Assistance Requested: Yellow "No results" Bar

From semantic-mediawiki.org

Thanks for the quick reply! I've seen that mentioned elsewhere and for the life of me cannot find how to explicitly define data types. I've spent a few days googling for it and came up dry. I'll look into the sandbox, but if you would please elaborate a little and show me what I'm missing in my subobject defintions, I would greatly appreciate it.

I added the link to the help page on setting datatypes to properties to the datatype page for better results. Thanks for noting that it was obviously not the easiest page to find.
