Jats parser insert metadata in pdf


Using OJS

One journal, multilingual (PT, US, ES), installed OJS earlier this year, 8 past issues with total of 92 articles (imported by QuickSubmit plugin).
We are starting to use Jats Xml in our articles and one of the solutions is to use Texture and Jats Parser.

What i want to know is how can i add metadata to the pdf, like title,keyword and abstract in other languages.
