Oblog or not (Prolog Logtalk)

Sometime ago I added some bits to en.wikipedia.org on Logtalk (since updated by the author of Logtalk himself.)  In the Prolog wikipedia article, I now see mention of Oblog. Or not.

Every link on the web that I can see says the same thing of Margaret McDougall, Oblog, object-oriented Prolog and EdCAAD.

Now I believe that EdCAAD is ESALA.

And Oblog?  A wiki obus and not an opus?
