Formation and/or maintenance of a lineage boundary between dorsal and ventral compartments that cells cannot cross, thus separating the populations of cells in each compartment. Any developmental process that results in the creation of defined areas or spaces within an organism to which cells respond and eventually are instructed to differentiate. The establishment, maintenance and elaboration of the dorsal/ventral axis of the imaginal disc. Imaginal disks are masses of hypodermic cells, carried by the larvae of some insects after leaving the egg, from which masses the wings and legs of the adult are subsequently formed. The regionalization process by which the areas along the dorsal/ventral axis are established that will lead to differences in cell differentiation. The dorsal/ventral axis is defined by a line that runs orthogonal to both the anterior/posterior and left/right axes. The dorsal end is defined by the upper or back side of an organism. The ventral end is defined by the lower or front side of an organism. Formation and/or maintenance of a lineage boundary between compartments in an imaginal disc that cells cannot cross, thus separating the populations of cells in each compartment. The regionalization process that results in defined areas of the imaginal disc that will undergo specific cell differentaiton. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult appendages (legs, antennae, wings, etc.) during metamorphosis from larval to adult form.
