How much work is required of a publisher to prepare journal content for PubMed Central?
Many journals already create XML or SGML versions of their articles as part of the journal production process. These journals must only arrange to transmit their XML/SGML files to PMC together with associated image files and, as applicable, PDFs and supplementary data files. Some additional work may be needed, initially, to refine the journal’s process for creating XML/SGML, if the submitted data does not satisfy PMC’s technical standards.. A journal that does not currently produce XML or SGML versions of its articles would have to add this process to its production stream or contract with a vendor to create XML from the article source files.
