Abstract:
Apache Tuscany provides a comprehensive infrastructure to simplify the task of developing and managing Service Oriented Architecture (SOA) solutions based on Service Component Architecture (SCA) standard. Tuscany Java SCA is a lightweight runtime that is designed to run standalone or provisioned to different host environments.
Task is to implement a tool which generates composite diagrams from the composite files to illustrate the SCA artifacts and their wirings. SCA artifacts are composite, component, service, reference.
This tool can serve multiple purposes:
1) Help document Tuscany's tutorials and samples
2) Be integrated with the SCA domain manager to visualize the SCA domain (contributions, composites, nodes etc)
Implementation Plan:
Composite XML should be generated using the Tuscany's in-memory representation of the composite model.
It will then give as an input for the Composite Analyzer. Composite Analyzer then analyzes the XML document
and grab the relevant DOM Elements such as Composite, Component, Service, Reference, Wire etc. and starts to
build the SVG document using SVG DOM API of Apache Batik.
After Composite Analyzer built up the SVG document it will be the output which represents the composite diagram.
DOM elements (Composite, Component, Service, Reference, Wire etc.) possibly be static classes which holds the
shape of the artifact, color, other static properties and will be given the dynamic properties (such as position, size etc.)
as input, in order to create a DOM element and it will be then handover to the Composite Analyzer.
Deliverables:
- Code of the tool which will be built.
- Tests to verify the accuracy of the diagrams generated.
- User documentation on operation of the tool and sample diagrams generated.
Time-line:
April 20 - May 10
- Read on Tuscany SCA Java, understand the design, and concentrate on project relevant parts
- Read on Scalable Vector Graphics (SVG) 1.1
- Read on Apache Batik and write examples to get familiar
- Recognize all the artifacts of SCA.
May 11 - May 24
- Finalize the process view after getting the comments from the developers’ community and from my mentor.
- Start initial implementations - building artifact structures
May 24 - July 10
- Preparing for the mid-term evaluation of the project.
July 12 - August 15
- Implement Composite Analyzer
- Improve performance by using parallel design patterns.
- Develop test cases to verify the accuracy of the generated diagrams.
August 16 - August 22
- Wrap up the work done, and polishing up the code.
- Preparing for the final evaluation.
August 26
- Final evaluation deadline.
Community Interactions:
Apache Tuscany developers’ community is the main community behind this project and I highly appreciate comments/ ideas of the expert developers of Tuscany and consider those as a great opportunity to learn and contribute more and more to the improvement of Tuscany.
Biography:
I am Nirmal Fernando, final year undergraduate at Department of Computer Science and Engineering at University of Moratuwa, Sri Lanka. I am very competent at Java programming language, OOP, XML, XSL and data structures and algorithms. I am familiar with SOA concepts and web services.
I participated in GSoC 2010 for Apache Derby (RDBMS in Java) project and successfully finished the project. This is a sample of the work (final output) which I've done for Derby last summer (http://nirmalfdo.blogspot.com/p/my-work-at-gsoc-2010.html).
You can find my profile and recommendations at LinkedIn (http://www.linkedin.com/profile/view?id=54105394&trk=tab_pro).
I am looking forward to have an exciting summer with Apache Tuscany, and I consider this is a great opportunity to me, to apply my knowledge and skills into a real world application which benefits many people around the globe.
