8. Worldwide Protein Data Bank Common D&A Project January 2010 Update Sequence Editor Tool Development Lessons Learned  Iterative development and active Annotator involvement is essential – and takes time.  Addressing integration issues with existing systems in terms of modularity, process ordering and data availability poses significant challenges.  Agile process of development and planning supports adaptation to evolving requirements.  We will need to further consider the most efficient level of granularity for the deployment of new functionality in existing systems in future planning.

9. Worldwide Protein Data Bank Common D&A Project January 2010 Update Design Convergence Accomplishments Master Format, API, WFM, WFE, UI Distributed development on a complex project is challenging Tag team development of WFE and API’s  Straw men articulation – flush out WFE/API requirements for representative Use Cases  WFE pseudo code developed against straw men.  API integration layer will be developed against this pseudo code.  WFE will then be implemented against the API

10. Worldwide Protein Data Bank Common D&A Project January 2010 Update Accomplishments: WF infrastructure - Integration of Sequence Processing  Tracking and Status DB developed and installed at RCSB and PDBe for development purposes.  Work Flow Manager (WFM) –Prototype user testing on-going –Requirements refined and prototype updated –Infrastructure complete – to be deployed for testing this week  Work Flow Manager User Interface (WFM UI) –User prototype created, input received and prototype enhanced –Initial Level 1 annotator interface signed off by annotators –Level 2/3/4 interfaces prototyped and under review –Level 3 /4 under further development

11. Worldwide Protein Data Bank Common D&A Project January 2010 Update PDBe resource  Workflow XML –Luana/Tom : 1 day total to complete annotator requirements  WFE component supporting Sequence Processing : –Tom, 1-2 days per week ongoing, estimating 5-6 days (3 actual weeks) to complete after all api’s are in place  WFM –Luana : currently full time – work is being prioritised to define the subset of requirements to be delivered in March.  Web resources : interfaces and WFM –External services –technology requirements have been defined. Timeline tbd. Critical Path.  Other resources –Wim : python expertise –Swanand : python expertise (after 13 th Feb) – fall-back

12. Worldwide Protein Data Bank Common D&A Project January 2010 Update RCSB Resources  Web Tools - –Currently supporting development and alpha-testing sites –Will add production site for Feb deployment  Database Support – –MySQL database server for status and tracking database  Application Support –Project SVN code repository –JIRA issue tracking system –Project documentation and information site (Drupal) –Automated build system for API and application tools  People – –Vladimir – API and build system (Python/C++) –Li – DB system and status and tracking API (Python/SQL) –Rahip – Sequence Editor Tool (Javascript/CSS) –Zukang/Raul/John – DP applications (C++/Python)

13. Worldwide Protein Data Bank Common D&A Project January 2010 Update Updated Timeline Summary Sequence Processing 1.

19. Worldwide Protein Data Bank Common D&A Project January 2010 Update Deliverable update: WFM Design Functional Architectural design  Will present progress and tracking information  Will start/stop and restart the workflow engine in executing data processing tasks  Will work in a fully distributed web-based mode  Will provide a launch point for tasks requiring interactive or graphical interactions. Two modes defined – Immediate mode – all processing occurs in a single session (simple case). Deferred mode – requests for input are registered with the workflow manager for later processing by annotator
