Hi Robert,
dbpprop properties are a simple 1:1 mapping of Wikipedia Infobox templates
properties, with no specific mapping nor special inference (I think there
are only some checks on data types).
On the contrary, dbpedia-owl properties are extracted from mappings of
Infoboxes defined on mappings.dbpedia.org website and using the DBpedia
extraction framework.
Hope this clarifies a bit your doubts.
I'm sure the other guys will give you more insights into the mechanism :)
BR
Andrea
