Museography is the set of techniques and practices related to the operation of a museum.[1]​ It groups together the techniques of conception and realization of an exhibition, whether temporary or permanent. The physical layout of an exhibition must take into account both the preventive conservation requirements of the objects and the layout and presentation.

Museography must be assumed as a comprehensive and integrative discipline of knowledge whose objective is related to museology. It brings together technical or scientific trades (architecture, restoration of works of art) and artistic trades (scenography, lighting). The museographic elements are, therefore, the display cases, walls that house the works, graphic, audiovisual and interactive pieces, lighting systems and all those resources through which the museological discourse that the exhibition aims to convey is supported and implemented.

Some authors prefer to call it expository techniques, to highlight the importance of considering them in a broader sense than the strictly cultural one. Exhibition techniques fulfill a function and evolve within multiple contexts of cultural and commercial activity.

The term expography, of Anglo-Saxon origin and of little use in Spanish speaking, has a meaning limited to the relationship of the work with the space to fulfill the substratum function of the museum: showing.

The museographic space can be defined as a communication space that expresses, in a sensitive way, the scientific program of the curator&action=edit&redlink=1 "Conservator (museum) (not yet written)") of the museum or of the curator "Curator (art)") of a temporary exhibition. May it be through exposing things or different projects such as paintings, stories from before, exposing so that people can see the works and techniques that were used in the work of the painters or creators; It can also be said as different art in each type of painting, in some it is the fresco technique, watercolor, acrylic, oil, pencil, etc. And the painter takes it to a museum to display it so that people can see it and appreciate his art.

Didactic museography has as its main objective the conception, design and execution of exhibitions based primarily on the principles of didactics, that is, its objective is to provide the objects, artifacts or remains on display with complementary information, contextualization and interpretation tools so that the greatest possible number of visitors can integrate them into their knowledge network.[2]​.
