  Assuming the existence of the dS/CFT correspondence, we construct local
scalar fields with $m^2>\left( \frac{d}{2} \right)^2$ in de Sitter space by
smearing over conformal field theory operators on the future/past boundary. To
maintain bulk micro-causality and recover the bulk Wightman function in the
Euclidean vacuum, the smearing prescription must involve two sets of
single--trace operators with dimensions $\Delta$ and $d-\Delta$. Thus the local
operator prescription in de Sitter space differs from the analytic continuation
from the prescription in anti--de Sitter space. Pushing a local operator in the
global patch to future/past infinity is shown to lead to an operator relation
between single--trace operators in conformal field theories at
$\mathcal{I}^\pm$, which can be interpreted as a basis transformation, also
identified as the relation between an operator in CFT and its shadow operator.
Construction of spin$-s$ gauge field operators is discussed, it is shown that
the construction of higher spin gauge fields in de Sitter space is equivalent
to constructing scalar fields with specific values of mass parameter
$m^2<\left( \frac{d}{2} \right)^2$. An acausal higher spin bulk operator which
matches onto boundary higher spin current is constructed. Implementation of the
scalar operator constructions in AdS and dS with embedding formalism is briefly
described.
