Optional Extension Element - found in all resources.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

The purpose of this identifier.

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one. Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

Allows users to make use of identifiers when the identifier system is not known.

This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage.

Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

Establishes the namespace for the value - that is, a URL that describes a set values that are unique.

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

see http://en.wikipedia.org/wiki/Uniform_resource_identifier

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension.

Time period during which identifier is/was valid for use.

This is not a duration - that's a measure of time (a separate type), but a duration that occurs at a fixed value of time. A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). If duration is required, specify the type as Interval|Duration.

Organization that issued/manages the identifier.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

The status property covers the general availability of the resource, not the current value which may be covered by the operationStatus, or by a schedule/slots if they are configured for the location.

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

The Operational status covers operation values most relevant to beds (but can also apply to rooms/units/chair/etc such as an isolation unit/dialisys chair). This typically covers concepts such as contamination, housekeeping and other activities like maintenance.

Codes may be defined very casually in enumerations or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information.

Name of the location as used by humans. Does not need to be unique.

If the name of an location changes, consider putting the old name in the alias column so that it can still be located through searches.

A list of alternate names that the location is known as, or was known as in the past.

Over time locations and organizations go through many changes and can be known by different names.

For searching knowing previous names that the location was known by can be very useful.

There are no dates associated with the alias/historic names, as this is not intended to track when names were used, but to assist in searching so that older names can still result in identifying the location.

Description of the Location, which helps in finding or referencing the place.

Humans need additional information to verify a correct location has been identified.

Note that FHIR strings may not exceed 1MB in size

Indicates whether a resource instance represents a specific location or a class of locations.

When using a Location resource for scheduling or orders, we need to be able to refer to a class of Locations instead of a specific Location.

This is labeled as a modifer because whether or not the location is a class of locations changes how it can be used and understood.

Indicates the type of function performed at the location.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

The contact details of communication devices available at the location. This can include phone numbers, fax numbers, mobile numbers, email addresses and web sites.

Physical location.

If locations can be visited, we need to keep track of their address.

This was kept as 0..1 as there is no use property on the address, so wouldn't be able to identify different address types.

Physical form of the location, e.g. building, room, vehicle, road.

For purposes of showing relevant locations in queries, we need to categorize locations.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

Longitude. The value domain and the interpretation are the same as for the text of the longitude element in KML (see notes below).

Do not use a IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

Latitude. The value domain and the interpretation are the same as for the text of the latitude element in KML (see notes below).

Do not use a IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

Altitude. The value domain and the interpretation are the same as for the text of the altitude element in KML (see notes below).

Do not use a IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

The organization responsible for the provisioning and upkeep of the location.

Need to know who manages the location.

This can also be used as the part of the organization hierarchy where this location provides services. These services can be defined through the HealthcareService resource.

Another Location which this Location is physically part of.

For purposes of location, display and identification, knowing which locations are located within other locations is important.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

Technical endpoints providing access to services operated for the location.

Organizations may have different systems at different locations that provide various services and need to be able to define the technical connection details for how to connect to them, and for what purpose.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
