Using Bidirectional (BiDi) support for sensors and the bulk load program

Bidirectional language support is provided for Arabic and Hebrew languages.

BiDi text is stored and processed in different environments (platforms) and with different layouts. This BiDi text can be introduced in TADDM through sensor discovery, IdML books, Bulk loading, or APIs. Bidirectional layout transformation must be used to transform from an external layout format to the TADDM default BiDi layout format.

Bidi support for sensors

To deal with data that is discovered and contains BiDi data with different formats, you have to transform the BiDi format of all the discovered BiDi data to a BiDi Default Format. Following the Unicode standards, the BiDi Default Format parameters values are:
  • Text Type: Implicit
  • Text Direction: Left-to-Right (LTR)
  • Symmetric swapping flag: Yes
  • BiDi Shaping indicator: Not Shaped
  • BiDi Numeric indicator: Nominal
You can enable or disable BiDi Transformation for the data sensors.
The BiDi format is configured in one of the following ways:
  • Configuration of BiDi format used by external system prior to discovery. You must explicitly specify this method BiDi format prior to a discovery run.
  • Automatic discovery of BiDi format standard used by external system during discovery. This method BiDi format is identified based on data attributes and external system attributes or both, that are discovered by the sensor. The identification of BiDi format is based on the algorithm taking into account some or all of the information or data that is discovered by the sensor from the external system.
During discovery configuration you can specify which of these two format options that you prefer. If you prefer the first one, it is also possible to specify the BiDi Profile to be used during discovery.

Bidi support for the bulk load program

Discovery adapters create the IdML files in the Discovery library. The Discovery Adapters write data into the Discovery Library. The discovered data can contain BiDi data. In this case, a BiDi transformation is needed for this data to transform the data to the default BiDi format.

The BiDi support for the IdML data is provided in the Bulk Load program. The Bulk Load program configures the needed BiDi format for the loaded data from the IdML files depending on the User BiDi configuration. You can configure BiDi format for each Management Software System or use an automatic BiDi format detection option. See Configuring bidirectional format for the bulk load program for more information.
