Components

The setup is composed of the following:

1. An elasticsearch instance flavoured with following plugins
2. EEA ElasticSearch RDF River Plugin
3. Jetty Plugin
4. FacetView, a pure JavaScript library for browsing data using an elasticsearch endpoint
5. elasticsearch service-wrapper, a script for running elasticsearch using Java Service Wrapper.

This packages specifically includes:

1. Development and production configuration files for elasticsearch and Apache.
2. Custom static pages using facetview js library.
3. PAM, an application using the elasticsearch endpoint.

Live demos

• Facetview visualisation installed on development instance, on EEA Centaurus server.
• Climate change policies and measures in Europe Demo

Development instalation using Vagrant

We provide most of the setup steps in a Vagrant box for a clean install in a virtual machine.

In the same directory clone these projects:

git clone https://github.com/eea/eea.elasticsearch

git clone git clone https://github.com/eea/facetview.git

git clone git@github.com:eea/elasticsearch-servicewrapper.git

Follow instructions in vagrant/README.rst

If you want a local setup follow the instructions in the next section.
