Open Events Database

Welcome to the code repository of the Open Event Search Engine (OESE) and Open Events Database project.

We have a fancy project homepage here: http://events.input23.de

Install

If you want to run the Events Database, you only need to install docker and docker-compose.

If you are on a newer Ubuntu Version follow the instructions of: https://gist.github.com/wdullaer/f1af16bd7e970389bad3

###Run the Elasticsearch instance and import event data

  1. Start ElasticSearch, Kibana:

    [sudo] docker-compose up -d
  2. Setup the elasticsearch index:

    (You only need to do this once before the first run of the event importers)

    cd elasticserch;./create_index.sh
  3. Run the importers to import data into your elasticsearch instance: Check out the directory scripts and run the import engines of your desired regions or event types.

    E.g. for the Münster events this would be:

    cd scripts
    cd scrapers-muenster
    ./install.sh
    perl muenster-scraper.pl

###Run the JSON REST API In order to start it, you just need to docker-compose up and then start the Strongloop Loopback API Server. Check out the details in our detailed readme for strongloop.

Then you can check out the following urls:

Example elasticsearch queries

# geo location query for events
curl -XGET localhost:9200/events/event/_search?pretty=true -d '
{
         "query" : {
             "match_all" : {}
         },
         "filter" : {
             "geo_distance" : {
                 "distance" : "10km",
                 "event.location.geo" : {
                     "lat" : "51.96066",
                     "lon" : "7.62613"
                 }
             }
         }
}
'
