Here is a tabulated "compare and contrast" of Web usage patterns 1.0, 2.0, and 3.0.
| Web 1.0 | Web 2.0 | Web 3.0 | |
| Simple Definition | Interactive / Visual Web | Programmable Web | Linked Data Web |
| Unit of Presence | Web Page | Web Service Endpoint | Data Space (named structured data enclave) |
| Unit of Value Exchange | Page URL | Endpoint URL for API | Resource / Entity / Object URI |
| Data Granularity | Low (HTML) | Medium (XML) | High (RDF) |
| Defining Services | Search | Community (Blogs to Social Networks) | Find |
| Participation Quotient | Low | Medium | High |
| Serendipitous Discovery Quotient | Low | Medium | High |
| Data Referencability Quotient | Low (Documents) | Medium (Documents) | High (Documents and their constituent Data) |
| Subjectivity Quotient | High | Medium (from A-list bloggers to select source and partner lists) | Low (everything is discovered via URIs) |
| Transclusence | Low | Medium (Code driven Mashups) | HIgh (Data driven Meshups) |
| What You See Is What You Prefer (WYSIWYP) | Low | Medium | High (negotiated representation of resource descriptions) |
| Open Data Access (Data Accessibility) | Low | Medium (Silos) | High (no Silos) |
| Identity Issues Handling | Low | Medium (OpenID) | High (FOAF+SSL) |
| Solution Deployment Model | Centralized | Centralized with sprinklings of Federation | Federated with function specific Centralization (e.g. Lookup hubs like LOD Cloud or DBpedia) |
| Data Model Orientation | Logical (Tree based DOM) | Logical (Tree based XML) | Conceptual (Graph based RDF) |
| User Interface Issues | Dynamically generated static interfaces | Dyanically generated interafaces with semi-dynamic interfaces (courtesy of XSLT or XQuery/XPath) | Dynamic Interfaces (pre- and post-generation) courtesy of self-describing nature of RDF |
| Data Querying | Full Text Search | Full Text Search | Full Text Search + Structured Graph Pattern Query Language (SPARQL) |
| What Each Delivers | Democratized Publishing | Democratized Journalism & Commentary (Citizen Journalists & Commentators) | Democratized Analysis (Citizen Data Analysts) |
| Star Wars Edition Analogy | Star Wars (original fight for decentralization via rebellion) | Empire Strikes Back (centralization and data silos make comeback) | Return of the JEDI (FORCE emerges and facilitates decentralization from "Identity" all the way to "Open Data Access" and "Negotiable Descriptive Data Representation") |
Naturally, I am not expecting everyone to agree with me. I am simply making my contribution to what will remain facinating discourse for a long time to come :-)
