Styles

specdraftimplcandidate

Publish styles.

Scope

Clients can discover, access, use, and update styles in the following stylesheet encodings:

Mapbox/MapLibre Style
OGC SLD 1.0
OGC SLD 1.1
QGIS QML
ArcGIS Desktop (lyr)
ArcGIS Pro (lyrx)
3D Tiles Styling

Styles available as Mapbox/MapLibre Style can be used by ldproxy to render features and vector tiles where MapLibre is used as the map client. Styles available as 3D Tiles Styling can be used by ldproxy to render features and vector tiles where Cesium is used as the map client. See defaultStyle in HTML, and style in Features HTML and Tiles.

Limitations

All encodings of a style must be created and maintained separately. The on-the-fly derivation of a stylesheet in another stylesheet encoding is not supported.

The following limitations apply for the stylesheet encodings:

Mapbox/MapLibre Style: The stylesheets are parsed into an internal Java object. Not all structures are
supported or validated:
- Only a single sprite is supported.
- Terrain is not supported.
- Text strings (e.g., color values) are not validated.
- filter, layout and paint values are not validated.
- Interpolate expressions are only supported in layout and paint values.
- Sources: volatile is not supported.
- Vector sources: promoteId is not supported.
3D Tiles Styling: The stylesheets are parsed into an internal Java object. Text strings in
the JSON are not validated. The defines key is not supported.
OGC SLD 1.0/1.1: The content of these stylesheets is validated against the XML Schema.
QGIS QML, ArcGIS Pro (lyrx), ArcGIS Desktop (lyr): The content of these stylesheets is not validated.

Conformance Classes

This building block implements requirements of the conformance classes Core, Manage Styles, Validation of styles, Resources, Manage resources, Mapbox Style, OGC SLD 1.0, OGC SLD 1.1, HTML and Style information from the draft specification OGC API - Stylesopen in new window. The implementation is subject to change in the course of the development and approval process of the draft.

Operations

Resource	Path	Methods	Media Types	Description
Styles	`styles`	GET	HTML, JSON	This operation fetches the list of styles. For each style the id, a title, links to the stylesheet of the style in each supported encoding, and the link to the metadata is provided.
Style	`styles/{styleId}`	GET	3D Tiles Declarative Styling, ArcGIS, ArcGIS Pro, HTML, Mapbox, QGIS, SLD 1.0, SLD 1.1	This operation fetches the list of styles. For each style the id, a title, links to the stylesheet of the style in each supported encoding, and the link to the metadata is provided.
Style Metadata	`styles/{styleId}/metadata`	GET	HTML, JSON	Style metadata is essential information about a style in order to support users to discover and select styles for rendering their data and for visual style editors to create user interfaces for editing a style. This operation returns the metadata for the requested style as a single document. The style metadata is derived from the style and the stylesheet.
Style Legend	`styles/{styleId}/legend`	GET	PNG	This endpoint retrieves the legend for a map style. The legend is provided as a PNG file, which can be used to understand the symbols and colors used in the map style.
Collection Styles	`collections/{collectionId}/styles`	GET	HTML, JSON	This operation fetches the list of styles. For each style the id, a title, links to the stylesheet of the style in each supported encoding, and the link to the metadata is provided.
Collection Style	`collections/{collectionId}/styles/{styleId}`	GET	3D Tiles Declarative Styling, ArcGIS, ArcGIS Pro, HTML, Mapbox, QGIS, SLD 1.0, SLD 1.1	Fetches the style with identifier `styleId`. The set of available styles can be retrieved at `/styles`. Not all styles are available in all style encodings.
Collection Style Metadata	`collections/{collectionId}/styles/{styleId}/metadata"`	GET	HTML, JSON	Style metadata is essential information about a style in order to support users to discover and select styles for rendering their data and for visual style editors to create user interfaces for editing a style. This operations returns the metadata for the requested style as a single document. The stylesheet of the style will typically include some the metadata, too.
Collection Style Legend	`collections/{collectionId}/styles/{styleId}/legend`	GET	PNG	This endpoint retrieves the legend for a map style. The legend is provided as a PNG file, which can be used to understand the symbols and colors used in the map style.
Styles, Style	`styles, styles/{styleId}`	DELETE, POST, PUT	3D Tiles Declarative Styling, ArcGIS, ArcGIS Pro, HTML, Mapbox, QGIS, SLD 1.0, SLD 1.1	Create, Replace and Delete styles.
Collection Styles, Collection Style	`collection/{collectionId}/styles, collection/{collectionId}/styles/{styleId}`	DELETE, POST, PUT	3D Tiles Declarative Styling, ArcGIS, ArcGIS Pro, HTML, Mapbox, QGIS, SLD 1.0, SLD 1.1	Create, Replace and Delete styles of a feature collection.

Path Parameters

Name	Resources	Description
`collectionId`	Collection Styles, Collection Style, Collection Style Metadata, Collection Style Legend	The identifier of the feature collection.
`styleId`	Style, Style Metadata, Style Legend, Collection Style, Collection Style Metadata, Collection Style Legend	The local identifier of the style.

