Having great fun #natlibscot today continuing to use http://www.digipres.org/ to choose some characterization tools to test. Focused mostly on choosing tools recommended for the ingest phase of the lifecycle. Hoping to compare these tools using some test data over the next few weeks to see which ones are easiest to use, most comprehensive and deliver results in a user friendly way. No single tool does everything apparently. Finding that balance between meeting requirements such as file format identification; metadata extraction; dependency analysis and quality assurance without slowing down the processing of large quantities of data will be an interesting challenge.
