Six of the main EML's are: CDF, LMML, Targeteam, TML,PALO, and OUNL-EML. 

This ones can be categorize in two groups. The first group consisting of the first four mentioned above which seems more sophisticated specifying learning content and structure. TML can be distinguish as the one that provides for describing highly specific content.   However,  this group appear not to provide for modelling following a pedagogical approach. Also, they are unable of expressing executable knowledge about the model, with the exception of TML. 

The second group consists of PALO and OUNL-EML which can be categorize as the ones closer to the definition of an EML as "a semantic rich information model and binding, describing the content and process within units of learning from a pedagogical perspective". The PALO is limited when defining individual tasks. 

In terms of interoperability, it can be notice that there is low cohesion between EML's included in this two groups because of well marked difference in its elements and attributes. 

About there procedence, all this EML's were developed based on academic initiatives except CDF that was developed by an institute.

Learning about "OUNL-EML"

I am now learning about OUNL-EML. This EML

provides semantic specification for the development of pedagogical material. It has been developed by the Open University of Netherlands for eLearning applications. It has demonstate to have a great acceptance yet it has been used and deployed in several runtime systems. Also, a large amount of semantic information related to courses has been modelled with it.

First Post

My name is Jorge L. Herrera, CmpE Student @ University of Puerto Rico ~ Mayaguez Campus. I am currently doing research on Educational Modeling Languages (EML's) under the guidance of Prof. Fernando Vega Riveros.

My research interests are guided towards: GUI development, Human Computer Interaction, Web Apps and Educational Module Development.

Shortly, I will be posting articles describing my research progress and also interesting information describing the latest on EML's.

Note: This blog was created to provide a way of interchanging ideas, comments and feedback between all research team members. It should fascilitate and accelerate the discussion process of issues related to the research topics currently enclosed in the ICOM4998 course.
