This is the technical description of a DBT Translation table. If you want more general information about languages and template choices, please see the list of templates.
Initially, the language table for braille translation is determined by the selected template, and may be changed using the Document / Translation Tables menu. Using those menus does not require use of the table designator. However, to switch to a different translation table partway through a file, one must enter a DBT code and the designator for the table to switch to. For switching secondary languages within a base language table, see the [lng~X] command. For switching from one base language to another, see the [lnb~...] command.
The Danish tables support print-to-braille and braille-to-print translation of Danish-language literary text in contracted, partially contracted (grade 1), or uncontracted Danish braille. The American Computer Braille Code (CBC) is also supported.
Braille-to-print translation is supported for this language. However, braille-to-print translation may not be perfect, therefore beware that errors can occur. If you find errors or have suggestions, please send both the *.dxb and *.dxp files along with an explanation to: email@example.com. Please be sure to include sample files!
There are no special limitations.
No secondary languages are supported. However, it is possible to switch to any of the available translation tables listed in DBT. (See the [lnb~...] code below.)
Computer Braille Code (CBC), as defined by the Braille Authority of North America, is supported.
It is also possible to switch to any of the available translation tables listed in DBT (see the [lnb~...]code below), many of which do support various technical codes, such as for mathematics or computer notation, or which support “unified” treatment of technical notation as well as literary text in the base language associated with the table.
The following DBT translation codes are available when using the Danish table.Any other translation codes used will be ignored, or indeed may cause unexpected results.If using an alternative translation table, i.e.when switching to another base language table by means of the [lnb~...] code, please refer to the relevant topic and available codes for that table.
[/] may be embedded within letter-groups that would normally be contracted, to prevent the contraction.
[ab] is equivalent to [g2]
[cz] switches to "direct braille," wherein braille is directly represented using the North American ASCII-braille code. (This is sometimes called "no-translate" or "computer grade 0")
[g1] switches to "grade 1" (uncontracted) braille.
[g1.5] switches to "grade one-and-one-half" (partially contracted) braille.
[g2] switches to "grade 2" (fully contracted) braille. This is the normal mode.
[in] is equivalent to [g1]
[lnb~...] (for switching to another base [primary] language table)
[lng~en] switches to English language.
[lng~da] or [lng] switches to Danish language.
[tx] resumes normal translation, ending "direct braille."
The table is designed to work with the following groups of characters:
All ASCII printable characters.
Accented letters and punctuation marks typical of French, German, Italian, Spanish and Danish
British pound sign (£)
The above is a general guide only (see "General Notes" section at the beginning of this document).
Working with Hans Rasmussen of the Institute for the Blind and Partially Sighted in Denmark, a partnership facilitated by Techno-Vision Systems Ltd. of Northampton, England, Duxbury Systems began developing these tables in June 2003. The primary source was "Den Danske Punktskrift 1993," with information on later changes to that standard provided by Mr. Rasmussen."Forkbra," a public-domain Danish braille translation program, was also used to generate sample texts.
