Philip, I am not sure what you mean by the distinction between "technical interoperability as data and service providers" and "interoperable in any meaningful sense." I assume you mean some greater level of functionality that OAI lacks. You may be right about that greater level of functionality, but the immediate concern of the research community today is the absence of the target content, not the absence of a greater level of functionality. To get that absent target content, we need to mandate deposit. And that deposit has to be mandated at the level of each researcher's own Institutional Repository (IRs), not an arbitrary array of independent Central Repositories (like PubMed Central). The researcher's institution is the primary research provider, sharing a stake with its researchers in maximising, monitoring and measuring the visibility, accessibility, usage and impact of their joint research output. The way to cover all of research output, systematically and exhaustively, across all institutions, disciplines and nations, is via researchers' own institutions, not by creating many independent disciplinary, national, interdisciplinary, and international Central Repositories. So by all means work to upgrade the functionality of the IRs and the OAI. But meanwhile, IRs are certainly good enough to be filled, today, with just OAI interoperability; and once they are thus filled, the world research community will be incomparably better off than it is now -- even without the greater level of functionality you (rightly) seek. And to fill those IRs, now, researchers' institutions and funders need to mandate deposit in their own IRs -- not in an arbitrary array of independent disciplinary, national, interdisciplinary, and international Central Repositories (such as Canadian PubMed Central, which is what my original posting was about).
