Legacy Identifier Mapping

Earlier iSHARE Framework versions used short numeric identifiers (0000, 0001, …) to reference licenses in delegation evidence. From Framework v3.0 onwards, the canonical license identifier is a fully-qualified URL (e.g. https://licenses.ishare.eu/general-unrestricted/1.0).

This page defines the canonical mapping from every recognised legacy identifier — in both bare and namespaced form — to its v3.0 canonical URL, and the timeline for the transition.

Mapping table

Both the bare form (0001) and the namespaced form (ISHARE.0001) MUST be treated as equivalent and MUST map to the same canonical URL.

Legacy identifier (bare)	Legacy identifier (namespaced)	Canonical URL
0000	ISHARE.0000	https://licenses.ishare.eu/general-unrestricted/1.0
0001	ISHARE.0001	https://licenses.ishare.eu/general-resharing-with-adhering-parties/1.0
0002	ISHARE.0002	https://licenses.ishare.eu/general-internal-use/1.0
0003	ISHARE.0003	https://licenses.ishare.eu/general-non-commercial-use/1.0
0004	ISHARE.0004	https://licenses.ishare.eu/general-enrich-with-own-data/1.0
0005	ISHARE.0005	https://licenses.ishare.eu/general-enrich-with-others-data/1.0
0008	ISHARE.0008	https://licenses.ishare.eu/general-use-to-service-entitled-party/1.0
9999	ISHARE.9999	https://licenses.ishare.eu/general-determined-between-parties/1.0

Gaps and licenses without a legacy form

• 0006 and 0007 were never assigned in the legacy scheme.
• general-internal-use-insights and general-enrich-with-third-party-generated-data are v3.0 additions and have no legacy numeric form. They MUST be referenced by canonical URL only.
• All certification, country, and industry licenses have no legacy numeric form. They MUST be referenced by canonical URL only.
