Hi Richard, Thanks for the feedback. The character encoding in the document headers a= re fine. After the query, the characters are escaped like this "\u00D0" (= correct Unicode values but escaped instead of the actual characters).

That's OK, but the original version should work now as well:
$this->ontModel =3D $this->dbModel->getOntModel(RDFS_VOCABULARY);
> =09

OntResource("http://www.w3.org/1999/02/22-rdf-syntax-=20

Here's the problem. You're not supposed to create OntResources =20
directly. Use the $ontModel->createXXX() methods instead.
$test =3D $this->ontModel->createOntProperty("http://www.w3.org/=20
1999/02/22-rdf-syntax-ns#type");
> $sup =3D $test->listRDFTypes();
Then you can do:
foreach($sup as $type) {
echo $type->getURI();
}
Output for me is: http://www.w3.org/1999/02/22-rdf-syntax-ns#Property.
Sorry again.

Hi Richard,
I tried the getOntModelForBaseModel method with a fresh CVS. But I still=20
have an error... here is my code for tests :
<?php
define("RDFAPI_INCLUDE_DIR", "/var/www/wikisem/rdfapi-php/api/");
include(RDFAPI_INCLUDE_DIR . "RdfAPI.php");
include("/var/www/wiki-s/config.inc.php");
$wiki =3D new Wiki($config);
Class Wiki
{
function Wiki($config)
{
$store =3D ModelFactory::getDbStore(
$config['db_engine'],
$config['db_server'],
$config['db_database'],
$config['db_user'],
$config['db_password']);
$this->dbModel =3D $store->getModel('http://rn7.net/2006/02/07');
$this->dbModel->writeAsHtmlTable(); // To verify if the model is=20
correctly loaded
$this->ontModel =3D=20
ModelFactory::getOntModelForBaseModel($this->dbModel, RDFS_VOCABULARY);
=09
$test =3D new=20
OntResource("http://www.w3.org/1999/02/22-rdf-syntax-ns#type");
$sup =3D $test->listRDFTypes();
}
=09
}
?>
The model is correctly loaded from the base and a HTML table of 329=20
lines is correctly displayed. There are plenty of rdf:type in the model=20
; so listRDFTypes should give an answer... Instead I get a :
Fatal error: Call to a member function on a non-object in=20
/var/www/wikisem/rdfapi-cvs/rdfapi-php/api/ontModel/OntResource.php on=20
line 402
Is my syntax for creating the OntModem correct ?

That's an interesting scenario. Would it work if you replaced the whole model on the server with the changed version from the Mozilla client?

But, as always, getting anything beyond US-=20 ASCII to work can be a serious pain. It's all a question of getting the character encoding right. By =20 default, RAP assumes all data to be UTF-8 encoded. If your data is =20 not UTF-8 encoded, then you either have to convert it to UTF-8 =20 (recommended) or set DEFAULT_ENCODING in constants.php to the =20 encoding of your data (For the cyrillic alphabet, try "iso-8859-5" or =20= "windows-1251"). Make sure that all your XML files start with an xml declaration (e.g. =20= "<?xml version=3D"1.0" encoding=3D"UTF-8"?>", or whatever encoding = you're =20 using instead of UTF-8). RAP-generated XML files will have this =20 automatically. If you output HTML, make sure it has this inside the <title> element: <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3DUTF-8"> (or whatever encoding you're using instead of UTF-8). I'm not sure if =20= all RAP-generated HTML has this. RAP can't convert between different encodings, and can't combine RDF =20 input from different encodings. That's why I always recommend doing =20 everything in UTF-8. Most other encodings lack some characters that =20 some people will need. If this doesn't help, could you please provide a more complete =20 example of what you're doing and where it doesn't work.

