retriever

is an Aggregator.

It is part of the Translator collection.

Retriever is an NCATS Biomedical Data Translator Knowledge Provider (infores:retriever) from the DOGSURF team that answers TRAPI queries directly against two data tiers: a Tier 0 graph engine (Gandalf) and a Tier 1 Elasticsearch index built from the merged Translator KG. It serves as an intermediary for the Shepherd reasoning system, deduplicating subqueries, caching results and centralizing identifier normalization.
