The holographic sum rules for GPDs and the appearance of holographic variables in the TMD models are discussed. The relation between GPDs and TMDs in the spirit of Veneziano duality is suggested. The derivation of Burkardt sum rule for Sivers function clarifying its relation to Ji’s sum rules for GPDs is presented. The possibility of its generalization for the case pf separate quark flavours implying the nodes of Sivers functions is discussed.
