What is IBM Sharable Code?

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.

How does it work?

IBM Sharable Code uses a high-level, mostly declarative, domain-specific language (DSL) to represent the entire mashup and its design. The DSL is then converted into a full Ruby on Rails (RoR) application that users can install into their own servers and further modify and improve. The platform includes three main parts:

• The core platform converts a DSL instance into a RoR application; the core is exposed as a REST service as well as command line Rake tasks.
• A builder Web application allows quick creation of the DSL instances. The builder includes various templates and wizards that make creating the DSL parts easy. The builder allow different parts of the design to be shared and reused.
• A community Web application enables easy sharing, rating, and discussion of already-deployed IBM Sharable Code mashups.
