d:swarm is an open-source middleware platform designed for data integration, specifically supporting linked-data-based systems in libraries. It provides a flexible graph-based storage model for integrating heterogeneous data sources and enhances data quality through various techniques such as deduplication and semantic enrichment. The platform also features a user-friendly interface for data modeling that is accessible to non-programming librarians.
