Achieving a balance between interoperability and security in blockchain systems has led to the development of various integration mechanisms. These include the use of specialized smart contracts to facilitate cross-chain interactions, enabling reliable connections and secure transfers of information and assets. While technical interoperability is effectively addressed at lower layers, achieving semantic interoperability at the application layer remains a significant challenge. This paper proposes a mechanism to address this challenge by leveraging a model-driven approach. Metamodels, models, and transformations are created, and smart contracts are defined abstractly and then semi-automatically generated for specific blockchain platforms. The proposed approach was validated by generating contracts between Ethereum and Hyperledger, enabling semantically compatible transactions. The mechanism was further evaluated using the Technology Acceptance Model with expert participants. This evaluation demonstrated its effectiveness in specifying and transforming contracts and fostering semantic interoperability across blockchains.

Actually the Software Industry in Colombia has been accumulating experience and growing. However, there has been a shortage of competent professionals for this sector. In this sense, Universities need to train this type of professionals who can quickly be linked to work. Starting from this challenge and understanding the new training demands in the world, this article presents how the first didactic transformation of a learning factory for the Software Engineering area is developed. Methodologically, a model is proposed for the representation of well-formed competencies and learning outcomes. In addition, a protocol for the development of the first didactic transformation is presented. The results show the status of the main companies in the Software Industry in Colombia. Furthermore, the competencies and learning outcomes for the services associated with the category are presented: software construction, support, and maintenance. The main contribution of this work was to propose a model to represent well-formed competencies and learning outcomes. Moreover, the proposal is used in the development of the first didactic transformation of a learning factory for the Software Engineering area.

This paper presents a community of practice with the aim of potentiate students' skills for developing applications for mobile devises. The stages of this proposal are approaching, diagnostic, preparation, development, and monitoring. The results obtained in the monitoring stage demonstrate that the community of practice impacts positively for potentiating the knowledge, skills and abilities of its members. This allows members to increase the possibility to be hired in a labour market, which is in constant growth.
