Summary: TDML Runner - type-sensitive comparison
Key: DAFFODIL-2026
URL: https://issues.apache.org/jira/browse/DAFFODIL-2026
Project: Daffodil
Issue Type: Improvement
Components: TDML Runner
Affects Versions: 2.2.0
Reporter: Michael Beckerle
Fix For: 2.3.0
TDML runner needs to be able to implement type-specific comparisons when
comparing actual and expected infosets.
This is because there are representations of types like dates and times that
are equivalent.
E.g.,
<date1>2010-12-30Z</date1>
and
<date1>2010-12-30+00:00</date1>
These are entirely equivalent.
We need to perform type-specific comparison here.
This needs to occur based on the DFDL schema's type information.
DFDL implementations aren't going to provide uniform (or even any) projection
of type information into the infoset when represented in XML. So we can't
depend on say, xsi:type information (DAFFODIL-182) functionality to tell us to
compare as dates.
This means the XML comparison logic must be an XML-schema-aware walk of the
data.
