Talk Namespace with semantic links

From semantic-mediawiki.org

Well, if you look long enough for a meaningful reason you will find one. Reality has it that everything seems possible, so I will remove this sentence.

About your issue. I just tested on my test wiki by adding

$smwgNamespacesWithSemanticLinks[NS_TALK] = true;

after the enableSemantics call and indeed properties may now be set and they also pop up in my query results. Also the help message at the top tells me that I may now add annotations to the talk pages in main talk. There must be something else in the water at your end since I cannot confirm your findings.

It eventually turned out our admin had moved the wiki directory to a new location while leaving the old copy in place. Thus I was editing a localsettings.php to no effect... Sorry for the false alarm, and thank you for the (as always) kind and patient response.
