Hi Charles, this sounds like a use case for RAP's dataset API which allows you to manipulate multiple models. See: http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi/tutorial/usingNamedGraph= s.h tm You could also use SPARQL to query across multiple Named Graphs: http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi/tutorial/usingtheSparqlE= ngi ne.htm Cheers, Chris --=20 Chris Bizer Freie Universit=E4t Berlin Phone: +49 30 838 54057 Mail: ch...@bi...

Hi, I am working on a semantic wiki (using RAP of course). For a given wiki, should I use one model or many models in a db store (one for each ontologie, for example) ? I think one model is good because it is easy to manipulate (read, write, queries, and so on). But my tool will be able to manage many wikis in a single installation (with a different knowledge base for each wiki) : in that case, many models should be better because the tool would be able to share some ontologies between different wikis (the basic ontologies like RDF, RDFS, FOAF, and so on). But is it easy to manipulate a collection of models ? What do you think about that ? What are the use cases of many models in a db store ? Does that questions make sens ? Charles Nepote. |

Hi again,
i think ModelFactory::getOntModel should be:
function & getOntModel($modelType,$vocabulary, $baseURI =3D null)
{
require_once( RDFAPI_INCLUDE_DIR . PACKAGE_ONTMODEL);
switch ($modelType)
{
case DBMODEL:
$model =3D =
ModelFactory::getDefaultDbModel($baseURI); // --> =20
instead of $model =3D ModelFactory::getDbModel($baseURI);
break;
...
otherwise $dbStore ist not an Object in ModelFactory::getDBModel

Hi, you are totally right. The function iterFind() is missing in the DbModel. I don't know why nobody had this problem before. I added the function to the DbModel and updated RAP. You can download the new version from sourceforge.

Hi all, we have released RAP - RDF API for PHP V0.93 today. The new version includes: + support for the SPARQL query language. + support for a subset of SPARQL protocol. + multiple bug fixes. RAP's new SPARQL package allows you to execute SPARQL queries against = RDF graphs and RDF datasets which may be stored in memory or in a relational database. We have also included SPARQL as additional query language into RAP's NetAPI RDF server, which allows you to query remote RDF = repositories using W3C SPARQL protocol. An introduction into the usage of RAP's SPARQL features is given in: http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi/tutorial/usingtheSparqlE= ngi ne.htm More information about RAP is found at: http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi/ Lots of thanks to=20 + Tobias Gauss for implementing SPARQL engine. + Daniel Westphal for implementing the RDF dataset API. + all users of RAP for their bug reports and bug fixes.

Hi Ghislain, yes, we are still using the old PHP4 syntax at some places in RAP as we = want most of the package to work with PHP4 as well. If you use RAP with PHP5 = you can remove all the &s.

Hi all,
While parsing an RDF file, the RdfParser die() if it cannot open the
file. (see syntax/RdfParser.php, line 2262)
So, when using RDF-API to parse a set of files, it makes my app stops
if one file cannot be found, while I'd just like it to go one step
further.
In this case, maybe it would be better to throw an exception instead
of die() ? Then, the piece of code using RD-FAPI will use a try /
catch when loading the model, so that it doesn't stop if a file is not
available.
Parser:
$input =3D @fopen($base,'r');
if(!$input) throw new Exception("RDF Parser: Could not open File:
$base. Stopped parsing.");
then, in app:
try {
$model->load($uri);
} catch (Exception e) {
echo $e;
}
BTW, there's also a strange encoding bug with PHP5. Accentuated chars
are not clearly recognized when parsing a file, even when specified
the encoding. But it works fine if I don't use str2unicode_nfc()
function anymore. I saw that in PHP5, the encoding is automatically
detected, maybe that could be a cause.
(see http://php.net/xml_parser_create_ns)
Regards,
Alex.

That's hard to say. Depends on what you're trying to achieve. RAP can do two things with OWL.

As resModel is an abstraction layer above memModel it is of course a bit slower. Daniel Westphal did some benchmarks when he implemented resModel. I = think his test showed, that resModel is only about 10% slower than memModel = (which surprised me). Daniel, so you still have the exact figures somewhere?

Hi, I'm going to implement a quite demanding application using rdfapi. I looked around and it seems the most comprehensive api in PHP. Congrat! However, I'm a lit bit concerned about the performance. For instance, the ResModel is a very convenient interface but looking at the code, I realize the overhead may be important with numerous "new" and "resNode2Node" calls. Does somebody know about rdfapi performance, especially ResModel versus MemModel ? Cheers, Ghislain. |

No, RAP's reasoning and ontology features were implemented by Daniel
Westphal as part of his diploma thesis which is finished now.
So if somebody wants to build on his work and extend RAP further towards
OWL, he is highly welcome to do so and we will incorporate the code into the
next release.

Hi,
I've been playing with RAP recently, and would like to congratulate
you on your efforts.
I've finally spent a couple of hours getting my toy code to use the
DB backend, and this seems to be working nicely so far.
One thing I did struggle with was the code to get an OntModel from
the DB. Could you tell me whether the below is appropriate:
$dbURI = "http://www.etc...";
$mysql_database = ModelFactory::getDbStore('MySQL', 'localhost',
etc...');
$memModel = $mysql_database->getModel($dbURI);
$ontModel = $memModel->getOntModel(RDFS_VOCABULARY);
This worked to a certain extent, but I was getting an error when
trying to listClasses on the ontModel:
PHP Fatal error: Call to a member function TYPE() on a non-object
in /Users/drummond/Sites/rdfapi-php/api/ontModel/OntModel.php on line
127
So I had a look and fixed the method below, which now works fine -
the getResModel() probably needs the same fix.
function & getOntModel($vocabulary)
{
require_once( RDFAPI_INCLUDE_DIR . PACKAGE_ONTMODEL);
require_once(RDFAPI_INCLUDE_DIR.'ontModel/'.$vocabulary);
$vocab = new RdfsVocabulary();
return new OntModel(& $this, $vocab);
}
Also, I keep vaguely aware of development of other APIs and
understand pOWL builds on top of RAP. Does this mean that OWL support
is likely to stay out of RAP itself?
Thanks for your time.

Hi Evan, what you are saying makes total sence. There were no clearly defined = subsets of N3 when we implemented the first version of the = parser/serializer. As there is Turtle now and the parser (hopefully) = does Turtle, we should rename it.=20 It would be great if you could make the parser pass the Turtle = conformance tests. Contributions there and also better error handling = are highly welcome.

I've been using the N3Parser for a project, and I've found it really hard to use for arbitrary input. For most syntax errors, it uses die() to exit quickly. I've replaced the calls to die() such that syntax errors cause the high-level interface to return false for incorrect syntax. The parser's parseError member is set to true, and I've added an errors member to hold errors. (Theoretically the parser could recover from some errors, so this is an array.) I also changed the unit test so it checks for a false return value rather than looking for error output. Probably the better way to handle this all is with exceptions; I think that should probably wait until PHP 5 has more penetration, though. Especially since I don't use PHP 5 yet! Patch attached. I'd be happy to revise and re-submit based on feedback. ~Evan -- Evan Prodromou <eva...@us...> |

You're right, Alex. Good catch!
Cheers,

Hi,
I think there are mistakes in some namespaces definition (file constants.ph=
p
).
define('FOAF_NS', 'http://xmlns.com/foaf/0.1/#'); define('RSS_NS', '
http://purl.org/rss/1.0/#');
should be replaced by
define('FOAF_NS', 'http://xmlns.com/foaf/0.1/'); define('RSS_NS', '
http://purl.org/rss/1.0/');
Cheers
Alex.
