We're lower-casing all input in PHP, but preemptively rejecting uppercase client-side with the html validation. Need to allow uppercase letters on the HTML side to make it more user-friendly.

Example: text under copyright or description fields under book info doesn't render (maybe uses White as color?) in Bombadil theme.

The log output is:
PHP Fatal error: Class 'XSLTProcessor' not found in /var/www/sites/courses/wp-content/plugins/pressbooks/includes/modules/export/class-pb-export.php on line 388, referer: https://x.com/introbusiness2x31x1/wp-admin/admin.php?page=pb_export

Could be as simple as:

This is the 2nd most serious issue currently with PDF exports.

When images are exported in PDF form, they seem to align as in web views, but text does not wrap around them and they may not be sized as in web views.

For example: on this page, the Goal Setting chalkboard image looks good in the web view:
https://courses.candelalearning.com/collegesuccess2x30master/chapter/setting-and-reaching-goals/

But has no text wrapping and may be larger in the PDF export:

In class-pb-wxr.php, I think there was a merge error or something. At line 101, your code has

if ( 'part' == $post_type ) {
  $chapter_parent = $pid;
}

$pid = wp_insert_post( $new_post );

While the code from pressbooks has

$pid = wp_insert_post( $new_post );

if ( 'part' == $post_type ) {
  $chapter_parent = $pid;
}

The $pid needs to get defined before it's assigned to $chapter_parent

CC has strongly encouraged us to add the round icons from https://creativecommons.org/about/downloads#Icons to our attribution statements.

Put the following fonts (I believe package below only includes Decour; Ostrich Sans available from link) in place in Candela (instructions included in package) so that it can be used by PDF export CSS (and presumably other CSS like in themes, although that is not the specific need).

Ostrich Sans: http://www.fontsquirrel.com/fonts/ostrich-sans
Decour: http://www.myfonts.com/fonts/latinotype/decour/
https://drive.google.com/open?id=0B57_zROT3c1HODFoTVNNZkZ0dzg

Not sure on the IE version, but witnessed that EDIT button does not appear in either Candela or Washington themes when using IE and LTI via Blackboard. Same user, same course can see EDIT button using FF or Chrome.

Maybe we should start doing at least a spot check on IE to make sure at least basic elements are in place.

Directions for adding the Oauth library aren't included in Readme.md, and this causes the creation of new LTI Consumers to fail.

page versions should store versioned attributions

A plain vanilla table like below renders full-width with a full-width border. If a table doesn't need to be full-width, it shouldn't be.

The border issue seems to have to do with the display: block; in the following style:

media="screen, print"
table {
  border-collapse: collapse;
  border-spacing: 0;
  max-width: 100%;
  overflow-x: auto;
  display: block;
}

<table cellspacing="0" cellpadding="0">
<tbody>

<td>Arch</td>
<td>Pen</td>
</tr>
<tr>
<td>Chowder</td>
<td>Maple</td>

In the section of Readme.md titled "Enable and Configure Pressbooks and Pressbooks Textbooks," step 9 directs users to Network Activate the Hypothesis plugin. But the plugin isn't there. Is this an artifact of moving from the standalone plugin to functionality provided by Pressbooks Textbook?

Currently, Lumen uses an export/import process to bring selections from one Candela course into another. The process works great, but we've recently discovered (been reminded?) that the crucial attributions metadata on each page does not travel with these exports.

The only known workaround is to use export/import to move Candela parts/pages, then manually copy every attribution on every page. Unsurprisingly, this is a very labor-intensive workaround and a number of our highest enrollment and most popular courses (eg, all the English comp courses, college success), require a lot of this type of remixing to tailor them for specific faculty/institutions.

We are also not clear on the differences between WP and PB WXR exports and whether one or the other should be preferred.

On catalogs with lots of tags, background color doesn't seem to grow. May be related to to the following style: https://courses.candelalearning.com/wp-content/plugins/pressbooks/assets/css/style-catalog.css

.catalog-sidebar {
    background-color: #3a3a3a;      
    height: 100%;

We were not planning to give Candela Subscribers privileges to access and edit any administrative areas of Candela, including their own user profiles, but such users can navigate to admin access if they click on the page title of any LTI Candela page:

to navigate to the public TOC, where they will see an ADMIN button that gives them access to view the admin TOC view, course user list, and the ability to view and modify their own Candela user profile:

It may be easier to just hide that TOC ADMIN button for all users, as Editors and more privileged roles that require Candela admin access have an additional admin navigation control in the Home | TOC toolbar.

exports from staging currently show this error when uploaded to customer (Oakwood) instance of D2L (unable to see logs)

It used to work, now it doesn't. In order to get another citation record, one has to update the whole page.

PDF exports currently only have Course titles in footers, which doesn't give sufficient context.

