Evaluation specs component level

Evaluation seq. num.
Use only of sub-sequent evaluations of the same evaluation is done in another setup than a previous one.
In that case copy the Evaluation specs table and fill out a new one with a new sequence number.
For the first evaluation leave this field at "1"
Evaluator-ID email [email protected] Unique ID of the evaluator that carried out this specific evaluator.
Evaluation describtion text The overall goals is first to evaluate the stability of Taverna as the in-production workflow engine. Secondly we want to test FFprobe as characterisation, file format validation and property validation tool (in combination with schematron) for 'Large Video Files'. Thirdly we would like to test the Isilon Storage performance, when the scratch storage is moved from NAS/SAN to Isilon Storage.

ReliableAndStableAssessment Reliability - Runtime stability  (focus: Taverna workflow)
Manual assessment. The workflow is set up with a workflow monitor in which each step of the workflow is recorded. If a file does not complete the workflow, it is added to the downloadlist again and is run trhough the workflow again. It is also marked as 'failed' and can be viewed on the workflow monitor GUI, and a mail is sent to the digital content manager. If it later completes it is simply marked 'completed'. If the workflow cannot complete due to an inconsistency (e.g. wrong file format), the content provider is contacted.
true true
NumberOfFailedFilesAcceptable Reliability - Runtime stability (focus: Ffprobe component)
Manual assessment. Ffprobe returns errors on broken files. This is acceptable as these files should not continue through the workflow, but rather be re-downloaded. Ffprobe may also miss audiotracks that are not present from the beginning of the video file, but added at a later time stamp. This means that the characterisation information from Ffprobe is not complete. We however also have characterisation information from a different tool, so we consider this acceptable.
