The use of aided translation types is deprecated, but is supported for compatibility with earlier versions of OmniMark.

If you are building filters or other types of batch translation programs, you can use OmniMark's aided translation types to simplify your code.

The submit, do sgml-parse, and do xml-parse actions allow you to direct input to scanned or parsed within a normal OmniMark program. The using output as and output-to actions let you control where your output will go. Aided translation types simplify matters by automatically scanning or parsing input from a source specified on the OmniMark command line, and outputting directly to the destination appropriate for the type of translation.

The cross-translate translation type is used for conventional processing chores. It sends input directly to find rules; output goes directly to #main-output.

The up-translate translation type is used to add markup to data. It sends input directly to find rules and sends output to #main-output, just as in a cross-translate. However, it also sends a copy of the output to the parser. The parser does not produce any output, but it will raise errors if the markup it receives is incorrect. This checks the validity of the markup produced.

The down-translate translation type is used to parse data into another form (which may or may not contain markup). A down-translate sends input directly to the parser; output goes directly to #main-output.

The context-translate translation type is used to convert data from one format to another using a particular markup as an intermediate format. A context-translate sends input directly to find rules and sends the output of the find rules to the parser. Output from the markup rules goes to #main-output.

You cannot use a process rule in a program that uses an aided translation type. (Though you can use process-start and process-end rules.)

There are also some rule types designed specially for use in aided translation programs:

• find-start
• find-end
• document-start
• document-end

Aided translation types take their main input from the command line or files named on the command line. However, you can still use submit, do sgml-parse, and do xml-parse within the program. Note that you cannot use do sgml-parse or do xml-parse in a cross-translation.
