  This white paper describes a proposed article that will aim to provide a
thorough study of the evolution of the typical paradigm of wireless
localization (WL), which is based on a single point model of each target,
towards wireless rigid body localization (W-RBL). We also look beyond the
concept of RBL itself, whereby each target is modeled as an independent
multi-point three-dimensional (3D), with shape enforced via a set of
conformation constraints, as a step towards a more general approach we refer to
as soft-connected RBL, whereby an ensemble of several objects embedded in a
given environment, is modeled as a set of soft-connected 3D objects, with rigid
and soft conformation constraints enforced within each object and among them,
respectively. A first intended contribution of the full version of this article
is a compact but comprehensive survey on mechanisms to evolve WL algorithms in
W-RBL schemes, considering their peculiarities in terms of the type of
information, mathematical approach, and features the build on or offer. A
subsequent contribution is a discussion of mechanisms to extend W-RBL
techniques to soft-connected rigid body localization (SCW-RBL) algorithms.
