To implement an efficient adaptation of content in the network, different variables can be analysed that involve the types of users, the devices used by customers to gain access, the types of access, the state of the network and the current load on the server. The increasing use of hypermedia objects for creating content and the fact that the variables above mentioned are not taken into consideration has led to the problem of inadequate content in many situations. In this paper, a model is suggested for the delivery of hypermedia content that considers these variables. This model, elaborated from an analysis of different research, considers the different points of view observed and has the end objective of defining a System which is Hypermedia Adaptable, Adaptive and Dynamic (SHAAD). This will be the starting point for considering the problem of content adaptation, by means of a totally modular system.
