schema-builder
This package lets you define and compile OpenStreetMap presets, fields, and other tagging info into the format expected by the iD editor.
The iD Tagging Schema project uses this to manage iD's tags. You can use it to create a custom schema for your own iD instance.
Usage
Building Distribution Data
To validate your source data and compile output files for iD (i.e. when releasing a new schema version):
const schemaBuilder = require('@ideditor/schema-builder');
schemaBuilder.buildDist({
inDirectory: 'data',
interimDirectory: 'interim',
outDirectory: 'dist',
sourceLocale: 'en',
taginfoProjectInfo: {
name: 'IntrepiD',
description: 'iD editor, but adventurous.',
project_url: 'https://example.com/IntrepiD',
contact_name: 'J. Maintainer',
contact_email: '[email protected]'
}
});
The following options are optional:
inDirectory
:string
, The relative directory of the source data files. Defaults todata
.interimDirectory
:string
, The relative directory of files needed during development but not for distribution. Be aware that everything in this directory will be overwritten when building. Defaults tointerim
.outDirectory
:string
, The relative directory of the built data files intended for distribution. Be aware that everything in this directory will be overwritten when building. Defaults todist
.sourceLocale
:string
, The code of the language/locale used for the translatable strings in the data files. Defaults toen
.taginfoProjectInfo
:object
, Project metadata required by TagInfo (Wiki). If this info is not provided, thetaginfo.json
file will not be built. See the schema for more details. The generated taginfo.json will use the following mnemonics to give context to the generated description on taginfo:- 🄿: preset
- 🄵: field
- 🄵🅅: field value
- 🄳: deprecated tag
- 🄳🄳: discarded tag
processPresets
:function(presets)
, An opportunity to edit the built presets.processFields
:function(fields)
, An opportunity to edit the built fields.processCategories
:function(categories)
, An opportunity to edit the built preset categories.listReusedIcons
:boolean
ornumber
, If true, icons used by multiple searchable presets will be listed. If a number, icons used more than that number of times are listed. Defaults tofalse
.
You can also include options from schemaBuilder.fetchTranslations()
in order to
download translation files at the same time as compiling data.
Building Development Data
To validate your source data and compile files needed during development:
const schemaBuilder = require('@ideditor/schema-builder');
schemaBuilder.buildDev({
inDirectory: 'data',
interimDirectory: 'interim',
sourceLocale: 'en'
});
The following options are identical to those for schemaBuilder.buildDist()
:
inDirectory
interimDirectory
sourceLocale
processPresets
processFields
processCategories
listReusedIcons
Validating Data
To validate your source data without compiling anything:
const schemaBuilder = require('@ideditor/schema-builder');
schemaBuilder.validate({
inDirectory: 'data'
});
The following options are identical to those for schemaBuilder.buildDist()
:
inDirectory
processPresets
processFields
processCategories
listReusedIcons
Fetching Translations
To download locale files from Transfiex:
const schemaBuilder = require('@ideditor/schema-builder');
schemaBuilder.fetchTranslations({
outDirectory: 'dist',
sourceLocale: 'en',
translOrgId: 'openstreetmap',
translProjectId: 'intrepid',
translResourceIds: ['presets'],
translReviewedOnly: ['de', 'es']
});
The following options are required:
translOrgId
:string
, The ID of the Transfiex organization where the translation project is hosted.translProjectId
:string
, The ID of the Transfiex project within the organization where the schema resource is translated.
The following options are optional:
translResourceIds
:[string]
, The IDs of the resources to download. Defaults to['presets']
.translCredentials
:{ user: string, password: string }
, Your Transifex API credentials. Defaults to those stored as JSON in atransifex.auth
file in your working directory.translReviewedOnly
:boolean
or[string]
, Iftrue
, only reviewed translations are included. Iffalse
, all translations are included. If an array of locale codes, only reviewed translations are included for those specified locale codes, while all translations are included for the remaining locales.outDirectory
:string
, Same as theoutDirectory
option forschemaBuilder.buildDist()
.sourceLocale
:string
, Same as thesourceLocale
option forschemaBuilder.buildDist()
.
Source Files
Your inDirectory
folder (data
by default) should contain your source files with this structure:
data/
categories/
category1.json
category2.json
...
fields/
field1.json
field2.json
...
presets/
preset1.json
preset2.json
...
defaults.json
deprecated.json
discarded.json
The format for each file is defined in the schemas
directory.
