The @ud-viz/widget_versioning package provides a versioning widget for visualizing and query multiple versioning of a graph within a web application.
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.
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.
The Versioning module requires a SPARQL endpoint that can handle versioned queries defined in the ConVer-G repository.
To configure the SPARQL versioning module extension
For an example of how to the Versioning Widget to a UD-Viz web application see the VersioningWidget example
The Interface is composed of a SPARQL Query window containing a text box for composing queries to send to a Versioning compatible SPARQL Endpoint.
The Results Format dropdown uses the same options as the SPARQL module and also proposes the "versioning" additional option.
You can install the package via npm:
npm install @ud-viz/widget_versioningFeatures:
- Versioning Graph: Display set of versioned graphs fetched from the SPARQL versioned compatible endpoint.
