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.
It is crucial to distinguish between topics and specific indicators within those topics. For instance, in this user manual, we have used two indicators as examples: ‘Unemployment Rate by sex and region’ and ‘Population outside the labour force by sex and age group.’ Although these indicators focus on different aspects, they both fall under the broader topic of the Labour force.
Referencing our two initial tables (Table: 4.1 and Table: 4.2), we will create a CategoryScheme in the SDMX Constructor. The categorisation would be by the topic ‘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.
