Europeana SPARQL console

This repository contains the source code for the Europeana SPARQL console.

Attribution to Wikidata Query Service GUI

This service was developed on top of the Wikibase Query Service GUI, see Github repository and is distributed under EUPLv1.2 (compatible with Apache License 2.0 of the original work).

It includes the following changes to the orginal source code:

• Changed SPARQL endpoint to use a configurable Europeana SPARQL endpoint instead of Wikidata SPARQL
• Changed Wikidata ontology by the Europeana Data Model
• Changed examples to reflect the change in ontology
• Changed menus to point to different resources
• Added feedback button

Manual

We are developing a user manual of our version but in the meantime, you can discover some of the functionality of the service in Wikidata's User Manual.

Download & setup

Clone git repo, go into created folder and then pull all dependencies via npm package manager.

$ git clone https://gerrit.wikimedia.org/r/wikidata/query/gui
$ cd gui
$ npm install

Alternatively, use npm install.

npm install wikidata-query-gui

Configuration

Per default the Wikibase Query Service GUI is configured to be used as a local development test instance. It can be customized by creating a custom-config.json in the repository's root dir. This file can be used to override any of the default settings obtained from default-config.json.

Banner Message

The banner message may be configured per site deployment. In order display a banner, add its banner key to the configuration:

{
// ...
  "bannerName": "query-builder",
// ...
}

Empty values, falsy values and undefined banner keys will result in the banner not showing.

Run tests

Run JSHint, JSCS and QUnit tests.

$ npm test

Debug

Start a test server for local debugging. Do not use it in production.

$ npm start

Build

Create a build with bundled and minified files.

$ npm run build

Deploy

To deploy the GUI, trigger a new build of the deploy repo on Jenkins.

This creates a new open change in the deploy repository: https://gerrit.wikimedia.org/r/q/project:wikidata/query/gui-deploy+status:open That change will be based on the latest commit in the master branch, and thus it will include all previous commits. Optionally, you can edit the commit message in the Gerrit UI to include the Bug: Txxxxx line, to emphasize to which task the change belongs.

You can clone that repository and check out the change locally to test and verify it.

As that repository does not have any CI, you need to manually merge the change. That means, giving +2 to both the Code Review as well as the Verified label, and then clicking the "Submit" button.

The site will be deployed with the next puppet run, which should happen after at most 30 minutes.

Components

Editor

A CodeMirror based SPARQL editor with code completion (ctrl+space) and tooltips (hover).

var editor = new wikibase.queryService.ui.editor.Editor();
editor.fromTextArea( $( '.editor' )[0] );

See examples/editor.html.

Example dialog

A dialog that allows browsing of SPARQL examples.

new wikibase.queryService.ui.dialog.QueryExampleDialog(  $element, querySamplesApi, callback, previewUrl );

See examples/dialog.html.

SPARQL

var api = new wikibase.queryService.api.Sparql();
api.query( query ).done( function() {
	var json = JSON.parse( api.getResultAsJson() );

} );

See examples/sparql.html. JSFiddle.net

Result Views

Views that allow rendering SPARQL results (see documentation).

var api = new wikibase.queryService.api.Sparql();
api.query( query ).done(function() {
	var result = new wikibase.queryService.ui.resultBrowser.CoordinateResultBrowser();
	result.setResult( api.getResultRawData() );
	result.draw( element );
} );

See examples/result.html. JSFiddle.net

Release Notes and npm package

Unfortunately there are no releases and the provided code and interfaces are not considered to be stable. Also the dist/ folder contains a build that may not reflect the current code on master branch.
