Open Source GIS Software

Welcome to the GeoGig project, exploring the use of distributed management of spatial data. GeoGig draws inspiration from Git, but adapts its core concepts to handle versioning of geospatial data. Users are able to import raw geospatial data (currently from Shapefiles, PostGIS or SpatiaLite) in to a repository where every change to the data is tracked. These changes can be viewed in a history, reverted to older versions, branched in to sandboxed areas, merged back in, and pushed to remote repositories.

The promise of SOA leads us down the path of creating, publishing and both statically and dynamically consuming run-time service. These services can be either human consumable (web sites, widgets and/or portlets) or machine consumable (REST, SOAP, JMS, MQ, FTP, RMI, etc) services. The adoption and usage of UDDI has made clear that it is not the answer to the dynamic discovery and consumption model. This Service-Registry project targets the next generation of application and how they will both publish and consume run-time service and propogate registry entries across a network of registries. Further, other registries loose value over time as they eventually get filled with garbage that makes it difficult to discern good entries from defunct entries. Service-Registry is designed to be "self cleaning" keeping the usefulness of registry high. Service-Registry also has a robust federation strategy and implementation to allow registry entries move about the service ecosystem.
