Statistical Data and Metadata eXchange (SDMX) in Python¶
sdmx is an Apache 2.0-licensed Python library that implements SDMX 2.1 (ISO 17369:2013), a format for exchange of statistical data and metadata used by national statistical agencies, central banks, and international organisations.
sdmx can be used to:
explore the data available from data providers such as the World Bank, International Monetary Fund, Eurostat, OECD, and United Nations;
parse data and metadata in SDMX-ML (XML) or SDMX-JSON formats—either:
from local files, or
retrieved from SDMX web services, with query validation and caching;
convert data and metadata into pandas objects, for use with the analysis, plotting, and other tools in the Python data science ecosystem;
apply the SDMX Information Model to your own data;
…and much more.
SDMX was designed to be flexible enough to accommodate almost any data. To do this, it includes a large number of abstract concepts for describing data, metadata, and their relationships. These are collectively called the “SDMX Information Model” (IM).
This documentation does not repeat full descriptions of SDMX, the IM, or SDMX web services; it focuses on the Python implementation in
Detailed knowledge of the IM is not needed to use
sdmx; see a
usage example in only 10 lines of code, and then the longer, narrative walkthrough.
To learn about SDMX in more detail, use the list of resources and references, or read the API documentation and implementation notes for the
sdmx.message modules that fully implement the IM in Python.
