Hello: John is in a book club, and they are reading a title that has no print equivalent . The members of the book club are on a wide range of platforms. Many of the readers have selected larger fonts for their reading pleasure. They want to turn to a passage in the book and it would help them to all be on the same page. They want to go to that common page, and they know their system supports Go-To the virtual page in the same way they go to a page in a title that has a print equivalent. They are accustomed to go to the beginning of a page and then move down to the paragraph they want to review. Mary works for a publisher who is looking for a way to use a standardized way to insert virtual page numbers in their title. They could just develop their own approach, but Mary thinks it is better to use standards established for this purpose. When They market the title, they will say that it has xxx virtual print pages, which should be approximately the same across the publishing chain for print or digital only titles.

Just to give an idea of what we're considering, we have developed a skeleton for an algorithm that could parse an EPUB file and generate "locators" at defined intervals. One of the questions we are tackling now is where the locators live after generation. In practice, reading systems do not typically write to the EPUB file, meaning that if the locators are generated upon loading, they would potentially live in a "virtual" space accessible to the reading system. This virtual locator list would be usable by the reading system for things like search or navigate to page but would not appear in text or in the DOM. This is the question we need help with. Our understanding is that locators need to be accessible to assistive technology, though the user may turn them on or off, which means we need to explore how locators need to be changed to accommodate this. Any advice you can provide on: * the use cases of page numbers with AT, * what use cases need to be supported, * are there other ways page numbers/locators need to be exposed to the user or AT Please let us know if there are any questions, or if this is best discussed on an upcoming call, our next one is April 29th at 10AM ET. Thanks, Wendy Co-chair, EPUB3 WG
