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 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

Using expanded syntax
Instead of using {"render": {"en": "{some_special_visualisation(some_arg, some other really long message, more args)} , "nl": "{some_special_visualisation(some_arg, een boodschap in een andere taal, more args)}}, one can also write
{
"render": {
"special": {
"type": "some_special_visualisation",
"argname": "some_arg",
"message": {
"en": "some other really long message",
"nl": "een boodschap in een andere taal"
},
"other_arg_name": "more args"
},
"before": {
"en": "Some text to prefix before the special element (e.g. a title)",
"nl": "Een tekst om voor het element te zetten (bv. een titel)"
},
"after": {
"en": "Some text to put after the element, e.g. a footer"
}
}
}
In other words: use { "before": ..., "after": ..., "special": {"type": ..., "argname": ...argvalue...}. The args are in the special block; an argvalue can be a string, a translation or another value. (Refer to class RewriteSpecial in case of problems)

Example usage of plantnet_detection
{plantnet_detection(image,mapillary,image,wikidata,wikimedia_commons,image,image)}
tag_apply
Shows a big button; clicking this button will apply certain tags onto the feature.
The first argument takes a specification of which tags to add. These can either be a tag to add, such as amenity=fast_food or can use a substitution, e.g. addr:housenumber=$number. This new point will then have the tags amenity=fast_food and addr:housenumber with the value that was saved in number in the original feature.
If a value to substitute is undefined, empty string will be used instead.
This supports multiple values, e.g. ref=$source:geometry:type/$source:geometry:ref
Remark that the syntax is slightly different then expected; it uses '$' to note a value to copy, followed by a name (matched with [a-zA-Z0-9_:]*). Sadly, delimiting with {} as these already mark the boundaries of the special rendering...
Note that these values can be prepare with javascript in the theme by using a calculatedTag
name

description
tags_to_apply

maproulette_id
undefined
If specified, this maproulette-challenge will be closed when the tags are applied. This should be the ID of the task, not the task_id.
Example usage of tag_apply
{tag_apply(survey_date=$_now:date, Surveyed today!)}, `{tag_apply(addr:street=$addr:street, Apply the address, apply_icon.svg, _closest_osm_id)
import_button
This button will copy the point from an external dataset into OpenStreetMap
Note that the contributor must zoom to at least zoomlevel 18 to be able to use this functionality. It is only functional in official themes, but can be tested in unoffical themes.
Specifying which tags to copy or add
The argument `tags` of the import button takes a `;`-seperated list of tags to add (or the name of a property which contains a JSON-list of properties).
These can either be a tag to add, such as amenity=fast_food or can use a substitution, e.g. addr:housenumber=$number. This new point will then have the tags amenity=fast_food and addr:housenumber with the value that was saved in number in the original feature.
If a value to substitute is undefined, empty string will be used instead.
This supports multiple values, e.g. ref=$source:geometry:type/$source:geometry:ref
Remark that the syntax is slightly different then expected; it uses '$' to note a value to copy, followed by a name (matched with [a-zA-Z0-9_:]*). Sadly, delimiting with {} as these already mark the boundaries of the special rendering...
Note that these values can be prepare with javascript in the theme by using a calculatedTag
Importing a dataset into OpenStreetMap: requirements
If you want to import a dataset, make sure that:
- The dataset to import has a suitable license
- The community has been informed of the import
- All other requirements of the import guidelines have been followed
There are also some technicalities in your theme to keep in mind:
- The new feature 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.
- The original feature 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)
- 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 excellent way to do this
- When importing ways, the theme creator is also responsible of avoiding overlapping ways.
Disabled in unofficial themes
The import button can be tested in an unofficial theme by adding test=true or backend=osm-test as URL-paramter. The import button will show up then. If in testmode, you can read the changeset-XML directly in the web console. In the case that MapComplete is pointed to the testing grounds, the edit will be made on https://master.apis.dev.openstreetmap.org

import_way_button
This button will copy the data from an external dataset into OpenStreetMap, copying the geometry and adding it as a 'line'
Note that the contributor must zoom to at least zoomlevel 18 to be able to use this functionality. It is only functional in official themes, but can be tested in unoffical themes.
Specifying which tags to copy or add
The argument `tags` of the import button takes a `;`-seperated list of tags to add (or the name of a property which contains a JSON-list of properties).
These can either be a tag to add, such as amenity=fast_food or can use a substitution, e.g. addr:housenumber=$number. This new point will then have the tags amenity=fast_food and addr:housenumber with the value that was saved in number in the original feature.
If a value to substitute is undefined, empty string will be used instead.
This supports multiple values, e.g. ref=$source:geometry:type/$source:geometry:ref

auto_apply
A button to run many actions for many features at once. To effectively use this button, you'll need some ingredients:

- A host feature to place the auto-action on. This can be a big outline (such as a city). Another good option for this is the layer
- current_view
- Then, use a calculated tag on the host feature to determine the overlapping object ids
- At last, add this component
