Okapi Framework - Filters

If you are using an Okapi Tool after the M9 release, you should be using the wiki online help:
http://www.opentag.com/okapi/wiki/index.php?title=TTX_Filter

Overview

The TTX Filter is an Okapi component that implements the IFilter interface for Trados TTX documents. The filter is implement in the class net.sf.okapi.filters.ttx.TTXFilter of the Okapi library.

TTX is a bilingual format used by some of the versions of the Trados tools, and supported by several other tools. There are no official public specifications available.

Processing Details

Input Encoding

The filter decides which encoding to use for the input document using the following logic:

• If the document has an encoding declaration it is used.
• Otherwise, UTF-8 is used as the default encoding (regardless the actual default encoding that was specified when opening the document).

Output Encoding

If the output encoding is UTF-8:

• If the input encoding was also UTF-8, a Byte-Order-Mark is used for the output document only if one was detected in the input document.
• If the input encoding was not UTF-8, no Byte-Order-Mark is used in the output document.

Line-Breaks

The type of line-breaks of the output is the same as the one of the original input.

Segmentation

TTX is a format where the target text cannot be represented if the text is not segmented. To resolve that issue, the filter has an option to force un-segmented entires to be output as a segment. This option is set by default.

Limitations

The <DF> TTX tag causes problems in some cases.

Parameters

The filter offers the following options:

Force un-segmented entires to be output as a segment -- Set this option to force un-segmented entries to be written out with a translation part, as a single segment.

Escape the greater-than characters -- Set this option to have all greater-than characters ('>') escaped as ">" in the output.
