Introduction

This tool helps dataprovider to define SmartQueries. Those query will be used by users to perform search and view result on a map.

To illustrate how to use this tool, let's take an example and define a SmartQuery for the landslides use case :

In order to define a SmartQuery, you need to create a Template, which basically contains all the information to perform a SparqlRequest.

After you have created that template, you can define an Instance of it and then execute the search query to see the result on a map.

All those steps will be explain in more details in the parts below.

Add a new Template
