I looked at this page, and I left mostly confused as to what, precisely, "Overture Maps" actually is (or will be). Is it...<p>a) A geospatial data revision control system? [Collaborative Map Building]<p>b) A new way to do geospatial indexing, or some metamanagement layer on top of one or more existing forms of geospatial indexing? [Global Entity Reference System]<p>c) A quality control process, tool, system or review board/certification standard? [Quality Assurance Processes]<p>d) Specific SQL or NoSQL reifications for binding to specific datastores? [Structured Data Schema]<p>You can read into these tea leaves all you want, but at the end of the day, it's all just marketecture with no actual "stuff" behind it. At least as far as you and I as rubes on the Internet are concerned. The page is very, very light on details.<p>Moreover, I am 100% positive that the $3,000 price tag for individuals to just poke your nose in the tent, or $300,000 to actually to have <i>voting rights</i> is about as <i>anti</i>-open source-y as you can get.<p>Is it just me? Is this how people expect good open source results and progress to actually occur?
