On these pages you will find documentation, samples and systems that have already implemented SDMX-HD.
The adoption of the ISO/TS 17369:2005 Statistical Data and Metadata Exchange standard (SDMX) standard by the UN for aggregate data exchange will contribute to efforts to promote computer system interoperability and data use. The SDMX-HD (Health Domain) is the WHO implementation of the SDMX standard which is implemented in the WHO Indicator and Measurement Registry (IMR), a facility for harmonizing, managing, and publishing computer-readable indicator definitions. The standard relates to other data exchange standards in the following way:
The SDMX-HD is intended to become part of countries' Health Information System (HIS) and M&E infrastructure strengthening strategy, facilitating seamless flow of information from facility to district, national, and international levels in the absence of well-developed Internet access.
The SDMX standard describes statistical data and metadata through a data structure definition (DSD), which defines concepts that define dimensions, attributes, codelists and other artifacts necessary to describe the structure and meaning of data. A parallel metadata structure definition(MSD) describes metadata associated with data at observation, series, group, and dataset levels.
With the SDMX-HD, these structures define metadata concepts recommended in international standards and programmes, creating a message that will satisfy a majority of PHI requirements with common and programme-specific needs.
