For applications and protocols that do not allow direct consumption of IRIs, the IRI should first be converted to Unicode using canonical composition normalization (NFC), if not already in Unicode format. All non-ASCII code points in the IRI should next be encoded as UTF-8, and the resulting bytes percent-encoded, to produce a valid URI.
Microsoft .NET (for example, the method new Uri(path)) generally uses the 2-slash form; Java (for example, the method new URI(path)) generally uses the 4-slash form. Either form allows the most common operations on URIs (resolving relative URIs, and dereferencing to obtain a connection to the remote file) to be used successfully.
This implies that the base URI exists and is an absolute URI (a URI with no fragment component). The base URI can be obtained, in order of precedence, from: [13]: §5.1 the reference URI itself if it is a URI; the content of the representation; the entity encapsulating the representation; the URI used for the actual retrieval of the representation;
A component is undefined if it has an associated delimiter and the delimiter does not appear in the URI; the scheme and path components are always defined. [ 13 ] : §5.2.1 A component is empty if it has no characters; the scheme component is always non-empty.
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.
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.

A URI Template is a way to specify a URI that includes parameters that must be substituted before the URI is resolved. It was standardized by RFC 6570 in March 2012. The syntax is usually to enclose the parameter in Braces ({example}). The convention is for a parameter to not be Percent encoded unless it follows a Question Mark (?).
Clients are not supposed to send URI fragments to servers when they retrieve a document. [1] [2] A URI ending with # is permitted by the generic syntax and is a kind of empty fragment. In MIME document types such as text/html or any XML type, empty identifiers to match this syntactically legal construct are not permitted. Web browsers typically ...
