In+ersec+ion for Spatial People

Many of us probably deal with a lot of geodata that significantly evolve over time, the need for geodata versioning mechanisms is clearly a major one in many sectors. About a year ago we mentioned OpenGeo's GeoGit project, and now OpenGeo shared their vision for distributed versioning of geospatial data. This is important stuff.

In addition to this intro, here's the 3-part series:

1. Distributed Versioning for Geospatial, a new approach offers an outline of our vision of geospatial versioning
2. Distributed Versioning Implementation outlines the work we’ve already done
3. Distributed Versioning, Potential Development lays out potential plans for the future

From their introduction: "As opposed to spatial data being be locked-up in a single machine or database, we see a future where it could live in a collaborative infrastructure that can track data’s origin and evolution, much like source code. [...] A distributed version control model can better address such problems as collaborating between users or organization, maintaining authoritative data, and enabling offline, low-bandwidth, or intermittent connectivity."
