Summary: Ability to compute CRC, checksums, parity fields. - related to layering? Key: DAFFODIL-2221 URL: https://issues.apache.org/jira/browse/DAFFODIL-2221 Project: Daffodil Issue Type: New Feature Components: DFDL Language, Front End Affects Versions: 2.4.0 Reporter: Mike Beckerle Fix For: 3.0.0 A DFDL language extension has been requested allowing data to be validated, and unparsed that contains fields computed based on representation of other elements/groups. E.g., checksums, or CRC codes, or parity elements. Seems closely related to the layering features added to Daffodil as an experimental DFDL extension feature, and proposed for inclusion in DFDL v2.0 version of the standard. But it's not exactly the same, as there needs to be a way to refer to the layer, and obtain a value from the layer when parsing and when unparsing. -- This message was sent by Atlassian Jira (v8.3.4#803005)
