I'll need output in the following form: tag-key, number of changesets, nodes, relations and ways this key is used on, number of distinct values tag-value, the tag-key this value belongs to, number of changesets, nodes, relations and ways this value is used on Additionally the following information would be nice: key/key combinations and how often these two keys are used in together on changesets, nodes, relations and ways To avoid hitting the database every time a tag is processed I cache the information in a Map in memory. Unfortunately I only have my (t)rusty FreeBSD box with an Dual Core Athlon and 3 GB of RAM. The cache-maps don't fit in memory so I'm looking for a solution to swap this to disk. Additional points for ideas on how to process the daily-diffs to keep the data current :) I need the old and new data for changesets, nodes, relations and ways to process deletions and changes in tags. I think I could write a Osmosis plugin for ths...but that's a problem for another day :) Cheers, Lars _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