Query Parameters

Name	Resources	Description
`f`	Styles	Select the output format of the response. If no value is provided, the standard HTTP rules apply, i.e., the "Accept" header will be used to determine the format.
`f`	Style	Select the output format of the response. If no value is provided, the standard HTTP rules apply, i.e., the "Accept" header will be used to determine the format.
`dry-run`	Styles, Collection Styles	If set to 'true', the operation just validates the content without creating a new style.
`dry-run`	Style, Collection Style	If set to 'true', the operation just validates the content without creating a new style or updating an existing style.

Configuration

Storage

MapLibre stylesheets reside in the Store as values with type
maplibre-styles and path {apiId}/{styleId}. In the latter case the extension mbs is
still supported, but preferably stylesheets are stored as plain YAML or JSON files. The URIs (Sprites,
Glyphs, Source.url, Source.tiles) used in MapLibre styles links might contain {serviceUrl}.
3d Tiles stylesheets reside in the Store as values with type
3dtiles-styles and path {apiId}/{styleId}. In the latter case the extension 3dtiles
is still supported, but preferably stylesheets are stored as plain YAML or JSON files.
Other stylesheets reside in the Store as resources with type
other-styles and path {apiId}/{styleId}.{ext}.
The file extension {ext} must have the following value depending on the style encoding:
- OGC SLD 1.0: sld10
- OGC SLD 1.1: sld11
- QGIS QML: qml
- ArcGIS Desktop: lyr
- ArcGIS Pro: lyrx

Layer Control

The layer control dialog in the webmap is activated via the webmapWithLayerControl option (see 'Options' below).

The dialog can be configured in the MapLibre style metadata (member ldproxy:layerControl). On the top level there are the following JSON members:

onlyLegend (Boolean, default: false): With true only the groups and layers with the symbols are displayed without the possibility to deactivate layers.
opened (Boolean, default: false): If true is set, the layer selection dialog will be displayed open when the map is loaded.
entries (default: one merge group per source layer in the vector tiles): The configuration of the groups and layers as described below.

In entries the following items allowed:

The id of a MapLibre layer in the style (string). The layer is displayed in the dialog with the id as name. The symbol of the layer is created without specifying attributes or a particular zoom layer.
A layer object. id is the id of the MapLibre layer in the style (string, mandatory). label is the name of the layer in the dialog (string, default: id). zoom is the zoom level to use when creating symbols (number, default: none). properties are attributes (object, default {}) to be used during symbol generation.
A group object. type is always "group". id is an id of the group (string, mandatory). label is the name of the group in the dialog (string, default: id). With onlyLegend the possibility to disable layers can be disabled for the group (Boolean, default: false). entries can contain layers (objects or string), groups or merge groups (array, default: []).
A radio group object. It may only occur on the top level of entries. Only exactly one entry can be selected from the group, e.g. for the selection of a basemap. type is always "radio-group". id, label have the same effect as for normal groups. entries can only contain layers (objects or string) (array, default: []).
A merge group object. type is always "merge-group". A merge group is a group where entries may only contain layers (objects or string) (array, default: []); these entries are not displayed as subentries in the dialog, but a symbol is created from all layers together. Instead of specifying entries, source-layer (string, default: none) can be specified alternatively; in this case, all layers with this source layer become entries.

For an example, see below.

Options

Name	Default	Description	Type	Since
`buildingBlock`		Always `STYLES`.	string	v3.1
`enabled`	`false`	Enable the building block?	boolean	v3.1
`caching`	`{}`	Sets fixed values for HTTP Caching Headers for the resources.	object	v3.1
`styleEncodings`	`[ "Mapbox", "HTML" ]`	List of enabled stylesheet encodings. Supported are Mapbox/MapLibre Style (`Mapbox`), OGC SLD 1.0 (`SLD10`), OGC SLD 1.1 (`SLD11`), QGIS QML ("QML"), ArcGIS Layer ("lyr" und "lyrx"), 3D Tiles ("3D Tiles") and HTML (`HTML`). HTML is an output only encoding for web maps that requires a Mapbox/MapLibre Style stylesheet. For details see conformance classes Mapbox Style, OGC SLD 1.0, OGC SLD 1.1 und HTML. Upcoming change Currently there is no way to disable the defaults `Mapbox` and `HTML`. That will be changed in v4, you will then have to repeat the defaults if you want to add additional encodings.	array	v3.1

`useIdFromStylesheet`			boolean	v3.1
`deriveCollectionStyles`	`false`	Only applies to styles in Mapbox Style format. Controls whether the styles at the collection level should be derived from the styles in the parent style collection. The prerequisite is that the name of the `source` in the stylesheet corresponds to `{apiId}` and the name of the `source-layer` corresponds to `{collectionId}`. If a style is to be used for displaying features in the FEATURES_HTML building block, the option should be enabled.	boolean	v3.1
