AEON GP Document v1
Convention identifier: aeon.gp.document.v1
Purpose
aeon.gp.document.v1 defines a standard vocabulary for document-level metadata.
This metadata describes:
authorship
origin
lifecycle
classification
discoverability
machine handling hints
The convention applies to metadata stored inside the AEON header.
Location
Document metadata lives inside:
aeon:header
Example:
aeon:header = {
encoding = "utf-8"
mode = "strict"
convention = "aeon.gp.document.v1"
}
Metadata Container
All document metadata is stored in a document object.
aeon:header = {
encoding = "utf-8"
mode = "strict"
document = {
title = "Weather Report"
author = "Alice"
}
}
This keeps metadata separate from processing fields.
Metadata Fields
Identity
document = {
title = "Weather Report"
subject = "Daily rainfall observations"
description = "Observation notes recorded during coastal storm"
}
Fields:
| field | meaning |
|---|---|
title | document title |
subject | short topic |
description | longer description |
Authorship
document = {
author = "Alice"
contributors = ["Bob","Carol"]
}
Fields:
| field | meaning |
|---|---|
author | primary author |
contributors | additional contributors |
Copyright and Rights
document = {
copyright = "© 2026 Alice Example"
license = "CC-BY-4.0"
}
Fields:
| field | meaning |
|---|---|
copyright | copyright notice |
license | license identifier |
Document Lifecycle
document = {
created = 2026-03-08T18:00:00Z
modified = 2026-03-08T18:45:00Z
}
Fields:
| field | meaning |
|---|---|
created | creation timestamp |
modified | last modification timestamp |
Classification
document = {
labels = ["weather","storm","coastal"]
tags = ["rainfall","field-notes"]
}
Fields:
| field | meaning |
|---|---|
labels | keyword labels |
tags | alternate label field if desired |
Namespace Metadata
The ns field declares a semantic namespace for document-level labels or document identity.
document = {
ns = "aeon"
}
Namespaces qualify interpretation within a named semantic domain and reduce ambiguity between similar labels.
When namespace labels are needed on individual values, the same key may be used as binding metadata:
type@{ns="aeon"} = "document"
status@{ns="workflow"} = "approved"
kind@{ns="media"} = "image"
The ns label is descriptive only.
It does not create a schema namespace, import mechanism, or lookup rule by itself.
Privacy and Handling
document = {
privacy = "internal"
}
Example values:
| value | meaning |
|---|---|
public | openly distributable |
internal | internal use |
confidential | restricted |
private | personal |
The exact semantics may be defined by profiles.
Content Format
document = {
format = "report"
}
Examples:
report
message
dataset
contract
log
configuration
This field describes the conceptual type of document.
The format key may also be used as binding metadata when a document value carries a known representation pattern.
build@{format="semver"}:sep["."] = ^1.0.0
date@{format="ymd"}:sep["-"] = ^2026-03-07
location@{format="geo:lat,lon"}:sep[","] = ^"37.8136,144.9631"
In this form, format labels the representation pattern.
It does not require validation unless a schema, profile, processor, or another convention defines that validation.
Generation Metadata
document = {
generation = "ai-assisted"
}
Example values:
| value | meaning |
|---|---|
human | fully human written |
ai-assisted | AI helped generate |
ai-edited | AI modified |
ai-generated | fully AI generated |
This can help downstream consumers evaluate provenance.
Robot Handling
document = {
robots = "noindex"
}
Examples:
index
noindex
noai
noarchive
This mirrors common web document conventions.
Cache Hints
document = {
cache = "no-store"
}
Examples:
cache
no-cache
no-store
This field is advisory and intended for systems distributing AEON documents.
Reference Information
document = {
reference = "doc-2026-031"
}
Examples:
internal id
document reference number
archival identifier
Language Metadata
The language field identifies the natural language used in the document.
Use BCP-47 language tags.
Examples:
| Language | Tag |
|---|---|
| English | en |
| Spanish | es |
| Dutch | nl |
| French | fr |
| Australian English | en-AU |
| Belgian Dutch | nl-BE |
document = {
language = "en-AU"
}
If multiple languages appear, list the primary language first.
document = {
language = ["en","fr"]
}
Location Metadata
The location field indicates the geographic context of the document.
This may represent:
where the document was created
where the subject matter applies
geographic relevance
Location should be structured rather than a free string.
document = {
location = {
country = "AU"
region = "Victoria"
city = "Melbourne"
}
}
Using ISO-style identifiers where possible improves interoperability.
Recommended standards:
| Field | Standard |
|---|---|
| country | ISO-3166-1 |
| region/state | ISO-3166-2 |
| coordinates | WGS-84 |
If precise location matters:
document = {
location = {
country = "AU"
city = "Melbourne"
coordinates = {
lat = -37.8136
lon = 144.9631
}
}
}
Example Complete Header
aeon:header = {
encoding = "utf-8"

author = "Alice"
contributors = ["Bob"]
ns = "aeon"
language = "en-AU"
location = {
country = "AU"
region = "Victoria"
city = "Melbourne"
}
copyright = "© 2026 Alice"

}
}
Design Goals
The document convention aims to provide:
human-readable metadata
machine-readable classification
interoperability across tools
minimal structural complexity
clear separation from domain data
It is intentionally flexible so that different domains can extend or interpret the fields according to their needs.
The document convention describes the document itself. It does not model the document's domain data.
Relationship to Other Conventions
This convention complements the AEON ecosystem:
| convention | purpose |
|---|---|
aeon.gp.document.v1 | document metadata |
aeon.gp.context.v1 | contextual annotations |
aeon.gp.collection.v1 | collection semantics |
aeon.gp.measurement.v1 | measurement labels |
aeon.gp.convention.v1 | convention authoring template |
aeon.gp.security.v1 | security envelope |
aeon.gp.integrity.v1 | document hashing |
aeon.gp.signature.v1 | signatures |
aeon.gp.encryption.v1 | encryption |
Summary
aeon.gp.document.v1 provides a lightweight but structured vocabulary for describing AEON documents themselves, allowing tools and systems to understand authorship, classification, lifecycle, and handling policies without interfering with the document’s actual data structure.
