Re: Proposal: PDF alternative using HTML (ZIP/GZIP)

Hi Bill,

I'm going to let my suggestion die, this is just some comments regarding EPUB.


<snip>
if EPUB/PWP succeeds as the next-generation portable document format for OWP then it would be logical for browsers to similarly implement out-of-the-box.
</snip>


If we do go down this route, where browsers provide support for EPUB/PWP, then I agree that it will be easier to implement than PDF.

While I am very impressed in what PDF.js has managed to do, as you pointed out, it is very complicated.

But I would suggest that you give it some thought on how these files would be presented in the browser.

A user opening a document probably needs to have in mind what the view represents.

At the moment I worry that PWP might be seen as the main delivery method of EPUB, and the way it works (magic updating) would undermine EPUB being used for anything that cannot/shouldn't be updated.

At the moment I can show a PDF on a website, and users kind of understand that it is a PDF file, and what that means (e.g. they can download it to their computer, and it will remain there un-changed, always available, and does not perform network requests when it is opened).



<snip>
Of course there's a thousand ways to implement navigation/menus in a web page, the EPUB requirement that this be via a designated <nav> element simply makes for more interoperability.
</snip>


I'm really glad to see that assistive devices are being considered like this.

And when it comes to multi-page documents, I really do see the point in enforcing a navigation bar to be present, and for it to follow a very strict structure (says he who has created some of those nasty HTML navigation bars before now).

So personally, I want to see this requirement remain in place for EPUB files, as it forces people to build large documents correctly.

But there are times, like with a single page leaflet (with only a few words), or when you are just packaging up an existing webpage (e.g. "Save Web Page As" for later reading), where a navigation bar won't be appropriate.

And in terms of use cases (following on from another thread), a fairly common one I see is the "simple web page".

For example, some of the designers and developers I work with will create the basic website design in PhotoShop (yes, I know, not ideal), and then save it out as a PDF for the client to approve. Ideally those designers will learn basic HTML/CSS, working with the medium (media queries please), and package that up to send to the client before it's built "properly".


<snip>
That being said I do think that one major difference with documents/publications vs. simple Web pages is that hand authoring is much less of a consideration.
</snip>


Very true, I have really just been thinking of the cases where the document is being hand created (keeping in mind that I am a programer that frequently has to create the type of documents I've been focusing on).



<snip>
In that regard your point about a "Java program" also seemed misleading. There is a normative validator for EPUB (validator.idpf.org) as there is for HTML5 (validator.w3.org). There is no requirement by either standard that content be validated before being used.
</snip>


I only mentioned the Java program as it looked like it was required to package up the EPUB file.

I didn't really look at the source code, I just simply wanted to take my source files (folder) and compile it into an EPUB file.

If I used zip or gzip on the folder, it didn't seem to work (likewise doing the reverse on an existing EPUB file).

So without doing much more research, I suspect it is something custom (and if it does require Java, I won't be able to run that on my server, because I cannot install Java).

But given that all modern browsers / operating systems support PDF (either natively as per Chrome or via OS-bundled "helper apps" as per Safari with Preview) then if EPUB/PWP succeeds as the next-generation portable document format for OWP then it would be logical for browsers to similarly implement out-of-the-box. Which of course would be much much lighter-weight than PDF that requires either a totally separate app or a truly monstrous polyfill (in the case of PDF.js). That PDF.js was never workable in practice on devices with FirefoxOS is one datapoint about the gulf between PDF and OWP.

In the case where there is really no internal structure at all then even a stub <nav> element with only the single entry point can still help because it can link to the beginning of content, avoiding any header stuff. Of course there's a thousand ways to implement navigation/menus in a web page, the EPUB requirement that this be via a designated <nav> element simply makes for more interoperability. I don't see this as a huge burden given that this is precisely what <nav> was added to HTML5 to support (pre-HTML5 navigation was, and still usually is, cobbled together through a variety of divs/spans/buttons/tables/JS, which is challenging for assistive technology - and other semantic processing - to "decode".

That's a corner case, when we are discussing publications rather than just web pages but such simpler defaults could be part of a PWP/EPUB4. But this brings me to the last point in your email that I'd like to respond to..

