What is the easiest way to have a ‘database’ of translations for strings and maybe links?

I now have 4 languages and 2 versions so 8 documents, but I’d like to have all translatable strings together so I can maintain these in a single file. Ideally I can do a file where the key of the translation is one language (say English) and the translations are part of that. 

Something I can call like this

\translatephrase[English phrase][nl]
\translatelocation[../LMTX-Output/without-ids/en/file.pdf][nl][simple]

and where I can maintain all the translations a bit like this:

\translationentry[English phrase]{
\definetranslatephrase[nl]Nederlandse frase]
\definetranslatephrase[fr][Phrase français]
}
}

\translatelocation[../LMTX-Output/without-ids/en/file.pdf][simple][nl][../LMTX-Output/without-ids/nl/file-simple.pdf]]
\translatelocation[../LMTX-Output/without-ids/en/file.pdf][none][nl][../LMTX-Output/without-ids/nl/file.pdf]]


Where the \translatelocation command can be used inside an \externalfigure command and \translatephrase can be used as as text.

In the end I’d like to compile with 

context language=fr mode=simple mainfile.tex

Doable?
