Hi,

We are still unable to get history upon importing a data source. This has worked in the past on MySQL, but not successfully on Virtuoso.

We have a cloned version of ASKW (non-edited) running on our machines. We have commented out line 532 of ModelController; tried setting the variable to "true". In all the debugging, it appears that the variable
is set to "true", but we still don't see any history.

Here are some details from debugging:

ModelController.php commented line#532

$versioning = $this->_erfurt->getVersioning();

$oldValue = $versioning->isVersioningEnabled(); //$versioning-

enableVersioning(false);

            $this->_handleImport($post, true);

When I debug this functionality I found :

Call Stack:

1. ModelController->createAction
2. ModelController->_handleImport
3. $this->_erfurt->getStore()->getNewModel
   a. $this->_backendAdapter->createModel
   b. $this->getModel
4. $this->_erfurt->getStore()->importRdf
   a. $this->_backendAdapter->importRdf
   i. $importSql = $this->_getImportSql;
   ii. $this->_execSql('CALL
   DB.DBA.RDF_LOAD_RDFXML(XML_URI_GET_AND_CACHE('http://localhost/
   Ontologies/classtest.owl'), 'http://localhost/OntoWiki/classtest/',
   'http://localhost/OntoWiki/classtest/')');
   b. $this->_backendAdapter->init()

We had originally reported this on the google group, but thought I would report it here.

We need to have this functionality work for our release next week. Ideas on what can be done?

thanks in advance!
Lisa

To get around the URL limit in #34 I removed the faun and go configurations and saved. After saving, and getting the "config sucessfully changed" message, faun and go are there again with all their subproperties.

OntoWiki git from 2012-02-18.

Hi All,

Adding a new namespace to the list of namespaces and a corresponding prefix doesn't work properly.

Only when new files are added in OntoWiki, a correct prefix is visible for those new files. For old files the old prefix (like ns0) is still visible. Even when you clear the Erfurt Cache.

hi @cannelony - when I add an instance, the service does not preselect the type of the new resource.
ideally

• the type is preselected and the user should not need to edit / modify that
• the widget of the type is hidden

Hi All,

I tried to modify the getAvailableModels() method in the ModelList extension. (in Erfurt/Store/Adapter/Virtuoso.php)

I changed the SQL query to a SPARQL query. But it doesn't work.

my code:
public function getAvailableModels()
{
if (null === $this->_graphs) {
$this->_graphs = array();
$rid = $this->_execSparql('SELECT DISTINCT ?resourceUri FROM http://mde.wolterskluwer.de/wkdDocument/wkd.nt WHERE{ ?resourceUri rdf:type http://mde.wolterskluwer.de/wkdDocument }');
if ($rid) {
$graphs = $this->_odbcResultToArray($rid);
$this->_graphs = array();
foreach ($graphs as $graph) {
$this->_graphs[$graph] = array('modelIri' => $graph);
}
}
}

At the moment my program crashes when I run this. But when I comment the line '$this->_graphs[$graph] = array('modelIri' => $graph);' the program doesn't crash anymore.

(When i do the SPARQL query in Virtuoso i get back:

resourceUri
http://schema.wolterskluwer.de/resource/abn.rdf

So my SPARQL query is correct.)

<relative_path> should work with leading "./".

Currently <relative_path> has to be MPATH=extensions/<extension_name> but MPATH=./extensions/<extension_name> creates a wring symlink.

http://ontowiki.net links to google code only, not to github. Github should be the central place, only the wiki on GH linking to selected docs on google code that have not yet been transferred.

The LinkedDataServer extension doesn't work.
You can try it with
wget -q -O - --header="Accept: application/rdf+xml" http://people.comiles.eu/natanael

you are right, it currently only works in combination with the site plugin ...

