InDesign Tagging & Translation Process

indesign-xml-json.txt

1) Tag Content in InDesign files
2) Export from InDesign as raw XML (no XSLT)
3) Validate XML against XSD
  - Enforce attributes on select tags
  - Escape special problem characters
  - Should be simple enough to be one-size-fits-all
4) PHP translation script
  - Escape select HTML tags before JSON translation (to reduce data depth)
  - Transform XML into JSON via Saxon\C-PHP software
  - Unescape html tags
  - Validate final JSON output against JSON schema
  
  
* The JSON schema will be structured to enforce a common output structure.
  Hopefully most InDesign files will match a common visual format to allow
  for this, but we're preparing for the eventuallity that we'll have a select
  number of different layout structures to handle.

* The current iteration of the PHP script requires the installation of some
  custom software on the server (Saxon, and Saxon\C-PHP), as well as the ability of the
  SmartMover Command Line module to access and write to directories on the server.
