Thank you Leonard for clarifying Adobe's technology vector with DPS and yes I would agree that the impediments to broader adoption of digital magazines (as currently conceived) hasn't really been about the technology... well, at least not directly. Digital magazines have been very targeted to tablets, but tablet sales have stalled while smartphone consumption of content is soaring... the model of precisely designing various fixed renditions of beautiful pages makes sense in a tablet-centric world but is not as practical for the N-screen world we are converging on, with most users' primary screen being their smallest..., this demands reflow, which is a technical requirement (one that I believe that EPUB-WEB group needs to be keeping front and center, since it also relates to a11y, and more generally machine processability). I do also agree on the need for choice in regards to content types including reflowable text, scalable text/vector graphics, and bitmap images. OWP overall and EPUB 3 already fully support all these choices, albeit in the case of scalable text/vector graphics it requires a transformation from PDF page descriptions (which can be "theoretically" lossless if SVG is the output of the transformation). I realize DPS now supports PDF pages as a content type (I believe it was originally bitmap pages only) which does remove a translation step and simplify workflows for some publishers... that could definitely be done with EPUB since its content types are extensible but so far we have taken the position that we would rather stay more closely aligned with OWP rather than bolting on a very large additional technology which is, at least in some respects, redundant with respect to OWP capabilities (esp. SVG) and which would add to the "threat surface". EPUB-WEB work could revisit this question, of course, and if a grand integration could be done that pulls PDF in more to the OWP that could be interesting, but it would also be much more ambitious and again could create some redundancy. Personally I would vote for keeping focus for EPUB-WEB on the "native" OWP content types (HTML/CSS and SVG) while increasing efforts on PDF to HTML/CSS and SVG translation (which while mostly being an implementation activity might have some spec impact, e.g. font support in SVG is a known weak point in achieving a full isomorphism with PDF page descriptions). --Bill On Mon, Aug 10, 2015 at 10:59 AM, Leonard Rosenthol <lrosenth@adobe.com> wrote: > Bill, I am not sure why you believe that the current crop of digital > magazine isn’t getting customer traction – our customers think it’s working > acceptably.
