Object Metadata

Object Metadata provides a structured way to store and manage additional information about objects beyond their core data.

Overview

The metadata system supports:

Field	Type	Description	Purpose
uuid	string	Unique universal identifier	Globally unique object identification
uri	string	Uniform Resource Identifier	Unique addressable location
version	string	Semantic version number	Track object versions
register	string	Register identifier	Object categorization/grouping
schema	string	Schema identifier	Data validation reference
textRepresentation	text	Text representation of object	Search and display optimization
locked	json	Lock information object	Concurrent access control
owner	string	Nextcloud user identifier	Object ownership
authorization	json	Authorization rules	Access control configuration
updated	datetime	Last modification timestamp	Change tracking
created	datetime	Creation timestamp	Lifecycle management
folder	string	Storage folder path	File organization

Field	Type	Description	Purpose
files	json	Related file IDs	Track associated files
relations	json	Related object IDs	Track object relationships

When an object is locked, the following metadata is stored:

{ 'user': 'user_id', 'process': 'optional_process_name', 'created': 'timestamp', 'duration': 'seconds', 'expiration': 'timestamp' }
