The National Digital Forecast Database (NDFD) Extensible Markup Language (XML) is a service providing the public, government agencies, and commercial enterprises with data from the National Weather Service’s (NWS) digital forecast database.   This service, which is defined in a Service Description Document, provides NWS customers and partners the ability to request NDFD data over the internet and receive the information back in an XML format.  It is a widely popular service (roughly 100 million hits per day).  However, DWML is not an Open Geospatial Consortium (OGC)-compliant service.  The Timeseries Markup Language (TSML) will be the OGC-compliant version of DWML.  Both SOAP and REST-based version of TSML have been set up.
