You can access Data Mapper to map source schema elements to target schema elements.

Prerequisites:

To open Data Mapper applet:

...

  1. Go to Develop > Services > Data Transformation > Data Mapping.

     

  2. Click Create New. 

     

  3. Type the name and description of the new mapping activity in the Name and Description text boxes.
  4. You may find Metadata option. This feature is available in Beta version only. Type the keywords in Metadata. iMap will use these keywords to fetch the mapping for future use. All the keywords are stored in Adeptia secure cloud that will help iMap to fetch the mapping suggestions.  

  5. Click Data Mapper. A file - startMapper.jnlp will get downloaded to your computer. Double-click the file to view the Data Mapper screen. Click here to know how to map source and target elements.

    Info

    If you are starting the Data Mapper on your system for the first time, then a warning message is displayed that prevents you from starting this application. Ignore this message and click Start to continue.

    Info

    If you have read-only permissions, you can view a mapping activity in read-only mode. You can view the applied mapping, create new mapping rules, edit existing mapping rules and even run the simulation. For details, refer to the View Mapping in Read-Only Mode section.

  6. Expand Advanced Properties to set options for splitting data. You can split the source data into different chunks. You can specify the size of chunks in terms of the number of records. In the output, however, only one file is generated at the location specified in the target activity. To know more about splitting data, refer to the Splitting Source Data.

    Info

    You can set the Advanced Properties at any time of the mapping activity.

  7. Click Save to save mapping.

Validate XSL

Validates the generated XSL file.

Global Custom XSL Before

Adds a custom XSL code at the top of the mapping XSL.

Global Custom XSL After

Adds a custom XSL code at the bottom of the mapping XSL.

On Demand demand (optimized) loading of XML Schema tree

If the XSD is complex, then this option allows you to process Process only the root level element and ; not the complete XSD, if the XSD is complex. Only when When you expand the hierarchy elements, it processes the child elements and loads them into memory. The hierarchy elements expansion is now displayed in the applet. This option is applicable only on XML schemas. It optimizes the processing of XML schemas and loads the XSD elements only up to 2 levels in the source and target panels. You need to click a hierarchy element to load its further child elements.

Cache Included Schemas

This is applicable to all XML Schema which uses XSD. This option sets Set whether or not to cache the included XML schemas instead of inlining them as specified by the XML schema specification. Tree Expand This is applicable to all XML Schema which uses XSD.

Tree Expand Level for Optimized Loading

Defines the hierarchy level up to which the source and target files will be displayed for the schema loaded in Data Mapper. Hierarchy level is defined in the Tree Expand Level Dialog, which is opened when a user clicks this menu option. By default, its value is 3, that is, Data Mapper will display the hierarchy of source and target files for the respective schema up to level 3.

Easy Schema Parser Configuration

Defines the hierarchy level up to which the source and target files will process the schema to load it into the Data Mapper. You can define the hierarchy level in the Tree Expand Level Dialog box, it appears when you click on this menu option. The default value in the Tree Expand Level Dialog box is 10. This means that the Data Mapper will display the hierarchy of source and target files for the respective schema up to level 10.

Namespace

Manages Namespace.

Enable DBQuery caching

Enables DBQuery cache. This implies that if the same DBquery is fired on another element, it will generate the result from the existing query, instead of creating a new connection.

Search Element

Searches an element in the Source or Target schema hierarchy on the basis of Wild Card character(s) Comments, Data Type, Current Mapping Rules, Documentation, and Extension Node Element in the tree node of the Data Mapper.

Set Data Viewer Record Count

Sets the maximum number of records that can be shown in the data viewer.

Custom Auto Map Options

Adds a custom option for the Auto Mapper.

Value Map

Adds an option for value map.

Enable Quick Splitting

Splits data at the source end and merges at the target end automatically.

Import Mapping

Maps the elements in a pattern similar to an existing mapping.

Set Character Set Encoding for Data Parsing

Sets the character set encoding for the target schema before mapping the data elements.

Create Context Schema Definition

Contains the name of the context variable that you want to map to another element.

Streaming
Streaming
Streaming Mode: Streaming is useful while working with large files or documents. Streaming processes files by streaming the part of a file rather than loading the whole file into memory. You need to enable streaming to process large size file while mapping Source and Destination elements but before enabling you must follow some streaming guidelines. This option is supported only with XSL Version 3.0.

Set Font for MappingSets the font for mapping elements.

 

Output Settings

Exclude Result Prefixes: Excludes a namespace prefix from the target element.

CData Section Elements: Defines the CDATA elements for the target schema which will be displayed on the Output section of the Debugger screen.

Filter Unmapped Elements: Filters the elements or attributes from appearing in the target XML.

Indent Output XML: Generates an indented mapping output (XML).

titleEnabling Filter Empty Elements

To enable Filter Empty Elements, you will have to change the jar name manually. Following are the steps to change the jar name.

  1. Go to ….Adeptia-installation-path\AdeptiaServer\ServerKernel\etc\launcher.properties
  2. In the launcher properties file search for JAR:SAXON.
  3. Rename old saxon9pe.jar (old jar name) to saxon9ee.jar (new jar name)
  4. Restart kernel and web runner.

Handling Saxonica in v6.9.1

 

With upgrade to Adeptia Suite v6.9.2, existing customers using Adeptia Suite v6.9.2 will be automatically rolled back to the older version (i.e. saxon9pe.jar) of Saxonica. If you want to use Filter Empty Elements feature, follow the steps mentioned above for changing the jar name.

After you have upgraded Saxonica to ee version in latest version, you must run regression testing to ensure that all you’re existing mappings are working fine.

Mapping Functions Panel
The Mapping Functions Panel displays all mapping functions that can be used to map source and target schema elements. Mapping functions are supported by XSLT. However, the Data Mapper also includes some customized functions, which are not standard of XSLT. Refer to Using Mapping Functions for details on mapping elements using these functions.  


In addition to the mapping functions, an option of XSL Template is also displayed on the Mapping Functions Panel. This option enables you to Add XSL Template and further manage XSL templates from the Manage XSL Template screen.