The vast majority of documents and publications are generated by authoring tools and content generation systems, not humans. PDF is incredibly widely proliferated yet it's no easy thing to hand-author a valid PDF file (even for folks who wrote parts of the PDF specification). SVG is somewhat more hand-authoring friendly than PDF but in reality it's not going to be common for humans to hand-author vector graphics based on graphics states and affine transforms. Sacrificing features that improve interoperability, accessibility, and semantic proccessability in exchange for making it easier to hand author doesn't seem like a good tradeoff to me. Arguably this is true for OWP overall, now that most HTML pages are generated by tools like Wordpress and Drupal, even the templates for these sites are often tool-generated. But if we are specifically talking about an alternative to PDFs, which are 100% tool-generates, I don't think hand-authoring is what is going to matter.
> 
> So basically that you (and others!) may find hand-authoring EPUB "annoying" to me is just that - an annoyance not a fatal flaw. It is at least possible to do (unlike PDF). We can and should make some efforts to improve this (among other things easier hand-authoring may in some respects correlate to simpler machine-generation) but I don't see it as in any way one of the highest priorities even for a future PWP/EPUB4.
> 
> In that regard your point about a "Java program" also seemed misleading. There is a normative validator for EPUB (validator.idpf.org <http://validator.idpf.org/>) as there is for HTML5 (validator.w3.org <http://validator.w3.org/>). There is no requirement by either standard that content be validated before being used. That in the EPUB ecosystem a number of commercial distribution channels require content to validate is arguably a feature not a bug but it's nothing to do with EPUB as a format.  That PDF doesn't have any normative validation software is definitely (IMO anyway) a bug not a feature. That stems from it being originally a proprietary format (the first versions of the PDF manual made that very clear by opening with "PDF is the file format of Adobe Acrobat") and because PDF's not a modular format built on other standards like ZIP, HTML, and XML so there's no building-block concepts of validity to layer upon.

