Hi.
This idea is not new. I and others have discussed this at length in the
past. There are a few problems off the top of my head:
1. Renaming files will break any existing users of liblouis.
2. The concepts associated with multiple codes (grades,
contracted/uncontracted, computer braille, etc.) aren't standard across
all codes. For example, in English, there is computer braille, grade 1
(uncontracted) and grade 2 (contracted). However, as I understand it,
some codes have more than two "grades" and grade 1 and 2 aren't
necessarily uncontracted and contracted, respectively. English has two
computer braille tables (6 dot and 8 dot). In order for such
standardisation to be useful, it needs to take all of this into account.
3. A table probably needs to specify exactly what languages and
countries it is used in. For example, UEB isn't truly unified because it
isn't used in all English speaking countries. I imagine there are some
country specific codes that are actually used in other countries.

Would everyone look over this list of human readable table name please. If I
have left something out that should be in there please make a comment to me or
to the document itself. I only included tables that would be used to do
translations and not support files.
I would add that it might be a good idea to harmonize the file name at some
point. I realize that in many cases one file calls another but it would seem to
be a good idea to consider. At the same time a standard header could be
included to be able to reach the human readable names, grade number, language
and so on something like this:
# eng; 2; English UEB Contracted
The first column is the ISO 639-2 Code
(http://www.loc.gov/standards/iso639-2/php/code_list.php) second column is the
grade (0,1,2,3) of braille the third column is the human readable name.In this
way a computer program could look at the first line of all the tables, .ctb
files, and work out list of all of them for a particular language, grade of
braille or build a menu of human readable names.
Files would be renamed as follows: eng-ueb-g1.ctb
All translation tables will start with the ISO 639-2 Code followed by either a
code identifier in the case of unified language codes as are found in English
and French or the national 2 letter code
(http://www.spoonfork.org/isocodes.html) for example Swedish would be
swe-sv-g1.ctb this would address a situation such as exists in German with two
Braille code systems one for Germany itself and one used in Switzerland they
would be ger-de-g1.ctb and ger-ch-g1.ctb
just a thought.
