  2. Uniform Resource Identifier - Wikipedia

    en.wikipedia.org/wiki/Uniform_Resource_Identifier

    A namespace name does not necessarily imply any of the semantics of URI schemes; for example, a namespace name beginning with http: may have no connotation to the use of the HTTP. Originally, the namespace name could match the syntax of any non-empty URI reference, but the use of relative URI references was deprecated by the W3C. [ 31 ]

  3. Namespace - Wikipedia

    en.wikipedia.org/wiki/Namespace

    For example, the entire C++ Standard Library is defined within namespace std, but before standardization many components were originally in the global namespace. A programmer can insert the using directive to bypass namespace resolution requirements and obtain backwards compatibility with older code that expects all identifiers to be in the ...

  4. info URI scheme - Wikipedia

    en.wikipedia.org/wiki/Info_URI_scheme

    In computing, info is a Uniform Resource Identifier (URI) scheme which enables identifiers from public namespaces to be represented as URIs, when they would otherwise have no canonical URL form, such as Library of Congress identifiers, Handle System handles, and Digital object identifiers.

  5. Uniform Resource Name - Wikipedia

    en.wikipedia.org/wiki/Uniform_resource_name

    A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme.URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable. [1]

  6. List of URI schemes - Wikipedia

    en.wikipedia.org/wiki/List_of_URI_schemes

    A Uniform Resource Identifier helps identify a source without ambiguity. Many URI schemes are registered with the IANA; however, there exist many unofficial URI schemes as well. Mobile deep links are one example of a class of unofficial URI schemes that allow for linking directly to a specific location in a mobile app.

  7. URI fragment - Wikipedia

    en.wikipedia.org/wiki/URI_fragment

    The LiveURLs project [42] proposed a fragment identifier format for referring to a region of text within a page, of the form #FWS+C, where F is the length of the first word (up to five characters), W is the first word itself, S is the length of the selected text and C is a 32-bit CRC of the selected text. [43]

  8. Internationalized Resource Identifier - Wikipedia

    en.wikipedia.org/wiki/Internationalized_resource...

    ASCII code points that are invalid URI characters may be encoded the same way, depending on implementation. [ 6 ] This conversion is easily reversible; by definition, converting an IRI to an URI and back again will yield an IRI that is semantically equivalent to the original IRI, even though it may differ in exact representation.

  9. Scope resolution operator - Wikipedia

    en.wikipedia.org/wiki/Scope_resolution_operator

    In computer programming, scope is an enclosing context where values and expressions are associated. The scope resolution operator helps to identify and specify the context to which an identifier refers, particularly by specifying a namespace or class.
