The SDL Trados Package Filter is an Okapi component that implements the IFilter interface for SDL Trados SDLPPX and SDLRPX files. The filter is implemented in the class net.sf.okapi.filters.sdlpackage.SdlPackageFilter of the Okapi library.

Processing Details

This filter is an extension of the Archive Filter. It reads the input package, detects the SDLXLIFF files for the specified language pair, and uses the XLIFF Filter (with the okf_xliff-sdl) to process the content. Each SDLXLIFF file inside the package corresponds to a sub-document in the Okapi filter events.


  • Reading an SDLPPX file and writting it back produces another SDLPPX file, not an SDLRPX file.
  • See all the limitation for the XLIFF Filter.
