### Special tag renderings
|
|
|
|
In a tagrendering, some special values are substituted by an advanced UI-element. This allows advanced features and visualizations to be reused by custom themes or even to query third-party API's. General usage is `{func_name()}`, `{func_name(arg, someotherarg)}` or `{func_name(args):cssStyle}`. Note that you _do not_fcs need to use quotes around your arguments, the comma is enough to separate them. This also implies you cannot use a comma in your args
|
|
### all_tags

### import_button
|
|
|
|
This button will copy the data from an external dataset into OpenStreetMap. It is only functional in official themes but can be tested in unofficial themes.
|
|
|
|
If you want to import a dataset, make sure that:
|
|
|
|
1. The dataset to import has a suitable license
|
|
2. The community has been informed of the import
|
|
3. All other requirements of the [import guidelines](https://wiki.openstreetmap.org/wiki/Import/Guidelines) have been followed
|
|
|
|
There are also some technicalities in your theme to keep in mind:
|
|
|
|
1. The new point will be added and will flow through the program as any other new point as if it came from OSM.
|
|
This means that there should be a layer which will match the new tags and which will display it.
|
|
2. The original point from your geojson layer will gain the tag '_imported=yes'.
|
|
This should be used to change the appearance or even to hide it (eg by changing the icon size to zero)
|
|
3. There should be a way for the theme to detect previously imported points, even after reloading.
|
|
A reference number to the original dataset is an excellen way to do this
|
|
|
|
|
|
name | default | description
|
|
------ | --------- | -------------
|
|
tags | undefined | Tags to copy-specification. This contains one or more pairs (seperated by a `;`), e.g. `amenity=fast_food; addr:housenumber=$number`. This new point will then have the tags `amenity=fast_food` and `addr:housenumber` with the value that was saved in `number` in the original feature. (Hint: prepare these values, e.g. with calculatedTags)
|
|
text | Import this data into OpenStreetMap | The text to show on the button
|
|
icon | ./assets/svg/addSmall.svg | A nice icon to show in the button
|
|
minzoom | 18 | How far the contributor must zoom in before being able to import the point
|
|
|
|
#### Example usage
|
|
|
|
`{import_button(,Import this data into OpenStreetMap,./assets/svg/addSmall.svg,18)}`
|
|
### multi_apply
|
|
|
|
A button to apply the tagging of this object onto a list of other features. This is an advanced feature for which you'll need calculatedTags

------ | --------- | -------------
|
|
feature_ids | undefined | A JSOn-serialized list of IDs of features to apply the tagging on

|
keys | undefined | One key (or multiple keys, seperated by ';') of the attribute that should be copied onto the other features.

text | undefined | The text to show on the button

|
overwrite | undefined | If set to 'true', the tags on the other objects will always be overwritten. The default behaviour will be to only change the tags on other objects if they are either undefined or had the same value before the change
|
|
|
|
#### Example usage
|
|
|
|
{multi_apply(_features_with_the_same_name_within_100m, name:etymology:wikidata;name:etymology, Apply etymology information on all nearby objects with the same name)} Generated from UI/SpecialVisualisations.ts |
