This is actually a "pseudo-meetup". Ontodia is giving a talk at the SMW Conference at NYU-ITP this Friday at 9am.
If you wish to attend the talk, you'll need to register at EventBrite.
If you're only interested in the Pediacities talk, arrangements for a 1-day conference pass have been made, but for those interested in the larger topic of Collaborative Databases, Semantic Wikis and WikiData, I encourage you attend the entire conference.
Regardless, you can use the code "BIGOPENDATANYC" to get a 15% discount.
There is also a 50% academic discount. Please contact me to qualify.
