DAS Registry: Publishing and Discovery of DAS Servers
The DAS/1 and DAS/2 specifications do not define how to publish or discover DAS sources (servers). Due to the success of DAS and the large number of sources that are spread around the world it is not easy to keep track of these. The DAS registration server at www.dasregistry.org provides a repository where people can publish and share their DAS sources with the community.
The DAS registry provdies a Web interface so users can search for available DAS/1 or DAS/2 data sources. For DAS-clients an XML interface is available that allows to obtain the listing programmatically.
For more info on this please see the documentation.
