Hi all, I've been investigating the possibility of assigning DOI names to various resources. We have three different use cases, and given the structure of the DOI Registration Agency system, I'm not sure what the best way is to proceed. The use cases: 1. We've had several inquiries from faculty whose research funding requires them to publish a web site, and identify the site with a DOI name for citation purposes. 2. We'd like to assign unique DOI names to specific bitstreams within our institutional repository. Despite the fact that DSpace uses a handle server internally, the handles it assigns resolve to metadata/landing pages, and there doesn't seem to be a good way to create a reliable, persistent link to a full text PDF that will migrate easily to a different IR system if and when we choose to move away from DSpace. 3. We're investigating the possibility of publishing a couple journals, and would want to use DOI names to identify articles and related content. However, it looks like each existing DOI Registration Agency has a specific subset of content and services they work with -- journal articles for one, datasets for another, etc. -- and I'm not sure how to go about finding an agency that will let us assign suffixes in a way that works with our varied content. Any suggestions/experience would be greatly appreciated. Michael
