A graph-based data cataloging system, product and method that structures expert knowledge and statistically driven data analytics into a system-based framework for finding and relating enhanced metadata on subject-relevant, curated datasets from disparate, externally held data sources is shown. Displayed across a knowledge graph of nodes of datasets linked by their metadata attributes, the system simplifies the search and retrieval of multiple datasets of relevance to a user's technical, content, and resource-driven needs.
