Custom Libraries & Metadata

Creating a Custom Library

  1. In Library, click New Library.
  2. Choose a name and description.
  3. The library is scoped to your tenant (tenant_id).

Metadata Categories

Each library supports typed metadata categories:

  • TEXT — free-form string
  • NUMBER — numeric value (Decimal)
  • SELECT — constrained option list
  • BOOLEAN — true/false toggle
  • APPARATUS — linked apparatus reference

Categories are managed via Manage Metadata Categories and validated with validate_metadata_values on write.

Library Items

Items store values in a JSONB metadata_values column. Editing is only allowed for tenant-owned items.
