Hi Aimee,
 
I was at the 35c3 meeting where we discussed the need for a content review:

Hi I was there to, I was the person with the LED hat ;-) 

2. long term solution - find good long term solutions for keeping the 
data current and up to date

Maybe implement a kind of refresh option, if its abandoned for more then x time automagic set it to 'inactive'
 
1st stage - help needed with:

b. automatically identifying and flagging dead links on active profiles
and marking them as dead links on profiles

I can program in php/python but are not an expert in (Semantic) wiki, some help here would be appreciated.

c. visit hackerspaces in your area and updating their profile or asking
them to update their profile accordingly - think of this a human
verification to make sure they are still active and run by people (as
opposed to corporate bots)

I can do this for Netherlands and dutch speaking part of Belgium. Other places if I can manage contact them by internet.
I notice for the Dutch hackerspace there are 27 listed, but 13 are 'real' hacerspaces. The remaining are FabLabs, (commercial) makerspaces or just group of friends. Is there a easy way to difference between these groups? There is a [[Category:FabLab]] but as far i can see you cant edit this with the form (and not every fablab use this)

Regards,
Dave Borghuis
