RDF Validator error

2006, July 28 - 11:30 — CaptSolo

Hi,

Can anyone here help with an RDF validator problem I am encountering?

See: http://tinyurl.com/prxyo
"An attempt to load the RDF from URI
'http://sparql.captsolo.net/b2evo-0.9.2/xmlsrv/sioc.php?sioc_type=user&sioc_id=2&blog=1'
failed. (Undecodable data when reading URI at byte 0 using encoding
'UTF-8'. Please check encoding and encoding declaration of your
document.)"

Note that "<?xml" is located at byte 0 and it can't be undecodable UTF-8.

Also - not so sure now, but when I had similar errors before the same
page sometimes validates and sometimes - not. And while RDF Validator
reports problems with it, the SIOC Browser displays this page OK.

Thanks,
Uldis

I seem to remember some reports of validator bugs not long ago, not
sure of the specifics except I think whether or not visual graphs were
created depended on how much load there was on the server, not enough
memory = no graph.

Are you sure it is utf-8? wget tells me this is being served as
text/html, that might be confusing the validator.

Cheers,
Danny.

There was an e-mail reporting a similar problem in June.
Just wrote him to ask if he solved the problem.

Yes. Content-Type: application/rdf+xml; charset=utf-8

The URL contains '&' and if you will not enclose it in quotes when
passing to wget or curl then the URL will be truncated at first '&'
and the blog engine will send an error page ("text/html") saying that
a page does not exist.

P.S. Looks like RDF Validator is at fault...

Hi,

That's really strange, I wget your rdf file on my server, rename it,
and it works:

http://apassant.net/tmp/tmp.rdf
=>
http://www.w3.org/RDF/Validator/ARPServlet?URI=http%3A%2F%2Fapassant.net%2Ftmp%2Ftmp.rdf&PARSE=Parse+URI%3A+&TRIPLES_AND_GRAPH=PRINT_TRIPLES&FORMAT=PNG_EMBED

Maybe the problem comes from the validator itself ?
