The Library resource is a general-purpose container for knowledge asset definitions. It can be used to describe and expose existing knowledge assets such as logic libraries and information model descriptions, as well as to describe a collection of knowledge assets.

An absolute URI that is used to identify this library when it is referenced in a specification, model, design or an instance. instance; also called its canonical identifier. This SHALL be a URL, SHOULD be globally unique, unique and SHOULD be an a literal address at which at which an authoritative instance of this library is (or will be) published. The This URL SHOULD include can be the major version target of a canonical reference. It SHALL remain the library. For more information see Technical and Business Versions . same when the library is stored on different servers.

Allows the library to be referenced by a single globally unique identifier.

Can be a urn:uuid: or a urn:oid:, urn:oid: but real http: addresses are preferred. Multiple instances may share the same url URL if they have a distinct version.

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions .

A formal identifier that is used to identify this library when it is represented in other formats, or referenced in a specification, model, design or an instance. e.g. CMS or NQF identifiers for a measure artifact. Note that at least one identifier is required for non-experimental active artifacts.

Allows externally provided and/or usable business identifiers to be easily associated with the module.

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, e.g., to and can then identify this library outside of FHIR, where it is not possible to use the logical URI.

The identifier that is used to identify this version of the library when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the library author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active artifacts.

There may be different library instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a refrence reference to a particular business version of the library with the format [url]|[version].

A natural language name identifying the library. This name should be usable as an identifier for the module by machine processing applications such as code generation.

Support human navigation and code generation.

The name is not expected to be globally unique. The name should be a simple alpha-numeric alphanumeric type name to ensure that it is computable machine-processing friendly.

A short, descriptive, user-friendly title for the library.

This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc.

An explanatory or alternate title for the library giving additional information about its content.

The status of this library. Enables tracking the life-cycle of the content.

Allows filtering of librarys libraries that are appropriate for use vs. not. This is labeled as "Is Modifier" because applications should not use a retired library without due consideration.

A boolean Boolean value to indicate that this library is authored for testing purposes (or education/evaluation/marketing), education/evaluation/marketing) and is not intended to be used for genuine usage.

Enables experimental content to be developed following the same lifecycle that would be used for a production-level library.

Allows filtering of library librarys that are appropriate for use vs. versus not. This is labeled as "Is Modifier" because applications should not use an experimental library in production.

Identifies the type of library such as a Logic Library, Model Definition, Asset Collection, or Module Definition.

A code or group definition that describes the intended subject of the contents of the library.

The date (and optionally time) when the library was published. The date must change if and when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the library changes.

Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the library. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

The name of the individual or organization or individual that published the library.

Helps establish the "authority/credibility" "authority/credibility" of the library. May also allow for contact.

Usually an organization, organization but may be an individual. The publisher (or steward) of the library is the organization or individual primarily responsible for the maintenance and upkeep of the library. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the library. This item SHOULD be populated unless the information is available from context.

Contact details to assist a user in finding and communicating with the publisher.

May be a web site, an email address, a telephone number, etc.

A free text natural language description of the library from a consumer's perspective.

This description can be used to capture details such as why the library was built, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the library as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the profile library is presumed to be the predominant language in the place the profile library was created).

The content was developed with a focus and intent of supporting the contexts that are listed. These terms may be used to assist with indexing and searching for appropriate library instances.

Assist in searching for appropriate content.

When multiple useContexts are specified, there is no expectation that all or any of the contexts apply.

A legal or geographic region in which the library is intended to be used.

It may be possible for the library to be used in jurisdictions other than those for which it was originally designed or intended.

Explaination Explanation of why this library is needed and why it has been designed as it has.

This element does not describe the usage of the library Instead library. Instead, it provides traceability of ''why'' the resource is either needed or ''why'' it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this library.

A detailed description of how the library is used from a clinical perspective.

A copyright statement relating to the library and/or its contents. Copyright statements are generally legal restrictions on the use and publishing of the library.

Consumers must be able to determine any legal restrictions on the use of the library and/or its content.

The date on which the resource content was approved by the publisher. Approval happens once when the content is officially approved for usage.

The 'date' element may be more recent than the approval date because of minor changes / or editorial corrections.

The date on which the resource content was last reviewed. Review happens periodically after approval, approval but doesn't does not change the original approval date.

Gives a sense of how "current" "current" the content is. Resources that have not been reviewed in a long time may have a risk of being less appropriate/relevant.

If specified, this is usually after date follows the original approval date.

The period during which the library content was or is planned to be in active use.

Allows establishing a transition before a resource comes into effect and also allows for a sunsetting process when new versions of a the library are or are expected to be used instead.

The effective period for a library determines when the content is applicable for usage and is independent of publication and review dates. For example, a measure intended to be used for the year 2016 might be published in 2015.

Descriptive topics related to the content of the library. Topics provide a high-level categorization of the library that can be useful for filtering and searching.

Repositories must be able to determine how to categorize the library so that it can be found by topical searches.

Related artifacts such as additional documentation, justification, or bibliographic references.

Libraries must be able to provide enough information for consumers of the content (and/or interventions or results produced by the content) to be able to determine and understand the justification for and evidence in support of the content.

Each related artifact is either an attachment, or a reference to another resource, but not both.

The parameter element defines parameters used by the library.

Describes a set of data that must be provided in order to be able to successfully perform the computations defined by the library.

The content of the library as an Attachment. The content may be a reference to a url, or may be directly embedded as a base-64 string. Either way, the contentType of the attachment determines how to interpret the content.
