Data-Pesticides

Data-Pesticides is a web application based on Silex PHP microframework that provides a full-featured data-visualization about pesticides concentrations in France. The web application is available online : https://www.data-pesticides.fr. It has been created in response to a contest launched by the French ministry of ecology, energy and the sea.

Application requirements :

• A web server (such as Nginx or Apache)
• PHP 5.6+
• composer
• A RDF Triplestore (for instance, you can use Blazegraph)

### Installation :

All the data required by the application are already bundled within the package datasets/source.tar.gz.

• Install the latest version of Blazegraph, launch it through the command java -server -Xmx4g -jar blazegraph.jar, and create a new namespace named 'datapesticides' (with the mode option set to 'quads'). That's all for the database part.
• Make sure the directories var/cache/ and datasets/ are writeable
• Configure a new host into your favorite web server. See here for more information about setting up a Silex application into your web server.
• Set your own application parameters into the configuration file app/config/config.php. Basically, you will need to update the host value with your own local host you have set in your webserver for running the application.
• run the command install.sh in order to launch composer install, datasets imports and API warm up. It can take a while depending on your computer performance
• Then, go to the application homepage and enjoy !

Import new dataset

In order to import new datasets into the triplestore, you just have to run the command bin/console data-pesticides:load-dataset with the following argument depending on which kind of dataset you want to load :

• --type=stations=xxx : pesticides|roles|departments|station_statements|station_statements_total, the type of dataset you want to import
• --file=/path/to/dataset.csv : The path to the dataset you want to import
• --year=xxxx : The year related to the dataset (only for station_statements and station_statements_total types)

You can also launch the command without any parameter in order to enter into the interactive mode. You an take a look at the ìnstall.sh script in order to see some examples of commands.

Warmup the API Cache

In order to refresh all the data served by the API, you can run the following command :

bin/console data-pesticides:warmup-api

If you only want to refresh a particular API method, you can call it through your browser and add ?refresh at the end of the URL, for instance www.yourlocaldomain.com/api/data/getStations?refresh.
