Resource Profile: ItemTransactionRequest - Detailed Descriptions

Draft as of 2023-07-08

Definitions for the ItemTransactionRequest resource profile.

Guidance on how to interpret the contents of this table can be found here.

1. Bundle
2. Bundle.type
Definition

This transaction Bundle is to convey the request to create/update/delete/patch content of a catalog, from the Catalog Owner to the Catalog Custodian

Indicates the purpose of this bundle - how it is intended to be used.

Comments

This transaction Bundle is usable with any kind of catalog (laboratory compendium, drug formulary, order sets, devices ...)

It's possible to use a bundle for other purposes (e.g. a document can be accepted as a transaction). This is primarily defined so that there can be specific rules for some of the bundle types.

Fixed Valuetransaction
3. Bundle.entry
Definition

Each entry will contain a resource representing a catalog item or one of the supporting resources of a catalog item. The resource will be followed by a request instructing the Catalog Custodian what action (create/update/delete/patch) to perform on this resource

An entry in a bundle resource - will either contain a resource or information about a resource (transactions and history only).

Primitive ValueThis primitive element may be present, or absent, or replaced by an extension

Comments

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.

6. Bundle.entry.fullUrl
Definition

The Absolute URL for the resource. Except for transactions and batches, each entry in a Bundle must have a fullUrl. The fullUrl SHALL NOT disagree with the id in the resource - i.e. if the fullUrl is not a urn:uuid, the URL shall be version-independent URL consistent with the Resource.id. The fullUrl is a version independent reference to the resource. Even when not required, fullUrl MAY be set to a urn:uuid to allow referencing entries in a transaction. The fullUrl can be an arbitrary URI and is not limited to urn:uuid, urn:oid, http, and https. The fullUrl element SHALL have a value except when:

  • invoking a create
  • invoking or responding to an operation where the body is not a single identified resource
  • invoking or returning the results of a search or history operation.

Comments

fullUrl might not be unique in the context of a resource. Note that since FHIR resources do not need to be served through the FHIR API, the fullURL might be a URN or an absolute URL that does not end with the logical id of the resource (Resource.id). However, but if the fullUrl does look like a RESTful server URL (e.g. meets the regex, then the 'id' portion of the fullUrl SHALL end with the Resource.id.

Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL).

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

Typeinstant
Primitive ValueThis primitive element may be present, or absent, or replaced by an extension
Summarytrue
Comments

For many bundles, the timestamp is equal to .meta.lastUpdated, because they are not stored (e.g. search results). When a bundle is placed in a persistent store, .meta.lastUpdated will be usually be changed by the server. When the bundle is a message, a middleware agent altering the message (even if not stored) SHOULD update .meta.lastUpdated. .timestamp is used to track the original time of the Bundle, and SHOULD be populated.

Usage:

  • document : the date the document was created. Note: the composition may predate the document, or be associated with multiple documents. The date of the composition - the authoring time - may be earlier than the document assembly time
  • message : the date that the content of the message was assembled. This date is not changed by middleware engines unless they add additional data that changes the meaning of the time of the message
  • history : the date that the history was assembled. This time would be used as the _since time to ask for subsequent updates
  • searchset : the time that the search set was assembled. Note that different pages MAY have different timestamps but need not. Having different timestamps does not imply that subsequent pages will represent or include changes made since the initial query
  • transaction | transaction-response | batch | batch-response | collection : no particular assigned meaning

The timestamp value should be greater than the lastUpdated and other timestamps in the resources in the bundle, and it should be equal or earlier than the .meta.lastUpdated on the Bundle itself.

Comments

Both Bundle.link and Bundle.entry.link are defined to support providing additional context when Bundles are used (e.g. HATEOAS).

Bundle.entry.link corresponds to links found in the HTTP header if the resource in the entry was read directly.

This specification defines some specific uses of Bundle.link for searching and paging, but no specific uses for Bundle.entry.link, and no defined function in a transaction - the meaning is implementation specific. The behavior of navigation link types (next/prev/first/last) are well defined for searchset and history Bundles but are not currently defined for other types. Implementers who choose to use such link relationships for other bundle types will need to negotiate behavior with their interoperability partners.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

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.

21. Bundle.entry.fullUrl
Definition

The Absolute URL for the resource. Except for transactions and batches, each entry in a Bundle must have a fullUrl. The fullUrl SHALL NOT disagree with the id in the resource - i.e. if the fullUrl is not a urn:uuid, the URL shall be version-independent URL consistent with the Resource.id. The fullUrl is a version independent reference to the resource. Even when not required, fullUrl MAY be set to a urn:uuid to allow referencing entries in a transaction. The fullUrl can be an arbitrary URI and is not limited to urn:uuid, urn:oid, http, and https. The fullUrl element SHALL have a value except when:

  • invoking a create
  • invoking or responding to an operation where the body is not a single identified resource
  • invoking or returning the results of a search or history operation.

Comments

fullUrl might not be unique in the context of a resource. Note that since FHIR resources do not need to be served through the FHIR API, the fullURL might be a URN or an absolute URL that does not end with the logical id of the resource (Resource.id). However, but if the fullUrl does look like a RESTful server URL (e.g. meets the regex, then the 'id' portion of the fullUrl SHALL end with the Resource.id.

Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL).

Requirements

A Signature holds an electronic representation of a signature and its supporting context in a FHIR accessible form. The signature may either be a cryptographic type (XML DigSig or a JWS), which is able to provide non-repudiation proof, or it may be a graphical image that represents a signature or a signature process. This element allows capturing signatures on documents, messages, transactions or even search responses, to support content-authentication, non-repudiation or other business cases. This is primarily relevant where the bundle may travel through multiple hops or via other mechanisms where HTTPS non-repudiation is insufficient.

Comments

The signature could be created by the "author" of the bundle or by the originating device. Requirements around inclusion of a signature, verification of signatures and treatment of signed/non-signed bundles is implementation-environment specific.

Usage notes: These issues and warnings must apply to the Bundle as a whole, not to individual entries.Messages relating to the processing of individual entries (e.g. in a batch or transaction) SHALL be reported in the entry.response.outcome for that entry. If there are errors that arise in the creation of the Bundle, then that should be handled by an OperationOutcome being returned instead of the Bundle.