Presets
A preset represents a specific type of map feature. For example, presets can exist for parks, restaurants, drinking water fountains, buildings, railway tracks, and many more feature types.
iD editor preset and field types are defined in JSON
files located under the data/presets
folder.
Preset Files
Presets are defined in JSON files located under data/presets
. They're organized in a
directory hierarchy based on OSM key/value pairs. For example, the preset that matches
the tag leisure=park
is in the file data/presets/leisure/park.json
.
Preset Schema
A basic preset is of the form:
{
// Display name for this feature type in the `sourceLocale` language.
"name": "Produce Stand",
// Aliases are synonyms of the preset's name - this is for alternative
// names a preset might also be known as
"aliases": [
"Farm Shop",
"Farm Stand"
]
// Terms are additional search terms for the preset - these are added to
// fuel the search functionality. searching for 'vegetables' will bring
// up this 'farm shop' preset
"terms": [
"fresh food",
"fruits",
"greengrocer",
"orchard",
"organics",
"vegetables"
],
// Tags that are added to the feature when selecting the preset,
// and also used to match the preset against existing features.
// You can use the value "*" to match any value.
"tags": {
"shop": "farm"
},
// The geometry types for which this preset is valid.
// options are point, area, line, and vertex.
// vertices are points that are parts of lines, like the nodes in a road
// lines are unclosed ways, and areas are closed ways
"geometry": [
"point", "area"
]
// The icon in iD which represents this feature.
"icon": "maki-shop",
// The names of fields that will appear by default in the editor sidebar.
// See the fields documentation for details of what's valid here.
"fields": [
"{shop}",
"organic"
],
// The names of fields that the user can add manually. These will also
// appear if the corresponding tags are present.
"moreFields": [
"produce"
]
}
The complete JSON schema for presets can be found in schemas/preset.json
Preset Properties
name
The primary name of the feature type.
Upon merging into the main
branch, this is sent to Transifex for translating to other localizations. Changing the name of an existing preset will require it to be re-translated to all localizations.
A preset can optionally reference the label of another by using that preset's name contained in brackets, like {preset}
. In which case the presets's terms and aliases are also automatically sourced from that other field. This is for example useful for regional presets which should get the same labels as the preset they are based on.
This property is required. There is no default.
aliases
A list of synonyms for the preset's name
. These are alternative terms a preset might also be known as. For example, Port could be added as an alias to the Harbor preset. Terms which describe a specific sub-type of a preset should not be added as an alias (e.g. Barber Shop should not be added as an alias to the Hairdresser preset).
terms
A list of additional search terms or keywords for the preset. These might be names which describe a subset of the preset's features, or simply related terms a user might enter when searching for the preset.
geometry
An array of possible geometry types that a feature must have in order to match this preset.
point
: an OSM node that is not a member of any wayvertex
: an OSM node that is a member of one or more waysline
: an OSM way that is not an areaarea
: an OSM way that is closed/circular (the first and last nodes are the same) or atype=multipolygon
relationrelation
: an OSM relation
Closed ways can be treated as both line
or area
geometry. If a preset allows both, iD will add an additional area=yes
tag when choosing the preset for an area feature.
The geometry types should be listed in order of preference. For example, the preset for leisure=swimming_pool
lists area
before point
.
This property is required. There is no default.
tags
An object with the "key": "value"
tags a feature must have to match this preset. A "*"
wildcard value can be set to have this preset match any value for that key.
A feature can only match one preset even if its tags and geometry could technically match more than one. iD will pick the best match based on matchScore
, the number of tags, and the use of wildcard values.
This property is required. There is no default.
addTags
The tags that are added to the feature when selecting this preset. Defaults to tags
. If needed, this property will typically be a superset of tags
.
iD's validator will recommend that users add missing tags from addTags
to matching features. For example, the Bridge preset has these properties:
"tags": {
"man_made": "bridge"
},
"addTags": {
"man_made": "bridge",
"layer": "1"
},
When adding a feature with this preset, it will be given the tags man_made=bridge
and layer=1
. The user could then change layer
to 3
, for instance, and the feature would still match the preset because it still has man_made=bridge
. If the user removes the layer
tag altogether, iD will recommend adding it back with a value of 1
.
removeTags
The tags that are removed from the feature when deselecting this preset. Defaults to addTags
or if this is also not defined, to tags
.
fields
/moreFields
Both these properties are arrays of field paths (e.g. description
or generator/type
).
fields
are shown by default and moreFields
are shown if manually added by the
user or if a matching tag is present. Note that some fields have a prerequisiteTag
property that limits when they will be shown.
