Advanced Mashups with EMML/Mashup Studio

Presto Wires allows both business users and developers to create mashups in a simple, graphical way. The features and scope for Wires mashups, however, is only part of the full capabilities and flexibility possible with mashups.

Developers who need more robust mashup capabilities can create mashups using the Enterprise Mashup Markup Language (EMML). This XML vocabulary is a very simple, but very powerful way to quickly build mashups from Presto services or any service accessible by URL.

How to get started? Try the Creating a Simple Mashup with EMML and Mashup Studio and Creating a Mashup in EMML to Combine Reviews and Ratings tutorials to get your feet wet.

Developers use the Presto Mashup Studio for Eclipse to write mashups in EMML in the Mashup Perspective. Mashup Studio also provides robust, familiar debugging features, in the Debugging Perspective for Mashups.

Mashup Studio organizes mashups in projects. See Creating a Mashup Project for the basic steps and other common project-level tasks, such as defining servers.

See Creating a Mashup Script for the steps involved in writing mashups with EMML. This sections also covers all of EMML’s syntax. Mashup Studio includes several levels of assistance to help with syntax both for EMML and for XPath. See Expressions and Editing Assistance for more information. See Advanced Mashup Techniques for discussions of some of the intermediate and advanced techniques you can use in mashups.

Once you have a mashup script, you can debug it (see Debugging a Mashup Script) and then publish it (see Publishing a Mashup Script) to make it an active service in Presto.
