@ud-viz/widget_versioning
The @ud-viz/widget_versioning package provides a versioning widget for visualizing and query multiple versioning of a graph within a web application.
Versioning Module
The Versioning Module is an extension of the SPARQL Module that adds functionality to query and visualize multiple versions of graphs stored in an RDF Triple-store from a UD-Viz interface.
See the SPARQL module for more documentation on generic SPARQL functions.
Versioning functionalities
This module extends the functionality of the SPARQL module with the ability to detext the similarities between various urban knowledge graphs. These nodes are displayed in a D3 graph created from Versioning graph data from a SPARQL backend service.
Data requirements
The Versioning module requires a SPARQL endpoint that can handle versioned queries defined in the ConVer-G repository.
Setup
To configure the SPARQL versioning module extension
Usage
For an example of how to the Versioning Widget to a UD-Viz web application see the VersioningWidget example
User Interface
