Mike Beckerle commented on DAFFODIL-1852:
-----------------------------------------
I realize I created this bug, but I have no idea what the last sentence above
"The JSON inputters/outputters would have to be adapted to JSON that does not
have the "..." around everything." means.
> Data type not available in infoset events
> -----------------------------------------
>
> Key: DAFFODIL-1852
> URL: https://issues.apache.org/jira/browse/DAFFODIL-1852
> Project: Daffodil
> Issue Type: Bug
> Components: API, Back End
> Affects Versions: 2.0.0
> Reporter: Mike Beckerle
> Priority: Major
>
> Daffodil doesn't pass the datatype for a simple value as part of the
> StartElement or StartArray events.
> This means that you can't, for example, tell whether to create the JSON
> member as a string or as a number (i.e. whether to include the "" or not).
> In XML output, this prevents putting an xsi:type="..." element on the simple
> types, which is sometimes of value.
> Daffodil ships a JSON outputter, but it just renders everything as a string,
> and the XML outputter doesn't add xsi:type attributes.
> The infoset datatype member is required part of the DFDL infoset according to
> the spec, so the lack of this information is non-conformance to the spec.
> The xsi:type attribute is planned (JIRA DFDL-182 and DFDL-1633 also) - it
> would be optional, for the XML outputters, and would either be checked or
> ignored by XML inputters.
> The JSON inputters/outputters would have to be adapted to JSON that does not
> have the "..." around everything.
