The Web Interface to the Relational Registry (WIRR) is a tool to facilitate the discovery of astronomical data and services within the Virtual Observatory (VO) framework. It provides users with a web-based platform to search and access metadata about various astronomical resources, including datasets, services, and tools. WIRR operates by interfacing with the Relational Registry, which organizes resource metadata into a structured, relational database format. This structure allows for efficient querying and retrieval of information, enabling astronomers and researchers to locate resources pertinent to their scientific inquiries.
