FAIR² Access Governance Documentation

Level 0 – Embargoed Access

This document provides the case scenario matrix for Level‑0 access, together with metadata examples for each variant.
It follows the FAIR² interpretation:

Level 0 – Embargoed Access
Metadata is publicly visible, but the dataset itself is under embargo until a specified release date.
Users may discover and cite the dataset but may not download or redistribute the data before the embargo expires.
The dataset will be released under ODC‑BY 1.0 and the FAIR² sDUA on the embargo date.

1. Overview of Level 0 (Embargoed Access)

Level 0 supports:

Early discoverability (metadata open)
Early citation without data exposure
Strict non‑access to raw data until release date
Machine‑readable embargo timers
Optional pre‑registration of AI‑related constraints that will apply after embargo release

FAIR² models Level 0 using these constraint axes:

identity: none
environment: none (no access allowed)
communityGovernance: none (or minimal consultation if specified)
aiTraining: irrelevant until release, but may be preset
exportRestriction: irrelevant until release
distribution‑level availability: metadata only, no file access

2. Level 0 Case Scenario Matrix

Variant	Description	metadata	data access	governance	embargo expiration	notes
0.1	Simple embargoed dataset	public	none	none	fixed date	Standard case
0.2	Embargoed + planned AI training rules	public	none	none	fixed date	AI rules declared in advance
0.3	Embargoed until publication (no fixed date)	public	none	none	“upon publication”	Common for manuscripts
0.4	Embargoed + community consultation required after release	public	none	consultationRequired	fixed date	CARE obligations start after release
0.5	Embargoed + partial pre‑release (metadata + derived summaries only)	public	derived-only	none	fixed date	Summaries allowed pre‑release
