[Talk-gb-westmidlands] Schools Project
Hi everyone I didn't realise just how poor our schools data is! It looks good on the standard map but Robert's tool just amazes me about how much work there is to do even in what we thinkof as well-mapped areas. I'm concentrating on tidying up South Birmingham data and Dudley, with a few forays into Herefordshire and Warwickshire to vary the mix. Great to see a project really take off at last!

For settlements where there > is a node and polygon (way or relation) I prefer the node. wikidata items for settlements are very often actually administrative objects in osm, because of the preference for official sources used for Wikipedia (wikidata started by creating an object for every article AFAIK) Is this planned as an actual "mass import", and not every item will be looked at by a human before being uploaded? IMHO it would be better to provide the results of your analysis in small chunks for the local community to be imported "by hand". cheers Martin ___ Talk-gb-westmidlands mailing list Talk-gb-westmidlands@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb-westmidlands

I have started some time ago to add wikidata tags manually myself and have found that there are a few problems to be careful about. Will you be checking the matches you have found to see if there would be contradictions between single wikidata statements and current OSM tags, that will require reorganization of either the OSM object or the wikidata object? "Partial" matches are not so uncommon, e.g. you could have a wikidata object referring to a museum and an OSM object referring to the building housing the museum (or the other way round). Another field of similar but not identical objects can happen with places (and sub-places like quarters), where one of the DBs is referring to the administrative entity and the other to the geographical entity (or only one of the DBs is referring to both while the other has it split over 2 objects).

Re: [Talk-gb-westmidlands] [Imports] Review plan for adding 1, 164 wikidata tags in the West Midlands
In the case of a museum which is tagged as a node, inside a building closedway, I would be inclined to give both the node and the building the same Wikidata tag. I created Lua code which can be included on a Wikipedia page, which uses Overpass API to show where that 'museum' is mapped on Openstreetmap. https://en.wikipedia.org/wiki/Module:OSM At the moment I'm adding wikidata tags to railway stations in Belgium (Thanks to Simon04, who made doing so a bit more practical: THANKS), so I add the same wikidata identifier to both the building=train_station and the node railway=station, and sometimes to the nearby bus stops as well, if they have station in their names. That way, somebody who uses the script, will get to see all the OSM objects that are related to the railway station. At some point it may happen that the separate bus stops will have wikidata items of their own, at that time, they can be updated in OSM and their relation to the station can then probably be found in Wikidata. It's time consuming, but I tend to do this one by one. There are often things that can be mapped in better ways around those stations. What we do need, is a way to fetch wikidata items based on their coordinates in the Wikipedia plugin, now only Wikpedia articles of the language set in the preferences are retrieved.

[Talk-gb-westmidlands] Review plan for adding 1, 164 wikidata tags in the West Midlands
I've written software to match geographic objects in OSM with Wikidata items. Members of the England West Midlands community have asked me to add Wikidata tags to OSM in the West Midlands. I have produced a list of objects to modify, there are 1,164 of them in 44 categories. Wikidata identifiers are look like Q2256, a Q followed by a number. The tags I plan to add will look will look like this: wikidata=Q2256 Wiki page: http://wiki.openstreetmap.org/wiki/Wikidata The matching is based on finding OSM objects with nearby Wikidata items and comparing the names and tags in OSM with labels and aliases in Wikidata. My plan is to add these tags using the API, one changeset per category. Here is a list of matches grouped by category with links to Wikidata, Wikipedia and OSM for each match. https://edwardbetts.com/osm-wikidata/west_midlands/2016-01-16.html This is the list of Wikidata tags that I actually plan to add: https://edwardbetts.com/osm-wikidata/west_midlands/matches_2016-01-16.txt This second lists has duplicates removed. I've also removed any OSM objects that already have a wikidata tag. Wikidata is licensed as public domain or CC0. I'm not importing any location data from Wikidata, just the Wikidata identifier. There are 44,559 existing wikidata tags in the OSM database. I've added an entry to the Import Catalogue in the "Ongoing Imports, Semi-Automated" section. http://wiki.openstreetmap.org/wiki/Import/Catalogue#Ongoing_Imports.2C_Semi-Automated If this upload is successful I plan to repeat the process for other regions in the UK. Then gradually expand to other parts of the world. The matching software is in a reasonably tidy state, after a bit more clean up I will share it for others to review and contribute.
