Creating a property on a private wikibase instance #419

jjkoehorst · 2019-07-04T06:19:04Z

I am trying to create properties using the Java API:

public static void main(String[] args) throws Exception {

        BasicApiConnection connection = new BasicApiConnection(siteIri);

        connection.login(USERNAME, PASSWORD);

        if (!connection.isLoggedIn()) {
            throw new Exception("Login failed");
        }

        WikibaseDataEditor wbde = new WikibaseDataEditor(connection, siteIri);

        wbde.setEditAsBot(true);


        PropertyDocumentBuilder propertyDocumentBuilder = PropertyDocumentBuilder.forPropertyIdAndDatatype(PropertyIdValue.NULL, DatatypeIdValue.DT_PROPERTY);
        propertyDocumentBuilder.withLabel("Label text " + uuid, "en");
        propertyDocumentBuilder.withDescription("Description " + uuid , "en");
        propertyDocumentBuilder.withAlias("My alias " + uuid, "en");

        PropertyDocument propertyDocument = propertyDocumentBuilder.build();


        wbde.createPropertyDocument(propertyDocument, "bot summary " + uuid);
    }

It does create the property but I end up with a NullPointer which is not really clear in itself to me:

when disabling the UUID and run the program twice I get the following message:

I assume this is the case due to an already existing property with the exact same label and description? However I am not certain since the message is not really clear in itself...

The text was updated successfully, but these errors were encountered:

Tpt · 2019-07-04T19:30:55Z

Hi! Thank you for the bug report. I'm not sure of what is happening exactly for your first problem (@wetneb do you have an idea?). About the second error, indeed, Wikibase enforces that the (label, description) couples are unique.

wetneb · 2019-07-06T08:57:34Z

For the first bug it looks like the datatype of the property as returned by Wikibase is not understood. It would be worth adding some proper error handling there to understand which datatype value caused this, and fix it accordingly. We might also want to update the list of supported datatypes to include the recently added ones.

Hi, I am newcomer to wikidata, configured the api successfully in eclipse, run all examples from tutorial, but I have not been able to connect to our private wiki, and obtained the same results I just obtained with wikidata.org and test.wikidata.org.

I tried the published code, and obtained the following result:

log4j:WARN No appenders could be found for logger (org.wikidata.wdtk.wikibaseapi.ApiConnection).
log4j:WARN Please initialize the log4j system properly.

when ussing the examplerhelper function provided with the api, I obtained the following result:

any recommendation to solve the issue?, what is the best way to get access to a given wikidata page?

wetneb · 2019-08-23T12:11:54Z

Instead of using https://wikidata.pst.ag/wiki/Main_Page as the URL of your Wikibase instance, you should use the MediaWiki API endpoint, which should be https://wikidata.pst.ag/w/api.php.

luisenriqueramos1977 · 2019-08-23T12:44:00Z

Dear wetneb,

thanks for the recommendation, I could get the connection, and write the property values, however after ending the task, it generates another error, and I wonder what could be the reason?

The last instruction executed was:

    wbde.createPropertyDocument(propertyDocument, "Luis Test bot summary ");

and I think the problem is there.

I has same problem. After debug by program, the class PropertyDocument of Wikidata-Toolkit:0.10.0 require datatype parameter, but my wikibase:REL1_31 not return datatype field when create new property.

Luis

this exception because you have same property on wikibase already.
