XML Interface Toolkit
The XML interface toolkit provides mechanisms to import and export data in XML format. Arbitrary structured XML data is mapped to according UBIK® objects and its properties by a mapping specified in a separate mapping configuration file. Both files have to be specified in the interface command file additional to the default parameters.
 | The XML data file must use the correct encoding, e.g. UTF-8! |

Workflow
Import
- Create a XML data file to be imported in UBIK® according to the description for the mapping configuration
- Use the Interface Manager to create a proper interface command file specifying the required server parameters, folder and file locations
- Manually start and test the import by executing the interface via the Interface Manager
Export
- Use the Interface Manager to create a proper interface command file specifying the required server parameters, folder and file locations
- Manually start and test the export by executing the interface via the Interface Manager
Parameters
The general parameters, marked by Import/Export, are equivalents of the settings used by UBIKSTUDIO to connect to a database, please refer to its settings section for a detailed description.
The parameter DataView is used only for export purposes and defines the name of a UBIK® View object. In an export process the XML toolkit
- evaluates the view hierarchy and its objects
- exports an object as defined in the mapping
- in the same hierarchy as placed in the view

| RecordLifeTime | Import/Export | Duration how long records are valid before they will be requeried for changes by the kernel; -1 to turn off |
| WorkingFolder | Import/Export | Defines a folder where temporary files will be placed and deleted after processing |
| DataFile | Import/Export | Import: File path to XML data file to be imported; Export: Exported XML data will be stored in this file |
| DataMappingFile | Import/Export | File path to file containing the XML mapping information, both for import as well as export |
| DataView | Export | Name of a UBIK® view object defining the scope and hierarchy of exported objects |
| DataObject | Export | Guid of a single UBIK® object to be exported |
| DeleteFile | Import/Export | Defines whether or not the specified DataFile should be deleted after processing |
| LogFolder | Import/Export | Defines a folder where log files will be created into; if set a log file will be created always! |
| LogFile | Import/Export | Optional: defines a certain log file name; it not set the system will create an arbitrary one |

Mapping configuration
The XML data is converted into according UBIK® data (objects, property values,...) by applying a mapping between XML elements / attributes and UBIK® MetaClasses / MetaProperties.
Sections of mapping file
A mapping configuration file consists of two distinctive sections for the general import and export configuration, labeled as <Import> and <Export>, respectively.
Each such section consists of multiple sections describing the mapping of UBIK® MetaClasses to XML elements, labeled similar to the name of the related XML element. These class related mapping sections (also called ClassMapping) consist of sections for defining
- possible key properties, labeled <Identifiers>
- general properties, labeled <Property>
- references for objects, labeled <Reference>
- relations between objects, labeled <Relation>
- possible child objects, labeled <Object>
| The mapping information must be enveloped by a XML tag <UbikXMLMap>! |
Section: Import / Export
- Configuration of the general import and export mapping parameters
<Import EvaluateReferences=”1” EvaluateRelations=”0” DataEnvelope=”UbikXMLData”>
…
</Import>
<Export EvaluateReferences=”1” EvaluateRelations=”0” DataEnvelope=” UbikXMLData” EvaluateUTS=”1”>
</Export>
…
</Import>
<Export EvaluateReferences=”1” EvaluateRelations=”0” DataEnvelope=” UbikXMLData” EvaluateUTS=”1”>
</Export>
Attributes
| Attribute | Values | Description |
|---|---|---|
| EvaluateReferences | 0 or 1 | Set to 1 if references shall be evaluated (default = 1) |
| EvaluateRelations | 0 or 1 | Set to 1 if relations shall be evaluated (default = 1) |
| DataEnvelope | Text | Specify XML envelope (root node, default = UbikXMLData) |
| EvaluateUTS | 0 or 1 | Set to 1 to export UpdateTimeStamp of objects (default = 0) |
 | The default envelope for the XML data is <UbikXMLData> and can be modified via the mapping configuration settings. |
