one API.
By design, Tesara is not a storage backend. Files continue to live in the system that is best at storing them — institutional theses, dataset repositories, the publisher's platform for the article of record. Tesara holds the persistent identifier and the normalised metadata. The applications that need the file resolve it through Tesara when they need it.
standard metadata harvesting from the major external repositories — with deduplication, identifier reconciliation and provenance tracking.
standard deposit to external repositories on behalf of the researcher — with the local application keeping only the resulting permalink.
A canonical schema with standard researcher and affiliation authorities as authority sources — so the same researcher and the same affiliation are recognisable across feeds.
Tesara is the single contract for every external repository. One aggregator, one audit trail, one place to plug in the next source.
