Nima,

This is only the second release.  I have spoken to some of the Sloan employees as well as Ernie, who has been doing some great work on specific aspects of SCORM functionality, but it remains unclear how we can integrate OpenCore functionality into .LRN.  I am sure that we will continue to speak about integrating portions of the functionality, but in my opinion, our project needs a little more time to mature before we will know how to combine the efforts effectively.

From my market experience, I see the need for OpenCore to remain a stand-alone module for some users; however, I hope that there is also a benefit to .LRN in conjunction with Ernie's work.

Any ideas are more than welcome.

Thanks,
Chip

Nima,

I will take the second error first, because it is easier.  All PDF generation requires that HTMLDoc http://www.easysw.com/htmldoc/ is installed on your server.  Kind of a hassle, but we needed the flexibility of PDFs for printable documents.

The first error is a little more difficult.  My first guess is that the create user functionality did not work on the openacs side, perhaps due to a lack of permissions for the login you were using.  The admin for OpenCore module has only been tested using a sitewide openacs admin login.  If user creation permissions are not the issue, would you mind capturing a log entry for me when you create a user with the OpenCore admin?

Thanks for your interest.

The package manager omitted the courses directory when I created the apm file.  Very strange.  I will try to fix that.

I don't think that mounting the application to /opencore would be a problem.  Can you find the users in the openacs "user" table?

Hi Jack,

First of all thanks for your work implementing LMS features on openacs. It is great!

I'm trying opencore package release 1.0.3a running with oacs 5-1/postgresql7.4.2/aolserver4.

Opencore package installs good. The opencore/www/courses created OK. As openacs user I added a company and a directory "1" was created in opencore/www/courses/1 as the doc said would be. Good. Supermanager created with no errors and I could login with this user and reach a UI for courses manager.

I uploaded a SCORM course created with reload editor I used to testing importing for Ernie's Lors package (it worked ok on Lors!). After uploaded zip file and unpacked it I had after clicking "Add new course"

Type: SCORM
Path: curso1/imsmanifest.xml

where curso1 is my uploaded course directory.

When I submit Import Course I had this error on background (log/error.log)

Bug-tracker at intellum.org is going to be used reporting bugs and patches?

I read this post https://openacs.org/forums/message-view?message_id=168874 from Ernie Ghiglione about Opencore and I agree when he said there is "a lot of opportunities to work with Jack on a robust SCORM/LMS implementation that not only fulfils the needs of corporations, but also the academic world".

I have some available time now and some basic skills on openacs programming and could be good colaborate on efforts building courseware features like you and Ernie are planning.

Is OpenCore a fork of .LRN?

Hi Chip,

sorry for late response.

i think scorm import problem i reported before was a mistake of mine. i tried again and opencore recognized imsmanifest.xml and could import it. any way i just emailed this file for you as you asked for.

now i have:

* supermanager view:

Course Details
webcam

Type:     SCORM
Suggested Length:
Authorization:     Required
Notification:
Command Line:     webcam
File Name:     imsmanifest.xml

* student view (after enrollment/catalog view):

Course Detail
Course Name:     webcam
Course Category:     Undefined
Description:
Enroll Action:     Currently Enrolled

i hope you and Ernie could work together on developing the best solution for course import. LORS is going to be great as importing and deliver tool for scorm and i think opencore UI and navigational features provided by this package could enhance courseware features in dotlrn. anything i could help be free to contact me.