Ideally we'd have both Chapter (aka Part) and Page titles available for use on pages, so depending on design, the elements available for the following page would be:

1. College Orientation and Success Strategies = Course title
2. Chapter 2 Who am I and What are My Goals? = Chapter/Part title)
3. Setting and Reaching Goals = Page title)

https://courses.candelalearning.com/collegesuccess2x30master/chapter/setting-and-reaching-goals/

But in PDF export, only the Course title is currently available in every PDF page of the output

Currently, the Export view of a Candela course is not available to instructors (who typically have the Editor role) or students (who typically have the Subscriber role), which means any exports from Candela must be generated by Lumen support and then delivered to end users (faculty and students alike) through another means (eg, uploading exports to AWS and linking from there because it is not possible to upload files of typical export size to the Candela media library, which has a 3MB upload limit).

Better would be:

1. Faculty (Editor role) can view and generate exports.
2. Students (Subscriber role) can view/download export files.

It's another consideration if we want to give unauthenticated public users access to view/download exports.

Currently, the following Candela roles do not see the Export navigation in its normal place in the Candela admin left side menu, but do see Export navigation in the top toolbar of the Text admin view

Contributor
Author
Editor

Any role that can't see/access the navigation in one place, shouldn't see/access it in another. Lumen may want to change which Candela roles have access to Export (eg, we may decide instructors/Editors should have Export access), but that access should be a consistent privilege.

Some of the links made via this ThinCC don't fully load in Bb (eg, note missing left/right nav and content).

I will post the related ThinCC to Slack #dev referencing this issue.

Unfortunately, I need the Bb shell to make a working demo, so I'll be modifying it. but the Candela course at issue here is:
https://courses.candelalearning.com/biology11xdemo/

If you enter a new attribution with say a single quote mark in it (and maybe other special characters?) Candela erases all the attributions for that page. That really sucks after you've entered a bunch.

Can we let special characters through?

Looks like another library missing on the server:
1: /home/vagrant/kindlegen/kindlegen: not found

All H3s are now centered, which makes them hard to parse on a regular page. I think what may have happened is that there was a move to center H3s in decorative boxes that was applied to all H3s.

There is this:

media="all"
.bcc-box h3:first-child {
  text-align: center;
  margin: -2% -3% 15px;
  color: #ffffff;
  padding: 15px 0 15px;
}

And this:

media="screen, print"
h3 {
  text-align: center;
  font-size: 1em;
  font-weight: bold;
  font-style: normal;
  font-variant: normal;
  text-transform: none;
  letter-spacing: none;
  word-spacing: none;
  page-break-after: avoid;
  hyphens: none;
  -webkit-hyphens: none;
}

PDF exports don't currently output a table of contents (TOC) for the whole course on a page at the start. A style treatment for the TOC is on order, but we need to output it for it to be styled.

Bonus nice to have: TOC can understand and report page numbers of first PDF pages of Chapter/Part and Page.

The web view of the course has a TOC:
https://courses.candelalearning.com/collegesuccess2x30master/

The PDF export has no Course TOC:

Heretofore expected behavior (although not optimal, see below for optimal) was that an LTI link established in an LMS to a page marked "private" in Candela would not allow user access, currently by redirecting user to Candela home page.

I recently exported an entire Candela course to Bb, and most of the private pages behave as expected, but one actually lets the LTI user navigate to the private page.

The exported course is
https://courses.candelalearning.com/introbusiness2xmasterxdemo/
Example private page that does not allow LTI user access:
https://courses.candelalearning.com/introbusiness2xmasterxdemo/chapter/1-8-cases-and-problems/
Example private page that does allow LTI user access:
https://courses.candelalearning.com/introbusiness2xmasterxdemo/chapter/sample-assignment-congratulations-you-are-the-new-chair-of-the-federal-reserve/

If helpful, I can give anyone that has a Bb Coursesites ID access to a course that demonstrates this behavior.

Optimal behavior:
Private pages can be linked from LTI launches, but will only allow access to LTI users that have a Candela role in that course that would normally allow access to private pages (eg, Editor). This would be a win-win behavior, because it would enable us to distribute private instructor materials via LTI to the LMS. Extra points if the private page links could come into the LMS defaulted to be unavailable to students.

example:
https://courses.candelalearning.com/technicalwriting1x33x2/chapter/memos/

while the ThinCC refers to:

Viewed in Canvas as an LTI user with Editor role in Candela.

with Candela Advanced theme

with Candela Clean theme

The new Edit Navigation Links widget is super-useful, but falls below the fold so one has to scroll to it. We recommend reordering the widgets as per this image:

On further reflection, I realize we can't just simply give a Candela editor role to every user an LMS sends with an instructor role as some of our customers don't want every LMS instructor editing their master Candela courses.

Especially given that it's possible for an LMS user to connect to ANY Candela course they can guess the BLOGID for.

So far, I'm imagining that the easiest path to handle this might be to make Candela-LMS LTI role mapping configurable on the Candela side on a per course basis.

Another option I can think of is that all LTI users continue to be given the lowest Candela role (ie, subscriber), but that we provide a mechanism where a specific LTI user can request greater privileges (in such a way that we know which LTI user is making the request) and then Lumen support grants new privileges on a case by case basis.

There may be other solutions.

