inventory_loader

module of dascore.core

source

Load a DASDAE inventory from an authoring directory.

YAML or JSON files hold model objects, while CSV files hold tabular track data. <name>.csv fills the declared model’s <name> attribute. Reserved path directories address optical-path epochs; each location code forms a lineage whose epochs end when their successors begin.

Each object file declares its type, its container verifies that type, its filename determines identity, and the top-level inventory.yaml determines the format version. Facts repeated inside a file must agree with its address.

Malformed entries that resemble format members raise errors; unrelated files are ignored. Columns beginning with an underscore are also ignored.
