SPECIFICATIONS
Tool: Object Management Group / Common Warehouse Metamodel (CWM) XMI version 1.0 to 1.1 via CWM XMI File
See http://www.omg.org/cwm/
Metadata: [Metadata Management] Metadata Repository, Data Store (Object Model UML Class Diagrams, Physical Data Model, Logical Data Model)
Component: OmgCwmXmi version 11.2.0
OVERVIEW
Generates an XML file compliant to the Object Management Group (OMG) Common Warehouse Metamodel (CWM) XML Metadata Interchange (XMI) file format. There are multiple versions of the CWM metamodel and XMI format, therefore make sure you generate the appropriate OMG CWM XMI version for your target tool.
REQUIREMENTS
For instructions on how to Import the generated UML XMI file, please select the exact bridge (with the tool name) from the list of bridges rather than using this generic bridge.
FREQUENTLY ASKED QUESTIONS
Q: Which version of CMW file is supported by my tool?
A: Contact the vendor to obtain the exact version of their supported CWM metamodel and XMI format. You can also check out the OMG web site for more details of their valid combinations of metamodels and XMI formats.
Q: Exporting to IBM DB2 Warehouse Manager v8
A: Contact the vendor to obtain the exact version of their supported CWM metamodel and XMI format. You can also check out the OMG web site for more details of their valid combinations of metamodels and XMI formats.

Bridge Parameters
| Parameter Name | Description | Type | Values | Default | Scope | ||||
| File | Generates an XML file compliant to the Object Management Group (OMG) Common Warehouse Metamodel (CWM) XML Metadata Interchange (XMI) file format. | FILE |
|
Mandatory | |||||
| Model | The target model type: 'UML' Export the logical model only as an instance of the metamodel for the CWM Object resource package (e.g. an entity/table is an instance of CWM: Class with the logical/business name as name). Note: the CWM Object Metamodel a subset of the UML Class Diagram Metamodel. 'RDB' Export the physical model only as an instance of the metamodel for the CWM 'Relational' resource package (e.g. an entity/table is an instance of CWMRDB: Table with the physical table name as name. 'UML and RDB' Export both logical and physical models as separate instances of the metamodels for CWM Object and Relational resource packages respectively. Note that no dependency relationships are established between both logical and physical models. 'OLAP' Export your model as OLAP only model. Use when exporting to OLAP objects to Oracle OWB. |

RDB | |||||
| CWM version | The CWM version to write in the header when generating the file. | ENUMERATED |
|
CWM 1.0 | |||||
| Schema mapping | How to export a Table when it is not connected to any MIRSchema: 'Use Packages names' Create a CWM's RDBMS Schema for the Package the Table belongs to. 'Use default name' Create only one default RDBMS: Schema and put all the tables that are not connected to a MIRSchema in it. Use the option 'Default Schema name' to specify the name of this the default Schema. |
ENUMERATED |
|
Use Packages names | |||||
| Default Schema name | The name to use for the default RDBMS schema. This option is ignored if 'Schema mapping' is not set to 'Use default name'. | STRING | |||||||
| Export Index of Key | Determines whether to export the Index associated to a Primary Key or a Foreign Key: 'True' Export the Index. 'False' Don't export the associated Index. |
BOOLEAN | True | ||||||
| UUIDs | Determines whether to export the object's 'Universally Unique Identifier' when known. The UUIDs of the source model may not be compatible with the target tool: 'True' Export the UUIDs. 'False' Don't export the necessary tags. |
BOOLEAN | False | ||||||
| xmlns:CWM | There is currently no standard for URIs. This option allows you to change the URI for the CWM namespace if the destination tool expects a special URI that is different from the default URI. | STRING | org.omg.CWM1.0 | ||||||
| xmlns:CWMRDB | There is currently no standard for the URIs. This option allows you to change the URI for the CWMRDB namespace if the destination tool expects a special URI that is different from the default URI. | STRING | org.omg.CWM1.0/Relational | ||||||
| xmlns:CWMOLAP | There is currently no standard for URIs. This option allows you to change the URI for the CWM namespace if the destination tool expects a special URI that is different from the default URI. | STRING | org.omg.CWM1.0/OLAP | ||||||
| xmlns:CWMTFM | There is currently no standard for the URIs. This allows you to change the URI for the CWMRDB namespace if the destination tool expects a special URI that is different from the default URI. | STRING | org.omg.CWM1.0/Transformation | ||||||
| Verbosity | How verbose is the output. 'False' Normal verbosity. 'True' Additional information is printed in the log. |
BOOLEAN | True | ||||||
| XML Indentation (pretty printing) | Controls the pretty printing of XML, for the purpose of opening the generated file in a text editor. E.g. 'space characters' Several space characters as indentation. 'tab key' Tab character as indentation. 'empty' No indentation which leads to a more compact file |
STRING | |||||||
| Print DTD reference | Some XML viewers, like Microsoft IE, refuse to display an XML file if it includes a reference to a DTD file that is missing. This bridge normally does not provide the 'cwm.dtd' file. If you need the DTD file please find and copy it to the same directory where the XML file is. 'True' Print a DTD reference to 'cwm.dtd'. 'False' |
BOOLEAN | True |
