Re: [Rdfapi-php-interest] FILTER implemented?

[<tob...@we...>]

Hi.
Yes FILTER queries are supported but we have still some problems with 
complex filters and filters that contain type casts. You should have no 
problems with "FILTER  (?date >= 12345 && ?date <= 54321)" .

Regards
Tobias

[Rdfapi-php-interest] FILTER implemented?

[GSO <gs...@ya...>]

A quick question if I may, are FILTER queries currently supported?  An example:

PREFIX ll: <http://www.gsowww.uklinux.net/librarylinks/vocabulary#>
SELECT *
WHERE { ?url ll:title ?title .
	?url ll:abstract ?abstract .
	?url ll:date ?date .  FILTER  (?date >= 12345 && ?date <= 54321) .
	?url ll:publisher ?publisher }
ORDER BY DESC(?date)

Re: [Rdfapi-php-interest] Bug report

[<jsp...@gm...>]

I have noticed this error message some days ago as well.

The problem is almost in the end of scripts edit.php and query.php

You need to add a space between opening tag <?php and character '}'.
It seems. PHP 5.2 went more strict to code formatting :-)

Select "View Source" from the menu.

You could do that, but then it wouldn't be an RDF file any more, and  
therefore most RDF tools would not recognize it.

(As a better solution, you could use an XML processing instruction to  
associate a CSS or XSLT stylesheet with the RDF document, see [1].)

RDF files are not meant to be displayed to a human. It doesn't really  
matter if it's parsed as XML, or if the raw XML is displayed, Non- 
geeks will not be able to understand either of those. Look at how  
links to RSS and Atom feeds are usually handled, they are hidden away  
behind [RSS] buttons or <link> elements in the HTML head, human  
readers will usually not see it, and RSS clients know where to look  
for it. I think the same approach should be used for RDF.

Yours,
Richard

[Rdfapi-php-interest] view RDF file in Firefox

[AJ C. <ca...@gm...>]

When firefox opens a rdf file generated by rdfapi, it automatically parses
it as xml file. The result is unreadable. So, I want Firefox to open rdf
file as is, showing content within xml structure. Any suggestion how to do
that?  Maybe something can be added to the  top of rdf file, which will
prevent it from parsing by xml parser.  Or configure firefox not to parse
rdf file. But I can't find a way to add rdf file type to firefox download
manager.

[Rdfapi-php-interest] Bug report

RDF DB Utils, when clicking on Edit or Query, results in the following error:

(humble apologies for not having glanced at the code myself).

Re: [Rdfapi-php-interest] SPARQL query error

Bug fixed, there should be a ':' in the PREFIX declaration. i.e,
'PREFIX ll: <...>'.

This colon is omitted in the RAP SPARQL documentation, threw me out a bit.

Re: [Rdfapi-php-interest] Are the URLs case-sensitive?

[<jsp...@gm...>]

Hello,

thanks for answer. You actually expected it but I wanted to be sure.
So the result is that the best practise is to avoid any name colisions
and I did so.

Best regards.

In RDF, URIrefs are case-sensitive.

> noncase- sesitive way?

In general, RAP handles URIrefs case-sensitive. But PHP ignores case =20
in some places, such as function names and class names. For example, =20
RDF::TYPE() is the same as rdf::type(). There's nothing we can do =20
about this, it's the PHP language.

[Chris B. <bi...@ze...>]

Hi Christian,

it great that you want to work on RAP, do bug fixes and extend RAP's
functionality. Especially work on the SPARQL engine is highly welcome, for
instance a better SPARQL to SQL rewriting algorithm would be really cool. Do
you work together with Sören's other student who is doing the D2RQ
implementation in PHP?
Do you also work on OntoWiki? I saw Sören's presentation about OntoWiki at
ISWC and it really seams to be a very nice tool.

I'm not to sure about porting RAP to PEAR. RAP consists of quite a number of
interlinked classes and the last time it was tried to fit RAP into the PEAR
naming schema  we were not too happy with the
results(http://pear.php.net/package/RDF). So if you want to contribute to
the core classes of RAP, I think working on improved exeption handling and
porting the core classes to PHP5 (for instance using the PHP standard
iterators instead of our propietary iterators) would be much more usefull
than just to rename the classes as it was done for the PEAR RAP version in
2004. Tobias already started into this direction and I'm sure, he will be
happy to send you his code.

Please send the patches that you already have to Tobias and he will put them
into the CVS. Later, you will of course also get CVS access.

