Prosciutto Palermo Valley Mobile Sessions - English

  1. 1. The Prosciutto Project an open source mobile application engine
  2. 2. Which problems do we have today? <ul><li>Device fragmentation </li></ul><ul><ul><li>Hardware (screen, memory, input) </li></ul></ul><ul><ul><li>Software (APIs, implementation differences) </li></ul></ul><ul><ul><li>Device configuration (preferences) </li></ul></ul><ul><ul><li>Network configuration(carriers) </li></ul></ul><ul><li>More than 20 different vendors </li></ul><ul><li>More than 5000 different models </li></ul><ul><li>More than 11.000 firmware versions *Source: WURFL (Wireless Universal Resource File, April 22nd 2009) </li></ul>
  3. 3. <ul><li>Write once, run everywhere? </li></ul><ul><li>No: Write once, debug everywhere! </li></ul><ul><li>Redistribution. The costs of “planting” an application are re paid with each new release (communication, marketing campaign, distribution). </li></ul><ul><li>Testing and Porting costs </li></ul>Which problems do we have today?
  4. 4. Motivations and vision <ul><li>The spirit: </li></ul><ul><ul><li>Configurable enough to build any application </li></ul></ul><ul><ul><li>Separate the business logic from the actual java code </li></ul></ul><ul><ul><li>Model the logic outside the engine </li></ul></ul><ul><ul><li>Implement in an easy configuration </li></ul></ul><ul><ul><li>Have analysts/modelers build the application, without specific skills </li></ul></ul><ul><li>Bring technology to the people in every sense (the engine should run on cheap handsets, aggregate value added services, allow an unskilled - in the programming sense - designer build something out of nothing) </li></ul>
  5. 5. Motivations and vision <ul><li>Separate the business logic from the java code </li></ul>
  6. 6. Motivations and vision <ul><li>Separate the business logic from the java code </li></ul>
  7. 7. What is Prosciutto? <ul><li>The Prosciutto Project is an engine implemented on Java ME. </li></ul><ul><li>You could think of it as a RAD framework, or a distributable engine that aims to scale the problem of device fragmentation. </li></ul><ul><li>It is based on a basic and intuitive markup language in order to define UI objects and their behavior. </li></ul><ul><li>Prosciutto applications run on the Prosciutto engine. </li></ul><ul><li>Any application which aims to let the user navigate data (online u offline) and represent those on screen can be built in Prosciutto. </li></ul>
  8. 8. Why an engine? <ul><li>… and not a WAP application? </li></ul><ul><ul><li>Access to various API and new functionalities </li></ul></ul><ul><ul><li>Security </li></ul></ul><ul><ul><li>Freedom </li></ul></ul>
  9. 9. Why an engine? <ul><li>… and not a vertical application ? </li></ul><ul><li>Fast development and prototyping vs. Efficiency in the solving of a vertical problem </li></ul><ul><li>False dicotomy </li></ul><ul><ul><li>Prosciutto solves those problems that are common to everyone </li></ul></ul><ul><ul><li>Vertical applications provide a concrete solution to a specific and well-defined problem </li></ul></ul><ul><ul><li>Prosciutto provides a ground on which the application building is an activity that allows the designer to think freely without caring about the underlying platform </li></ul></ul><ul><ul><li>It allows for focusing on the vertical problem (application) in an efficient and quick way </li></ul></ul>
  10. 10. Why Java? <ul><li>More than 90% of the actual handsets do incorporate some version of a JVM. </li></ul><ul><li>There are more Java developers than in any other mobile platform </li></ul><ul><ul><li>Symbian </li></ul></ul><ul><ul><li>iPhone </li></ul></ul><ul><ul><li>.NET CF (Windows Mobile) </li></ul></ul><ul><li>(that’s why Google created its own Java language as the base development platform for Android) </li></ul>
  11. 11. Why open source? <ul><li>Spread the idea of sharing </li></ul><ul><li>The problems attacked by Prosciutto are everybody’s pain: </li></ul><ul><ul><ul><li>Device fragmentation </li></ul></ul></ul><ul><ul><ul><li>Limited resources </li></ul></ul></ul><ul><ul><ul><li>Code hacks to support specifics of the different models and vendors </li></ul></ul></ul><ul><li>Therefore, the solutions to those problems should not be one company’s assets, but rather belong to the whole community. </li></ul><ul><li>If we all engage in tackling those problems that we all have , the faster we can focus our efforts in adding value </li></ul><ul><li>Value added is essentially the differntiator </li></ul><ul><li>V.A. can only come from vertical applications, and not from solving the common problems again and again (DRY concept) </li></ul>
  12. 12. What does it solve? <ul><li>Device fragmentation? Yes! </li></ul><ul><li>Write once, run everywhere? Yes! </li></ul><ul><li>Redistribution. Yes! Costs of “planting” an application are paid only once. </li></ul><ul><li>Minimize testing and porting costs. </li></ul><ul><li>Therefore, a lower development cost and a better time-to-market </li></ul>
  13. 13. Markup <ul><li>Prosciutto is based on a simple idea: the layout and appearance as well as app behavior should be defined in a unique XML model. </li></ul><ul><li>HelloWorld: </li></ul>
  14. 14. Example: Hello World
  15. 15. Example: Login
  16. 16. Tested handsets
