Tim Berners-Lee Says the Time for the Semantic Web is Now
In an hour long interview posted today about the Semantic Web, W3C Director Tim Berners-Lee says all the pieces are in place to move full steam ahead and realize the potential of a world of structured, machine readable data.
Context & Ripple Effects
ReadWriteWeb has been building toward this interview for months. Its September 2007 piece on the difficulties with the classic approach argued the W3C's top-down ontology route was stalling, and its October follow-up on the new era of semantic apps tracked startups layering semantics onto existing data instead. By January the open question was which killer app would carry the stack.
What changes today is who is answering: Berners-Lee himself — the man who wrote the first Web client in 1990 — declares in an hour-long interview that the infrastructure for structured, machine-readable data is finally in place. That is a standards-blessed green light aimed directly at the app builders ReadWriteWeb has been profiling.
First-order effects
- Developers and startups in the semantic-app wave get direct endorsement from the Web's inventor, which de-risks betting on RDF-style structured data over scraping-and-heuristics approaches.
- ReadWriteWeb's own framing question — what is the killer app? — becomes more urgent rather than settled, since Berners-Lee's 'pieces in place' claim shifts attention from whether to build to what to build first.
Second-order effects
- Toolmakers and framework authors around W3C standards gain a recruiting argument against ad-hoc data formats, pressuring application developers to expose machine-readable endpoints alongside human-facing pages.
- Search and aggregation products face rising expectations that sites publish structured data, since the inventor's imprimatur makes 'we'll clean it up later' a harder pitch to investors and partners.
Third-order effects
- If adoption follows, the Web's core unit shifts from the linked document to the linked dataset — a re-architecture of publishing that puts whoever structures data first at an advantage in discovery and reuse.
- The pattern also reinforces Berners-Lee's long-running role as the Web's normative voice: his readiness calls have historically marked phase changes, from hypertext in 1990 through his advocacy for smarter browsing tools announced around the Web's fifteenth anniversary in 2005.
The trend: The Web is transitioning from a web of documents for people into a web of structured, machine-readable data, with the W3C's founder setting the pace of adoption.
