                   value="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

    Bundle.entry.link corresponds to links found in the HTTP header if the resource in the entry was [read](http://hl7.org/fhir/R5/http.html#read) directly.

    This specification defines some specific uses of Bundle.link for [searching](http://hl7.org/fhir/R5/search.html#conformance) and [paging](http://hl7.org/fhir/R5/http.html#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."/>

However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](http://hl7.org/fhir/R5/references.html#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)."/>
