At last week's PRISM Face to Face meeting at Time Inc. (NY), Linda Burman raised the question of how (STM) publishers were using PRISM beyond RSS. I gave a brief presentation of how we at Nature were using PRISM: RSS (well you all know about that), Connotea (our social bookmarking tool), SRU (Search/Retrieve by URL), and OTMI (Open Text Mining Interface - which we'll shortly be making available for wider comment). Be interested to learn if anyone else is using PRISM in other ways.
