The document discusses the evolution of the internet from Web 1.0 (static content) to Web 2.0 (user interaction) and finally to Web 3.0, which emphasizes interconnected machine-to-machine communication and the Internet of Things (IoT). It highlights the technologies and protocols integral to each phase, such as RDF, SPARQL, and decentralized systems in Web 3.0. Additionally, it considers security improvements, integration challenges, and the future of technology development within this context.
Web 3.0 & IoT (English)
- 1. Web 3.0 & IoT The future of Internet
- 2. Callenge for 2020 1(2) http://www.ericsson.com/news/110214_more_than_50_billion_244188811_c
- 3. Challenge for 2020 2(2)
- 4. Evolution Web 1.0 Publication Web 2.0 Interaction Automatization Web 3.0 Interoperation IoT Smart City
- 5. Web 1.0 Publication of papers. HTML / HTTP / TCP / IP Links between publications. URI Consumption by humans. Browsers Static information. The publisher provides the information. Centralized.
- 6. Examples of web 1.0 Newspapers Portals Home Pages Britannica Online
- 7. Web 2.0 Dynamic information. Users provide the information. XML, XML Schema, XSLT, XHR (Ajax). New interfaces for humans Apps (10’ interfaces) Web Services. SOAP, WSDL REST, WADL Syndication (RSS, ATOM, Podcasts, etc.)

Internet of Things (IoT) Wireless sensor networks WSN (IPv6 / WiFi) Grid Computing (federation) Security, peer-to-peer (XMPP)
- 13. Abstraction of information Semantic Triples Subject Predicate Object (S, P, O) Can describe all information that exists. S & P are URI’s O can be an URI or a LITERAL Literals can have or lack a type. Every type is defined by an URI.
- 14. Examples of Semantic Triples Clayster “is a” Company Clayster “is domiciled in” Valparaíso Valparaíso “is a” City Valparaíso “lies in” Chile Chile “is a” Country Peter Waher “is a” Man Peter Waher “has” 40 years Peter Waher “is employed by” Clayster. Peter Waher “is married to” Katya Waher. etc.
- 15. URIs URI Format Scheme://Host/Path Simple to extend Simple to maintain unique Simple to distribute

- 20. RDF Example 2(2)
- 21. Ontologies Describe Vocabularies Corresponds to Schemas in the XML-world Permits deduction RDF Schema (RDFS) Very easy Web Ontology Language (OWL) More advanced Three levels (Lite, DL, Full)
- 22. RDFS Example
- 23. Dublin Core Example Describe publicaciones
- 24. Turtle Turtle W3C Recommendation (“Standard”) “Terse RDF Triple Language” Easier to read and write by humans

- 29. OOP for the Semantic Web Objects in OOP are Objects in SW Properties are Predicates Values are Objects. Classes in OOP are also Objects
- 30. Differences between OOP & WS Object Oriented Programming OOP Semantic Web Exclusive Inclusive Centralized Distributed Closed World assumption Open World assumption Proprietary Collaborative Deterministic Indeterministic Classes have heritence Types and properties have heritence
- 31. SPARQL SPARQL W3C Recommendation (“Standard”) “SPARQL Protocol and RDF Query Language” Performs Pattern Matching in semantic graphs. SQL for the Semantic Web. Connection through a “SPARQL Endpoint”. Access to all types of data.

Procedural API’s (~ “web 2.0”) dBase, Paradox, FoxPro, etc. Difficult to join information (relationships) SQL (~ “web 3.0”) MS SQL, Oracle, DB2, MySQL, Sybase, etc. Standardized = Interchangeable Easy to join information from different sources.
- 42. IoT: Web 2.0 vs Web 3.0 ¿How many API’s can be economically supported? ¿10? ¿25? ¿50? ¿100? ¿200? ~2’000’000’000 connected devices ~ 1 / person of middle class 2020: ~50’000’000’000 devices. > 10 / person of middle class ¿How many product providers? ¿How many API’s for integration projects?
- 43. Centralized vs. Distributed Centralized (web 2.0) Distributed (Federation - web 3.0) Expensive Cheap Inefficient Efficient Difficult to grow proportionally Grows organically (~ neural network) Insecure Secure Lack of integrity Maximum of integrity Easy to abuse Difficult to abuse User does not control information User is owner of information
- 44. Plug Computers Linux Server 1,2 Watts 2 USD for 24 / 7 / 365 service. 119 USD/unit price.
- 45. Security in Web 3.0 Based on HTTP Authentication Encryption (SSL/TLS) Decentralized storage Lowers the risk of attacks Lowers the effect of an attack Difficult to attack using an DDOS. Extensions to other protocols XMPP
- 46. XMPP Standardized (IETF) Peer-to-peer Based of XML fragments Data protected by firewalls. Authenticated clients Authorized clients
- 47. Advantages with IETF, W3C, XSF Replaceable components Lowers the cost Permits interchange of information Permits a mixture of providers Power shifts to client Creates a new infrastructure Permits new business models
