Analysis of Build Systems to Extract/Build/Generate/Ingest Fedora Digital Objects

When addressing this task, we should consult the following TDR requirements:

Collection specific requirements we should consider to some degree in DOMS B1.3, B1.4, B1.6, B2.3, C2.1, R72
File integrity checking during ingest, fail on errors: B1.6, B1.8, B2.6, R48
Proper reporting required from ingest module, ensure only complete objects are ingested and reported ok, report indicates preservation status B1.7, B1.8, B1.9, R48-49, R63
Ensure received data cannot be modified during ingest: R50
Format definitions required, note that the intended usage of the format is relevant as well, use standard format registries: B2.1, B2.2, B3.3, R48, R62, R73
Must be able to document the data we have in the repository is derived from the data we received, and how: B2.3, R51, R54-56, R59, R68
Referential integrity required between file storage and metadata (creation and validation): B4.2, B4.3, D1.5, D1.6, R64, R69
