IBM® Sharable Code is a platform for building, sharing, and managing Web 2.0 API mashups. The platform allows creation of a common structure (or design) for Web 2.0 mashups. Users can create mashups of heterogeneous APIs (such as RSS, Atom, and REST) by having a common representation for the different parts of the APIs and the data consumed and provided by these APIs.

The mashup's interactions with end users and the interactions among the services can be directly represented in the mashup design. Views are associated with these interactions using an HTML template language. The platform also includes Web application tools for facilitating the overall design activities of mashups as well as for sharing the resulting deployed mashups and the different parts.