If I run "make cs-check-intensive" I get an overview of the files with the amount of Errors and Warnings and a second overview which violations are how often. (similar to cs-check but with warnings)

How can I see in which lines I commit the violations? Is there an option similar to "make cs-check-full" also for "intensive"?

currently one can select a property and add a new row to the table
but you can not deselect it

The documentation is at tooooo many places:

• ontowiki.net has http://ontowiki.net/Projects/OntoWiki/FirstSteps - which is linked nowhere else than on ontowiki.net
• many documentation pages are on http://code.google.com/p/ontowiki/w/list
• a bit of documentation is on https://github.com/AKSW/OntoWiki/wiki
• some documentation, not mentioned anywhere on any of the three previous documentation places, is readme.md in the sources.

I know that putting everything at one place takes much time, but at least give an overview with links to the docs at a central place.

When using big files as model,

• An sql error is returned when going to the history. : Expression recursion is too deep () in query:

Solved by changing:
model = '' . $graphUri . '' AND ( resource = '' . implode ('' OR resource = '' ,$resources) .
INTO
model = '' . $graphUri . '' AND ( resource IN ('' . implode ('' , '' ,$resources) . '' ))

• An SPARQL error is returned when you want to see all instances.

Solved by changing the list of sameTerm in the sparql query to a construction like this one:

SELECT DISTINCT ?resourceUri ?__TYPE WHERE{?resourceUri http://www.w3.org/1999/02/22-rdf-syntax-ns#type ?__TYPE. FILTER(?resourceUri IN(http://resource.wolterskluwer.de/legislation/bd_kwg , http://vocabulary.wolterskluwer.de/stw/Befreiung , http://vocabulary.wolterskluwer.de/stw/Verbriefungen))}

(This also leads to an performance gain if you remove OPTIONAL in the query also.)

Registering a new user from an openid ("cweiske.de") worked fine. Logging in with OpenID "cweiske.de' did not work, though. Logging in with "http://cweiske.de/" as OpenID works.

This is because the URL does not get expanded automatically to "http://cweiske.de/" as it did in the registration.

The protocol should be added automatically, and the trailing slash after the hostname, too - when it's missing.

Hi,

i just tested the cs stuff, and i really like it!

I had already installed the CodeSniffer pear library, and cs-install says it fails, because of that, but actually succeeds. maybe you ignore that error there. (should also occur when cs-uninstalling and then cs-install again - because the uninstall doesnt uninstalls the pear stuff)

and if i add a var_dump or print_r (and also exit and echo), i would like cs to complain about that. is there a simple way to disable cs for one(current) commit? for example: i fix all cs errors that i can, but some remain (for example a print_r to the log).

@seebi also suggested that you could make something that prevents us from commiting to the master branch.

what do you think?

regards,
Jonas

its enough to have a working version in semantic-extensions

@haschek tested IE7 and IE8. the linkeddataserver has problems with the mimetype requests IE7+8 sends (this is known also for lod2.eu)

Here is the german issue description: "Desweiteren funzt die Content Negotiation nicht wirklich, entweder schickt der IE keinen korrekten accept header zwecks accept type, es gibt einen Bug beim auswerten, oder die Content Negotiation ist zu hart eingestellt, was die relativen Werte angeht. Also ein Aufruf von aksw.org/Resource führt im IE irgendwie immer zu aksw.org/Resource.ttl - das Problem existiert sicher auch auf anderen Seiten, die mit der OW site extension betrieben werden."

hi jonas, can you check and fix the functionality of the defaultmodel extension please? It seems to be broken ...

The "suggested properties" window shows:

In use elsewhere (3)
address Address Opening Hours

I cannot distinguish between address and Address, and Ontowiki does not give any indication what each property exactly is.

I'd like to see the properties URL when hovering the property. This can be achieved with a title attribute.

I'm trying to use OntoWiki as address book with the vCard schema[1]. In this schema, addresses are not string properties on the vcard/person but properties of child nodes that are linked with the http://www.w3.org/2006/vcard/ns#adr property.

Adding such an address child node in ontowiki is not easy, because when clicking "add property" you may choose the address type, but have to provide an URI. I'd rather have that URI autogenerated by selecting the type of the child node.

