Batch image export from Apple Photos

Deliverable: An Automator workflow to copy the contents of an Apple Photos library to an organized collection in the Finder. Skillset: I am looking for someone skilled with Applescript and/or Automator to create a portable workflow that batch exports original images and videos from Apple Photos to a designated folder in the Finder. User added metadata (in Photos) needs to be embedded in the files (or included in .xmp sidecars for RAW files) and the original capture date preserved. Photos assigned to user created Albums need to have the Album name added to the metadata as a keyword. Workflow needs to be portable and work on multiple Macs. Options to choose subsections of the Photos Library to export and whether to export Originals or use native Export. Can utilize other easily available app (like Adobe Bridge) if necessary but prefer all-in-one using Apple apps and capabilities.
