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 [[wp:JSON-LD|JSON-LD]] contexts for [[wp:Linked_data|Linked Data]].<br />
<br />
== Overview ==<br />
<br />
ODS establishes naming conventions for common metadata fields, enabling interoperability between different ONS deployments while preserving flexibility.<br />
<br />
=== Design philosophy ===<br />
<br />
* Standardized but optional<br />
* Domain-agnostic<br />
* Intentionally minimal<br />
* Extensible<br />
<br />
== Standard fields ==<br />
<br />
{| class="wikitable"<br />
|-<br />
! Field !! Format !! Description<br />
|-<br />
| <code>_summary</code> || Text || Brief description of the entity<br />
|-<br />
| <code>_tag</code> || Comma-separated || Keywords and categories<br />
|-<br />
| <code>_rel</code> || URI list || Relations and links to other entities<br />
|-<br />
| <code>_meta</code> || Key-value pairs || Arbitrary metadata<br />
|-<br />
| <code>_hash</code> || Hash string || Integrity hash of content<br />
|-<br />
| <code>_updated</code> || ISO 8601 || Last update timestamp<br />
|}<br />
<br />
== Usage examples ==<br />
<br />
{{Code example<br />
| language = text<br />
| caption = ODS-formatted entry<br />
| code = project-alpha.projects.example.com. CH TXT "_summary=AI research project focused on agent coordination"<br />
