scenario can be reflected with a LISL script. For
this example we will assume that some of our
authors are using MUPPLE as their PLE platform.
Reaching beyond the before-mentioned activity
'Getting to Know Each Other', we focus on a
typical activity in the field of higher education:
collaborative writing.
In this concrete lifelong learning scenario, a
knowledge worker wants to collaborate with ex-
perts from other organizational contexts in writing
the concept for a new project. With a few clicks,
she creates a personal learning environment for this
activity that consists out of seven steps encompass-
ing actions on identifying and sharing background
literature, subsequently summarizing the state of
the art with the help of these documents, distribut-
ing section assignments to the collaborators, and
finally elaborating the text of the assigned parts
and reviewing plus proof reading it for quality
assurance. She benefits from earlier users of the
system who already configured several of the tools
she is going to use, most notably Scuttle, a social

bookmarking tool: MUPPLE already knows how
particular actions can be executed in specific tools
and which specific URLs address these actions.
Without really noticing, as she is using the
graphical user interface, MUPPLE in the back-
ground added a couple of additional lines to her
new activity script (see Figure 7). Most of the
lines 1-5 and 6-13 have been added by the sys-
tem automatically according to her intended use
of the actions that are reflected in lines 14-21 of
the depicted script. Actions and tools have to be
defined, while outcomes will be defined implicitly
on starting an action if not given. The definition of
an outcome is only necessary if its value is used
somewhere (not shown in this example). While
working on the activity, user interface interactions
are appended to the script (beginning with line 22)
in order to materialize what the learner did so far.
All the information of the script is used to rebuild
the semantic model behind and the web application
mash-up of the corresponding MUPPLE page.
