  In this work we construct global resolutions for general coherent equivariant
sheaves over toric varieties. For this, we use the framework of sheaves over
posets. We develop a notion of gluing of posets and of sheaves over posets,
which we apply to construct global resolutions for equivariant sheaves. Our
constructions give a natural correspondence between resolutions for reflexive
equivariant sheaves and free resolutions of vector space arrangements.
