Feeds CSV import taxonomy and file I have an interesting use-case.

I have to import a lot of documents (+100) into a specific content type called "Resource".
This content type consists of few taxonomy fields (mapped to a vocabulary), some textfields and PDF file.

What should be the strategy when using Feeds module. Is it possible to have multiple taxonomy terms per field ?
For taxonomy terms : 
It is possible, simply delimit your values with commas in your taxonomy field CSV column, and in the Feeds mapping, select "Search taxonomy terms by: Term name" and "Auto create"

Make sure your Drupal field allowed number of values is set to Unlimited (or > 1)

For files: 


your file is external and given a URL, feeds will download it and store it
your file is already stored locally then the URI must be either


a stream wrapper (e.g.: public://import/myfile.pdf)
a relative path from your docroot
an absolute path on your system
