I suspect this discussion happened on code4lib before the thread got cross-posting to LLD XG where I first saw it. There are undoubtedly a ton of diverse use cases, but that doesn't mean APIs are the best solution. Here are some spitball possibilities for "not just manifestations" and "we need page numbers". http://example.org/frbr:serial/2/citation-apa.{bcp-47}.txt http://example.org/frbr:manifestation/1/citation-apa.{bcp-47}.txt?xyz:st artPage=5&xyz:endPage=6 I'm imagining an xyz ontology with startPage and endPage, but we can surely create it if something doesn't already exist.
