=Overview=
A URN is an abbreviation for [https://en.wikipedia.org/wiki/Uniform_Resource_Name '''U'''niform '''R'''esource '''N'''ame]. The URN, as used by the SDMX specification, is a globally unique identifier to any [[Identifiable]] SDMX Structure.

The URN is used as a mechanism to link structures togeather without having to know the exact location of the structure, this is how the URN differs from a URL, the former provides a long lasting referneces which is agnostic to location, the latter provides a precise location of where to obtain the resource.

=Structure of a SDMX URN=
A URN is made up of 2 to 3 parts, depending on the type of structure being referenced.
# Namespace
# Reference to the [[Maintainable]] Structure
# Reference to the [[Identifiable]] Structure (if the URN is referencing a Structure within a Maintianable, i.e a Code within a Codelist)

==URN Namespace==
The URN Namespaces are defined by SDMX, and take the following syntax:

[[File:URN Namespace.png|none]]

The prefix for all SDMX Structural Metadata is '''urn:sdmx:org.sdmx.infomodel'''. The Package and Class are used to represent the type of structure being referenced. The following table shows a comprehensive list of packages and classes assigned.

 If the structure is not a [[Maintainable]] structure, but instead lives inside one, i.e a Code which lives inside a Codelist or a Dimension which lives inside a Data Structure, then the remainder of the URN is used to identify the structure inside the Maintainable parent.
