Universal Resource Locator Scheme

A Universal Resource Locator (URL) is a type of telecommunications address specified as Internet standard RFC 1738 [http://www.isi.edu/in-notes/rfc1738.txt]. The URL specifies the protocol and the contact point defined by that protocol for the resource.

Properties

Code	URL	Description	Type
Specializes		The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.	Coding
Generalizes		Inverse of Specializes. Only included as a derived relationship.	Coding
internalId	http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id	The internal identifier for the concept in the HL7 Access database repository.	code
status	http://hl7.org/fhir/concept-properties#status	Designation of a concept's state. Normally is not populated unless the state is retired..	code

This code system http://terminology.hl7.org/CodeSystem/v3-URLScheme defines the following codes:

Code	Display	Definition	internalId	status
cid	Content ID	Description: cid: is the most common mechanism used in webservices. A cid: reference points from the SOAP body to other content in the mime package in which the SOAP envelope is wrapped	22603	active
file	File	Host-specific local file names \\[RCF 1738\\]. Note that the file scheme works only for local files. There is little use for exchanging local file names between systems, since the receiving system likely will not be able to access the file.	14872	active

telnet	Telnet	Reference to interactive sessions \\[RFC 1738\\]. Some sites, (e.g., laboratories) have TTY based remote query sessions that can be accessed through telnet.\r\n\r\nhttp://www.ietf.org/rfc/rfc1738.txt	14874	active
fax	Fax	A telephone number served by a fax device \\[http://www.ietf.org/rfc/rfc3966.txt and http://www.ietf.org/rfc/rfc2806.txt\\].	14868	retired

x-text-fax	Fax	Description: A telephone number served by a fax device \\[http://www.ietf.org/rfc/rfc3966.txt and http://www.ietf.org/rfc/rfc2806.txt\\]	22605	retired
x-text-tel	Text Telephone	Description: A text telephone - a telephone which is designed for use by the hearing-impaired\r\n\r\nNotes:\r\n\r\n * x-text-fax is required to replace fax, since this has been deprecated by W3C.\r\n * hl7-att is associated with a series of rules that must be followed. These rules are documented in Datatypes R2\r\n * This domain is external and extensible, so documenting this simply clarifies consistent usage for these use cases.	22606	retired
