## 4 Discussion  
New digital representation technologies are a discipline that is continuously evolving. Since their inception, they have had the ability to expand our sensory experiences, especially sight. They can show us spaces that would otherwise not be accessible. With recent advances, we can not only experience other places but also expand the experiences of the places we visit (augmented reality and mixed reality). We can mention digital experiences in digital environments. The protection of heritage and its disclosure is an obligation of today's society. New representation technologies offer us a multitude of possibilities to protect and disseminate our heritage, and now, it is multidisciplinary teams of researchers who are in charge of developing protocols to achieve the maximum dissemination of information. Today's society has an obligation to digitize heritage [37; 59; 60; 61], but it also has the challenge and obligation to disclose it and take advantage of all of the possibilities of the information society. The proposed methodology is divided into two phases. The first phase of data collection and digital twin generation is divided into four steps (developed in activity I), and the second phase, in which the digital twin is incorporated into the metaverse, is divided into six steps (developed in activity VI). Figure 26: Tourist information proposal. Regarding the first phase, we can state that:  
* First of all, as a society, we have an obligation to digitize the world in which we live in order to preserve it as a digital twin for future generations: the present database. * Secondly, from these digital twins, we have the opportunity to recreate lost architectural environments and future digital environments: foundations of the past and the future. * There are many digitization methods, each with advantages and disadvantages [11; 58; 59; 62; 63; 64]. In the present study, a low-cost methodology based on the use of UAVs [65; 23] was chosen, which was outlined and incorporated into the workflow. This scheme is supported by other works and the professional experience of the authors [66; 67]. * For some time now, new representation technologies have allowed us to create resources and content that reflect how our heritage is and could be. These digital twins, both the digital copies of the present and the digital proposals of the past and future [68], give rise to huge databases that have traditionally been used for the development of restoration projects, as in the case study of the Hermitage of the Vaquero, but once the work was completed, it was complex and difficult to use them as a knowledge tool. At this point, our methodology continues. We started from the definition of metaverses as environments in which humans interact and exchange virtual experiences and which are therefore tools for disseminating knowledge. An extensive analysis of the possibilities that researchers have at their disposal today was carried out. In our proposal, an easy alternative is given that guarantees the free diffusion of digital twins. The advantages of this second part of the methodology are the following:  
* These databases are a tool of unquestionable value to change our ways of learning, traveling, disseminating, etc. * We give continuity to previous works by both the authors and other authors [68; 69; 70; 71; 72; 73]. In these works, digital twins were obtained, but the problem of transferring said digital twins to society was not resolved. * In phase 2 of the methodology, in four simple steps, we can upload our virtual twins to a proposed metaverse. * The choice of the metaverse is based on looking for the one that best suits our needs. * The resources obtained in the metaverse are effective tools to use in education. They offer us the opportunity to give our students new digital resources through QR codes or other tools that complement and improve learning by offering resources in augmented reality and virtual reality that can be handled by students.
