The quick answer is: no, because the p99 DB is not public.
I asked previously about obtaining information from the p99 DB for the wiki but it wasn't going to happen.
I would say the wiki is 90% of the way there on items and spells. Other areas such as quests are not as complete.
It's unlikely the wiki will ever be as database oriented as an allakhazam clone. For instance, the list of mobs in each zone is done by hand (for now). However, there is always the potential to make it more like a database. I discussed a start
in this post.
It will also never be exactly right/complete, because the DB is not public. But I think that it can be actually more useful, that way, than a complete DB browser which really doesn't let you focus on the most interesting parts.
