4.7 Creating CategoryScheme
A CategoryScheme groups similar objects based on shared characteristics, providing a hierarchical structure that helps classify and organise data and metadata meaningfully.
Referencing our two initial tables (Table: 4.1 and Table: 4.2), we will create a CategoryScheme using the Table Modeller option in the SDMX Constructor. The categorisation could be by topics such as ‘Unemployment Rate’ and ‘Population outside the labour force’.
- First, we will click the CategoryScheme button and enter the properties (ID: CAS_BY_TOPIC, AgencyID: DEMOLAND_NSO, Version: 1.0 and Name: Categorisation Scheme By Topic) as shown below.
