Define EXPRESS-X Schema

Note: This function can only be used with the EDMmodelConverter license key fully installed.
Menu path: Schemata>EXPRESS-X>DefineSchema
Invokes the EDMexpressXCompiler to compile one or more files, each containing one or more Express-X schemata. For each input schema an Express-X syntax check, an Express-X schema consistency check including a check against source and target Express schema, and an Express-X dictionary model creation is available. This is specified through command options.
Normally an Express-X schemata defines a mapping (conversion) of a data model defined by one Express schema (source schema), to a new data model defined by another Express schema (target schema). A legal special case is when the source and target schema are the same Express schema. All Express schemata referred to by the actual Express-X schema must exist as dictionary models in the EDMdatabase when this command is executed. The command Schemata>DefineSchema can be used to create a dictionary model of an Express schema.
The command Data>ConvertModel can be used to perform the actual conversion process defined by an Express-X schema.
Arguments:

File name:	Specify the name of the file(s) containing Express-X schema(ta). If more than one file is specified, delimit each file name with a comma. The wild card symbol "" is also a permitted character in a filename. The default file extension is ".xpx". When activating the Select* button, a window is opened to allow browsing the directory structure and select the desired files.
Diagnostic file:	Specify the file name for diagnostic information generated by this command. If no file name is supplied, all diagnostic information will be presented in the EDMsupervisor output window. When activating the Select button, a window is opened to allow browsing the directory structure and select/specify the desired file.

Options:

accumulating command output:	A global option that appends the command output to the EDMsupervisor output window. Otherwise the output window is refreshed and only the last command output is displayed.
clear all options:	Unset all Schemata>EXPRESS-X>DefineSchema command options except [accumulating command output].
storing source:	Specifies that the Express-X schema(ta) will be stored in original form in the EDMdatabase. This source can later be retrieved and displayed by the command Schemata>EXPRESS-X>ShowSchemata command.
deleting existing schemas:	Specifies that the existing Express-X dictionary model(s) with the same name as the resulting Express-X dictionary model(s) from this compilation will be replaced by the new dictionary model(s).
parse only:	Specifies that the Express-X schema(ta) will be checked for syntax errors only.
no dictionary model:	Specifies that no Express-X dictionary models will be created by this invocation of the EDMexpressXCompiler.
map inheritance:	Specifies that map inheritance will be enabled during this invocation of the EDMexpressXCompiler.
continue storing on error:	Enforces the EDMexpressXCompiler to create and populate Express-X dictionary model(s) of erroneous schema(ta). Only dictionary models of schema(s) compiled without any errors can be stored as a dictionary model(s) in the EDMdatabase when this option is unset. NOTE: This option should be used with care as it may lead to unpredictable consequences, possibly fatal system failure during a conversion process defined by such an erroneous Express-X dictionary model!
sdai warnings:	This option enables the EDMexpressXCompiler to report as warnings, all failing EDMsupervisor operations during the actual compiler invocation.
errors only:	Warnings will be suppressed.
html error listing:	Specifies that compilation errors will be presented in HTML format by the EDMsupervisor configured Internet Browser.
map inheritance report:	Specify that a report of map inheritance should be written to the EDMexpressXCompiler diagnostic report. This option is effective only when the [map inheritance] option is set.
