OpenXLIFF Filters

An open source set of Java filters for creating, merging and validating XLIFF 1.2 and 2.0 files.

With OpenXLIFF Filters you can create XLIFF files that don't use proprietary markup and are compatible with most CAT (Computer Asisted Translation) tools.

XLIFFChecker, an open source XLIFF validation tool, is now part of OpenXLIFF Filters. Its code has been ported to Java 11 and enhanced with support for XLIFF 2.0.

Converting Documents to XLIFF

You can use the library in your own Java code. Conversion to XLIFF is handled by the class com.maxprograms.converters.Convert.

If you use binaries from the command line, running .\convert.bat or ./convert.sh without parameters displays help for XLIFF generation.

Usage:

   convert.bat [-help] [-version] -file sourceFile -srcLang sourceLang [-tgtLang targetLang]
               [-skl skeletonFile] [-xliff xliffFile] [-type fileType] [-enc encoding]
               [-srx srxFile] [-catalog catalogFile] [-divatal ditaval] [-embed] [-paragraph]
               [-2.0] [-charsets]

Where:

   -help:      (optional) Display this help information and exit
   -version:   (optional) Display version & build information and exit
   -file:      source file to convert
   -srgLang:   source language code
   -tgtLang:   (optional) target language code
   -xliff:     (optional) XLIFF file to generate
   -skl:       (optional) skeleton file to generate
   -type:      (optional) document type
   -enc:       (optional) character set code for the source file
   -srx:       (optional) SRX file to use for segmentation
   -catalog:   (optional) XML catalog to use for processing
   -ditaval:   (optional) conditional processing file to use when converting DITA maps
   -embed:     (optional) store skeleton inside the XLIFF file
   -paragraph: (optional) use paragraph segmentation
   -2.0:       (optional) generate XLIFF 2.0
   -charsets:  (optional) display a list of available character sets and exit

Document Types

   INX = Adobe InDesign Interchange
   ICML = Adobe InCopy ICML
   IDML = Adobe InDesign IDML
   DITA = DITA Map
   HTML = HTML Page
   JS = JavaScript
   JAVA = Java Properties
   JSON = JSON
   MIF = MIF (Maker Interchange Format)
   OFF = Microsoft Office 2007 Document
   OO = OpenOffice Document
   PO = PO (Portable Objects)
   RC = RC (Windows C/C++ Resources)
   RESX = ResX (Windows .NET Resources)
   SDLPPX = Trados Studio Package
   SDLXLIFF = SDLXLIFF Document
   SRT = SRT Subtitles
   TEXT = Plain Text
   TS = TS (Qt Linguist translation source)
   TXML = TXML Document
   WPML = WPML XLIFF
   XLIFF = XLIFF Document
   XML = XML Document
   XMLG = XML (Generic)

Only two parameters are absolutely required: -file and -srcLang. The library tries to automatically detect format and encoding and exits with an error message if it can't guess them. If automatic detection doesn't work, add -type and -enc parameters.

Character sets vary with the operating system. Run the conversion script with -charsets to get a list of character sets available in your OS.

By default, XLIFF and skeleton are generated in the folder where the source document is located. Extensions used for XLIFF and Skeleton are .xlf and .skl.

The XML type handles multiple document formats, like XHTML, SVG or DocBook files.

Default XML catalog and SRX file are provided. You can also use custom versions if required.

Converting XLIFF to Original Format

You can convert XLIFF files created with OpenXLIFF Filters to original format using class com.maxprograms.converters.Merge in your Java code.

If you use binaries from the command line, running .\merge.bat or ./merge.sh without parameters will display the information you need to merge an XLIFF file.

Usage:

   merge.bat [-help] [-version] -xliff xliffFile -target targetFile [-catalog catalogFile] [-unapproved] [-export]

Where:

   -help:       (optional) Display this help information and exit
   -version:    (optional) Display version & build information and exit
   -xliff:      XLIFF file to merge
   -target:     translated file or folder where to store translated files
   -catalog:    (optional) XML catalog to use for processing
   -unapproved: (optional) accept translations from unapproved segments
   -export:     (optional) generate TMX file from approved segments

XLIFF Validation

The original XLIFFChecker code supports XLIFF 1.0, 1.1 and 1.2. The new version incorporated in OpenXLIFF Filters also supports XLIFF 2.0.

Standard XML Schema validation does not detect the use of duplicated 'id' attributes, wrong language codes and other constraints written in the different XLIFF specifications.

All XLIFF 2.0 modules are validated using XML Schema validation in a first pass. Extra validation is then performed using Java code for XLIFF 2.0 Core and for Metadata, Matches and Glossary modules.

You can validate XLIFF files using your own Java code. Validation of XLIFF files is handled by the class com.maxprograms.validation.XliffChecker.

If you use binaries from the command line, running .\xliffchecker.bat or ./xliffchecker.sh without parameters displays help for XLIFF validation.

Usage:

   xliffchecker.bat [-help] -file xliffFile [-catalog catalogFile]

Where:

   -help:      (optional) Display this help information and exit
   -file:      XLIFF file to validate
   -catalog:   (optional) XML catalog to use for processing

XLIFF Validation Service

You can validate your XLIFF files online at https://dev.maxprograms.com/Validation/

Translation Status Analysis

This library lets you produce an HTML file with word counts and segment status statistics from an XLIFF file.

If you use binaries from the command line, running .\analysis.bat or ./analysis.sh without parameters displays help for statistics generation.

You can generate statistics using your own Java code. Statistics generation is handled by the class com.maxprograms.stats.RepetitionAnalysis.

Usage:

   analysis.sh [-help] -file xliffFile [-catalog catalogFile]

Where:

   -help:      (optional) Display this help information and exit
   -file:      XLIFF file to analyze
   -catalog:   (optional) XML catalog to use for processing

The HTML report is generated in the folder where the XLIFF file is located and its name is the name of the XLIFF plus .log.html.

Joining multiple XLIFF files

You can combine several XLIFF files into a larger one using the class com.maxprograms.converters.Join from your Java code or using the provided scripts.

Running .\join.bat or ./join.sh without parameters displays help for joining files.

Usage:

   join.sh [-help] -target targetFile -files file1,file2,file3...

 Where:

   -help:     (optional) Display this help information and exit
   -target:   combined output XLIFF file

The merge process automatically splits the files when converting back to original format.
