Viewing Document Schema File in Schema Viewer tab
A document schema file consists of segments, loops, composites, and/or elements arranged as nodes in a tree view. You can view X12, HIPAA, HL7, EDIFACT, and SWIFT types of document schema files.
To view the document schema file, in Project Explorer, double-click the .ds.xml file that you want to view. The file opens as a tab (Schema Viewer) and displays the following information:
• The left pane provides a tree view of all the nodes. You can click on the arrow ► to expand and view the child nodes.
The nodes are categorized as:
• Segments
• Loops
• Composites
• Elements
• Blocks (only for SWIFT file type)
Each node can include the following types of child nodes (HIPAA, HL7, EDI X12, or EDIFACT):
 
Node
Child Nodes
Root node
Segment and/or Loop
Segment
Element and/or Composite
Composite
Sub-element
Loop
Sub-loop and Sub-segment
Subsegment
Element and/or Composite
Subloop
Sub-segment and/or Sub-loop
For SWIFT file type, each node includes the following types of child nodes.
 
Node
Child Nodes
Root node
Block
Block
SubBlock and/or SubField

SubBlock and/or SubSubField
Block with ID value as 4
Repeat, Choice, and/or Field

• The right pane displays the properties (Name and Value) for the selected node. For more details, see Editing Document Schema File.
Key Points:
• If the library files such as Segment Library, Field Library, Code Value Library, or Code Set library are not linked based on the file type (HL7, HIPAA, X12, or EDIFACT), then the Configuration tab is displayed by default. The Schema tab is enabled only after you link the required files. For information to link these files, see Linking Library Files With Document Schema File.
• After the linking the required files, if you open the same .ds.xml file again, the Schema tab is displayed.
• Every schema file has its own mapping of Segment Library, Field Library, Code Value Library, or Code set library files.
Note:  These key points are not applicable for SWIFT file type.
