Three amazingly intelligent and eloquent people help me understand rather a lot of concepts. What is a commonsense Knowledge Graph? Using Schema.org structured data to manage your data layer. Ontologies are containers full of entities that have relationships (use triples !!!). Lots of philosophy around computer science - specifically ontologies. Entity management is the future (thanks, Greg Gifford). We are all becoming data architects. Three levels of knowledge. Databases expressing opinions. How semantics help sell t-shirt bras. Manage your brand for machines (not just search !). And rather a lot more... Amazing.
