With linked data, when you have some of it, you can find other, related, data.
-
Use URIs as names for things
-
Use HTTP URIs so that people can look up those names.
-
When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL)
-
Include links to other URIs. so that they can discover more things.
-
It is the unexpected re-use of information which is the value added by the web.
-
these involve not wanting to commit to the established Domain Name System (DNS) for delegation of authority but to construct something under separate control
-
Many research and evaluation projects in the few years of the Semantic Web technologies produced ontologies, and significant data stores, but the data, if available at all, is buried in a zip archive somewhere, rather than being accessible on the web as linked data
-
In hypertext web sites it is considered generally rather bad etiquette not to link to related external material.

a surprising amount of data isn't linked in 2006, because of problems with one or more of the steps. This article discusses solutions to these problems, details of implementation, and factors affecting choices about how you publish your data
-
It is the unexpected re-use of information which is the value added by the web.
-
the data, if available at all, is buried in a zip archive somewhere, rather than being accessible on the web as linked data
-
The value of your own information is very much a function of what it links to, as well as the inherent value of the information within the web page. So it is also in the Semantic Web
-
Whenever one looks up the URI for a node in the RDF graph, the server returns information about the arcs out of that node, and the arcs in. In other words, it returns any RDF statements in which the term appears as either subject or object

s your Linked Open Data 5 Star?
(Added 2010). This year, in order to encourage people -- especially government data owners -- along the road to good linked data, I have developped this star rating system.Linked Data is defined above. Linked Open Data (LOD) is Linked Data which is released under an open licence, which does not impede its reuse for free. Creative Commons CC-BY is an example open licence, as is the UK's Open Government Licence. Linked Data does not of course in general have to be open -- there is a lot of important use of lnked data internally, and for personal and group-wide data. You can have 5-star Linked Data without it being open. However, if it claims to be Linked Open Data then it does have to be open, to get any star at all.
Under the star scheme, you get one (big!) star if the information has been made public at all, even if it is a photo of a scan of a fax of a table -- if it has an open licence. The you get more stars as you make it progressively more powerful, easier for people to use.★ Available on the web (whatever format) but with an open licence, to be Open Data ★★ Available as machine-readable structured data (e.g. excel instead of image scan of a table) ★★★ as (2) plus non-proprietary format (e.g. CSV instead of excel) ★★★★ All the above plus, Use open standards from W3C (RDF and SPARQL) to identify things, so that people can point at your stuff ★★★★★ All the above, plus: Link your data to other people’s data to provide context

Linked data is essential to actually connect the semantic web. It is quite easy to do with a little thought, and becomes second nature. Various common sense considerations determine when to make a link and when not to.

Ben GodfreyTimBL's notes on architecting linked open data sets.
-
06 Apr 10

The first rule, to identify things with URIs, is pretty much understood by most people doing semantic web technology. If it doesn't use the universal URI set of symbols, we don't call it Semantic Web.
-
The second rule, to use HTTP URIs, is also widely understood. The only deviation has been, since the web started, a constant tendency for people to invent new URI schemes (and sub-schemes within the urn: scheme) such as LSIDs and handles and XRIs and DOIs and so on, for various reasons. Typically, these involve not wanting to commit to the established Domain Name System (DNS) for delegation of authority but to construct something under separate control. Sometimes it has to do with not understanding that HTTP URIs are names (not addresses) and that HTTP name lookup is a complex, powerful and evolving set of standards. This issue discussed at length elsewhere, and time does not allow us to delve into it here. [ @@ref TAG finding, etc])
-
There is also a large and increasing amount of URIs of non-ontology data which can be looked up. Semantic wikis are one example. The "Friend of a friend" (FOAF) and Description of a Project (DOAP) ontologies are used to build social networks across the web. Typical social network portals do not provide links to other sites, nor expose their data in a standard form.
-
LiveJournal and Opera Community are two portal web sites which do in fact publish their data in RDF on the web.
