For what it's worth Dia format is already used in other contexts (I
believe phpMyAdmin has it as an export format)
Similarly I'm not a lawyer but as long as your not using any Dia code I
don't see the XML format itself being a problem, after all XML is an
open system and you are simply parsing it to extract it's data so as
long as you have the appropriate rights for the content of said file
and an appropriately licenses XML parser you should be fine
Slightly concerned about "greatly inspired by it", be careful that
doesn't become "minor copy-paste" or method renaming as that's clearly
an issue
As ever for actual legal advice find somebody qualified in your
jurisdiction to give such advice
tl;dr: Just using the format should be fine but it would be good to
include an acknowledgement of/link to Dia
