--=== 5.2.7 Registry Behaviour ===
++===== {{id name="_Toc90801"/}}5.2.7 Registry Behaviour =====
  The following table defines the behaviour of the SDMX Registry for the various Registry Interface messages. It should be noted, though, that as of SDMX 3.0, an extended versioning scheme newly including semantic versioning is foreseen for all Maintainable Artefacts. Moreover, while the old versioning scheme is allowed, given there is no more a "final" flag, there is no way guaranteeing the consistency across version of a Maintainable, unless semantic versioning is used.
  Given the above, the behaviour described in the following table concerns either draft Artefacts using semantic versioning or any Artefacts using the old versioning scheme. Nevertheless, in the case of semantic versioning the registry must respect the versioning rules when performing the actions below. For example, it is not possible to replace a non-draft Artefact that follows semantic versioning, unless a newer version is introduced according to the semantic versioning rules. Furthermore, even when draft Artefacts are submitted, the registry has to verify semantic versioning is respected against the previous non-draft versions. It is worth noting that the rules for semantic versioning and replacing or maintaining semantically versioned Artefacts applies to externally shared Artefacts. This means that any system may internally perform any change within a version of an Artefact, until the latter is shared outside of that system or becomes public. Then (as also explained in the SDMX Standards Section 6 “Technical Notes”) the Artefacts must adhere to the Semantic Versioning rules.

++**6.2.2.1 Introduction**
  To provide interoperability between SDMX Registry/Repositories in a distributed network environment, it is important to have a scheme for uniquely identifying (and thus accessing) all first-class (Identifiable) SDMX-IM objects. Most of these unique identifiers are composite (containing maintenance agency, or parent object identifiers), and there is a need to be able to construct a unique reference as a single string. This is achieved by having a globally unique identifier called a universal resource name (URN) which is generated from the actual identification components in the SDMX-RR APIs. In other words, the URN for any Identifiable Artefact is constructed from its component identifiers (agency, id, version etc.).
