In the e-learning field, distance learning is promoted through educational platforms, teachers use it to transmit knowledge and to monitor and evaluate the work and progress of students. The platforms do not offer personalized services and therefore do not take into account aspects of customization such as interest, motivation and their reciprocal collaboration.

Our work aims to provide educators with an easy way to create and administer virtual spaces to create an online collaborative educational content. This tool will allow generating and editing educational content that provides better adaptation of courses and activities of a teaching and learning style. Otherwise, the social constructivism approach is to focus activities on learners and thus facilitate synchronous and asynchronous collaboration between them, so it is necessary to find a method that models all types of activities.

To achieve this goal, we will propose in this study a collaborative meta-model for a system that is designed to meet the needs of educational projects that require online collaboration, and teachers' needs in terms of generating a collaborative educational content.

Currently our work is a step toward modeling a meta-model of collaborative online education compatible with the IMS-LD (Instructional Management Systems- Learning Design), which will lead us to adopt the MDA approach (Model Driven Architecture) defined by the OMG (Object Management Group) which is based on four stages of implementation:
First, the development of a free independent computer model (CIM: Computer Independent Model) and its manual transformation into a model in a particular technological context (PIM: Platform Independent Model), then its automatic transformation into a model associated with achieving the targeted platform (PSM: platform Specific Model) model to be refined and ultimately realized in a target platform.

To determine the transformation, it is necessary to have processing tools. These are based on the languages of transformation to respect the QVT (Query View Transformation) standard proposed by the OMG. There is an offer of free tools (ATL, MTF, MTL, QVTP, etc.) and commercial (eg MIA). We will use ATL (Atlas Transformation Language) from the offer of free tools, to the extent that one ATL provides consistency with OMG / MDA / MOF (Meta Object Facility) / QVT.

After modeling the collaborative meta-model, we will be able to create collaborative learning activities compatible with IMS-LD.
