Changes at Dom level for Pagination

brady: use cases have been on list for while, one use case is styling

… useful for content creators

<tzviya> use cases: http://www.w3.org/dpub/IG/wiki/UseCase_Directory#Pagination.2FDOM_interaction

… implementers, e.g creating ebook reader, no idea how to enter paginated mode

… turn pages, note visible pages, select text across pages. no apis exist

… often use internal APIs, webkit has some, CSS hacks like using columns or frames/Javascript

… doesn’t work with fancy page styling, semantics that it is a page is lost

… cannot use private port of webkit in ebook readers ?

… need to be able to state it is a book with pages

… listed many use cases

… this is summary of problem, need public API for handling pagination, details not clear yet

… need to understand a design, then API for control

… DOM should be able to handle pages, possible extensions

dauwhe: discussed at CSS F2F a few weeks ago, peter linss co-chair and tag member

… box tree api

… separate from DOM, could navigate, all pagination defined

… deprecate geometry apis in DOM and move to box tree api

… seems good

brady_duga: is this a DOM for boxes?

dauwhe: can move around boxes and deal with them, especially element fragmentation across boxes
... or pages

<Bill_Kasdorf> The people who are working on overlapping structures may be able to make some useful contributions to this issue

ivan: if this CSS work really happens then really need to be involved in this
... how does current API work when some tries to re-paginate

<david_stroup> https://www.npmjs.org/package/boxtree

ivan: re annotation, what is the anchor that is used for an annotation for a page?

brady_duga: depends on implementation

brady_duga: depends on the implementation

… find known anchor elements

… some are more fragile than others

… re pagination, depends, webkit just reload document, using printing architecture

… with columns, re-flow

… re-pagination means starting over

… what was behind the question?

ivan: just wnated to clarify

brady_duga: tricks to start re=paginating from current page, but earlier pages might start at strange locations

ivan: webit has API but other tools also have APIs, are these other APIs public or private?

brady_duga: haven’t looked, but there are browser demos

… use different mechanisms, details not clear

… issue of native code

ivan: this group cannot decide what is in the DOM, but could list solutions that are public with pros/cons

… realistic

brady_duga: not clear, have looked at WebKit one

… other approaches are mostly browser hacks or custom ports

<dauwhe> http://dev.w3.org/csswg/css-overflow-3/#paginated-overflow

fjh: maybe a task force is appropriate for box tree work, to include annotations or dpub, depends on chartering

dauwhe: have posted on how to handle overflow, see link above

tzviya: print and page are different

… could also talk about other non-scrolling views

<Bill_Kasdorf> +1 to "non-scrolling view" instead of "pages"

… next step, think how we might work with CSS group on box tree work

<tzviya> action @brady_duga draft basic needs of pagination API

<trackbot> Error finding '@brady_duga'. You can review and register nicknames at <http://www.w3.org/dpub/IG/track/users>.

ivan: use dpub pagination repository

<tzviya> action duga draft basic needs of pagination API

<trackbot> Created ACTION-23 - Draft basic needs of pagination api [on Brady Duga - due 2014-09-29].

brady: box tree in CSS WG or where?

dauwhe: peter linss is driving this, figuring out context, suggested joint TAG CSS work

brady: we might want to do something at TPAC as a joint session

<azaroth> +1 to joint TPAC session

tzviya: brady, will you be at tpac?

brady: yes

<tzviya> action tzviya plan CSS + pagination API meeting

<trackbot> Created ACTION-24 - Plan css + pagination api meeting [on Tzviya Siegman - due 2014-09-29].

<clapierre> I just registered with no problems and paid ;)

tzviya: other comments

none

Pagination - layout & markup update

dauwhe: request new publication location for WD

… some think latinreq since not updated since march, obbiously not familiar with w3c time scales

… added use case where text moves from 1 column into multiple columns

… common design, hard to do in CSS

ivan: no problem, can update WD

… watch out for moratium for TPAC

<liam> [moratorium on publishing - 24 October through 3 November ]

two publishing moratorium later this year:

* 24 October through 3 November during TPAC 2014 [1]

* 19 December through 5 January 2015

<tzviya> action tmichel publish updated version of latinreq with Dave

<trackbot> Created ACTION-25 - Publish updated version of latinreq with dave [on Thierry Michel - due 2014-09-29].

discussion of when to publish

dave: plan to publish next Tue, 30 Sept
... will prepare draft

… have to deal with table cells and some other items, but need to ask what might be missing or where more work is needed, so good to publish

tzviya: stem section needs more work

… want tables that align on a character, such as for accounting books

… align on equals sign (??)

… everyone that speciallizes in areas should take a look and see what they can add or update

… I’ve been working on pagination when customers try to print ebooks

… need some chemistry examples

… physics, math

<Bill_Kasdorf> +1 to vertical alignment on an arbitrary character that needs to be specified--common examples: . ) + = etc.

… even scrreen captures would help, Dave can then respond

call for volunteers met with silence

dave: it would even help more if I can use some of the documents themselves, realize it might be an issue

pkra: MathML specification has some examples

… such features make it hard to implement MathML, solution here might help

tzviya: exactly the sort of thing we are looking for

dave: right

Other Business

brady: CSS meets Thur, dpub Thur/Fri, why not schedule joint meeting on Thur

tzviya: will be looking at this tomorrow

ivan: scheduling might be a challenge, many joint meetings

dave: TPAC includes time every day for ad hoc meetings, does it not? could this be used?

ivan: schedule depends on WGs, some don’t observe those slots
... if you have info on when CSS group might have slots that would help
