Background
• Currently, configuration data (.db, .dbd, template and substitution files) are distributed around our network.
• IOCs can get data from different sources.
• Revision Control
• Live data in EPICS
• Various points of entry
• Keeping PV data consistent can be difficult
• Ideally, information would be stored in single central repository.
2006 EPICS Collaboration Meeting
Advantages
• Many noted in IRMIS Primer
• Data Validation
• Offer single point of entry in to system for a given task
• Others….
2006 EPICS Collaboration Meeting
Goals
Extend our IRMIS-based system Define a generic framework Solicit input to enhance portability Leverage existing progress
2006 EPICS Collaboration Meeting
Functional Requirements Methods of importing and modifying existing data (a
la IRMIS). Mechanism to make startup information available for
IOCs. Revision control and release management
procedures and interface(s). EPICS layer to adjust real-time values. Database abstraction layer All the while, ensuring settings are consistent across
facility.

Conclusion
We have a way to go in generating our requirements and starting design.
We hope to develop some relationships during this meeting.
Given the technology available, my slide presentations could be more exciting.
