Treffer: Implementing the Data Access Protocol in Python

This slide deck was presented as part of the OPeNDAP Developer's Workshop, Winter 2007 that was held from February 21-23, 2007 at the NCAR Foothills Laboratory in Boulder, CO. Abstract: Pydap is an implementation of the Data Access Protocol (DAP) written from scratch in the Python programming language and based on the latest DAP 2 draft specification. The module comes with a DAP client with support for authentication and caching, allowing Python programs and scripts to access any DAP-served dataset through array-like objects. It also comes with a modular DAP server that runs in a variety of environments and that can be easily extended to support different data formats and new response types. In this talk I will present a short introduction of how to install, deploy and use pydap both as a client and as a server, covering typical usage cases. I also plan to show examples of how pydap can be extended, focusing on the existing Web Map Service (WMS) and Google Earth interfaces.
