Try the Linked Data Fragments jQuery Widget online.
This jQuery widget is a browser-based user interface to the Linked Data Fragments client. It allows users to execute SPARQL queries over one or multiple datasets exposed through a Triple Pattern Fragments interface.
- Run
npm install
to fetch dependencies and build the browser version of the client code. - Place the files from this repository on a local Web server (for instance, by starting a tool such as https://github.com/ddfreyne/adsf in the root folder).
- Open
index.html
in the browser through your Web server (typicallyhttp://localhost:3000/
). - Edit datasources in
settings.json
and queries in thequeries
folder, and runqueries-to-json
to compile both of them in a single JSON file. - Run
./build-minified
to generate a production version in thebuild
folder.
The original ldf-client library is written for the Node.js environment. The browserify library makes it compatible with browsers.
The file browser.js
makes the Node.js library ldf-client available in global scope as ldf
.
This script is compiled with its dependencies to deps/ldf-client-browser.js
via npm run postinstall
.
You can use the resulting ldf-client-browser.js
in your browser applications; it is independent of the jQuery UI widget.
If you want to rapidly deploy this widget as a microservice, you can build a Docker container as follows:
$ docker build -t ldf-client-widget .
Next, configure your widget by creating a settings.json
file in your working directory based on the example.
Next, create a queries
directory in which you should insert the queries that will be present by default in the widget, as is done here.
After that, you can run your newly created container in which settings.json
and queries
is mounted to the Docker container:
$ docker run -p 8080:8080 -it --rm -v $(pwd)/settings.json:/tmp/settings.json -v $(pwd)/queries:/tmp/queries ldf-client-widget
