AndréCheers,In case you haven't come across it before http://kulturnav.org/1f368832-7649-4386-97b6-ae40cce8752b is the entry point to the Swedish database of (primarily early) photographers curated by the Nordic Museum in Stockholm.It's not that well integrated into Wikidata yet but the plan is to fix that during early 2016. That would also allow a variety of photographs on Wikimedia Commons to be linked to these entries.André Costa | GLAM developer, Wikimedia Sverige | Andre.Costa@wikimedia.se | +46 (0)733-964574

After some cleaning, I can get the WD data formatted like my own (Name, Nationality, Dates). I can then do a simple match, where everything matches exactly. For the remainder, I then match names and dates- without Nationality, which is often very "soft" information. For those that pass a smell test (one is "English" the other is "British") I pass those along, too. For those with greater discrepancies, I look still closer. For those with still greater discrepancies, I manually, individually query my database for anyone with the same last name & same first initial to catch misspellings or different transliterations. I also occasionally put my entire database into open refine to catch instances where, for instance, a Chinese name has been given as FamilyName, GivenName in one source, and GivenName, FamilyName in another.In short, this is scrupulously- and manually- checked data. I'm not savvy enough to let an algorithm make my mistakes for me! But let me know if this seems to be more than bad luck of the draw- finding the conflicting data you found.I have also to say, I may suppress the Niepce Museum collection, as it's from a really crappy list of photographers in their collection which I found many years ago, and can no longer find. I don't want to blame them for the discrepancy, but that might be the source. I don't know.As I start to query out places of birth & death from WD in the next days, I expect to find more discrepancies. (Just today, I found dozens of folks whom ULAN gendered one way, and WD another- but were undeniably the same photographer. )Thanks,David

How are duplicates resolved, if at all? Was the Wikidata info extracted from a dump or one of the APIs?When I looked at the first person I picked at random, Pierre Berdoy (ID:269710), I see that both Wikidata and Wikipedia claim that he was born in Biarritz while the NYPL database claims he was born in Nashua, NH. So, it would appear that there are either two different people with the same name, born in different places, or the birth place is wrong.TomOn Tue, Dec 8, 2015 at 7:10 PM, David Lowe <davidlowe@nypl.org> wrote:Hello all,The Photographers' Identities Catalog (PIC) is an ongoing project of visualizing photo history through the lives of photographers and photo studios. I have information on 115,000 photographers and studios as of tonight. It is still under construction, but as I've almost completed an initial indexing of the ~12,000 photographers in WikiData, I thought I'd share it with you. We (the New York Public Library) hope to launch it officially in mid to late January. This represents about 12 years worth of my work of researching in NYPL's photography collection, censuses and business directories, and scraping or indexing trusted websites, databases, and published biographical dictionaries pertaining to photo history.Again, please bear in mind that our programmer is still hard at work (and I continue to refine and add to the data*), but we welcome your feedback, questions, critiques, etc. To see the WikiData photographers, select WikiData from the Source dropdown. Have fun!Thanks,David*Tomorrow, for instance, I'll start mining Wikidata for birth & death locations.
