all XML & RDF validations (e.g. rapper).<br>
<br></div><div>When I do my tests, it seems that in case the error occurs t=
he submitted RDF is not saved, and hence the RDF in CKAN is that one of the=
CKAN RDF generation process. Is that true? In that case the level of the m=

ke the above error message a proper validation result. <br></div><div>=C2=
=A0=C2=A0=C2=A0 Note this solves also the problem of the meaningless error =
message. There is no reference at all in the message to know about which ca=
ll/object it is. So the problem is unresolvable with this message. And putt=
ing CKAN in debug mode logging for that is not very sensible.<br>
</div><div>2) ensure that the handling of RDF (in rdfxml-format) inside the=

<div>Hello David,<br>
<br>
we don't do any postprocessing for the data we send.<br>
<br>
It's pure rdf content as read from the file. So, we depend on CKA=
N
how it will digest it.<br>
If we need to do some postprocessing, can you give clarification
on the matter ?<br>
<br>
Also, does that have to do with the problem we faced with unicode
exceptions from CKAN as well ?<br>
<br>
Kind regards<br>

<div>There appears to be a lot of malformed rdf documents in the

<div>After some investigation this seems to due to the data send
