Preface

This document describes how to use the OPeNDAP toolkit software to build OPeNDAP data servers, clients and client-libraries. Using the objects and functions contained in the toolkit, you can create programs which serve data over the internet as well as programs that can request data from any OPeNDAP server.

This document covers release 3.4 and later of the DODS software.


Who is this Guide for?

This guide is for people who wish to use the OPeNDAP software to write a new OPeNDAP data server, a new client, or a new client library. Typically, this will only be those people who wish to serve data in a format that is not currently supported by the DODS team, or who have an existing application that uses an idiosyncratic or unusual API for data access. Most people will be able to use one of the already written servers or client libraries. See the The OPeNDAP User Guide for a list of these.

This documentation assumes that the readers are C++ programmers, are familiar with networked applications, and the POSIX programming environment. The DODS/OPeNDAP project also provides a native Java class library (API) that parallels the C++ spftware described here.(1)

Also available are two tutorials, Writing an OPeNDAP Client and Writing an OPeNDAP Server , which descrie how to write a client or a server, respectively.

Because the type of information presented in a document like this depends to a large extent on the needs of its readers we welcome your feedback and comments. In particular, if you have any questions about individual sections, email those questions and we'll send back an answer as well as including that information in the next version of this document. Send queries to: \DODSsupport.

Organization of this Document

This Guide is divided into five chapters.

Chapter 1

provides background information on the organization of the toolkit software.

Chapter 2

describes how to use the Network I/O classes to manage virtual connections.

Chapter 3

discusses how to sub-class the toolkit \Cpp classes so that they are specialized for your specific use.

Chapter 4
Chapter 4-1
Chapter 4-2

describes in detail how to write certain sections of both the data server and the client-library for a new API.

Chapter 5
Chapter 6
Chapter 7

describes how to link user programs with the new client-library implementation of an API.

\texonly{; ( tk,classref) : contains complete descriptions of all the DODS classes.}

Note that this is "not" a reference volume. See The OPeNDAP Programmer's Guideref for a concise listing of the member functions in each of the toolkit's classes.