A preset can reference the fields of another by using that preset's name contained in
brackets, like {preset}
. For example, {shop}
in presets/shop/books.json
references and extends the fields
of presets/shop.json
. When subfolders are used, the format is {shop/books}
to reference the properties of the shop/books.json
.
"fields": [
"{shop}",
"internet_access"
],
"moreFields": [
"{shop}",
"internet_access/fee",
"internet_access/ssid"
],
"tags": {
"shop": "books"
}
If fields
or moreFields
are not defined, the values of the preset's "parent"
preset are used. For example, shop/convenience
automatically uses the same
fields as shop
.
In both explicit and implicit inheritance, fields for keys that define the
preset via tags
are generally not inherited, even when specified by the parent explicity.
E.g. the shop
field is not inherited by shop/…
presets.
This can be overwritten by adding the field explicitly like "fields": [ "shop", "{shop}" ],
icon
An icon representing a preset, e.g. "icon": "temaki-power_tower"
(Example). More information about available icon sets and usage of icons can be found on the icons subpage.
imageURL
The URL of a remote image file. This does not fully replace icon
—both may be shown in the UI.
For example, imageURL
is used to specify the logos of brand presets from the name-suggestion-index.
Bitmap images should be at least 100×100 px² to look good on high-resolution screens.
searchable
Deprecated or generic presets can include the property "searchable": false
.
This means that they will be recognized by iD when editing existing data,
but will not be available as an option when adding new features.
By convention, unsearchable presets have filenames that begin with an underscore
(e.g. data/presets/landuse/_farm.json
)
matchScore
A number that ranks this preset against others that match the feature.
For example, a feature with amenity=cafe
and building=commercial
will match the Cafe preset instead of the Commercial Building preset because Commercial Building has a lower matchScore
.
The default is 1.0
.
locationSet
An object with the identifiers of regions where this preset should or shouldn't be shown. By default, presets are available everywhere.
See the location-conflation package for details.
"locationSet": {
"include": ["US"],
"exclude": ["PR", "VI"]
}
replacement
The ID of a preset that is preferable to this one. iD's validator will flag features matching this preset and recommend that the user upgrade the tags.
When possible, use deprecated.json
instead to specify upgrade paths for old tags. This property is meant for special cases, such as upgrades with geometry requirements.
reference
A key and optionally a value to link to the wiki documentation for this preset. Only necessary if the preset consists of several tags.
For example,
"reference": {
"key": "tower:type",
"value": "communication"
}
Fields
Fields are reusable form elements that can be associated with presets.
Field Files
Fields are defined in JSON files located under data/fields
.
The field files are typically named according to their associated OSM key.
For example, the field for the tag sport=*
is stored in the file
data/fields/sport.json
. When a field has multiple versions that
depend on which preset is active, we add a suffix to the filename:
(sport.json
, sport_ice.json
, sport_racing_motor.json
).
Some keys in OSM are namespaced using colons (':'). Namespaced fields
are nested in folders according to their tag.
For example, the field for the tag piste:difficulty=*
is stored in the file
data/fields/piste/difficulty.json
.
Field Schema
{
"key": "cuisine",
"type": "combo",
"label": "Cuisine"
}
The complete JSON schema for fields can be found in schemas/field.json
Field Properties
label
A sort desciption or caption of the field.
A field can optionally reference the label of another by using that field's name contained in brackets, like {field}
. In which case the field's terms are also automatically sourced from that other field. This is for example useful when there are multiple variants of fields for the same tag, which should all have the same labels.
type
A string specifying the UI and behavior of the field. Must be one of the following values.
Text fields
text
- Basic single line text fieldnumber
- Text field with up/down buttons for entering numbers (e.g.width=*

or*:forward
/*:backward
) tags on a linear way. This field was namedcycleway
untilv5.3.0
. This field type requires that both thekeys
andkey
properties are specified (key
for the common (e.g.:both
) subtag of this field andkeys
for the directional (e.g.:left
/:right
) subtags).
