Question: Copyright issues in importing OA content to OA database

["Atanu Garai" <atanugarai.lists@gmail.com>]

Dear Colleagues

I shall be thankful for your thoughtful reflection on the issue 
of copyright issue applicable to materials submitted in open 
archives with copyright clearances by authors. We are developing 
few subject gateways (customised) with rich taxonomies, enhanced 
search facilities and multi-lingual access facilty as open access 
and want to import relevant full text content to this newly 
developed repository. We have arranged written authorisation for 
some amount of the content (2%), but it would be difficult and 
time consuming (and also manual at this point of time) to do that 
across the sea of content in that subject. Given this situation, 
I would like your comments and learned opinion on the copyright 
aspects of importing the content from OA to this new database.

Are there any possible restrictions from author's point of view 
in duplicating their deposit from one database to other? I guess 
it should not be. Also, what are the mechanisms of doing that 
through automatic means? (I understand the later is a technical 
question, but might also be related to automatic acquisition of 
copyright clearances from the authors).

Thanks
Atanu Garai
