Exploring Schema Repositories with Schemr

Summary: Schemr is a schema search engine over metadata repositories, enabling keyword and example-based (schema fragment) queries. A novel hybrid ranking fuses text search with structural schema matching via a structurally-aware score, with a GUI supporting pan/zoom, drill-in, and layout-driven visualization.
