The Data Access Portal provides RESTful web services APIs for programmatic use of the DAP, as well as an OAI-PMH provider for harvesting metadata.

There are three main groups of web service endpoints that can be used:

CSIRO staff only:

  • GET
  • POST
Use this to programmatically create DAP collections.

Comparison of Versions

For searching and accessing DAP collections, the options are to use /ws/v1 ( or /ws/v2 (

Although /ws/v2 is still in development, it retains all the features of /ws/v1 and adds a number of new features.  Generally speaking /ws/v2 is a better option, although it is possible you will need to re-factor any code that uses it after a new DAP release.
