4. Overall vision Provide tools for accelerator operation
Using Service Oriented Architecture
Provides decoupling and ability to update while in production
The service and the protocol is the main contract where compatibility is kept (not the database, api, etc…)
Using web technologies for the server
Very solid support from industry
Work with firewalls
Use-case driven
Start from a need not from technology
Focused on deliverables products
Something you can download and install

5. Looking for people That work well with others
Share the architecture vision
Task focused
Deliverable oriented
With a need to solve
Various level of expertise are welcome
Could use this as a learning experience

6. Infrastructure Continuous build/test infrastructure
Each subproject is on both sourceforge and java.net
Sourforge: website, wiki, mercurial repository
Java.net: JIRA bug tracking
We (should) have a once a month meeting
Round the table, what I have released past month, what I’ll be working next month
Inpromptu meetings with Google hangout

7. Server technologies More requirements on how services are done
It’s the important part
Multiple people need to be able to support it
Should be homogeneous
All installable in a cluster with similar configuration
Standardize on Java EE
Using Glassfish (standard implementation)
Still haven’t standardized on internals
JDBC vs JPA or JAX-RS or …

8. Client technologies Whatever you want! Php/Ruby/… for web ui
Python for scripts or uis with pyQt
Java for CSS, Swing uis, applets, Android
Objective C for Apple
As long the end product is buildable from command line, packaged, deployable and functional

9. Laundry list Move build/test infrastructure out of BNL
In the cloud!
Factor out common parts
Server authorization scheme
Client side configuration management
Client side connection management
Single sign on
Authenticate once for all applications
Integrate with Linux and/or Windows logon
Forward credentials for web ui

10. Laundry list Support different databases
Move database layer to JPA
Provide different scripts
Setup test infrastructure
Support different application servers (jboss, websphere, …)

11. Wish list Equipment status and schedule management
Something along the lines of ISA 95 part 2
Lock Out Tag Out service
Manages requests for locking devices during maintenance
Other services
Do you have another service that fits the architecture and spirit? Let us know!
