On this moment there is a number of tools allready developed and a number of tools on the wishlist. See also the tools page from 2011. The database will be freely available, so that people can build tools onto it, and re-use the data. That way, you can for example project the monuments on a map, or make other additional work with it.
Mass upload for Wiki Loves Monuments has so far been a tough thing to do, especially for the new and inexperienced participants of the contest.
Wikimedia Foundation developers have done a great job on preparing & fixing UploadWizard and enabling UploadCampaigns that we used in September 2011. It is limited to batch uploads of 50 files, and as of May 2012, has a feature which enables applying metadata across a whole batch. Users may nevertheless prefer a desktop uploading tool for larger batches or more careful preparation of uploads.
This will be worked out on a later moment, the idea is that countries which use Flickr can request here to import the pictures from Flickr to Commons. If countries use other upload (then Commons or Flickr) platforms make sure you know how you will import these to Commons.
