Time and Temporality in Knowledge Graphs

This repository supports ongoing research efforts towards exploring the representation of time and temporality in RDF Knowledge Graphs. It includes all the related materials, e.g. the research outputs - suplemental materials for the research papers, experimental codes and tool prototypes, documentation, visualisations, etc.

• A dedicated submodule contains supplementary material for the journal paper
  "Temporal Modeling in Cultural Heritage Knowledge Graphs: Use Cases, Requirements, Evaluation, and Decision Support".
  The paper forms a central foundation of this dissertation, and several materials are reused and extended here.

• The following repositories contain competency questions (CQs) developed in different cultural heritage initiatives.
  These informed the identification of temporal requirements in this work:

  • Wiedergutmachung CQs
  • TRANSRAZ CQs
  • Linked Stage Graph CQs
  • ArDO CQs
