Configuration

The following options are supported:

• endpointUrl: URL to the SPARQL endpoint which will be used in the YASGUI interface. If a path is given instead of a URL, it will be resolved using the absolute URL (default value: /query)
• urlShortener: URL of an URL Shortener service. It will be called like this (assuming urlShortener is https://example.com/api/v1/shorten): https://example.com/api/v1/shorten?url=url-to-your-query and should return a short URL as plain text (https://example.com/s/x8Z1a). If urlShortener is not defined, the short URL feature will be disabled in YASGUI.
• template: Path to an alternative template (default: views/yasgui.hbs)
• catalog: Array of SPARQL endpoints that will be shown in the YASGUI interface.
• defaultQuery: Default query that will be shown in the YASGUI interface.
• mapKind: Map kind to use in the YASGUI interface (default: default ; supported values: default, swisstopo)
