The ProgrammableWeb directories are about cataloging APIs, SDKs, libraries, frameworks, Web apps and applications that consume APIs (primarily mashups and mobile apps), and pointers to sample source code found elsewhere on the Web.
The mashup directory for Web and mobile apps is a great place to curate pointers to applications that consume or depend on the other assets found in our directories (like APIs and SDKs). In a way, the mashup directory is like a showcase of apps that shows what can be done with an API. While we think it’s better if you include such a showcase with your developer portal, ProgrammableWeb’s mashup directory is also a good place to list those applications that help to demonstrate the power of your APIs and SDKs. After adding such a pointer to ProgrammableWeb’s directory, be sure to use our forms to add any related APIs, SDKs, frameworks, libraries, and pointers to sample source code (like the source code behind the app that you’re going to add to this directory) . If you have any questions about our forms, their fields, and the data model behind our directories, we recommend that you read ProgrammableWeb's New API Directory Data Model Explained.
