Questions on SR IOD

1. Section C.6.8 Findings Module on page 44.

   Table C.6.8-1 specifies the Attributes that shall convey the Findings Group Context. Finding Group Context
   has four dimensions: 1) Observer Context, 2) Procedure Context, 3) Observation Subject Context, and 4)
   Observation Category (optional). Each ...
   ...
   Any number of Observations, identified by Observation UID (0040,A171) and Observation Class (0040,A170),
   may constitute the Findings of each Findings Group. The Observations Module, Section C.6.13 of this Part,
   specifes the mechanism for expressing Observations and describing Relationships between Observations.
   

   Table C.6.8-1 FINDINGS MODULE ATTRIBUTES contains the following Attributes:

   Findings Sequence                  (0040,A020)  1
   >Procedure Context Flag            (0040,A603)  1C
   >Findings Group UID                (0040,A021)  1C
   >Findings Group Recording Date     (0040,0023)  3
   >Findings Group Recording Time     (0040,0024)  3
   

   My Comments

   I can not see any dimensions in this Table. It gives only the Findings Group UID. It does not say anything about Observer Context, Procedure Context, Observation Subject Context and Observation Category. How will you make a connection between these things?

2. Section C.6.9 Observation Category Module on page 46.

   Table C.6.9-1 specifies the Attributes that convey the Observations.
   
         Table C.6.9-1 -- Observation Category Module Attributes
   
   Attribute Name           Tag          Type    Attribute Description
   Observation Category   (0040,A167)      1     The historical category of 
   Code Sequence                                 this Findings Group. Exactly one item
   
   >Include 'Code Sequence Macro' Table 8.8-1    Baseline Context ID is 52.
   

   My Comments

   Which Findings Group? Let us suppose there are three Findings Group.

   Findings Sequence                  (0040,A020) 
   First item ----------------------------------------------
   >Procedure Context Flag            (0040,A603)
   >Findings Group UID                (0040,A021)
   >Findings Group Recording Date     (0040,0023)
   >Findings Group Recording Time     (0040,0024)
   Second item ---------------------------------------------
   >Procedure Context Flag            (0040,A603)
   >Findings Group UID                (0040,A021)
   >Findings Group Recording Date     (0040,0023)
   >Findings Group Recording Time     (0040,0024)
   Third item ----------------------------------------------
   >Procedure Context Flag            (0040,A603)
   >Findings Group UID                (0040,A021)
   >Findings Group Recording Date     (0040,0023)
   >Findings Group Recording Time     (0040,0024)
   

   Each attributes of items contain the proper value. Now comes the Observation Category Sequence. It contains only one item. (See above). How can you define this sequence for each Findings Group? If you define one, it will belong to the first or the second or to the third item?

3. Section C.6.10 Observer Context Module on page 47.

   Table C.6.10-1 defines the Attributes that identify the Current Observer of the Findings Group or the source of
   Linguistic Evidence read or heard by the Current Observer and documented in the Findings Group as
   Supporting Evidence.
   

   My Comments

   Same question: which Findings Group? There is no references in the Table C.6.10-1.

4. Section C.6.11 Procedure Context Moduleon page 50.

   The Attributes of Table C.6.11-1 identify the Procedure or service that produced the Evidence that evoked the
   Observations contained in this Findings Group.
   

   My Comments

   Same question: which Findings Group?

5. Section C.6.12 Observation Context Module on page 51.

   Table C.6.12-1 defines the Attributes that identify the Observation Subjects 
   observed either directly or
   indirectly by the Current Observer of a Findings Group.
   

   My Comments

   Same question: which Findings Group?

6. Section C.6.13 Observation Module on page 54.

   • Table C.6.13-1 specifies the mechanism for conveying the Observations that constitute the Findings of a 
     Findings Group.

   •      ...       each item of the Observations Sequence (0040,A730) shall also 
     contain all of the Attributes of the Relationship Module, except as noted in the following sentence. If the

     My Comments

     The Table does not contain the Attributes Relationship Module. What does it mean that it shall contain all of Attributes of the Relationship Module?
     
     

   • 4) a Referenced Observation denoted by Referenced Observation UID (0040,A173) and Referenced 
     Observation Class (0040,A172) or a Referenced Findings Group denoted by Referenced Findings Group UID 
     (0040,A022).
     

     My Comments

     I can not see these Attributes in the Table. (Yes you can find it in another module, but not in this Module and not in this Table)

7. Sections C.6.14 - C.6.28 Modules on pages 56-78

   Table C.6   ...
   

   My Comments

   Each Observations can contain these Modules depends on which SR IOD you are using. How will you make a conntact between these Modules and each Observations?
