Bandwidth-efficient document translation

Open roybaer opened this issue 8 years ago • 3 comments

Hi! I just wanted to share the following idea:

Basics:

  • Odt and docx files are ZIP archives
  • Only the textual content is needed for translation
  • Files within ZIP archives are compressed individually

The following process could therefore (perhaps dramatically) reduce the network bandwidth required for document translation:

  1. Read the entire document file into RAM using javascript
  2. Copy the (compressed) file chunks corresponding to the textual content to a new data structure and attach a new ZIP header
  3. Submit the stripped-down (but still correct) ZIP file for translation
  4. Reintegrate the response into the original ZIP and update the header
  5. Put everything in a data URL and let the user save it to disk

No API-changes would be required, because the client-side script basically just strips unneeded content (e.g. pictures) from the ZIP (i.e. odt or docx) file and apertium does not care about those anyway.