Short: When adding a property, I'd like to be able to specify the type of the resource instead of its URI. The URI should be autogenerated then depending on the type.

hi :) I know that when one clicks an instance it gets redirected to the viewController (with no Action parameter). I also know that when one updates its instance through RDFAuthor the updateURI to which data gets sent is redirected to updateController. Only trouble is I can't seem to find it anywhere. So far I found the 'view' part of MVC for the view in properties.phtml .

Where are controllers located?

Thanks for any help.

Again and again I get a
Fatal error: Allowed memory size of XXXXXXXXX bytes exhausted (tried to allocate XX bytes)
after a while clicking around. I think we have some kind of (memory) leak in the session. After destroying the session everything works again.
Maybe somebody wants to track the memory usage with a profiler.

hi, I am trying to use data from dbpedia with instances that I have in database. For the sake of simplicity let say I have a list of buildings (the instances). Each of these buildings has many properties one of which is the country where it is built. I tried adding property "http://dbpedia.org/ontology/country" and for value a resource "http://dbpedia.org/page/France" but for some reason when I click on (+)(expand) it says "No predicates found". The desired effect would be to show the data like on the page "http://dbpedia.org/page/France".
I did not make any changes to the configuration of datagathering extension since I wasn't able to find any manual on how to do it.

Would you be so helpfull and help me configure the extension. Your help would be greatly appreciated.

as discussed ...

Hi,
I'm having an issue with imports.

That is:

Ontology A defines two classes

Ontology B defines instances of those classes
Ontology B owl:imports Ontology A.

Ontology C owl:imports Ontology B.
nothing newly defined (yet)

When I load A, then B and click on B, I do see the instances defined in B.
However, when I then load C, I see nothing.

I would expect, when I load C, to see the classes from A and the instances defined in B.

I tried again with C owl:imports B and C owl:imports A, but had the same problem.

I need to integrate multiple data sources from different ontologies.

Any ideas what could be causing this issue?

Here is the source.
From Ontology A (schema) (as resource):
http://localhost/OntoWiki/schema a owl:Ontology .

From Ontology B (externalsource1) (as resource):
http://localhost/OntoWiki/externalsource1 a owl:Ontology ;
owl:imports http://localhost/OntoWiki/schema .

From Ontology C (reg-instance) (as resource):
http://localhost/OntoWiki/reg-instance a owl:Ontology ;
owl:imports http://localhost/OntoWiki/externalsource1, http://localhost/OntoWiki/schema .

I have made sure that the appropriate prefixes were defined in the "configure KB".

Kind Regards,
Lisa

When trying to configure the navigation extension with http://example.org/exconf/conf/?name=navigation (e.g. to show the counts and hide empty classes), I get the following error on a stock apache2 instance from Ubuntu:

The requested URL's length exceeds the capacity limit for this server.

The URL is over 8kib, which is quite long.

Please use POST instead of GET.

Hello guys,

I've got only two questions :-)

I want to send SPARQL-request to OntoWiki and then I want to recieve the result in the Typo3-Semantic-extension.

1. Is there a SPARQL-interface so Semantic can fetch the data?
2. Have you got a technical documentation or something?

Jens from FH Hannover

Hi,
We were using the ordering module to add ORDERY BY ascending clauses to our queries and received this error:

Erfurt_Sparql_ParserException: missing ")" in ORDER BY clause.
C:\wamp\www\AKSW\OntoWiki\libraries\Erfurt\Erfurt\Sparql\Parser.php@1338

We were trying to debug by looking at the Erfurt_Sparql_Query2 object to see how the ORDER BY clause is constructed in the array.

We ran across the "add" function, but couldn't find it elsewhere in the code. There are other "add*" functions, but not "add" on its own that we found.

Any ideas on how to debug this? We really need ordering :)

thanks,
lisa

ab -n 100 -c 10 OWURI

develop vs. semantic-extension cached vs. semantic extension uncached (cache dir deleted)

von Konrad abicht: grad aufgeploppt: Wenn du hier http://lod2.eu/Project/Silk.html unten auf
"page source" klickst, kommt ein OW error ...

after clicking a property in the "show property" module, different errors occur:

• types and attribute values are not shown
• different errors are shown

e.g. Warning: mysqli_stmt::close() [mysqli-stmt.close]: Couldn't fetch mysqli_stmt in /home/seebi/var/www/ow/aksw.org/libraries/Zend/Db/Statement/Mysqli.php on line 105

since @cannelony wants to enhance the table view with edit widgets, it would be great to have a working "show properties" feature ...

