Each category file contains an Array of items that belong to that category.

The items can include:

  • "Normal" items - items representing brands, flags, routes, or other map features.
  • Templates - placeholders that will expand all the normal items from another source category, but modify the source tags to fit the destination category.

You can include both normal and template items in the same items Array.

Normal Items

"items": [
  …
  {
    "displayName": "McDonald's",
    "id": "mcdonalds-658eea",
    "locationSet": {"include": ["001"]},
    "tags": {
      "amenity": "fast_food",
      "brand": "McDonald's",
      "brand:wikidata": "Q38076",
      "cuisine": "burger",
      "name": "McDonald's"
    }
  },
  …

Normal item properties:

displayName

Required yes
Type String
Example "McDonald's"

The displayName can contain anything, but it should be a short text appropriate for display in lists or as preset names in editor software. This is different from the OpenStreetMap name tag.

The displayName should be written in the local language of the item, and the displayName value must be unique within a category file.

By convention, if you need to disambiguate between multiple brands with the same name, we add text in parenthesis. (See Identical names, different entities for additional information.) Here there are 2 items named "Target", but they have been assigned different display names to tell them apart.

In brands/shop/department_store.json:

"items": [
  …
  {
    "displayName": "Target (Australia)",
    "id": "target-c93bbd",
    "locationSet": {"include": ["au"]},
    "tags": {
      "brand": "Target",
      "brand:wikidata": "Q7685854",
      "name": "Target",
      "shop": "department_store"
    }
  },
  {
    "displayName": "Target (USA)",
    "id": "target-592fe0",
    "locationSet": {"include": ["us"]},
    "tags": {
      "brand": "Target",
      "brand:wikidata": "Q1046951",
      "name": "Target",
      "shop": "department_store"
    }
  },
  …

id

Required no (generated automatically)
Type String
Example "mcdonalds-658eea"

Each item has a unique id generated for it. When adding a new item, you don't need to add an id. Running npm run build after modifying a data file will generate the id for the new data automatically. You can run npm run build before submitting your pull request if you'd like, but this is completely optional. If you don't know how to run npm run build, don't worry: maintainers routinely perform this operation on the index and can generate the id for you.

The identifiers are stable unless the name, key, value, or locationSet change.

locationSet

Required yes
Type Object {}

Each item requires a locationSet to define where the item is available. You can define the locationSet as an Object with include and exclude properties:

"locationSet": {
  "include": [ Array of locations ],
  "exclude": [ Array of locations ]
}

The "locations" can be any of the following:

  • Strings recognized by the country-coder library.
    These include ISO 3166-1 two- or three-letter country codes, UN M49 numeric codes, and supported Wikidata QIDs.
    Examples: "de", "001", "conus", "gb-sct", "Q620634"
    👉 A current list of supported codes can be found at https://ideditor.codes
    👉 See Regional Features for country subdivisions, such as US States and international regions.

  • The id values of custom .geojson features (see Feature Files for details). Existing features can be found under the features/* folder of this project. If you want to use your own features, you need to add the new features to the features/* folder as part of your pull request.
    Each feature must have an id that ends in .geojson. Running npm run build will automatically generate and add an id to the feature if an id is not already specified.
    Examples: "de-hh.geojson", "us-nj.geojson"

  • Circular areas defined as a [longitude, latitude, radius?] Array.
    longitude and latitude are the coordinates of the area's center point. radius is specified in kilometers and is optional. If radius is not specified, the area will default to a 25km radius around the center point.
    Examples: [8.67039, 49.41882], [-88.3726, 39.4818, 32]

locationSet Tips:

matchNames, matchTags

Required no
Type Array[Strings]

Brands are often tagged inconsistently in OpenStreetMap. For example, some mappers write "International House of Pancakes" and others write "IHOP".

This project includes a "fuzzy" matcher that can match alternate names and tags to a single entry in the Name Suggestion Index. The matcher keeps duplicate items out of the index and is used in the iD editor to help suggest tag improvements.

matchNames and matchTags properties can be used to list the less-preferred alternatives.

"properties": {
  "path": "brands/amenity/fast_food"      // all items in this file will match the tag `amenity=fast_food`
  …
},
"items": [
  …
  {
    "displayName": "Honey Baked Ham",
    "id": "honeybakedham-4d2ff4",
    "locationSet": { "include": ["us"] },
    "matchNames": ["honey baked ham company"],    // also match these less-preferred names
    "matchTags": ["shop/butcher", "shop/deli"],   // also match these less-preferred tags
    "tags": {
      "alt_name": "HoneyBaked Ham",                    // match `alt_name`
      "amenity": "fast_food",
      "brand": "Honey Baked Ham",                      // match `brand`
      "brand:wikidata": "Q5893363",
      "cuisine": "american",
      "name": "Honey Baked Ham",                       // match `name`
      "official_name": "The Honey Baked Ham Company"   // match `official_name`
    }
  },
  …

👉 The matcher code also has some useful automatic behaviors…

You don't need to add matchNames for:

  • variations in capitalization, punctuation, spacing (the middots common in Japanese names count as punctuation, so "V・ドラッグ" already matches "vドラッグ")
  • variations that already appear in the name, brand, operator, network.
  • variations that already appear in an alternate name tag (e.g. alt_name, short_name, official_name, etc.)
  • variations that already appear in any international version of those tags (e.g. name:en, official_name:ja, etc.)
  • variations in diacritic marks (e.g. "Häagen-Dazs" already matches "Haagen-Dazs")
  • variations in & vs. and

You don't need to add matchTags for:

  • Tags assigned to match groups (defined in config/matchGroups.json). For example, you don't need add matchTags: ["shop/doityourself"] to every "shop/hardware" and vice versa. Tags in a match group will automatically match any other tags in the same match group.

