In general, is there a reason to have different metadata formats from SRU vs OpenSearch? Is there a way to just have the same metadata formats available for each? Or are the demands of each too different to just use the same underlying infrastructure, such that it really does take more work to include a metadata format as an OpenSearch option even if it's already been included as an SRU option? Personally, I'd like these alternate access methods to still have the same metadata format options, if possible. And other options. Everything should be as consistent as possible to avoid confusion.
