Responses

In pydap 2.2+ the server responses are also pluggable. Out–of–the–box pydap comes with the typical DAP responses — DAS, DDS, etc. —, but new ones can be easily added.

A useful response you'll probably want to install on you server is the HTML response. This response creates a simple HTML form for each dataset that allows the user to select and download data in ASCII format using only a browser. This is always a good alternative if there's no DAP client available.

The list of responses include:

• HTML response: for downloading data in ASCII format using a HTML form.
• JSON response: JSON is a lightweight data–interchange format that is easily consumed by Javascript; a JSON response if specially useful for AJAX interfaces that access DAP servers.
• WMS response: this response makes pydap work as a Web Map Service server, allowing WMS clients to visualize data stored in the server. The response also includes a KML file to automatically import and visualize the data inside Google Earth.