>> - With regards to "legal" documents, I think some of the discussion is conflating "self-containedness" (/reliability) with visual fidelity. In an N-screen world, with visual representation not the only way to communicate information, the idea that a particular view of content is the *only* way to represent normative information such as contracts, forms, etc. is pretty archaic. Of course it's good to have the option to create "WYSIWYG" documents and the Web does... fixed-layout EPUB 3 documents can use CSS positioning, SVG, or bitmap images. And EPUB already has a multiple renditions specification [1] so that you can combine fixed and reflowable representations into a composite publication, including the means to map between them.
>> 
>> - The core architecture of PDF is content "typeset at the factory" to ensure a consistent visual representation. PDF evolved from PostScript  so at core a PDF is a sequence of page images containing scalable vector graphics, images, and precisely positioned glyphs. The Web analog is a PDF file = an ordered sequence of SVG images (SVG having started life as an XML mapping of the PDF spec). This makes PDF inherently not mobile-ready (in terms of adjustment of content to different sized screens), not very accessible, and not very semantically intelligible in various machine-processing workflows. Computers can drive cars so clearly they can reconstruct text and structure from visual information, but it's a heuristic process. As Leonard indicates  it's possible in theory to create accessible PDFs but since the logical structure features were grafted onto PDF's sequence-of-page-images architecture years after the fact the result is pretty awkward which is one reason that most PDF creation tools (including many from Adobe) don't even attempt it at all, much less to the level needed to meet WCAG 2.0 standards (it is nearly impossible to fund PDF content that is actually conformant to the PDF/UA profile ). As well the W3C WCAG guidelines were designed to work with Web Standards based content, so don't map so well to PDF. After all if a sequence of SVG images was good enough we could scrap HTML5 and just use SVG everywhere.
>> 
>> To me it's pretty clear that the evolutionary vector of EPUB/PWP to make portable web publications truly first-class in the Open Web Platform will need to encompass both reliable and packaged content (as per today's EPUB) as well as unpackaged content (which PWP is exploring).  By no means should we consider the PDF is better for legal documents or really any documents than a truly Web-based solution. Of course that doesn't mean PDF will go away but logically EPUB 3 already delivers (with reflowable and fixed-layout content) a superset of the expressional capabilities of EPUB and with PWP work we will take things even further and make things even more Web-native. 
>> 
>> But I do think we need to tease apart the key attributes and not conflate "reliable" with "packaged" with "fixed-layout". Portable Web Publications need to support all of these attributes even though individual instances may choose which ones they fully deliver on. I would, with hesitation, even add "accessible" to this list of separable attributes. I would like all content in the next-generation portable document format to be accessible, but as a broad-based part of OWP it's not clear that this is realistic to set as  a baseline requirement (hence one thing IPDF is considering in conjunction with our EPUB 3.1 revision is separating accessibility requirements into a layered profile, separate from the base specification).
>> 
>> Regarding Nick's comment about whether we need "something that works immediately". Ultimately browsers and operating systems will natively support EPUB/PWP, as they already do PDF, so all that content will certainly work "immediately", but I take the comment as whether a "polyfill" is necessary. To me the "polyfilling"/"prolyfilling" content, especially when that content is deployed live to the Web, must be a choice the content publisher can make. It has to be an option as we can't assume specialized user agents will always exist. But such programmatic polyfills must be optional not mandatory. Cleanly separating content representation from implementation mechanism is critical to ensure semantics aren't lost in implementation, If we failed in that we would be worse than PDF, we would be back to PostScript in which the content was only the side effect of interpreting programs. 
>> 
>> So by way of example, it must be possible to represent content that is designed to be dynamically paginated without having to ship with it a JS implementation to do that pagination, especially since in a number of use cases whatever dynamic pagination that comes along with the content may not be desired. But if content served up online wants to deliver a default pagination implementation, it should be able to do so and have some confidence that it will be utilized where it makes sense and not where it doesn't. Not always an easy problem but the issue of when a polyfill associated with content is used vs. an external native implementation is not unique to publications. What we have to avoid is tying the content itself to particular code expressions. It's great to design something that will work really well with Service Workers. Not so good to make something that requires JS code based on Service Workers, particularly for structured content that needs to be machine-processed in a variety of ways.
>> 
>> And most of all I don't think we should even consider forking yet another effort on something different. We already have a "PDF alternative using HTML (ZIP/GZIP)", it's called EPUB, it's already widely utilized and is expanding into new segments of content publishing, and with the PWP work we're hopefully going to take that alternative much further towards full convergence with OWP.

One of those cases is to be able to be a quality container for ebooks.  Ebooks are expected to be read in an offline mode on devices that may not have any connectivity to the internet.  In these cases, online is simply not an option - therefore the PWP must work in a 100% offline mode.  The content creator ultimately has the choice to build their PWP the way they see fit.

Mainly because of the business case you brought up - an employee generating an offline-mode file for sharing and archival purposes.

That said, we also realize that there is potentially a gap in what software capabilities are today and what might be needed for a high-quality PWP to function as smoothly as a PDF would today.
>>>>>>>> 
>>>>>>>> To speak to your specific case - the PDF sales report.  Using today's technology, you could export that sales report as an HTML file, attach that, and open that in your browser.  It can be archived, the local copy can only be changed by the user, etc,  What is not yet native in most browsers is the ability to have a package of HTML files.
>>>>>>>> 
>>>>>>>> For the case of a completely offline file - something more static - PWP completely allows for that, as long as the package is created referencing static files that can be grabbed when making the offline package.  That is completely within scope and a use case that has been considered. PWP does go one step further and let you have files that reference external resources.  This would let you keep data charts up-to-date, Make quick updates to color schemes, or pretty much anything else you may want to update.  This is a feature - and optional.
>>>>>>>> 
>>>>>>>> From my perspective - the goal for PWP is to create a package format that makes sense for the future.  PDF has specific use cases where it is amazing - it has had many years to be adopted and honed.  Outside of those use cases,  PWP hopes to cover many things that PDF does not do.  That doesn't mean that PDF will be useless, as I imagine businesses will be exporting sales reports in PDF for the next 10 years (the same way people are still using CSV when there is XLSX format...)  But I believe that PWP aims to be a more versatile format than PDF which is it's differentiation.
