This document provides an agenda and discussion topics for an Alfresco training session. It includes introductions, preliminary thoughts on Alfresco from a new user perspective, definitions of some technical Alfresco terms, and a countdown of real questions from users with proposed solutions ranging from 1-9 lines of code.

4. Preliminary thoughts
From a newbie’s point of view

5. Alfresco is hard to learn

6. Some new words (for newbies)
Aikau! Activiti!
AMP!
WebScript! Spring Surf!
FreeMarker!
CMIS! Content Model!

7. Is there another life?
!
"With even a few lines of code, you can
easily add useful functionality to Alfresco."
!
(April 4, 2014 by Jeff Potts)!

8. Disclaimer
!
Source code based on Alfresco CE 4.2.f !
and available at GitHub !
!
WARNING!!
Code for teaching purposes. !
Don’t try to compile it on your head.!

9. Countdown
Real questions from real persons

10. 10. Add a download button
Motivation. "When I get a shared
document link by email and click on it, the
result may not be accessible: sometimes
the preview is not working, sometimes I
can only see a simple picture, sometimes
my computer has no Flash Player... How
can I get the content of a document
shared with me?"!

11. 10. Add a download button
Quick Share!

content out of its limits."!

21. 8. Changing document extension
Motivation. "We are elaborating
documents on Microsoft Word, once the
document is closed we are uploading a
final version in PDF. Surprisingly, final
document has the same extension as
original (.DOC) although mimetype is right.
Users can't open PDF document by
downloading or by editing online because
local programs are associated by file
extension."!

26. 7. Setting create missing person
Motivation. "I have configured our LDAP
for identification because I don't want to
take care of passwords, but I don't want
everyone on this LDAP to have access to
Alfresco.!

27. 7. Setting create missing person
# Some authentication mechanisms may need to create people
# in the repository on demand. This enables that feature.
# If disabled an error will be generated for missing
# people. If enabled then a person will be created and
# persisted.

31. 6. Custom LDAP identification
Motivation. "We have several LDAP
branches, one for each mail subdomain,

attribute bindable is an UID which can be
repeated on every branch. How can I
identify my users?"!

53. 1. Site templates with folders
Motivation. "Someone recently asked how
to create Alfresco Share sites with a
default folder structure. Currently, out-of-the-
box, when you create an Alfresco
Share site, the document library is empty.
This person instead wanted to define a set
of folders that would be created in the
document library when a new Alfresco
Share site is created."!
