I am working on updating the hyphenation patterns for Dutch for TeX, 
libhyphen, etc. The last time they were updated was end of 1996 after a 
spelling change. In 2006, there was again a spelling change. The old 
patterns do not support them and are missing a lot of new words. Our 
collection for word list and spelling checker has grown with at least 
100,000 words since then. We have also more hyphenation patterns but in 
2007 was the last time somebody worked on this experimentally and that 
is unfortunately undocumented and abandoned.

The Trennmuster project I know for years and have made some minor 
contributions in the past. Also on the advice of the creator of the 
Frysian hyphenation patterns, the approach of Trennmuster would be good 
for the new hyphenation patterns for Dutch as we have identical 
transcription changes when hyphenating.

Unlike German, Dutch has many compounds with a joining hyphen, e.g. 
zwart-witfotografie, toe-eigenen, normalisatie-instellingen and 
opera-uitvoeringen. These hyphens have priority for hyphenation over all 
other hyphenation locations. Preferred hyphenations is

..... ..... normalisatie-
instellingen

but when absolutely needed, also is possible

..... ..... ..... norma-
lisatie-instellingen

.... normalisatie-instel-
lingen

I did not find any examples in the wordlist file, so I searched for an 
example German word that fits my problem and was not yet in wordlist, 
hence Alanin-Aminotransferase with possible hyphenations being

..... ..... Alanin-
Aminotransferase

..... ..... ..... Ala-
nin-Aminotransferase

..... Alanin-Amino-
transferase

What would the hyphenation pattern according to the wordlist file be?

Alanin-Aminotransferase;A·la-nin{-/==}A·mi-no<trans<fer=a-se

reasoning that the first part of the {/} is the non-hyphenated writing.

That was my line of thought. With your info below, it would be?

Alanin;A·la-nin
Aminotransferase;A·mi-no<trans<fer=a-se

and then use in TeX

Alanin"=Aminotransferase

Unfortunately, regular Dutch has a lot of these words so I need to have 
them in the pattern file (for LibreOffice, Firefox, Chrome) and cannot 
use Babel's "= for that. Looking forward to your thoughts on this. 
(Hoping Trennmuster will support this edge case.)

Thanks,

Pander

PS   Is this centered dot at the beginning of the line a typo?
