Referenced Content Item Identifier Attribute

Tag(0040,DB73)
TypeConditionally Required (1C)
KeywordReferencedContentItemIdentifier
Value Multiplicity1-n
Value RepresentationUnsigned Long (UL)

An ordered set of one or more integers that uniquely identifies the Target Content Item of the relationship.

The root Content Item is referenced by a single value of 1.

Each subsequent integer represents an ordinal position of a Content Item in the Content Sequence (0040,A730) in which it belongs. The Referenced Content Item Identifier is the set of these ordinal positions along the by-value relationship path. The number of values in this Multi-Value Attribute is exactly the number of relationships traversed in the Content Tree plus one.

Note

  1. See Section C.17.3.2.5.

  2. Content Items are ordered in a Content Sequence starting from 1 as defined in VR of SQ (see PS3.5).

Required if the Target Content Item is denoted by-reference, i.e., the Document Relationship Macro and Document Content Macro are not included.

Section C.17.3.2.5

C.17.3.2.5 Referenced Content Item Identifier

Content Items are identified by their position in the Content Item tree. They have an implicit order as defined by the order of the Sequence Items. When a Content Item is the target of a by-reference relationship, its position is specified in the Referenced Content Item Identifier (0040,DB73) in a Content Sequence Item subsidiary to the source Content Item.

Note

Figure C.17.3-3 illustrates an Content Tree and identifiers associated with each Content Item:

Table C.17-6. Document Relationship Macro Attributes

Attribute Name

Tag

Type

Attribute Description

Observation DateTime

(0040,A032)

1C

The date and time on which this Content Item was completed. For the purpose of recording measurements or logging events, completion time is defined as the ending time of data acquisition of the measurement, or the ending time of occurrence of the event.

Required if the date and time are different from Content Date (0008,0023) and Content Time (0008,0033) or Observation DateTime (0040,A032) defined in higher Items. May be present otherwise.

Note

When Content Items are copied into successor reports, Content Date (0008,0023) and Content Time (0008,0033) of the new report are likely to be different than the date and time of the original observation. Therefore this Attribute may need to be included in any copied Content Items to satisfy the condition.

Observation UID

(0040,A171)

3

Unique identifier for the observation Content Item (and its subsidiary Content Items, if any). The UID represents the semantic content of the observation; an encoding of the same observation with the same context into another representation (e.g., a CDA Entry) may use the same UID.

Content Sequence

(0040,A730)

1C

A potentially recursively nested Sequence of Items that conveys content that is the Target of Relationships with the enclosing Source Content Item.

One or more Items shall be included in this Sequence.

Required if the enclosing Content Item has relationships.

Note

  1. If this Attribute is not present then the enclosing Item is a leaf.

  2. The order of Items within this Sequence is semantically significant for presentation.

See Section C.17.3.2.4 for further explanation.

>Relationship Type

(0040,A010)

1

The type of relationship between the (enclosing) Source Content Item and the Target Content Item.

IODs specify additional constraints on Relationships (including lists of Enumerated Values).

Enumerated Values:

CONTAINS

HAS PROPERTIES

HAS OBS CONTEXT

HAS ACQ CONTEXT

INFERRED FROM

SELECTED FROM

HAS CONCEPT MOD

See Section C.17.3.2.4 for further explanation.

>Include Table C.17-6 “Document Relationship Macro Attributes” if the Target Content Item is included by-value in the Source Content Item. The Macro shall not be present if the relationship is by-reference.

>Include Table C.17-5 “Document Content Macro Attributes” if the Target Content Item is included by-value in the Source Content Item. The Macro shall not be present if the relationship is by-reference.

>Referenced Content Item Identifier

(0040,DB73)

1C

An ordered set of one or more integers that uniquely identifies the Target Content Item of the relationship.

The root Content Item is referenced by a single value of 1.

Each subsequent integer represents an ordinal position of a Content Item in the Content Sequence (0040,A730) in which it belongs. The Referenced Content Item Identifier is the set of these ordinal positions along the by-value relationship path. The number of values in this Multi-Value Attribute is exactly the number of relationships traversed in the Content Tree plus one.

Note

  1. See Section C.17.3.2.5.

  2. Content Items are ordered in a Content Sequence starting from 1 as defined in VR of SQ (see PS3.5).

Required if the Target Content Item is denoted by-reference, i.e., the Document Relationship Macro and Document Content Macro are not included.

Concept Name Code Sequence

(0040,A043)

1C

Code describing the concept represented by this Content Item. Also conveys the value of Document Title and section headings in documents.

Only a single Item shall be included in this Sequence.

Required if Value Type (0040,A040) is TEXT, NUM, CODE, DATETIME, DATE, TIME, UIDREF, TABLE or PNAME.

Required if Value Type (0040,A040) is CONTAINER and a heading is present, or this is the Root Content Item.

Note

That is, containers without headings do not require Concept Name Code Sequence

Required if Value Type (0040,A040) is COMPOSITE, IMAGE, WAVEFORM, SCOORD, SCOORD3D or TCOORD, and the Purpose of Reference is conveyed in the Concept Name.

Note

Though many Templates in PS3.16 do not require that the Purpose of Reference be conveyed in the Concept Name, a generic Concept Name, such as (260753009, SCT, "Source"), may be used, since anonymous (unnamed) Content Items may be undesirable for some implementations (e.g., for which the name of a name-value pair is required). UMLS (C0449416) maps (260753009, SCT, "Source") to (C25683, NCIt, "Source"). NCIt defines it as "Where something is available or from where it originates".

See Section C.17.3.2.2 for further explanation.

>Include Table 8.8-1 “Code Sequence Macro Attributes”

No Baseline CID is defined.

Text Value

The text value may contain spaces, as well as multiple lines separated by CR LF, but otherwise no format control characters (such as horizontal or vertical tab and form feed) shall be present, even if permitted by the Value Representation of UT.

The text shall be interpreted as specified by Specific Character Set (0008,0005) if present in the SOP Common Module.

Note

The text may contain single or multi-byte characters and use code extension techniques as described in PS3.5 if permitted by the values of Specific Character Set (0008,0005).
