List of alternative content formats:

das-json

This format is a native JSON encoding of the DAS data model. The design principle for this format is that the properties accurately match those in the specification, rather than the XML. Thus there are no distinctions made between elements, attributes and text content. Whilst this means that implementing a reciprocal XML-JSON conversion function must be done explicitly for each DAS command, using DAS in Javascript web applications is more natural.

Currently, the das-json format is defined for the sources, features and types commands.
