# SPARC Datasets ## Introduction The SPARC metadata APIs are provided via an ElasticSearch endpoint. The metadata is extracted from K-Core's metadata export and processed via the FDI Lab's Foundry - a message-oriented, horizontally scalable ETL system for scientific data integration and enhancement (Ozyurt and Grethe 2018). ### References Ozyurt, I.
