Statistical Data and Metadata eXchange (SDMX) for the Python data ecosystem

pandaSDMX 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.

pandaSDMX can be used to:

  • explore the data available from over 20 data providers such as the World Bank, BIS, ILO, ECB, Eurostat, OECD, UNICEF and United Nations;

  • parse data and metadata in SDMX-ML (XML) or SDMX-JSON formats—either:

    • from local and remote files, or

    • retrieved from pandasdmx 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; See also the companion project `intake_sdmx <>`__, a plugin for the intake data acquisition and distribution framework;

  • apply the SDMX Information Model to your own data;

  • validate SDMX files against the official XML schemas;

…and much more.

Get started

Assuming a working copy of Python 3.9 or higher is installed on your system, you can get pandaSDMX either by typing from the command prompt:

$ pip install pandasdmx

or from a conda environment:

$ conda install pandasdmx -c conda-forge

Next, look at a usage example in only 10 lines of code. Then dive into the longer, narrative walkthrough and finally peruse the more advanced chapters as needed.

Bear in mind that SDMX was designed to be flexible enough to accommodate almost any data. This also means it is complex, with many abstract concepts for describing data, metadata, and their relationships. These are called the “SDMX Information Model” (IM).

This documentation gently explains the functionality provided by pandaSDMX itself enabling you to make the best use of all supported data sources. A decent understanding of the IM is conveyed in passing. However, if you got hooked, follow the list of resources and references, or read the API documentation and implementation notes for the pandasdmx.model and pandasdmx.message modules that implement the IM.