Change "Citations" to "Attribution" here:

CC have strongly encouraged us to add a link in the Citations tool for faculty to be able to visit the Licenses page on the CC website to review what each license means / allows / does.

current export from staging brings in only parts (not pages) in customer Sakai implementation (Cerritos) using Lesson Builder Sakai tool

For example, if you have any value in the 'Copyright Notice' then the export will fail.

Currently, we are relying on counting the number of LTI users in a subscriber role in a given Candela course in order to determine the number of enrollments in that course. That works great for the first term of that course's use, but Candela courses will get used over multiple terms, with multiple new LTI users, and so to do counts ongoing, we'll need to be able to count LTI users who access in a certain timeframe.

Probably most useful would be the ability to set start/end date filters that enable us to see accessing users over flexible time periods (given that customers have a wide variety of terms).

Importing a course that has accent marks in a page title (eg, Résumé) generates an error in Bb:

An error has occurred. The error recorded is:
The provided file could not be identified as a supported package format and therefore can not be processed.
For more information, see the detailed log.

The resulting ThinCC has XML in it like:

<item identifier="I_865_116" identifierref="R_865_116">
         <title>R&eacute;sum&eacute;</title>
</item>

Workaround: don’t put accent marks in page/part titles (eg, use Resume, not Résumé).

no click no work

This is the most crucial issue with PDF exports: no Licenses & Attributions info is exported.

For example, the attributions on this page:
https://courses.candelalearning.com/collegesuccess2x30master/chapter/assessment-technology-checklist/

are not exported into its PDF export:

A style treatment for these elements is on order with the designer, but we need to figure out how to output this info so it can be styled.

On Candela production (eg: https://courses.candelalearning.com/biology1x46master/wp-admin/tools.php?page=candela-thin-export.php)

Exports work well if you leave "Only pages marked as export" checked, but if you uncheck it, incomplete ThinCC is generated (see preview or below):

Can we implement the following preliminary PDF CSS rules to see how the PDF output looks to the designer from there for another round of adjustments? Ideally we'd use the following course currently on Production as a sample if it's possible for you to get that into your dev/test environments:
https://courses.candelalearning.com/collegesuccess2x30master/

<h1>, Book Title and Part Title: Ostrich Sans, 50pt, line space 60pt, centered
<h2> and Page Title: Decour Semibold, 36pt, line space 43pt
<h3> and Styled Boxes Title: Decour Semibold, 20pt, line space 24pt, centered (centered only in Styled Boxes)
<h4>: Decour Semibold, 14pt, line space 13pt
<h5>: Decour Light, 10pt, line space 13 pt, centered
<h6> and Image Captions: Decour Light Italic, 9pt, line space 13pt
<p> and all normal body text: Decour Light, 10pt, line space 13 pt

PDF Page Margins:
outside: 42mm (ie, right margin of odd pages, left margin of even pages)
inside: 34mm (ie, left margin of odd pages, right margin of even pages)
top: 22mm
bottom: 50mm

Is this extension installed?

I'm getting the admin warning telling me it isn't:

And later a fatal error telling me it isn't:

phpinfo(); is also telling me the oauth.ini is being parsed at /etc/php5/apache2/conf.d/oauth.ini, but the extension isn't displayed.

I also see in the vagrant build logs that it should have been:

If you put a string like 値カトエナ into citations, you get results like shown.

See example: https://courses.candelalearning.com/testnate/front-matter/attribution/

With ThinCC use, the button is confusing and mostly useless. There may be use cases for making manual links, but maybe could be addressed as needed by (temporarily) switching to another theme, or perhaps as a theme option.

In Candela IMSCC import, backslashes in HTML don't seem to be processed correctly, and either get stripped or interpreted as backslashes. This is proving annoying when importing content with inline latex.

I can work around this for now by escaping all the backslashes with another backslash.

See screenshots. In the Attributions/Licensing/Citations area of Candela, what should be the CC BY-NC license shows up everywhere as CC BY-N.

For example, in table below, unable to adjust so first column gets wider width than other columns.
https://courses.candelalearning.com/collegesuccess2x30master/chapter/stress/

When attempting to import a file, we get an error saying that the "Class 'XSLTProcessor' not found"

This can be solved (short term) by installing the XSL extension: apt-get install php5-xsl

Long term, this should probably be put into fm_apache_php.pp but I wasn't 100% sure it made sense for it to be there or in some other location, so I left it out.

After installing the XSL extension, imports get processed with no errors.

Example: https://courses.candelalearning.com/collegesuccess2x30master/chapter/using-test-results/

PDF exports don't currently output a table of contents (TOC) for each Chapter/Part on a page at the start of that Chapter/Page, which is now just a blank page with the Chapter/Part title. A style treatment for such a TOC is on order, but we need to output it for it to be styled.

Bonus nice to have: TOC can understand and report page numbers of first PDF pages of pages in Chapter/Part.

The TOC for this Chapter/Part would be:

The web view of the course also doesn't have a TOC, but we don't have users navigate to view Chapters/Parts, so we don't notice, like on this chapter/part:
https://courses.candelalearning.com/collegesuccess2x30master/part/you-and-your-college-experience/

In the PDF export, there is just a blank page at the start of each chapter/part with the chapter/part title:
