[developers] QUERY REGARDING GERMAN GRAMMAR'S MRS GENERATION

[Michael Wayne Goodman]

Hi Naman,

Apologies for the late reply.

The properties whose names begin with hyphens (e.g. --PSV) are problematic
in DMRS XML, because it results in the following structure:

    <sortinfo --psv="non-apsv" [...] />

XML attribute names may not begin with hyphens (
https://www.w3.org/TR/xml/#NT-NameStartChar), so the XML parser throws an
error. PyDelphin is not currently doing anything to remedy this situation,
but I'm not sure what is the appropriate change to make. Perhaps PyDelphin
should just throw a more descriptive error message rather than attempt to
modify the attribute name or (currently) do nothing. I can recommend a few
remedies for you:

 1. Rename properties such as "--PSV" to "__PSV" (or something) before
MRS->DMRS conversion, and then rename it back on DMRS->MRS conversion.

 2. Use the DMRS-JSON format instead of DMRX (since JSON is not affected by
this issue).

 3. Remove the --PSV property (and similar) entirely, if they are not
valuable for your work.

Does this help?

I have compiled the german grammar .
But in the ACE generated MRS of any german sentence there seems to be an
additional '--' preffixed to few attributes as PSV, ZU which is leading to
an error generation on attempt to generate DMRS for the same.

Also, On removing this '--' the DMRS is generated absolutely fine.
Please suggest me a remedy for this issue.It would be highly appreciated.
