- Define proposal to Fedora community for specification of Fixity Checking Service
- Notes from 2016-12-08 Tech Meeting
- From the draft specification:
For the purposes of the following specification, a fixity result is an extract or summary of some LDPNR made according to some explicit procedure. Fixity results are taken for the purpose of comparing different fixity results for the same resource over time, to ensure a continuity of that resource's identity according to the particular procedure used. Examples might include:
- Checksums like MD5 or SHA1, often used for digital images.
- XML Signatures
- Per-segment results as used for time-based media
Fedora offers management for fixity results in two situations: firstly, as part of content transmission, to guard against faults in transmision, and secondly, by building on its versioning system to support on-demand fixity results, to guard against faults in persistence.
