| *Scalability Challenge* \\ | _Large amounts of data (200Tbytes \+). For simple characterisation not much CPU is required but a lot of I/O is needed._ \\
Some of the files are rather large (8Gbytes) - could be a problem for some characterisation tools (not problematic for tools that only reads header information and magic bytes) \\ |

| *Other interested parties* \\ | |
| *Possible Solution approaches* | Should be simple. \\
1. Find appropriate characterisation tool that supports wav in a suitable manner \\
    * XC*L framework seems to have good wav support - evaluate and test. \\
2. Ensure this tools runs within the SCAPE platform \\ |

h1. Evaluation

| *Objectives* | This is about scaleability and functionality |
| *Success criteria* | We will have a workflow that can process WAV (and BWF) files - also larger files up to 10Gb \\ |
| *Automatic measures* | 1. Support for both WAV and BWF \\
2. Support for larger files - up to 10Gb \\
3. Process 2Tbytes of sample content in less than 24 hours \\
4. 100% of the files are identified correctly \\
5. 100% of the files gets useful and correct characterisation output \\ |
| *Manual assessment* | 1. Sample checking of the generated characterisation output \\ |
| *Actual evaluations* | links to acutual evaluations of this Issue/Scenario |
