Hello all,
As most of you know, UP Valencia has developed the HTML5 Paella
Player for
Opencast Matterhorn [1]. We have just finished up with the bulk of
having everything OK for this semester recordings and we are going to
put some effort in adding features to Paella.
Our users have asked us to put the annotation service in Paella. Our
idea is just
adding the controls to create and read annotations from the Matterhorn 1.4
Service.
I think that some of you are working on that feature for the Engage
Player, and I don't want to break anything, so I am writing this mail
to see if there is anything I have to know before going on.
One issue that I have found is that there are two very different use
cases for
annotations, public annotations in which students create annotations,
the teacher can validate/delete it and everybody can see all
annotations from all students and teachers, and private annotations, in
which a user can only see his annotations. As far as I know today only
private annotations are supported, so we should write some code for
public annotations or maybe it should be better to have two different services,
to have both features.
I believe it's actually the opposite. While the annotation components
are mainly the work of the team from Osnabruck, my thesis project
needed private annotation features so that students could choose to
make an annotation visible only to themselves. The annotation service
currently has them all public by default, so I added that as part of my project.
I haven't quite sent that code back to Osnabruck yet for inclusion in
their work, but it's on my todo list :)
My thesis project is up in the MH-8060 branch on the Matterhorn SVN
server if you want to take a look and see how I implemented the private
annotation code.
