Ontology engineering

The first step to creating a personal knowledge graph is to build an ontology for a project or process. This requires the following steps:

• start seeing objects and background/context and catalogue them in your model;
• start seeing relations between objects and classify those relations as static (structural) or dynamic (causal, functional, behavioural or dependency);
• structure those objects and relations into domains with boundaries, causality ladder, and taxonomies.

Let's consider each step separately.