The unit tests are at
http://rdfapi-php.cvs.sourceforge.net/rdfapi-php/rdfapi-php/test/unit/

Cheers

Hello all,


I am a student of information technologies in Leipzig, Germany and I am
doing my master/German Diplom under supervision of Sören Auer (creator
of Powl). My task is to port Powl to use SPARQL, and to fix/enhance
RAP's SPARQL engine to be more efficient and support the QL standard better.

Now I do already have some patches lying on my harddisk that fix some of
the simple bugs in the bug tracker, and half of a bigger one that wraps
RAP into a PEAR-compatible package that can be installed and used more
easily than today. Question is if the devs here do want this, or if I'm
wasting my time.

Advantages of the PEAR approach are:
- Consistent class namings that don't clash with other packages. For
this, I prefixed the classes with RAP_ and modified them according to
the directory structure (e.g. RAP_Model_DbModel since it's in
RAP/Model/DbModel.php)
- Classes include the files they need directly, without those strange
"proxy" files you are currently using (such as Model/DBase.php) that
only include two files.
- One of the bigger advatages: including files is a breeze, since PEAR
has its own include path in most PHP installations - no need to define a
RDFAPI_INCLUDE_DIR, just do a "require_once RAP/Model/DbModel.php" and
you're done.
- Very easily installable: "pear install RAP-0.9.6.tgz" and it's done.
That way, other packages can /depend/ on RAP, so that it gets installed
automatically if they install some PEAR-compatible-packaged application.


I will spend the next 3/4 year working on Powl and RAP. May I get CVS
access (username is cw...@us...) some time in the
future? Whom shall I sent my patches?


Another question: test/Readme.txt states that there are Unit tests for
the API on the homepage. Unfortunately, I did not find them there or in
CVS. Could somebody point me to the right place please?

[Rdfapi-php-interest] Are the URLs case-sensitive?

[<jsp...@gm...>]

Hello folks!

While working on an ontology and later implementing it as a RAP
vocabulary class, one question came on my mind?

Are URLs case-sensitive or not?

And my further question is if RAP handles URIref in a case- or
noncase- sesitive way?

It is very importnant if you have properties' and classes' names equal ;-)

Thanks for your answer

[Tom H. <tom...@gm...>]

Hi Christian,

That sounds like great news that you'll have time to work on RAP. I
can't speak on behalf of the developers at all, but as an enthusiastic
user of RAP (in implementing projects such revyu.com) I love the idea
of even more development time being available to work on the library.

In particular the work on the SPARQL engine sounds great. I'll keep an
ear open for how it's going, and good luck :D

Tom.

[Rdfapi-php-interest] may have solved part of the "missing class" problem

[atat <ast...@ya...>]

As it turned out several of the .php files from the SPARQL client are incom=
patible with PHP 5.1.4. The start with "<?" instead of "<?php" so I fixed t=
hat and now the code runs fine...But when I tried to run =0A=0A=09SPARQLEng=
ine::writeQueryResultAsHtmlTable($result);=0Ainstead of looping, I get this=
=0A=0AFatal error: Class 'SPARQLEngine' not found=0A=0AAnother compatibilit=

[Rdfapi-php-interest] Help2

[Danilo S. B. <ds...@ho...>]

My problem is with ResModel. I wrote MemModel in the last email.

Thanks. I was reading :

"Creating a Resource does not make the Resource visible to the model; 
Resources are only "in" Models if Statements about them are added to the 
Model"
What for ResModel exist , if we can´t use it to store in a bank without 
statements ?

Thanks

[Danilo S. B. <ds...@ho...>]

I don´t get store MemModel in my DB

No error messages are show. I don´t know what to do even more.

Someone could send a complete example of creating a MEMMODELl (without 
files) and storing in a data base ?. By statemant i get.
It´s kind urgent.  Thank you very much !

Re: [Rdfapi-php-interest] [rdfapi-php - Help] RAP and Dbmodel

RAP has a dataset API which you can use to combine several documents into a 
RDF dataset.
See 
http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi/tutorial/usingNamedGraphs.htm 
for details.

Cheers

Re: [Rdfapi-php-interest] Double rdf:type gives bug in RAP netapi?

[Hans T. <han...@qu...>]

Richard,

If I am well informed multiple typing, i.e. multiple inheritance, is normal
practice in RDF/RDFS/OWL.

Would using rdf:about the 2nd to nth time inside a triple store help to
solve this problem?

Regards,
Hans

You are right Benjamin, and I was wrong. The spec says that the rdf:ID must
indeed be unique. Apologies for spreading misinformation ...

(The full rule is: The same combination of rdf:ID and xml:base must never
occur twice in a document, taking into account that xml:base is inherited to
XML child elements.)

So it's indeed a RAP bug.

Richard
