John Aizen & Eran Shir (Dapper) - Practical Semantic Web (web plumbing 101)
Posted by rmp at 00:08 5th Oct 2007
TBL once said "in the future everyone will write semantically correct websites" but the vision of a world of personalised agents has not come about. Largely things failed to take off because making things semantically correct is expensive - it requires effort.
Luckily current web apps are changing this with APIs, content distribution & aggregation and meaningful search.
How has this come about?
- The Feed
- Light, easily adopted technologies: e.g. REST vs. SOAP; AJAX vs. Server-side; Microformats vs. RDF+OWL
- Increasing openness, encouraging mashups via APis and low-effort semantics
Introducing Dapper: Creating APIs for other websites, mostly community-generated. The users have the time and incentive. Dapper extensions can then be reused as services on top of other platforms, e.g. Pipes, Google gadgets & Facebook.
Example: Semantically linked advertising, e.g. a loaded shopping cart built on a recipe page.
Example: Meaningful search w/ results dissected enabling search, drill-down and filtering by automatically indexed categories
Dapper attempts to address the serious issues of fragility commonly associated with classical screen-scraping using elements of graph theory and community power.
Dapper also incorporates the gamut of CC licensing to better enable site-owners to control their content whilst boosting consumer confidence in reliability of data.
