In this paper the preliminary observations that are result of a first assessment stage of the implementation of the Beta version of the National Repository of Academic, Scientific, Technological and Innovation Information (CTI.MX)/ Mexico are being presented.

This preliminary research is a part of a larger case study that is being analyzed for the doctoral thesis: Open Repositories as Scientific Infrastructure for Research Institutions and Centers of the Education in the Knowledge Society doctorate program of Salamanca's University.

This first analysis is based on empirical observation, on the user's experience and on a preliminary contrast with both the guidelines and standards adopted as international common practice, as well as with the guidelines issued by CONACyT (Mexico's National Council of Science and Technology), since it is the federal government's office in charge of the creation, operation and development of the CTI.MX.
