From Web2 data silos
to the semantic Web3

OriginTrail public event

Time: September 8, 17:00 CEST (15:00 UTC/11:00 EST)

I have a dream for the Web in which computers become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A "Semantic Web", which makes this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The "intelligent agents" people have touted for ages will finally materialize.

Tim Berners-Lee

For decades the semantic web vision for the world wide web has remained an aspiration. However, with development of new technologies such as Resource Description Framework (RDF), Web Ontology Language (OWL) and knowledge graphs, putting this vision to life is becoming more viable. In addition to technical developments, we have also seen important advances in companies leveraging network effects (e.g. Facebook, Google, Uber) and new approaches to managing trust in the World Wide Web (using emerging blockchain and blockchain-based networks), both key pieces in ensuring a global realisation of the semantic web.

“From Web2 data silos to the semantic Web3” public event will give us the opportunity to learn from some of the leading figures in these important topics.

We are excited to welcome:

Dr Bob Metcalfe - Professor at University of Texas

The visionary engineer and professor Dr. Metcalfe is often referred to as the father of Ethernet, one of the first computer network systems. Ethernet was created in 1973, long preceding the adoption of personal computers and the spread of business machines. Ethernet today is the most widely installed local network protocol and international computer industry (IEEE) standard. Dr Metcalfe is famous for formulating Metcalfe’s Law, which states that “the value of a network is proportional to the square of the number of connected users.” As the physical cost of the network grows linearly, its value grows exponentially.

Branimir Rakic - CTO at OriginTrail

OriginTrail is a set of tools and protocols built on the OriginTrail Decentralized Knowledge Graph (DKG) designed to bring semantics to Web3. Anyone can build applications for asset discovery, sharing, reasoning and monetization based upon verifiable, structured data and open standards.
