Tag sites in Sakai

I made a tags for sites interface and am using that in my flogging service/tool for Sakai. Now I want to tag lectures, or rather, resources. The problem is that I do not know how to access resources directly. I think I can, and so I will scan the APIs to do so. I think the interface could be about the same as my current tags work, just for resources not courses. Put the tool inside of a person’s home page, and let each person tag their own stuff and their own sites. Together again, for the first time…