👉 Bonus: The build script (npm run build) will automatically remove any extra matchNames and matchTags that are unnecessary due to the above automatic features.

note

Required no
Type String

You can optionally add a note property to any item. The note can contain any text useful for maintaining the index - for example, information about the item's real-world status, or a link to a GitHub issue.

The notes just stay within the Name Suggestion Index; they aren't OpenStreetMap tags or used by other software.

{
  "displayName": "United Bank (Connecticut)",
  "id": "unitedbank-28419b",
  "locationSet": { "include": ["peoples_united_bank_ct.geojson"] },
  "note": "Merged into People's United Bank (Q7165802) in 2019, see https://en.wikipedia.org/wiki/United_Financial_Bancorp",
  "tags": {
    …
  }
}

preserveTags

Required no
Type Array[Regex Strings]
Example ["^name"]

For tags matching these regular expressions, values in NSI should not replace an existing value in OSM.

By default, all of the tags as they appear in NSI are how they should appear on an OSM feature. Validator software (such as built into iD) can suggest updates to OSM by comparing an OSM feature's tags against NSI's tags.

In some situations, we want to leave an existing OSM tag value alone. preserveTags contains an Array of regular expressions to match OSM keys where we want to preserve any existing tag value and never suggest a replacement.


👉 The preserveTags property can be set per-category (applying to all items in a category) or per-item.

preserveTags is useful for tags such as "^name" (key starts with "name"), on items where the name tag is expected to be unique:

  • Amazon Locker ("Amazon Locker - Robot")
  • Apple Store ("Apple Bridgewater")

tags

Required yes
Type Object {}

Each item requires a tags value. This is just an Object containing all the OpenStreetMap tags that should be set on the feature in OSM.

Please note that common tags with additional details such as "website" or "contact:facebook" are not accepted by NSI and will be removed from the data by npm run build if submitted. Instead, add a tag referencing the Wikidata entry for the item: "brand:wikidata" for brands; "flag:wikidata" for flags; "operator:wikidata" for operators; and "network:wikidata" for transit networks. The additional details not accepted by NSI (like links to the official websites or Facebook pages of entities) can then be included on the Wikidata entry. If Wikidata does not have an entry for the item, consider adding an entry.

See Editing Wikidata for a list of often-related Wikidata properties.

 

Templates

Templates can appear in the items Array alongside the "normal" items.

A template is placeholder that will expand all the normal items from another source category, but modify the source tags to fit the destination category.

Templates are used in the name-suggestion-index to implement several convenient rules:

  • For each Bank in brands/amenity/bank, create an ATM in brands/amenity/atm but with the operator set to the bank
  • For each Post Office in operators/amenity/post_office, create a Post Box item in operators/amenity/post_box
  • For each Bus Route in transit/route/bus, create a Bus Stop item in transit/highway/bus_stop
  • and more…

See also issue #2883

"properties": {
  "path": "brands/amenity/atm",
  "skipCollection": true,
  "exclude": {"generic": ["^atm$"]}
},
"items": [
  …
  {
    "templateSource": "brands/amenity/bank",
    "templateTags": {
      "amenity": "atm",
      "operator": "{source.tags.brand}",
      "operator:wikidata": "{source.tags.brand:wikidata}"
    }
  },
  …

Template item properties:

templateSource

Required yes
Type String
Example "brands/amenity/bank"

A tree/key/value path to use as the source of the expanded items.

templateTags

Required yes
Type Object {}

By default, all source item tags are copied as-is into the destination item tags.

The templateTags Object contains the tags which should be different (added, modified, or removed).

You can use replacement tokens in the form {source.tags.key} to refer to source tag values. For example, to copy the bank brand tags to ATM operator tags:

{
  "templateSource": "brands/amenity/bank",
  "templateTags": {
    "amenity": "atm",
    "operator": "{source.tags.brand}",
    "operator:wikidata": "{source.tags.brand:wikidata}"
  }
},

You can also use empty tags to indicate that a source tag should not be copied. For example, to expand bus stops for every bus route, you can remove the source route tag like this:

{
  "templateSource": "transit/route/bus",
  "templateTags": {
    "highway": "bus_stop",
    "route": ""
  }
}

templateInclude

Required no
Type Array[Regex Strings]

By default, a template will expand all source items into destination items.

If templateInclude is specified, only the source items with id matching the regular expressions in the templateInclude Array will be included.

See also issue #4866

templateExclude

Required no
Type Array[Regex Strings]

By default, a template will expand all source items into destination items.

If templateExclude is specified, source items with id matching the regular expressions in the templateExclude Array will be excluded.
