SDMX (Statistical Data and Metadata Exchange)
SDMX is a shared standard, not a data source. It was created by seven international bodies (the BIS, ECB, Eurostat, IMF, OECD, UN, and World Bank) to make it easier to exchange and share statistical data and metadata between organisations that would otherwise each invent their own format.
It matters for RAG because many of the statistical agencies in this category serve their data through SDMX-based APIs. If you are ingesting figures from several agencies at once, understanding the standard lets you write one parser rather than a different one for each source, and read the metadata that explains what each series actually measures.