Checkboxes

, e.g.cutting
manual
- The field is only added by iD programmatically as needed, e.g.restrictions
key
/keys
The key
property names the OSM tag key that the field will edit. Some fields, like the address
field, operate on more than one tag: These expect an array of keys in the keys
property. The following table lists which field types accept which properties:
field type | key
| keys
| description | example
---------- | ----- | ------ | ----------- | -------
text
, number
, email
, url
, tel
| :heavy_check_mark: | optional | Optionally, these fields can match multiple tag keys
of an OSM object: which is useful to support OSM tags which have more than one established tag key like phone
and contact:phone
.[^1] | "key": "phone", "keys": ["phone", "contact:phone"]
address
| :heavy_check_mark: | :heavy_check_mark: | keys
must contains all possible subtags to be used in the address field and key
must contain the tag key prefix (e.g. addr
). | "key": "addr", "keys": ["addr:city", "addr:street", …]
wikipedia
, wikidata
| :heavy_check_mark: | :heavy_check_mark: | As the values of these two fields should be updated in sync by the editor, the keys
should always contain both the respective wikipedia and wikidata keys. | "key": "flag:wikidata", "keys": ["flag:wikidata", "flag:wikipedia"]
directionalCombo
| :heavy_check_mark: | :heavy_check_mark: | For directional fields, the key
is the tag to use when the OSM feature has the same attributes in both directions, while the keys
are the two tags for the individual directions. | "key": "cycleway", "keys": ["cycleway:right", "cycleway:left"]
access
| :x: | :heavy_check_mark: | keys
lists all access tags to consider in the field. | "keys": ["access", "foot", "bicycle", …]
localized
| :heavy_check_mark: | :x: | key
specified the main tag, which will also be used as the tag key prefix for localized versions of the tag (i.e. the name
field will also display contents of the tags name:*
). | "key": "name"
multiCombo
| :heavy_check_mark: | :x: | This field allows to toggle multiple yes/no
subtags which share a common tag prefix specified in the field's key
. | "key": "recycling:"
manyCombo
| :x: | :heavy_check_mark: | Similar to the multiCombo
field, but here the keys
property contains the full list of OSM tag keys which the options of the field should correspond to. | "keys": ["hiking", "bicycle", …]
structureRadio
| :x: | :heavy_check_mark: | Like the radio
field, but operates on multiple tags: Selecting an option will remove the tag for the previously active option. | "keys": ["bridge", "tunnel", …]
restrictions
| :x: | :x: | A special field which does not operate on tags, therefore does not need key
or keys
. |
all other fields | :heavy_check_mark: | :x: | A regular field which only operates on a single tag. | "key": "oneway"
[^1]: The intended behaviour of a field with alternative keys
is the following: If an OSM feature does not yet have a tag of the given keys
, the supplied key
will be used; if a feature has a single tag which matches a key from the keys
, it should be used by the field; if a feature has multiple tags matching a key from the keys
alternatives, the field should update them simultaneously and display a multiple/conflicting values message if necessary.
universal
If a field definition contains the property "universal": true
, this field will
appear in the "Add Field" list for all presets
geometry
If specified, only show the field for this kind of geometry. Should contain
one of point
, vertex
, line
, area
.
default
The default value for the field. For example, the building_area.json
field
will automatically add the tag building=yes
to certain presets that are
associated with building features (but only if drawn as a closed area).
{
"key": "building",
"type": "combo",
"default": "yes",
"geometry": "area",
"label": "Building"
}
placeholder
The text which should be shown in a field's input box when no value has been entered yet. This text is shown as a grayed-out text and can be used to give the user some examples of what to enter in the respective field.
A field can optionally reference the placeholder text of another by using that field's name contained in brackets, like {field}
. In which case the field's terms are also automatically sourced from that other field. This is for example useful when there are multiple variants of fields for the same tag, which should all have the same labels.
options
Combo field types can provide dropdown values in an options
array.
The user can pick from any of the options, or type their own value.
{
"key": "diaper",
"type": "combo",
"label": "Diaper Changing Available",
"options": ["yes", "no", "room", "1", "2", "3", "4", "5"]
}
strings
The strings
object contains values that the field wants to be translated on Transifex.
Combo field types can accept key-label pairs in the options
value of the strings
property.
These values populate the options
property if it isn't otherwise specified.
