All codes in this table are from the system http://terminology.hl7.org/CodeSystem/v3-URLScheme

cidContent 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
fileFileHost-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.
ftpFTPThe File Transfer Protocol (FTP) \[RFC 1738\].
hl7-attHL7 Attachment**Description:** A reference to an HL7 attachment by it's identifier, which takes the form hl7-att:\[II.literal\], such as hl7-att:
httpHTTPHypertext Transfer Protocol \[RFC 2068\]. http://www.ietf.org/rfc/rfc2068.txt
mailtoMailtoElectronic mail address \[RFC 2368\] http://www.ietf.org/rfc/rfc2368.txt
mllpMLLP**Description:** Mimimal Lower Layer Protocol. See Transport Specification: MLLP, Release 2 (HL7 V3 Transport specification).
nfsNFSNetwork File System protocol \[RFC 2224\]. Some sites use NFS servers to share data files. http://www.ietf.org/rfc/rfc2224.txt
telTelephoneA voice telephone number \[http://www.ietf.org/rfc/rfc3966.txt and http://www.ietf.org/rfc/rfc2806.txt\].
telnetTelnetReference to interactive sessions \[RFC 1738\]. Some sites, (e.g., laboratories) have TTY based remote query sessions that can be accessed through telnet. http://www.ietf.org/rfc/rfc1738.txt
faxFaxA telephone number served by a fax device \[http://www.ietf.org/rfc/rfc3966.txt and http://www.ietf.org/rfc/rfc2806.txt\].
modemModemA telephone number served by a modem device \[http://www.ietf.org/rfc/rfc3966.txt and http://www.ietf.org/rfc/rfc2806.txt\].
x-text-faxFax**Description:** A telephone number served by a fax device \[http://www.ietf.org/rfc/rfc3966.txt and http://www.ietf.org/rfc/rfc2806.txt\]
x-text-telText Telephone**Description:** A text telephone - a telephone which is designed for use by the hearing-impaired **Notes:** * x-text-fax is required to replace fax, since this has been deprecated by W3C. * hl7-att is associated with a series of rules that must be followed. These rules are documented in Datatypes R2 * This domain is external and extensible, so documenting this simply clarifies consistent usage for these use cases.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
