SPARQL Executor README

The SPARQL Executor Visual Studio Code extension is a simple utility which allows you to configure SPARQL end-points and execute SPARQL queries.

Features

Configure Multiple SPARQL Endpoints

Open settings.json in Visual Studio Code and add SPARQL endpoints:

For example: the following configuration defines a Wikidata and a Dbpedia endpoint:

"sparql-executor.endpoints": [
       {
         "protocol": "https",
         "host": "query.wikidata.org",
         "path": "/sparql",
         "name": "Wikidata",
         "customHeaders": [
           {
             "headerName": "User-Agent",
             "headerValue": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0"
           },
         ],
         "method": "GET",
         "queryParameterName": "query"
       },
       {
         "protocol": "https",
         "host": "dbpedia.org",
         "name": "DBpedia",
         "path": "/sparql"
       }
]

Select From SPARQL Endpoints

Select SPARQL Endpoint Using Command Palette

• cmd + shift + P
• Type the command Select SPARQL Endpoint
• Hit enter
• Search for and highlight your desired endpoint
• Hit enter

Select SPARQL Endpoint Using Key Command

The default key command for selecting a SPARQL endpoint is: control + shift + E.

Execute SPARQL Queries

Execute SPARQL Query Using Command Palette

• cmd + shift + P
• Type the command Execute SPARQL Query
• Hit enter

Execute SPARQL Query Using Key Command

The default key command for executing a SPARQL query is: control + shift + X.

Extension Settings

This extension contributes the following settings:

• sparql-executor.endpoints: configured list of SPARQL endpoints
• sparql-executor.endpoints.protocol: SPARQL endpoint protocol (https or http)
• sparql-executor.endpoints.host: SPARQL endpoint host, e.g. example.com (do not include a path)
• sparql-executor.endpoints.path: SPARQL endpoint path, e.g. /sparql
• sparql-executor.endpoints.method: SPARQL endpoint HTTP method, e.g. GET (defaults to POST)
• sparql-executor.endpoints.queryParameterName: Custom SPARQL query post data/query string parameter name, e.g. query
• sparql-executor.endpoints.output: SPARQL results output formar, e.g. table (defaults to json)
• sparql-executor.endpoints.customHeaders: Define custom headers to be included in the SPARQL request
• sparql-executor.endpoints.customHeaders.[].headerName: Name of the custom header
• sparql-executor.endpoints.customHeaders.[].headerValue: Value of the custom header
• sparql-executor.endpoints.authentication: SPARQL endpoint authentication configuration
• sparql-executor.endpoints.authentication.type: SPARQL endpoint authentication type (currently only supports basic)
• sparql-executor.endpoints.authentication.username: SPARQL endpoint authentication username (for basic auth)
• sparql-executor.endpoints.authentication.password: SPARQL endpoint authentication password (for basic auth)
