Re: ParseError while parsing entity in TriX

[Martynas Jusevičius]

Andy,

I've switched the output to XML version 1.1 and started getting a lot
of inexplicable and seemingly random riot warnings, such as

18:49:18 WARN  riot                 :: [line: 181, col: 15] Bad IRI:
<ply to this email directly or view it on GitHub:&#xD;
htt035f94/> Spaces are not legal in URIs/IRIs.

where line 181 simply reads:

         
<uri>https://localhost/messages/65195ff1-3549-4840-8bc2-f37a3a035f94/</uri>

Those warnings were not there using XML 1.0, which concerns me. From
the warning message it looks like the parser somehow read part of one
term on top of another.

I am honestly trying to prepare a test file right away now :) I've cut
it down to ~350 lines, but if I remove a single extra triple or even a
line of string, the warning goes away.
Can I send it off-list to you?
