Learning Material Markup Language

Definition

Learning Material Markup Language (LMML) is both a framework and a series of educational modeling languages based on the the Passau Teachware Model (PTM).

The Passau Teachware Metamodel

“The Passau Teachware Metamodel describes generally the modular structure of eLearning contents. It can be instantiated for diverse fields of application like mathematics/computer science, operation research, financial planning or your own required field of application” ( [1], retrieved 12:11, 30 May 2007 (MEST)).

“The elearning content is organized modularly. It consists of various modules. Each module may contain further modules itself. The basic units of information in this hierarchy are called Content Modules, e.g. Definiton or Motivation. Their content can be structured as lists or tables, containing static or dynamic media objects, for instance picture, animation, text, which are linked with an open plug-in-interface.”([2], retrieved 12:11, 30 May 2007 (MEST)).

Passau Teachware Metamodel

The framework is extensible, i.e. individual elearning applications have to fulfill specific requirements but “modules types such as algorithms, descriptions or hints can be added as easily as existing types can be specialized”.

Passau Teachware Metamodel

“LMML modules can be associated with other LMML modules in different ways. The Passau Teachware Model provides following types of association: defined, illustrated and other. These types can be adapted and extended accordingly to the field of application. The single LMML modules and their association are described by metadata. Therefore, LMML provides a basic set of metadata: general (author, title, catchwords, etc), time-related (creation-, modification-, release-, expiation-date, etc.) and educational (difficulty, abstraction, ect.)”. ([3], retrieved 12:11, 30 May 2007 (MEST)).

Passau Teachware Metamodel

The DTD

Since the DTD for LMML is extensible, it is divided into several module files by the use of external parameters.

The driver module

Typically, one needs the LMML framework and its modules defined parameter entities. The single modules are "cmodel", "metadata", "datatypes", "multimedia", "table", "list", "link" and "charent". Each LMLL language is defined in a "driver module" that whill include other files. As an example, the DTD for Computer-Science teaching LMML-CS.dtd would include both this framework and extra extensions.

%lmml-framework.mod;
%lmml-cs-spec.mod;

LMML Computer Science Teaching DTD

Here is the DTD for the LMLL-CS driver module:

<!-- LMML-CS-Content DTD......................................... -->
<!-- file: LMML-CS.dtd..................................... -->
<!--  
    This is LMML-CS, a language for specifying teachware content from
    the domain of application of teaching and learning computer science as
    described in Christian Suess, Burkhard Freitag, Peter Broessler,
    "Metamodeling for Web-Based Teachware Management". In: P.P Chen,

    Paris, France. LNCS 1727, Springer Verlag,
    http://im.fmi.uni-passau.de/db/literatur.php3?key=SFB99

    It is an implementation of the XML binding of the teachware-specific meta-model
    described in Christian Suess, Adaptive Knowledge Management: A Meta-Modeling
    Approach and its Binding to XML". In: Proceedings 11. Workshop Grundlagen von Datenbanken,

    Conceptual Model

    This module replaces the LMML 1.0 Conceptual Model module and the LMML 1.0 Structure
    Modul. It implements the XML Binding of the structure of teachware formaly known as LMSML
    and describes the groupings of elements that make up common content models for LMML formaly
    known as LMCML.

    Conceptual units elements now are replaced by sections having corresponding type attributes,
    e.g. a <courseUnit> now is replaced by a <section type="course">.

    LMML has four basic content models:

    %Inline.class;            		   character-level elements
    %Incontentobject.class;    block-like elements within ContentObjects
    %Contentobject.class;      block-like elements ContentObjects
