inventory
DASDAE Inventory: DASCore’s metadata model for DFOS observing systems.
The inventory extends the StationXML concept with first-class support for fiber-optic arrays. It describes the physical optical path (fiber, connectors, splices), the geometry, coupling, and label tracks along optical distance, and the interrogator configurations (acquisitions) that produced patches. Patches carry a acquisition_key (network.fiber_array.location.acquisition) which, together with time, resolves against an inventory.
Each object documents the rules it enforces.
Functions
