Extensible executable models in the development of an ePortfolio

The ePortfolio have become a valuable tool applied in multiple contexts such as education and employment, with many of purposes and audiences. In the educational context the ePortfolios help to guide, motivate and track training processes and facilitate communication between participating agents. The IMS ePortfolio specification intends to standardize the structure of ePortfolios to enable the exchange and interoperability between applications that use them. This article proposes the application of extensible executable models to model the domain of features or attribute-value properties, and apply it to building a student ePortfolio. The context of use of the portfolio is defined by the projects Cumbia LD and cupi2, and takes into consideration the IMS ePortfolio specification for the design.
