The process that results in the patterns of cell differentiation that will arise in an embryo. The specification of the characteristic structures of trunk segments, following establishment of segment boundaries. In Drosophila, the trunk segments include thoracic segments and abdominal segments A1 to A8. Identity is considered to be the aggregate of characteristics by which a structure is recognized. The regionalization process that divides an organism or part of an organism into a series of semi-repetitive parts, or segments, often arranged along a longitudinal axis. Partitioning of the blastoderm embryo into trunk segmental units. In Drosophila, the trunk segments include thoracic segments and abdominal segments A1 to A8. The hierarchical steps resulting in the progressive subdivision of the anterior/posterior axis of the embryo. The pattern specification process by which an axis or axes is subdivided in space to define an area or volume in which specific patterns of cell differentiation will take place or in which cells interpret a specific environment.
