Graph versioning demo

Explore how evolving quad datasets are generated, compressed, queried, and visualized across versions.

Visualize versioned quads with QuaViz

  • Navigate through quads versions with the metagraph.
  • Understand the diffs between two versioned graph.

QuaDer: import and condense quads datasets

It stores:

  • All resources or literals in a catalog.
  • Evolving quad datasets in a compressed form using bit vectors to represent the presence of quads across versions.

Quads Query - cross versions · Quads Query - cross versions with inference

Query condensed versioned quads with QuaQue

  • It supports SPARQL queries without introducing new operators, maintaining interoperability.
  • QuaQue allows querying across multiple versions simultaneously using the condensed quad representation.
  • The component uses the condensed representation to improve the execution of join and aggregation queries.

Interactive widget

Versioning explorer

The table below is injected dynamically. This panel is intentionally wide and scrollable so large version histories remain usable.
