#URI
Cool Uris For The Semantic Web
Web document (information resource)
Like everything on the traditional Web, each of the pages mentioned above are Web documents. Every Web document has its own URI. Note that a Web document is not the same as a file: a single Web document can be available in many different formats and languages, and a single…
Cool URIs: be on the Web, be unambiguous
Given such a URI, how can we find out what it identifies? We need some way to answer this question, because otherwise it will be hard to achieve interoperability between independent information systems. We could imagine a service where we can look up a description of the…
URIs for things that are not web pages
Web documents have always been addressed with URIs (in common parlance often referred as Uniform Resource Locators, URLs). This is useful because it means we can easily make RDF statements about Web pages, but also dangerous because we can easily mix up Web pages and the…
Hash URIs versus 303 redirects
The solutions described in the following apply to deployment scenarios in which the RDF data and the HTML data is served separately, such as a standalone RDF/XML document along with an HTML document. The metadata can also be embedded in HTML, using technologies such as RDFa…
Dereferenceable Uniform Resource Identifier - Wikipedia, The Free Encyclopedia
Dereferenceable URIs are based on the well-established theory and practices of "data access by reference"
Because of the nature of a URI, it can be dereferenced to get the information of the thing it represents—hence the term dereferenceable URI. SSN and a person's name are not dereferenceable because, even though you could search for these strings on the Web, it is not guaranteed…
Internationalized Resource Identifiers (iris)
The philosophical problem of identifiers
There is a philosophical problem with all identifiers, particularly obvious in an international context. Identifiers are not only used by computers, but also by humans. Humans have a strong preference for using mnemonic names: you call the address field in a form address and…
Linked Data: Evolving The Web Into A Global Data Space
Any HTTP URI should be dereferenceable
Any HTTP URI should be dereferenceable, meaning that HTTP clients can look up the URI using the HTTP protocol and retrieve a description of the resource that is identified by the URI. This applies to URIs that are used to identify classic HTML documents, as well as URIs that…
Making Uris Dereferenceable | Ontogenealogy
How URIs identifying information and non-information resources are dereferenced
URI Dereferencing is the process of looking up a URI on the Web in order to get information about the referenced resource. The W3C’s Dereferencing HTTP URIs distinguished between how URIs identifying information and non-information resources are dereferenced: Information…
The Web is intended to be an information space that may be used by humans as well as by machines
HTTP URIs should be dereferenceable, i. e. HTTP clients can look up the URI using the HTTP protocol and retrieve a description of the resource that is identified by the URI. The Web is intended to be an information space that may be used by humans as well as by machines. Both…
Rdf Primer
RDF identifies with URIrefs, browsers retrieve
Both RDF and Web browsers use URIrefs to identify things. However, RDF and browsers interpret URIrefs in slightly different ways. This is because RDF uses URIrefs only to identify things, while browsers also use URIrefs to retrieve things. Often there is no effective…
Setting a base URI with XML Base
...relative URIrefs such as #item10245 will be interpreted relative to a base URI. By default, this base URI would be the URI of the resource in which the relative URIref is used. However, in some cases it is desirable to be able to explicitly specify this base URI. For…
Naming statements happens outside RDF
RDF does not provide a built-in way of indicating how a URIref like exproducts:triple12345 is associated with a particular statement or graph, any more than it provides a built-in way of indicating how a URIref like exproducts:item10245 is associated with an actual tent…
Blank nodes for things without URIs
Blank nodes also provide a way to more accurately make statements about resources that may not have URIs, but that are described in terms of relationships with other resources that do have URIs. [..] The point is that saying something like "the author of the book is…
Xml qualified name (or qname)
For convenience, the Primer uses a shorthand way of writing triples (the same shorthand is also used in other RDF specifications). This shorthand substitutes an XML qualified name (or QName) without angle brackets as an abbreviation for a full URI reference (QNames are…
RDF: metadata about things on the Web
The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. It is particularly intended for representing metadata about Web resources, such as the title, author, and modification date of a Web page, copyright and…
Thesauri Of Historical Periods – A Proposal For Standardization.
Naming periods like biological species
[...] we identify a period concept with the term plus a reference to the first known publication that actually defined it, just as it is good practice in biology (Berendsohn 1995). We propose to create unique preferred terms as in biology (e.g.: Fringilla coelebs Linnaeus…
What Do Http Uris Identify? - Design Issues
Uris for web pages vs uris for real world objects
HTTP URIs, in the web architecture, have been used to denote documents -- "web pages" informally, or "information resources" more formally. However, with the growth of the Semantic Web, which uses URIs to denote anything at all, the urge to use and practice of using HTTP URIs…
