4. CKG Publishing Model: Triple++
Representing the provenance, time, location, trust score,
probability, etc. of a fact in the form of RDF Triple.
Lightweight syntax
No coordination among publishers
Using existing languages

5. CKG Publishing Model: Triple++
Has a model theory
Reasoning support
Every triple has a global identifier
Enable the tracking of inferred triples
Give credits back to the publishers
