rights parameter in Signed URL

forums_noreply@adobe.com — Wed, 01 Oct 2014 21:39:30 GMT

Adobe Content Server: 4.2

Adobe Digital Editions: 4.0.98786

Platform: Mac OSX 10.7.5

Background:

I have a tool which builds a digitally signed URL for an ACS fulfillment. With this tool you can include the optional rights parameter and its valid values.

Behavior:

I'm seeing inconsistent behavior with narrowing the rights of a previously fulfilled book. ADE's 'Item Info' panel only displays the initial rights of the fulfilled book even after removing the book from ADE, deleting all .acsm files and then creating a new URL with different rights.

Steps to reproduce:

Package a book with no rights restrictions (display all, print allowed, copy allowed)
Create URL with rights, for example rights=$cpy#15#86400#
Download the book via the URL and it opens in ADE 4.0
View 'Item Info'. It will report (these are expected)
1. Viewing: on any device
2. Copying: 15 copy with an additional copy accrued every 1 hour 36 minutes, capped at 15 copy, on any device
3. Printing: on any device
Remove the book from ADE
Delete related .acsm file from the file system
Delete related .epub file from the file system
Create another URL for the same book but with different rights, for example rights=$prn#10#86400$
Download the book via the URL and it opens in ADE 4.0
View 'Item Info' for book in ADE. It will report the same rights as in step 4.

After step 10, I inspected the related .acsm file and it did reflect the new print rights but when ADE was launched using this .acsm file, the 'Item Info' reported the rights from step 4 which I did not expect.

I suspect what is happening is that once a book is initially fulfilled, its rights are immutable regardless of the associated local .acsm XML file. Yes, I've considered what if the end user alters the .acsm XML file to get more favorable permissions.

Lastly, the behavior I'm seeing may not be a real world situation but only related to our testing.

Anyone with insight on what I'm seeing would be greatly appreciated.

Rolling your own transactional report to replace operatorClient.jar

forums_noreply@adobe.com — Fri, 08 Aug 2014 21:22:30 GMT

I've recently been told by our ACS vendor that since we have now switched to their certificates (and not using Adobe's certs), we can no longer use the operatorClient.jar to generate transaction reports.

Therefore, I have to roll my own transaction reports from the adept database. I'm looking for an overview of the adept database.

Specifically, when a book is fulfilled, what tables get entries?

When a book is re-downloaded, what data is updated?

BTW, I have the adept schema in my Mysql Workbench EER diagram viewer.

Thanks in advance,

date and time of packaging

forums_noreply@adobe.com — Fri, 29 Aug 2014 15:46:22 GMT

Is there a way to determine the date and time of the packaging of a book in the ACS 4.2 from the adept schema?

In the resourceitem table, how is the modified column populated? I would like to initialize its value when a book is initially packaged and ingested into the ACS. When the content of the book is replaced, I'd like to update this column's value.

I know that I can determine the date/time of the encrypted file on the filesystem.

Thanks in advance,

Disappearing allowURLCollisionsOnReplace configuration item from packaging.conf file

forums_noreply@adobe.com — Fri, 11 Jul 2014 16:30:12 GMT

Problem: Disappearing allowURLCollisionsOnReplace configuration item from packaging.conf file

Steps to Reproduce:

edit /etc/packaging.conf
add com.adobe.adept.packaging.allowURLCollisionsOnReplace=true
save /etc/packaging.conf
service tomcat restart
watch 'cat /etc/packaging.conf'

Observation: After some amount of time (1 to 5 minutes), the configuration item com.adobe.adept.packaging.allowURLCollisionsOnReplace=true disappears from the /etc/packaging.conf

Once this happens, any replace packaging request fails due to the missing configuration item.

Environment:

Linux amlnx-ldd-acs01 2.6.32-431.20.3.el6.x86_64 #1 SMP Thu Jun 19 21:14:45 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

What is the resource download URL in the exported books.xml file?

What is the purpose of the resource download URL in the exported books.xml file? The following is an excerpt of a books.xml file.
