| 9 | 5 | J. Moringen | * RSB-related Issue |
| 10 | 5 | J. Moringen | ** Blender depends on Python3.2 |
| 11 | 5 | J. Moringen | ** We will make a rsb-python for porting work |
| 12 | 5 | J. Moringen | |
| 13 | 5 | J. Moringen | * Demo in one/two week(s) |
| 14 | 6 | J. Moringen | ** RSB + Blender |
| 15 | 5 | J. Moringen | ** RSB + MORSE |

| 17 | 6 | J. Moringen | h2. RSBag (Michael, Jan) |
| 18 | 1 | J. Moringen | |
| 19 | 6 | J. Moringen | h3. Current State |
| 20 | 6 | J. Moringen | |
| 21 | 6 | J. Moringen | * C++ Implementation |
| 22 | 6 | J. Moringen | ** Can write TIDELog files |
| 23 | 6 | J. Moringen | ** Partial read support |
| 24 | 6 | J. Moringen | ** Client interface and RSB integration are not finished |
| 25 | 6 | J. Moringen | ** No commandline tools |
| 26 | 6 | J. Moringen | |
| 27 | 6 | J. Moringen | * Common Lisp |
| 28 | 6 | J. Moringen | ** Can read and write |
| 29 | 6 | J. Moringen | ** Basic RSB integration (only event payloads; no meta-data yet) |
| 30 | 6 | J. Moringen | ** Commandline tools |
| 31 | 6 | J. Moringen | *** @bag-record@: almost done |
| 32 | 6 | J. Moringen | *** @bag-play@: not done yet |
| 33 | 6 | J. Moringen | |
| 34 | 6 | J. Moringen | h3. Should the TIDELog file format include per-entry meta-data? |
| 35 | 6 | J. Moringen | |
| 36 | 6 | J. Moringen | * Problem |
| 37 | 6 | J. Moringen | ** Replaying RSB events requires more than just one timestamp and the payload to be stored: event meta-data and some transport information has to be serialized and stored as well |
| 38 | 6 | J. Moringen | * Pros |
| 39 | 6 | J. Moringen | ** Slightly reduced lock-in since only a TIDELog library and an IDL of the payload are required (vs. knowledge of the event serialization mechanism) |
| 40 | 6 | J. Moringen | ** More beautiful (in Lars' words ;) |
| 41 | 6 | J. Moringen | * Cons |
| 42 | 6 | J. Moringen | ** Where to stop? Why not an arbitrary amount of blobs for each entry |
| 43 | 6 | J. Moringen | ** Requires modification of TIDELog file format |
| 44 | 6 | J. Moringen | ** Reading data from a log requires knowledge of the payload data format anyway; having to know the structure of the entire serialized event is not that much worse |
| 45 | 6 | J. Moringen | * Decision |
| 46 | 6 | J. Moringen | ** We will store serialized events in the respective entry's blob |
| 47 | 6 | J. Moringen | ** We should still talk to Ingo about this issue |
| 48 | 6 | J. Moringen | |
| 49 | 6 | J. Moringen | h3. Initial Set of Tools and supported Use-cases |
| 50 | 6 | J. Moringen | |
| 51 | 6 | J. Moringen | * No implementation in other languages (or at least not now) |
| 52 | 6 | J. Moringen | * Supported use-cases |
| 53 | 6 | J. Moringen | ** Recording one or more scopes (with filtering) |
| 54 | 6 | J. Moringen | ** Replay of events to one or more scopes (with filtering) |
| 55 | 6 | J. Moringen | |
