Bridge Requirements

This bridge:
  • is only supported on Microsoft Windows.

Bridge Specifications

Vendor World Wide Web Consortium
Tool Name XML Document Type Definition (DTD)
Tool Version 1.0
Tool Web Site http://www.w3.org/TR/2000/REC-xml-20001006
Supported Methodology [XML Modeling] Data Store (Physical Data Model) via XML DTD File
Incremental Harvesting
Multi-Model Harvesting
Remote Repository Browsing for Model Selection
Data Profiling

Import tool: World Wide Web Consortium XML Document Type Definition (DTD) 1.0 (http://www.w3.org/TR/2000/REC-xml-20001006)
Import interface: [XML Modeling] Data Store (Physical Data Model) via XML DTD File from W3C XML Document Type Definition (DTD) 1.0 Import bridge: 'W3cXmlDtd' 10.1.0

The bridge directly uses the DTD file as input.


Bridge Parameters

Parameter Name Description Type Values Default Scope
File The bridge uses an XML DTD file as input. FILE *.dtd   Mandatory
Elements content name XML elements can carry some textual data, in addition to carrying named attributes and sub-elements. The XML DTD specification refers to this mixed content data as #PCDATA. The bridge will map this concept into an attribute which name can be customized using this option. STRING   #PCDATA Mandatory
Collapse Level By default, the bridge creates a Class for every DTD element.

To reduce the number of objects you can collapse multiple Classes together.

This option allows you to specify when to collapse a Class:

'None' - No collapsing: every DTD Element becomes a class and every DTD Attribute becomes an attribute..

'Empty' - Only empty Classes (i.e. without Attributes) should be collapsed into their parent classes.

'Single Attribute' - Only DTD elements with a single attribute and no children should be collapsed into their parent class.

'No Children' - Any DTD element that has no child element will be collapsed into its parent class.

'All' - All DTD elements for which it is possible will be collapsed into their parent class.

None  
Collapse Star Determines whether DTD elements with an incoming '*' link should be collapsed:

'True' - Collapse into their parent class.
'False' - Do not collapse into their parent class.
BOOLEAN   False  
Class Type This parameter defines how relationships between elements should be interpreted. If you are converting the DTD into a UML object model, you may use this option to determine whether a Class Type (UML concept) should be created when collapsing an Element into its parent Element.
'True' - Create UML ClassTypes whenever possible. You can set this value when converting to a UML object modeling tool.
'False' - Insert the Attributes of the Element about to be collapsed into its parent's Element. Set this value when converting to a relational data modeling tool.
BOOLEAN   False  
Any Determines whether to create a Class/Entity for the 'ANY' pseudo-element.

'True' - Represent 'ANY' by creating a Class/Entity.
'False' - Ignore 'ANY' altogether.

For example, in the following DTD fragment:
<!ELEMENT tag ANY >
the ANY content can be represented or skipped entirely.
BOOLEAN   True  
Strict Multiplicity Determines how '(a|b|c)*' should be interpreted:

'True' - To the letter interpretation: 'a', 'b' or 'c' can be repeated zero or more times in any order.

'False' - Interpret it as '(a?,b?,c?)' except that the order does not matter.
BOOLEAN   True  
Generate IDs Determines whether additional attributes should be generated to create Primary and Foreign Keys.

'True' - Generate an Artificial Attribute for each DTD element to represent this primary key - Foreign key relationship,

'False' - The model will not contain keys.
BOOLEAN   False  
HL7 Set this option to 'True' if you are importing HL7 DTD and you want to perform HL7 specific treatments. BOOLEAN   False

Mapping Comments
     
Association Element Content each time the element is not a PCDATA or occurs more than once in an element list
Aggregation   True
AssociationRole Element Content  
Multiplicity element occurrence +', '*', '?' or none
Source   based on Elements hierarchy
Attribute Element/Attribute An Element imported as a class type, a PCDATA element used with an occurrence "zero or one" or a REQUIRED attribute
Name Element Name For HL7 the HL7_name property
PhysicalName   For HL7 the element name
Position   Order in the element list
DataType   SQL_LONG_VARCHAR, SQL_VARCHAR
Name   Text (for PCDATA Elements), CDATA (for Attributes)
CandidateKey   No equivalent in XML DTD. A Primary key is created if artificial attributes are generated.
Class Element  
Name Element Name For HL7 the HL7_name property
PhysicalName   For HL7 the element name
ClassDiagram   No equivalent in XML. A main class diagram "Main" will be created to contain all elements.
ClassType Element when the Element is imported as an Attribute of its parent (depends on the bridge options).
Name Element Name For HL7 the HL7_name property
DerivedType   Only in HL7
DataType Data Type See datatype conversion array
Name Name based on the T property in the attribute list for a PCDATA element
UserDefined   True
DesignPackage   No equivalent in XML. A main package "Logical View" will be created to contain all elements.
ForeignKey   No equivalent in XML DTD. Foreign Keys are created based on Associations if artificial attributes are generated.
Grouping Element Content  
GroupingType element type ,' , '|' or none (leaf)
Multiplicity element occurrence +', '*', '?' or none
Position   Position of sub-element in element content
Index   No equivalent in XML DTD. An index is created for each generated key.
IndexMember   No equivalent in XML DTD. An index member is created for each key attribute.
StoreModel DTD The model is built using the elements contained in the XML file. The Entity will be expanded when used.
Name   Computed from the XML DTD file name.
TypeValue Enumerated Attribute Type  
Name Name Name in the list, e.g, red.
Position   Order in the file
Value Name
