---------------------------------------
Summary: AIS format example - a layer should also compute checksum
field
Key: DAFFODIL-2563
URL: https://issues.apache.org/jira/browse/DAFFODIL-2563
Project: Daffodil
Issue Type: Improvement
Components: Back End
Affects Versions: 3.1.0
Reporter: Mike Beckerle
Daffodil has a layer transform for AIS format's payload armoring.
The tests of this use a complete AIS record with a final checksum field.
However, this checksum is not recalculated.
We should enhance this schema with a checksum calculation using the new
features implemented for DAFFODIL-2221.
This layer, and the AIS encoding layer should become pluggable (per
DAFFODIL-1927), and be implemented as part of an AIS DFDL schema project (on
github) which includes the test/example schema for a complete AIS message, as
well as the Scala code for the 2 layers needed. One for the payload armoring,
another one for the checksum.
