Open Source, Open Data, Open Standards
Open standards
Standards are #BAD
Existing standards never fit your needs
They are always outdated
They are academic and over complicated
Standards - the good part
Communication
Replaceability, Substitutability
Sharing
Interoperability
Standards are evil, but we ain’t got nothing better.
Solves existing problem
Backwards compatible as much as possible
Maintained and maintainable
Certified by independent organisation
Open
Good standard
Walking on water and developing software from a specification are easy if both are frozen.

Open source loves open standards
Software is like sex, it’s better, when it’s free.
-- Linus Torvalds
Open data
What makes data “open”
No technical constraints
No legal constraints
5 star system of open data evaluation
Open community
Community
Building community …
… is hard work.
Communities
How to make a community
●Get people together
●Organise events (hackathons, (un)conferences, code sprints)
●Be inclusive, go to other events
●Connect people (Chat, Forums, Mailing lists)
●Have fun (Beer)
●Have common target (open data in your country)
●Keep things warm, communicate
