Thanks for all the responses, really interesting and so much information!
We have a new developer in our IT team at the CIC who is working on a django based app for finance and accounting management (to handle dual currency and other aspects of alternate economies!)… I will ask if he is aware of sensorica and see if it helps to share this information with him.
About tiles, I’m not sure if this is freemium or how open, but I hear mapbox is good. Another django based crowdfunded platform is “macadjan” which we used to create the site I wrongly linked in my last post: http://map.cooperativaintegral.cat/map/
About how to come to agreements, I think the first building block is a shared document area and editing system like collaborative work using owncloud, a versioning system like git and live collaborative editing using titanpad or co-ment could allow for share maintenance of different versions of a proposed standard with different sub areas for fields that are being discussed or refined.
The second aspect is to have a series of in-person or networked meetings where people can decide on tricky areas or directions and reach consensus on publishing a version of this. This could coincide with mapjams or other distributed events.
And finally, I generally find there are varying levels of time and ability across different groups, so it’s important to get the more able ones to help the less so, and probably have someone able to promote a basic level of adherence to whatever software or interfaces we would then recommend people use so they can adopt these standards.
I hope that makes sense, but I think in a couple of years it would leave us with a basic level of quality and adherence to the standards across all initial participants. When I worked in interoperability for learning resources with JISC in the UK there was a lot of this happening in UK academia in bringing together different platforms that had emerged organically over the years, so perhaps there’d be interest from people involved in that: www.ariadne.ac.uk/issue62/cetis-stds-2010-rpt (old-ish article on the state of things) and http://www.jiscdigitalmedia.ac.uk/guide/putting-things-in-order-links-to-metadata-schemas-and-related-standards ( a list of links to different interoperability schemas). At the time we used openarchives (OAI-PHM) as a way of distributing this metadata across all participating databases equally. Hope that helps!
All the best,
