Hi! There are a few new functions available in taginfo: - "Similar" tab in key view and "Similar keys" report. Similarity in this context means one key is a substring of the other (ignoring case) or the Levenshtein distance between keys is <= 3. Keys with three characters or less are ignored. The "Similar" tab reports all those keys similar to the given key, the "Similar keys" report only shows rarely used keys that are very similar to common keys. Currently there is no way of tuning the parameters for these checks. Please tell me if you are having problems with the settings for your extract. - "Historic development" report showing numbers of unique keys, tags, and relation types over time. This report uses data accumulated over time in the taginfo-history.db database by each taginfo update run. This data wasn't used until now.
To ease the transition, the "Similar keys" report will show a warning if the data needed for the report is not available. After the next update run it should just work. The "Similar" tab will only work once the config setting 'user_interface.key_page.show_tab_similar' is set to 'true'. By default it is 'false'. To update to this version: - Update taginfo from github. - Call 'make' in the 'tagstats' directory. There will be an additional binary called 'similarity'. Set 'sources.db.bindir' to wherever that binary is. The default will just access that 'tagstats' directory, but you can change that if you prefer to have the binary somewhere else. - Run the update as usual. - If the update ran through properly, there are two new tables in the 'taginfo-db.db' called 'similar_keys' and 'similar_keys_common_rare'. - Set config 'user_interface.key_page.show_tab_similar' to 'true'. - Restart server. The main taginfo site should have the updates tomorrow.
