1. 21/1/03J.E Campagne Towards an OpRelease 2.0 OpData (v1): need OpAlgo,… Memory Resident Data Model classes Hits,Digits,TrackElements,TrackKinematics + Repository of that classes (TDataStore) OpRData (v1) : need ROOT only ROOT Persistent version Data Model classes OpIO (v1): need OpAlgo, ROOT,… Generic DataLoader/DataSaver +Specific Storage Manager (HBookToRoot*) Aida Ntuple ROOT Tree with Folders ** *: need ROOT > 3.03/09 **: fully supported by R.Brun 1 2,3 4 5 Common to all applications

2. 21/1/03J.E Campagne Other packages status u OpRec v2 –Algorithm chain: DataLoader, Pattern, Tracking, DataSaver –Pattern v4: already presented in previous meeting (cf. A.Cazes + J.E note) –Tracking v2 (new version) »has been updated according to OpAlgo framework »flexible to use different tracking (next: Spectro tracking) –Kalman v1r1: no change –A demo.C of output ROOT Tree debug application is available u OpUtils v1 –Some constants used in OpRec have been transfered (not fully satisfactory) u OpMath v1 (new package) –Defined a bridge for matrix/vector with CLHEP library u OpAlgo v3r4 –Already presented u For the Simulation/Generation cf. L. Chaussard’s talk.
