OSMdoc
OSMdoc (osmdoc.com) is a tag tracking system for OpenStreetMap, displaying various usage stats. It's inspired by Tagwatch. You may also want to look at Tagstat for another Tagwatch interface with more up to date data, or the new Taginfo service.
Status
The data currently available online is taken from the planet.osm dump from 12.08.2009.
A new version of OSMdoc is in the works. The release date is as of yet unknown. You may follow the development on the blog. There you can also find contact information if you have any further questions. I also try to reply on the discussion page.
Development
- The current version is written in Python using Django (djangoproject.com) and PostgreSQL as a backend
- The source code for the version currently (as of February 2010) online is not available
- Source code for the new version will be made available
Available sources
The new OSMdoc version is very modular. It is split into multiple projects each doing only a simple thing and I plan to release those projects when they are in a state to be shown to the public.
- osm-domain: A project that introduces an Avro schema for all the OSM elements. This is the basic model and data transfer schema the backend tools for OSM use. Avro provides a very fast and very compact way to serialize this data (Apache License, Version 2.0)
- osm-utils: A project that provides a few utility methods that are useful for dealing with OpenStreetMap data (coordinates and timestamps)
- osm-reader: A project to parse .osm XML files. This project uses the openstreetmap-domain classes and sends the results to a RabbitMQ queue
- osm-hbase-utils: A project providing utility classes for OSM and OSMdoc related HBase database access
