Serendipity● In 2011 I bought a horse & a car● I needed to park near my house on the weekend without a permit● My house is near 3 zones with different tariffs and hours and I DID NOT KNOW IT !!!● I over paid for months but worked it out just before the hackathon● The data that I had already thought about was presented in front of me
Why us?● Almost nobody in the parking business parks..● Locals mostly work out a way to get a parmit● That leaves the tourists who dont visit the same place often enough by car to notice
THEY THEY KNOW DONT KNOW stuff you know butYOUKNOW nice.. they dont know but do you know that they dont know ??
● Open Data is not necessarily useful data – Manage expectations – Pursue a tipping point Developers Data Open Data
● About the data – Make sure it is complete useable – Write background information – Actively ask the community for feedback – Be prepared to improve the data – Provide a contact person – Real time is best, otherwise update regularly
● Use the language of the developer – Provide some specifc challenges – If possible use english as well as dutch – Provide json – Provide rest – GEO : google maps not KML – Understand who you are dealing with
● Especially consider the indie developer – Make sure a creative mind can understand the data – Provide calculations and business rules – Provide a way to contact you – Dont force the developer to create a server infrastructure