I'd probably suggest adding a configuration constant to allow the switch? My requirements are a bit more involved than just serialization since I want Mozilla to pass back to the server information about changes made to the datasource locally. I therefore need to make sure that Mozilla is given enough information that it can pass back to the server and allow me to identify and modify my DBmodel statements as necessary. I'll certainly pass back to the community what I come up with as a solution. since RAP seems like the ideal backend to a server based Mozilla datasource. Geraint |

Hi, Does RAP support non-ASCII characters in XML literals and if so, how? For= example, to query and output the following information: <dc:description rdf:parseType=3D"Literal"><span lang=3D"bg">=D0=91=D1=8A=D0= =BB=D0=B3=D0=B0=D1=80=D1=81=D0=BA=D0=B8</span> (Bulgarian)</dc:descriptio= n> Note: I've tried setting the "UNIC_RDF" constant to FALSE (in api/constan= ts.php) but that did not help. This is what is returned: <span lang=3D\\"bg\\">\u00D0\u0091\u00D1\u008A\u00D0\u00BB\u00D0\u00B3\u0= 0D0\u00B0\u00D1\u0080\u00D1\u0081\u00D0\u00BA\u00D0\u00B8</span> (Bulgari= an) Thanks, Shadi |

Hi all,
There are two new methods in ModelFactory:
getOntModelForBaseModel($baseModel, $vocabulary)
getResModelForBaseModel($baseModel)
They create ResModels and OntModels from an already existing model.
The first one was necessary to make Model::getOntModel work. For
consistency, I also added the second one.
There are a bunch of new unit tests for this in /test/unit/Model/
Model_tests.php and /test/unit/Model/ModelFactory_tests.php.
Best,
Richard

Charles, a fix is in CVS now. (Tobias gave me CVS commit access, =20

Sorry, you're right ... I assumed that it was just the simple =20
spelling error in the method, but the problem is somewhat more =20
complicated. There's some code missing from the method. I'm working =20

I meant just put the (fixed) two lines of getOntModel into your own =20
code, but as we know now, that doesn't work.
Here's another thing you can try: Create the OntModel with =20
ModelFactory::getOntModel(DBMODEL, RDFS_VOCABULARY) instead of =20
$dbModel->getOntModel(RDFS_VOCABULARY). You'll have to find out how =20
to initialise the database connection in constants.php though.

Ok. I made the fix :

I am building a mozilla datasource but am having some difficulties with RDF containers. As far as I can tell Mozilla cannot handle Seq or Bag entries of type RDF:_/n/ , expecting an RDF:li in both cases. RAP serializes these nodes as RDF:_/n/ in all cases (as far as I can tell). Am I missing something or is there a way to tell RAP to serialize these nodes as RDF:li (tracking the order with another attribute possibly?) or does someone have experience in getting gecko/mozilla to recognise RDF:_/n/ nodes within containers? thanks Geraint |

in the function isSeq() the constant RDF_SQE is used instead of RDF_SEQ. |

Hi Charles,
This seems to be caused by a bug in RAP. Here's a snippet from model/=20
Model.php:
function & getOntModel($vocabulary) {
require_once( RDFAPI_INCLUDE_DIR . PACKAGE_ONTMODEL);
return new OntModel(& $this, $vocab);
}
The problem is $vocabulary/$vocab, the fix should be obvious.
You could fix it in your own copy of RAP, or set up the OntModel =20
directly, without using getOntModel.

Hi,
I'm not very familiar with OOP and I wonder how to use OntModel methods=20
on a DbModel. I write here an example in order to precise my context.
<?php
define("RDFAPI_INCLUDE_DIR", "/var/www/wikisem/rdfapi-php/api/");
include(RDFAPI_INCLUDE_DIR . "RdfAPI.php");
include("/var/www/wikisem/config.inc.php"); // Define $config array
$wiki =3D new Wiki($config);
Class Wiki
{
function Wiki($config)
{
$store =3D ModelFactory::getDbStore(
$config['db_engine'],
$config['db_server'],
$config['db_database'],
$config['db_user'],
$config['db_password']);
$this->dbModel =3D $store->getModel('http://ex.net/2006/02/07');
$this->ontModel =3D $this->dbModel->getOntModel(RDFS_VOCABULARY);
$test =3D new=20
OntResource("http://www.w3.org/1999/02/22-rdf-syntax-ns#type");
$sup =3D $test->listRDFTypes();
}
=09
}
?>
produce a "Fatal error: Call to a member function on a non-object in=20
/var/www/wikisem/rdfapi-php093/api/ontModel/OntResource.php on line 402"
To test this example, RDF and RDFS have been loaded in the dbmodel=20
"http://ex.net/2006/02/07".
Thanks in advance,

