Rich Metadata-driven Datasets
 Metadata-driven datasets for
• an SDMX registry enabled
• machine to machine
• automated data exchange
 SDMX structures help making data more discoverable
• Data Structures Definition (DSD),
• Provision Agreements, etc..
 SDMX notifications services reduce data exchange delay
between data provider and consumer
Data is more discoverable

Editor's Notes

  • #4 For hundreds of years, tables were the main way to disseminate statistical data In the early years of the internet, data came online, but still mainly in tables and other two-dimensional presentations (e.g. charts and maps) These are so popular because they are easy for humans to understand But finding the right table or chart can be tricky… Data dissemination has evolved to a point where rich, metadata-driven discovery can help users (human or machine) find and access data quickly
  • #5 As the internet developed, disseminated datasets became bigger and multidimensional These datasets were indexed in two ways: Internally, so human users could search for the variables of interest Externally, so human users could search for the right datasets The SDDS National Summary Data Page (NSDP) is an example of such an index
  • #6 Implementation of SDMX provides a standard for providing machine readable data Early SDMX versions focused on providing a structure for internal definition of datasets Dissemination mostly by bilateral exchange or posting or hosting datasets
  • #8 More than just a SDMX registry fully integrated, metadata-driven service using the SDMX standard as the foundation enhance data dissemination process building on the SDMX information model used to describe datasets by defining the dimensionality of a dataset allowable content for each of the dimensions Provision agreements are used to define which data complier or agency supplies which data, aiding discovery Registrations can drive notifications, supporting automated machine retrieval of data Human users can browse all datasets registered with SDMX Central, no matter where the SDMX data resides
  • #12 Load Data to Validate, Transform, Publish, Register and Receive SDMX notification
