Overview
A URN is an abbreviation for Uniform Resource Name. 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 together 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 references 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 Maintainable, i.e a Code within a Codelist)
URN Namespace
The URN Namespaces are defined by SDMX, and take the following syntax:
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.
URN Identifiers
The URN Namespace identifies which type of Structure is being referenced, i.e., a Codelist, Data Structure, Concept, etc.
The subsequent properties in the URN Namespace are used to Identify the structure, starting with the Maintainable identifiers, which are:
- Agency Id
- Identifiable
- Version
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.
For structures which live nested inside others, i.e., a Category which is a number of levels deep, the nesting is part of the URN identification.
urn:sdmx:org.sdmx.infomodel.categoryscheme.Category=SDMX:STAT_SUBJECT_MATTER(1.0).DEMO_SOCIAL_STAT.HEALTH
Where the HEALTH Category is a child of the DEMO_SOCIAL_STAT Category.
