Hi everyone, I intend to write a script to complete the information on the japanese train stations nodes. It would - add the «wikipedia» tag if it does not exist - fix the «wikipedia» tags with outdated format (for example: wikipedia:ja = http://...) - complete the names tags from the existing values So any comment would be welcome.
So I think that I would do it like that: - I create an OSM account for this task - I get a recent dump for Japan - Using osmosis, I extract all the nodes having railway=station (about 9000 nodes) - My script will filter the nodes having incomplete information - It will process the filtered nodes list by batches of X nodes (where X is a reasonable number for a commit). I could try to create batches containing nodes in the same area - it will retrieve the latest version of each node (by id) using the API - If the Wikipedia link is missing, it will download the jp WP page (easy, the page name is [station name] + «eki»). If it cannot be retrieved, or if I cannot be sure that the page is a not disambiguation page, I give up - it could check if the coordinates in the WP page (if present) are about the same than the node. If not, wrong station, I give up - if the wikipedia tag is wrong, it can fix it (if the value is an URL, it can set it to the page name) - it will complete the names tags if needed: «name:en» and «name:ja_rm» have the same value. They can also be deduced from «ja_kana» (but it's not always perfect), and vice versa. «name» can be set with the value «name:ja (name:ja_rm)» if these two tags are present. - the modified nodes of a batch will be put in an XML. I could review them in JOSM before submitting them. I have no experience when it comes to mechanical edit in OSM, so any comment is welcome to make it safe, for the both the servers and the existing data. I don't know if it is technically necessary to split the commit in batches. But I thought that it would be nice for manual reviews. My japanese is too bad to write on the jp mailing list :-) Cheers, Fabien _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