If autoSuggestions
is true
(as per default), then raw and labeled values might be mixed
in the dropdown suggestions.
{
"key": "smoothness",
"type": "combo",
"label": "Smoothness",
"placeholder": "Thin Rollers, Wheels, Off-Road...",
"strings": {
"options": {
"excellent": "Thin Rollers: rollerblade, skateboard",
"good": "Thin Wheels: racing bike",
"intermediate": "Wheels: city bike, wheelchair, scooter",
"bad": "Robust Wheels: trekking bike, car, rickshaw",
"very_bad": "High Clearance: light duty off-road vehicle",
"horrible": "Off-Road: heavy duty off-road vehicle",
"very_horrible": "Specialized off-road: tractor, ATV",
"impassable": "Impassable / No wheeled vehicle"
}
}
}
Checkbox field tyes use the options keys to specify the values of the OSM tag corresponding to the different states of the checkbox input element, in the following order:
- fields of type
check
: unset state (must use the optionundefined
), checked state, unchecked state (example) - fields of type
defaultCheck
: unchecked state (must use the optionundefined
), checked state (example)
stringsCrossReference
An optional property to reference to the strings of another field, indicated by using that field's name contained in brackets, like {field}
. This is for example useful when there are multiple variants of fields for the same tag, which should all use the same strings.
autoSuggestions
For combo fields, the most common tag values will be fetched from TagInfo and shown
in the dropdown list if autoSuggestions
is true
. The default is true
.
customValues
For combo fields, the user can type a custom value in addition to choosing any shown
in the dropdown list if customValues
is true
. The default is true
.
snake_case
For combo fields, spaces are replaced with underscores in the tag value if snake_case
is true
. The default is true
.
caseSensitive
For combo fields, case-sensitive field values are allowed if caseSensitive
is true
. The default is false
.
minValue
For number fields, the lowest valid value. There is no default.
maxValue
For number fields, the greatest valid value. There is no default.
increment
For number fields, the amount the stepper control increases or decreases the value. The default is 1
.
prerequisiteTag
An object defining the tags the feature needs before this field will be displayed. It may have this property:
key
: The key for the required tag.
And may optionally be combined with one of these properties:
value
: The value that the key must have.valueNot
: The value that the key must not have.
Alternatively, the object may contain a single property:
keyNot
: The key that must not be present.
For example, this is how we show the Internet Access Fee field only if the feature has an internet_access
tag not equal to no
.
"prerequisiteTag": {
"key": "internet_access",
"valueNot": "no"
}
If a feature has a value for this field's key
or keys
, it will display regardless of the prerequisiteTag
property.
locationSet
An object with the identifiers of regions where this field should or shouldn't be shown. By default, fields are available everywhere.
See the location-conflation package for details.
"locationSet": {
"include": ["US"],
"exclude": ["PR", "VI"]
}
urlFormat
For identifier
fields, the permalink URL of the external record. It must contain a {value}
placeholder where the tag value will be inserted. For example:
"urlFormat": "https://geonames.usgs.gov/apex/f?p=gnispq:3:::NO::P3_FID:{value}"
pattern
For identifier
fields, the regular expression that valid values are expected to match to be linkable.
icons
For combo fields, the icons
object might contain the name of icons which represent the different values of the field. More information about available icon sets and usage of icons can be found on the icons subpage.
Combo field types can accept key-label pairs in the options
value of the strings
property.
{
"key": "crossing:markings",
"type": "combo",
"label": "Crossing Markings",
"icons": {
"zebra": "iD-crossing_markings-zebra",
"lines": "iD-crossing_markings-lines",
…
}
}
iconsCrossReference
An optional property to reference to the icons of another field, indicated by using that field's name contained in brackets, like {field}
. This is for example useful when there are multiple variants of fields for the same tag, which should all use the same icons.
Deprecations
Use deprecated.json
(Example, Schema) to specify tag deprecations.
Usage example: iD Editor will show an information panel that informs users about deprecated tags and an update-tag-action.
Example: Default Case
To update a specific tag to a specific new tag
{
"old": {"foo": "value"},
"replace": {"bar": "value"}
},
Example: Change the key, keep the value
{
"old": {"foo": "*"},
"replace": {"bar": "$1"}
},
Example: Delete a tag
{
"old": {"content": "unknown"}
},
