1. Version 4 Charter – Discussion Bob Dalesio Greg White

2. Version 4 Base Deliverables EZPVA in C++ - provide helper classes in C++ that make use of C++ simple. (Matej) Provide the client conversion from PVAccess to PVManager (Matej) Document V3 Channel – how does a client request a variable in version 3 as a version 4 PV and multiRecord (Marty) Gather service – provide time correlated scalars into a vector that is time correlated. (Marty and Timo) Device Library – provide support for clients to request collections of PVs into a device structure. (Marty) Client requests for event filtering and data aggregation where a client can make requests on primitive PVs to be collected, queued, averaged, on specified conditions such as 10Hz or 1 Hz event. (Ralph – architect: work with Gabriele, Gabriele – can we use PVManager, Greg - use cases) Complete technical support for streaming services (All)

3. Version 4 IOC Orient development to support high performance data acquisition as required in physics and science applications Pursue this as an extension of the V3 IOC – Large buffer passing between records (Michael) – Large Buffer Driver Support (Michael/Marty) – Large buffer to PVAccess (Marty) Presentation of device data as complex data types Event Filtering -> Aggregation (averaging) -> collection (device collection)
