Description
The modernization of the Virtual Solar Observatory as the Model-View-Controller-based VSO 2.0 application continues. We present new APIs for reporting operational health and usage metrics, together with services for extracting and visualizing selected physical observables and metadata values in High Performance Computing workflows. Examples include Stokes parameters from Solar Orbiter/PHI files and exposure-time metadata from Solar Orbiter and SDO/AIA files.
We also describe provider-focused endpoints that expose available search options, sources, and instruments. Programmatic access is demonstrated through a new VSO 2.0 client for SunPy that supports Fido.search and Fido.fetch. The client uses Pydantic models to validate user requests before submitting them to VSO 2.0.
Recent additions to the VSO 2.0 Registry describe the searchable characteristics of provider holdings in greater detail, including data levels, physical observables, datasets, and file types associated with providers, sources, and instruments. Finally, we outline a new Table Access Protocol server that will provide TAP-based access to holdings discoverable through VSO 2.0.
Together, these capabilities provide finer-grained data discovery, improved operational visibility, and more flexible programmatic access, while establishing an extensible foundation for future VSO services.
