This page describes the WDQS interface and helps you to understand the various possibilities to display results on SPARQL query service.

The query example page contains many good examples you can try!

Open the WDQS interface and then:

• select your language in of the upper tool bar.
• write a valid SPARQL code in the text area.
• check your script by hovering the elements with your mouse; tooltips appear and should be consistent with what you intend to do. They adopt the language you have selected (default to english).
• then click on blue button Execute query of the sidebar to launch the request. Red square is lit in the sidebar while the command executes.
• after running a query, you can choose in the "Display" formats which result view you want to display. Depending on your query and the data type, some of the views will not be available.

Note: You can also run directly a hardcoded request via the TryIt links of this page. When it brings you directly to the result display you can always return to the source script unsing the link at the bottom of the interface.

表（默認）

Shows the result data as a table. It is the default view for results and can display every data type.

Will map every variable from the SPARQL select clause to a formatted table column.

• 
  Table Result
• 
  Table Result on small screens with flipped columns

Image Grid

Image Grid Try Out

Shows the result data as a grid with images.

Every grid item has a big picture and opens the gallery when clicking on it.

Contents an item is the formatted row data.

Variable	Data Type	Mapping	Description
*	Commons Media	Grid Item	Image columns will create a grid item.

Rows containing no image will be ignored.

It’s nonetheless possible to include no image rows in the result by modifying the sparql by including a default image in case the image variable is not bound:

  optional {
    ?item wdt:P18 ?img_ .
  }
  bind (if(bound(?img_), 
           ?img_, 
           <http://commons.wikimedia.org/wiki/Special:FilePath/File:Profile_avatar_placeholder_large.png>) as ?image) # [[:commons:File:Profile_avatar_placeholder_large.png]] as a placeholder

Here the file commons:File:Profile avatar placeholder large.png is used as a placeholder, you can use your own.

See a complete query example using this technique.

Options

Option name	Type	Description
hide	One or more variable names (strings, starting with ?), single value or array	Don’t show these variables in the result.

Map

Shows the result data as map with OpenStreetMap data.

Variable	Data Type	Mapping	Description
*	Coordinate or Geographic shape	Map Marker	Columns will create a marker on the map. Content of that marker is the formatted row data.
?layer		Map Marker Layer	Creates a colored map layer that allows filtering.
?rgb	Color	Color Map Marker	Example 000000 for black color.

• File:Map with layers
• 
• File:Map of airports in Belgium

Technically, any well-known text literal can be displayed, not just a point coordinate.

Non-point geometry values are never stored on Wikidata, but they can be constructed in SPARQL using functions like CONCAT() and STRDT() – see this map of Czech railway lines for an example of LINESTRING() geometry.

Options

specify using e.g. #defaultView:Map{"hide":["?foo", "?bar"],"layer":"?bar"}, using an array when there are multiple variables.

Option name	Type	Description
hide	One or more variable names (strings, starting with ?), single value or array	Don’t show these variables in the result.
layer	One or more variable names (strings, starting with ?), single value or array	Use these variables for the map layer, instead of the default ?layerLabel, ?layer.
markercluster	boolean or object	If the value is an object, pass these options to Leaflet.markercluster, a map plugin for clustering nearby map markers. (If the value is the empty object {}, Leaflet.markercluster is enabled with its default options.) If the value is true (default for queries without map layers), Leaflet.markercluster is enabled with a special set of options that doesn’t cluster any nearby map markers (it only “spiderfies” markers with exactly identical coordinates) and attempts to replicate the default map look as much as possible. If the value is false (default for queries with map layers), Leaflet.markercluster is not enabled.

折線圖，棒形圖，散點圖同埋面積圖

Shows one of these chart types.

Variable	Data Type	Mapping	Description

Mobile / Responsive

Result views are made to work on different devices and resolutions. Their appearance may change depending on the space they can use.

Embed Mode

Result views can be linked or embedded via iframes. You can get the regarding link or code by clicking Link in the above menu.

See the difference: link to a query and link to a result or the embed code:

<iframe style="width:80vw; height:50vh;" scrolling="yes" frameborder="0" src="http://tinyurl.com/zwf4k2w">

Download results

Download results buttons

There are several ways to export the results of a query.

JSON, TSV and CSV are three different open-standard formats to download the data, offered under the Download tab. To get results in XML format, click on Link > SPARQL endpoint.

You can also download some of the graphic views as a SVG file: this feature works with all the views except table, image grid, timeline, graph builder, map, and graph.

Default View

The default view can be change for each SPARQL query by using a comment:

#defaultView:[NAME]

For example:

#defaultView:ImageGrid

Result view options

Result views can be configured with various options, which are specified in JSON (Q2063) format, either following the defaultView comment (see previous section) or following a separate view comment.

#defaultView:Map{"layer": "?typeLabel"}
#view:ImageGrid{"hide": "?coords"}

Title

Result views can show a title. The title can be set via a title comment.

#title:A title of your choice

Auto language

When using the magic keyword [AUTO_LANGUAGE] it is replaced by the users language when submitting the query. This allows writing a query with where the result is displayed in the users language.

Example:

#<span lang="en" dir="ltr" class="mw-content-ltr">Use language of the user for display labels and fallback to english as default</span>
SERVICE wikibase:label {
    bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
}

Auto coordinates

When using the magic keyword [AUTO_COORDINATES] it is replaced by the users location when submitting the query (with clients accepting the geolocalization). This allows writing a query with the users' location.

Example:

#defaultView:Map
SELECT ?place ?coordinate_location ?dist {
SERVICE wikibase:around {
    ?place wdt:P625 ?coordinate_location.
    bd:serviceParam wikibase:center "[AUTO_COORDINATES]".
    bd:serviceParam wikibase:radius "1".
    bd:serviceParam wikibase:distance ?dist.
  }
}
