Unlimited amount of information (unbounded)
Limited amount of information (bounded)
The complete information space is known, categorized and indexed
Only parts of the information space are known, categorized and indexed
A single unified system of concepts securing unambiguous categorization of recourses as well as semantic interoperability across resources (“complete understanding”)
Several partially competing systems of concept producing alternative categorization of resources as well as low levels of semantic interoperability across resources (“partial understanding”)
Centralized: a single publisher and registration authority
Decentralized: millions of publishers – no central authority
Broken links (the famous 404)
Unlimited scalabilityLocal versus global information systems
“The design of the Web fundamentally differed from traditional hypertext systems in sacrificing link integrity for scalability.”
Tim Berners-Lee: “Web Architecture: Describing and Exchanging Data”,
The Semantic WebTowards the Semantic Web
“Human endeavor is caught in an eternal tension between the effectiveness of small groups acting independently and the need to mesh with the wider community.
A small group can innovate rapidly and efficiently, but this produces a subculture whose concepts are not understood by others. Coordinating actions across a large group, however, is painfully slow and takes an enormous amount of communication.
The world works across the spectrum between these extremes, with a tendency to start small—from the personal idea—and move toward a wider understanding over time.”
Tim Berners-Lee, James Hendler and Ora Lassila
The Semantic Web,
Scientific American, May 2001
“The Semantic Web is an extension of the current Web in which information is given well defined meaning, better enabling computers and people to work in cooperation.”
To develop a truly distributed platform for electronic publishing of statistical data, building on object technology, open (metadata-) standards and lightweight Internet protocols.
To bring the models, technologies and collective energy of the Web to the world of statistics.
The ability to locate multiple data sources across national boundaries
The ability to browse detailed information about these data sources
..and to do data analysis and visualisation over the net
..or to download the appropriate subset of data in one of a number of formats
Supporting standard micro-data as well as aggregated tables/cubes
Allowing the user to bookmark/hyperlink resources in the data and metadata repositories
analysis (tables, models etc.)
..and to hyperlink these resources from external Web-objects (like texts)
Support for metadata indexing using a multilingual thesaurus
Powerful data preparation tools, including a system for remote publishing of data to NESSTAR serversNesstar – an overview
