- LocationSchema: Defines the structure and metadata for a category of Locations in Benchling's inventory system. A LocationSchema specifies schema field definitions for capturing location-specific data (e.g., temperature range, access restrictions) and an optional Registry association with display ID prefix. LocationSchemas categorize different types of storage areas such as "Freezer", "Refrigerator", "Shelf", or "Room". Locations conforming to a schema inherit its field definitions, allowing consistent metadata capture across similar storage types.
