Deltas, Diffs and Event Modeling

Semantic Web Interest Group,
AI Knowledge Representation Community Group,

Is there interest here in deltas and diffs to semantic graphs and to sets of predicate calculus expressions? Is there interest here in how these deltas and diffs pertain to modeling events?

I am considering deltas and diffs, additions and removals of statements or expressions and modifications to statements or expressions. I am considering whether such deltas and diffs could be first-class elements in some object models and how they might pertain to event modeling.

We can consider a knowledgebase which contains knowledge about a perceived world or environment. Such deltas and diffs represent changes to knowledgebase contents which seems to be a topic proximate to modeling events. We could add timestamps to deltas and diffs and consider streams of such deltas or diffs. I am thinking about the relationships between knowledgebase deltas and diffs and modeling events.

Any thoughts on deltas, diffs and event modeling? Any projects or publications which you could recommend?
