The Digital Discovery System (DDS) of the National Science Digital Library (NSDL) is an online library devoted to digital resources related to science, technology, engineering, and math. General, K-12, and higher education resources are available. A search API provides access to the repository. The API is a REST-RPC hybrid, returning responses in XML and JSON.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
