The Ordnung Data Schema (ODS) defines a standardized field schema for semantic data within the Ordnung Name System. It provides common metadata conventions while remaining optional and fully extensible, similar in purpose to JSON-LD contexts for Linked Data.

Overview

ODS establishes naming conventions for common metadata fields, enabling interoperability between different ONS deployments while preserving flexibility.

Design philosophy

• Standardized but optional
• Domain-agnostic
• Intentionally minimal
• Extensible

Standard fields

Field	Format	Description
_summary	Text	Brief description of the entity
_tag	Comma-separated	Keywords and categories
_rel	URI list	Relations and links to other entities
_meta	Key-value pairs	Arbitrary metadata
_hash	Hash string	Integrity hash of content
_updated	ISO 8601	Last update timestamp
