1.0. INTRODUCTION:
OLAT (Online Learning And Training) - Open Source LMS, is the web-based open source
Learning Management System (LMS) based on Java and is available completely free to edit. OLAT offers
a flexible online course system along with extensive features to guarantee learning and teaching
independent of time and place. It has been created especially for public institutions such as universities,
academies or colleges, however, it is also suitable for other businesses since OLAT can easily represent any
didactic concept or be used in any kind of learning environment.
OLAT can be modified to our needs depending on individual requirements and used in any
universities or study place.
2.0. MOTIVATION:
The potential student’s who wish to do online courses in the university are encouraged to take the
test online and this requires multiple types of questions. OLAT provides a set of question types such as
single choice, multiple choice and other types. But, there is no match the following question type. So, we
are going to add a new question type called ‘matches’ and hence improve the facilities of the OLAT system
and provide a better interface to the students.
3.0. USERS AND MODULES:
The administrator’s are users with this role have the whole set of rights within OLAT. In some
workflows, users with this system role are treated differently from the rest of the users, giving them access
to administrative functionality. They are involved in creating the test.
All registered and authenticated users within the OLAT system are assigned the user role.
The role allows for the basic functionality such as personal briefcase, browsing the repository, creation of
buddy groups and other. They are writing the test created by the administrator.
4.0. APPROACHES:
OLAT includes an editor for QTI files. The editor offers single and multiple choice, fill in blank
And free text as type of questions. Since QTI does not define different types of questions, the editor relies on a
naming scheme to identify the type of question. This is done via an encoded item id in the form
QTIEDITOR:SCQ:123 where QTIEDITOR denotes that this item was created with the OLAT editor, SCQ
3

denotes the type of question (other types are MCQ, FIB and KPRIM) and finally the number is a file unique ID. We
could see QTIEditorHelper for details.
It is important to note, that the editor does not allow working with arbitrary QTI files created by other
editors or manually. It can only edit questions which originate from the editor itself. If you do any manual changes
to the generated qti.xml file, your changes may get lost when loaded again in the editor or the item may not be
editable anymore. The qti.xml is parsed and converted into an internal structure within the editor. Upon saving the
file, the qti.xml is generated from scratch based on the internal structure.
The generated qti files are stored in,
PATH_TO_OLATDATA/qtiser/USERNAME/QTI_RUN_ID/qti.ser . The results of a test run are stored in
XML files based on the IMS QTI Results Reporting standard. The source of the questions is added to the results
reporting for further reference. The files are stored in
PATH_TO_OLATDATA/resreporting/USERNAME/QTI_RUN_ID.xml
So, we need to edit the java class files in the business logic layer that is involved in the creation of the qti
file, in order to create a new question type named matches.
5.0. FUTURE WORK:
Improving the user interface.
Providing even more features like different types of test formats.