I have answered part of my question. I switched to PHP4 and mysql (instead of mysqli) and the close statements are not necessay. This appears therefore to be a problem with adodb for msqli since the docs for adodb claims that "close" statements are managed for you. The close statements to no harm and allow PHP5.1.2 to work so it may be worth adding them to the dbmodel api code. Geraint |

I am new to RAP (I'm looking at it to develop a Firefox/RDF based
application and am looking for a good way to keep my server datasources
in sync)- it looks neat so far :-) but I've come across a couple of
problems.
1. Running through the Test:Manipulate DbModel I figured out that I had
to call getNewModel if the model didn't exist. A note to this effect or
adding ti to the source code would be handy.
2. I encountered adodb errors in 2 places where the mysql commands were
out of sync (I'm using MySQL 4.1.14 and PHP 5.1.2). I upgraded the
adodb drivers to the latest versions but that was no help. To fix the
problem I had to modify two functions in DbStore and DbModel by adding a
$res->close() statement.
My modified code is :
function modelExists($modelURI) {
$res =& $this->dbConn->execute("SELECT COUNT(*) FROM models
WHERE modelURI = '" .$modelURI ."'");
if (!$res)
echo $this->dbConn->errorMsg();
else {
$res->close();
if (!$res->fields[0])
return FALSE;
return TRUE;
}
}
function contains(&$statement) {
$sql = 'SELECT modelID FROM statements
WHERE modelID = ' .$this->modelID;
$sql .= $this->_createDynSqlPart_SPO($statement->subj,
$statement->pred, $statement->obj);
$res =& $this->dbConn->getOne($sql);
if (!$res)
return FALSE;
$res->close();
return TRUE;
}
I don't have any other Databases to test this on. Is this a specific
bug to the mysqli driver?

Hi,
The N3 parser has a bug that causes broken triples in cases like this:
<foo>
:bar "bar";
:baz "baz";
.
The last statement (<foo> :baz "baz") is terminated by a semicolon
*and* a dot. This is legal in N3, and in fact quite common because
that way you can't mix up the end-of-line punctuation.
RAP's parser doesn't recognize this, sees a third triple with a null
predicate and object, and generates two notices.
Here's a test case for /test/unit/Syntax/n3Parser_test.php that
catches the bug:
function testLoneSemicolon() {
$n3 = '<a> <b> <c> ; .';
$parser = &new N3Parser();
$model = &$parser->parse2model($n3, false);
$this->assertEqual(1, $model->size());
$this->assertNoErrors();
}
Here's the fix for /api/syntax/N3Parser.php . I've added two lines to
the getPovs method, it's the comment line and the one after.
function getPovs($list) {
$povs = array();
while (in_array(';', $list)) {
$r=$this->posns($list,';');
$pos=array_slice($r,0,2);
$r = $this->getSpan($list, $pos[0], $pos[1]);
$pov=$r[0];
$list=$r[1];
// skip lone semicolons, e.g. "<a> <b> <c> ; ."
if (count($pov) == 1) continue;
$povs[]=array_slice($pov,1);
}
Best,
Richard

Hi, I am not sure how exactly the OntModel works but be aware! FOAF and relationship module are not ontologies but "plain" RDF Schemas.

Hi, I used RAP to write a FOAF parser [1], in which I use MemModel to read my RDF files. I recently thaught about FOAF extensions, as the Relationship vocabulary [2], which defines some subproperties of foaf:knows. At the moment, with my MemModel, I use findFirstMatchingStatement($subject, FOAF::KNOWS, $null) to get all foaf:knows classes related to my subject. But, I assume, it won't work if the RDF files that use rel:worksWith instead of foaf:knows. Is that the role of OntModel to make this kind of queries work ? If so, should I have to write somewhere (in vocabulary folder) the Relationship model and its mapping with FOAF ? Thanx for any advice on this point.
