Web Project

In /src, a generic web-project with bower and npm is set up.

Installation

NodeJS and NPM are needed to install the rest, so first install

• nodejs https://nodejs.org/en/download/
• npm https://docs.npmjs.com/cli/install

Then, install node packages for gulp and bower with something like npm install --global gulp bower (it might be necessary to run this as superuser).

Then, change into poject folder and start npm and bower to fetch dependencies:

$ cd src
$ npm install
$ bower install

This will install the project dependencies, after which you should be able to start the developmend server with

$ gulp serve

Elasticsearch Server

Elasticsearch binaries are available at the Elasticsearch website: https://www.elastic.co/products/elasticsearch

Find the executables in elasticsearch-2.1.0/bin .

Elasticsearch Server - Windows

exectue the file elasticsearch-2.1.0\bin\elasticsearch.bat

Import documents

1. delete any old index (if you want to reload)

   curl -XDELETE 'localhost:9200/opendata?pretty'

2. create the index

   curl -XPUT 'localhost:9200/opendata?pretty'

3. create and load the mapping file

   curl -XPUT localhost:9200/opendata/statement/_mapping?pretty -d @data/mapping.json

4. load the json dataset

   curl -XPOST localhost:9200/opendata/statement/_bulk?pretty --data-binary @data/export-minimal.json
