Freebase should now have a complete copy of all National Register of Historic Places entries which are of International, National, or State significance. The Local significance listings still used the old strategy of only reconciling existing topics.
Below is a summary of the before and after counts. We picked up 4,535 entries which had either been added to Wikipedia, added to the Register, or both. On top of that we created another 20,553 entries, bringing the grand total to over 35,000 listings.
|Starting Count||Existing Topics Reconciled||New Topics Created||Ending Count|
Each topic contains a fair amount of information, so the entire load amount to about 750,000 "facts" (or "triples" in RDF-speak), bring the total number of facts that I've written to Freebase to over 1.1M. Unfortunately, their "tallybot" which does the nightly updating of totals has been broken for a while, so I'm only getting credited with a paltry 300K.
The one remaining loose end is to try and do a better job of reconciling the architects/builders and what the Park Service calls "significant people" associated with the listing. This will require human vetting of a queue of tasks, so it'll require some additional infrastructure to be put in place before I can set people loose on working on it.
