LDVMi

Looking for LinkedPipes Visualization Assistant?

This project is developed as a replacement for visualization parts in Payola project. Its goal is to provide better reliability, scalability and resolve some issues which cannot be easily resolved Payola due to its architecture.

Based on LDVM principles, it enables a user to visualize data in their dataset while it automatically offers list of suitable visualizers.

• User Guide

Right now, it provides those visualization techniques:

• DataCube
• OpenLayers WKT multipolygon
• Treemap
• GoogleMaps

Implemented analyzers:

• RUIAN geocoder
• SPARQL Query
• UNION
• RUIAN Geocoder [CZ]

It also provides a simple JSON API in order to allow creating datasources and visualizations automatically by 3rd party software.

Running the app

• download Typesafe Activator at https://www.typesafe.com/get-started
• clone the project
• in the src folder execute activator run (you need to have activator in your PATH)
• if you don't have any SPARQL endpoint running at http://localhost:8890/sparql, you may need to change the configuration in order to have everything running smoothly (e.g. pipeline execution, creating a datasource from TTL, ...)
