100-continue / 400 RDF parser reported errors

I'm curious what to make of this:

*   Trying 123.456.7.8...

* connected

400 RDF parser reported errors

This is a 4store SPARQL server v1.1.5

The command being used to send the data is:

curl --header 'Content-type: text/xml' --url 'http://foo.bar.baz:1234/data/http://foo.bar.baz/foobar' --verbose --upload-file 'foo.rdf'

foo.rdf has been validated with the W3C RDF validator.

Hi,

Can you try with "application/rdf+xml" as content type ?

If still does not work try to parse the file with rapper:

rapper -i rdfxml foo.rdf

rapper is a raptor utility and 4store uses raptor internally. If
rapper parses the file 4store should parse it as well.

Thanks, Manuel. Changing the content type (duh--I might have remembered that, but it's been ages since I wanted to load the rdf/xml and not turtle) allows the upload, but doesn't fix the second problem I'm having: I get this result if I use a regex FILTER on a query:

<!-- warning: invalid UTF-8 string -->

I uploaded the rdf/xml (I normally just upload the turtle) because I had massaged it with rapper; here's the output:

rapper: Parsing URI file:[blah].rdf with parser rdfxml

rapper: Serializing with serializer ntriples

rapper: Parsing returned 1415 triples

This file is valid according to the W3C validator. I infer from what I've read elsewhere on this board that the error I'm getting might be related to UTF-8 issues, but I can't understand why in this case. However, if I do remove the regex from the query, I get results back. I'm frankly puzzled.

I think I have seen this problem before. Have you build 4store and
dependencies yourself ? If so I believe you need to build PCRE
enabling unicode properties.

./configure --enable-unicode-properties.

No: I used the 4store-1.1.5 disk image for Snow Leopard. But the tip below is useful in case I ever build from source. (Haven't done so yet, though.) Btw, I didn't  have this problem before using 1.0.3 on Leopard. The same data worked fine there. (I noticed the problem after I upgraded OS and 4Store version.)

I tested with this option in the version 1.1.5 :
configure: WARNING: unrecognized options: --enable-unicode-properties

It's an option on the pcre library, not 4store itsself.

The version shipped with the DMG must be incorrectly configured too.

I'll try and build a new one tomorrow.

Hi there

I get the same UTF error by using FILTER with regex. Could someone upload a new DMG image for Mac?

Thank you very much!

cheers

An update on this.

I've been trying since I sent this mail, but keep running into road blocks! I had to update Fink (among other things), and that's been taking ages.

Hello all :)

I like 4store and I would like to use it on a mac book pro and on a mac pro with Mavericks.

I downloaded and installed the offered mac version of 4store (v 1.1.5).

However I noted that FILTER Regex expressions are not running on a 4store running on a mac osx 10.9.

The error is related to some UTF-8 support which should be missing in my (default) case :<!-- warning: invalid UTF-8 string -->

I am not interested (in this first phase) in building from the source code and if I could avoid it I'd be glad.

****What steps should I do in order to get also the FILTER Regex on 4store running?****

Thank you so much for any hint on this. 

Kind regards

[swh]

Have you checked that your input data is legal UTF-8?

I'm not 100% sure where that error originates from, but it sounds like you have UTF-8 enabled, but the UTF-8 parser didn't like it.

Try cutting down to a trivial amount of data, and see if you can narrow down what string is causing the error, or try running your input data through iconv.
