To expand on what I wrote on Twitter, one of the points of open data is to tap into the power of emergence. If your data is available and compelling, then other people will find useful and interesting things to do with it.
That’s the theory, at least. Open data helps create the conditions for emergence, but it’s not sufficient. Without a culture of openness, your data will likely lie fallow. If you already have that culture, you’re lucky. If you don’t, you have to build it. Building culture is hard.
There are lots of ways to build culture. There are no set formulas, and so my rule of thumb is to take every opportunity you can to do it.
That brings me to the original point that provoked this conversation: Should a conference on open data also be open to any participants? No, it doesn’t have to be. No set formulas, right? But it’s an opportunity to build culture, to get people out of the comfort zone of closed. And I generally think that people overrationalize the need to be closed.
The beauty of this little ecosystem we live in is that pockets of closed can beget openness, just as Foo Camp inspired Bar Camp, which launched the unconference movement. That’s what openness is ultimately about.