The code sniffer handles the second variable in a list as public.

In the following example both variables are private, but the code sniffers recognizes $_onMap as private, but $_inCluster as public.

 private $_onMap, $_inCluster;

I get following sniffer error:

| ERROR | Public member variable "_inCluster" must not contain a leading
|       | underscore

hi canellony,

if I try to add a property to an empty resource (no statements exists), I do not get back an UI.

1. turn on the location bar (resource -> toggle location bar)
2. type a new URI in and return
3. click on Add Property

I get following sniff error

239 | ERROR | Expected 1 space after comma in function call; 2 found
| | (Generic.Functions.FunctionCallArgumentSpacing.TooMuchSpaceAfterComma)
241 | ERROR | Expected 1 space after comma in function call; 3 found
| | (Generic.Functions.FunctionCallArgumentSpacing.TooMuchSpaceAfterComma)
242 | ERROR | Expected 1 space after comma in function call; 2 found
| | (Generic.Functions.FunctionCallArgumentSpacing.TooMuchSpaceAfterComma)

for following code

$bnd['top'] = new Erfurt_Sparql_Query2_Smaller('?lat',  $bnd['top']);
$bnd['rgt'] = new Erfurt_Sparql_Query2_Smaller('?long', $bnd['rgt']);
$bnd['btm'] = new Erfurt_Sparql_Query2_Larger('?lat',   $bnd['btm']);
$bnd['lft'] = new Erfurt_Sparql_Query2_Larger('?long',  $bnd['lft']);
$dttyps[]   = new Erfurt_Sparql_Query2_ConditionalAndExpression($bnd);

We only want a check that at least one space exists but argument alignment should be possible

the last update was 2011-03-17

probably it needs to be adjusted to github...

hi jonas,

I just reviewed a view new n3 files.
can you fix the following easy issues which would help me in my review work:

• the private namespace without a prefix (:) should end with an slash
• add a statement owconfig:privateNamespace <.the namespace.>
• change :caching -> owconfig:caching
• change :priority -> owconfig:prority
• use 4 spaces indention instead of 2
• add an empty line after the prefix declarations
• add a "<> foaf:primaryTopic :xxx ." statement
• generate a statement for each context: owconfig:context <..> (subject the extension not the module)
• remove rdfs:comment "fixme"; lines
• add URIs as <..> instead of "..." (use regexp from Util class)

can you generate than all doap.n3 files new please?

On a fresh debian installation with the virtuoso-opensource package installed, the DSN is VOS instead of the vos505 that config.ini-dist contains. This makes setup unnecessarily complicated.

• package git extensions
• ...

we have problems with includes, lisa as well as hgg told us different installations with that issue:

http://zak.ontowiki.de/zak/kontakt/ --> http://zak.ontowiki.de/zak/modell/
this does work

http://zak.ontowiki.de/zak/traeger/ --> http://zak.ontowiki.de/zak/kontakt/
(this does not work)

with the actual development branch checkout it is impossible to configure KBs. No data is being stored while using the save button.

When registering a new user on application/register, a form validation error (e.g. password too short) leaves you with an empty form. All data have to be input again.

Hi all,

When you are in the instances view of a model and you go to the history of this model.
Then returning back to the instances view will reset the limit.

Problem is solved by removing the line :

$query->setLimit(0);

in ListAction().

this are the open issues from the old issues-thread:

• wikipage for sniff explanation
• CS integration for Vim
• install CS on all submodules/extensions

In the instance model, we are unable to see classes which do not have instances defined.

see this thread: http://groups.google.com/group/ontowiki-user/browse_thread/thread/cb2777f2fb333e0b#
