It started in September 2011 with a Hackathon
Options!!!

What was different
● We added the“best guess” (“obvious dumbass”) logic.
● What would be the #1 FAQ?
● How much in total will it cost and what is the alternative?
● I don't want to know the details.
How did we “best”
guess
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 don't visit the same place often enough by car to notice
stuff you knowbut
they don't knowbut
do you know that they don't know ??
nice..YOU KNOW
THEY KNOW

What other stuff don't we

Parking moneyin amsterdam

to
What's the story to data
holders?
● Open Data is not necessarily useful data– Manage expectations– Pursue a tipping point
Data
Developers
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– Don't force the developer to create a server
infrastructure
