I've started my work at BEIC[1] and yesterday I've had a sort of revelation: their work on METS structural maps is the exact librarian equivalent of what we do at Wikisource with ProofreadPage[2] page transclusions. It's clear we can learn a lot from BEIC. See yourself, this is a scan where every image was manually mapped to the structure of pages, "chapters" (which are also OPAC entries) etc. on the left. Doesn't it immediately make you think of the Index namespace and <pagelist /> tag?[3] http://131.175.183.1/view/action/nmets.do?DOCCHOICE=2244270.xml&dvs=1411563364754~190&locale=it&search_terms=DTL12&adjacency=&VIEWER_URL=/view/action/nmets.do?&DELIVERY_RULE_ID=7&divType=&usePid1=true&usePid2=true All this is based on an open standard, METS, and its only required section, the "structural map" (of the digital document). https://en.wikipedia.org/wiki/METS#The_7_sections_of_a_METS_document Apparently, no other digital library does this job. BEIC and Wikisource may be the only ones in the world and of course they don't share a standard. :( Even the BEIC viewer is a local "hack" on top of ExLibris Primo, I/they don't know if there's any free software for METS. I didn't find any mention of METS in "our places" so I run to tell you all.
