Its official. As of Sunday 7th Oct 2007 the OpenStreetMap segment is 410 Gone. It had a brief and at times difficult life sandwiched between nodes and overshadowed by ways. But shall we miss it? I think not. For the uninitiated, OSM moved to the new 0.5 server code at the weekend thanks to the hard work done by Frederik, Gabriel, TomH and others. The data model now consists only of the node and way plus the new Relationships (relation), which offers a whole new data creation experience. The majority of the OSM platform tools have been migrated to support the API v0.5, which is not backwards compatible with v0.4 tools. Both potlatch and JOSM work with the changes although for JOSM you will need to download the latest version.
