Extension talk:Semantic Internal Objects

Internal objects and redirects
If you have an article with internal object definitions and a redirect onto that article, then internal objects are created for both the article and the redirect. Hence querying the internal object will then produce hits for the article and for the redirect. (Makes for magic doubling of project manpower. :-) ) --F.trott 14:34, 7 September 2009 (UTC)

Link to pagename in query results
I use #ask with mainlabel=- to query internal objects and suppress the meaningless main column. The column with the name of the semantic relation contains page names (in my case with a namespace prefix), but without links to the pages. Can this be activated somehow? --AndreasMangold 16:51, 9 January 2010 (UTC)


 * My guess is that the property that points to those page names is of type "String", instead of "Page"; and thus that the property's type just needs to be changed - is that right? Yaron Koren 18:39, 10 January 2010 (UTC)


 * Yes, it is right. Thank you very much for answering my question and for helping me to solve this problem. --AndreasMangold 19:33, 10 January 2010 (UTC)

Need to resave for internal objects to appear
I'm having a problem where a query for the internal objects of a certain property doesn't show objects that have been created after the query or that have been modified. I have to manually resave the page where I am using #ask for the new internal objects or modifications to appear. Any help or insight would be appreciated. Thanks. --128.54.162.143 00:21, 11 January 2010 (UTC)


 * This is probably just an issue of MediaWiki caching. If you "refresh" the page (i.e., by hitting the "refresh" tab that goes to "action=purge"), you should be able to refresh the query results, without needing to resave anything. Yaron Koren 01:03, 11 January 2010 (UTC)

Ah, you're right. Hitting the refresh tab did make the results appear. If I did not use the refresh tab, would the results eventually show up? --128.54.162.143 04:24, 11 January 2010 (UTC)


 * Yeah - usually within a day or so. Yaron Koren 04:46, 11 January 2010 (UTC)


 * Ah I see. Well thank you very much for your help. --128.54.162.143 05:27, 11 January 2010 (UTC)

Support for text data type?
Properties with data type "text" seem not to work with Semantic Internal Objects (and SMW 1.4.3). The problem disappeared after having changed the data type to "string". Will the "text" data type be supported in the future or are there any mistakes I could have made? --Thai 13:37, 9 February 2010 (UTC)


 * Ooh, I never thought to test that one... that's a pretty big deal. I just fixed it now, in a new version, 0.3 (which also has a fix for working with SMW 1.5). Thanks for the bug report. Yaron Koren 17:53, 10 February 2010 (UTC)


 * Wow, that was fast. Great work, thanks! --Thai 20:56, 10 February 2010 (UTC)

data type for property
I query internal object. The value for a property of internal property shows as a red link. It seems that the data type is assumed to be page. How can I set the data type to String?


 * You should define a page for that property, at "Property:page-name", adding "Has type::String"; just as with SMW. Yaron Koren 14:15, 16 February 2010 (UTC)
 * thanks. After I define Property page, it works.

Incorrect link to pagename in query results
I'm having a problem where the link to pagenames in query results is always Object. My test is as follows:

Create a test page with the following wiki text. This page contains the parser function '#set_internal'

Create another page with the following query.

which yields the following

My wiki is using
 * Mediawiki version 1.15.1
 * Semantic Mediawiki 1.5g-SVN (which I believe is the same as 1.4.3.1)
 * Semantic Internal Objects 0.3

Any help would be greatly appreciated.


 * This was fixed after an email discussion; the problem was solved by upgrading from PHP 5.1.6 to 5.2.10, as strange as that sounds. Yaron Koren 16:05, 17 February 2010 (UTC)
