A method of facilitating transformation of survey data from being in at
least one foreign format used by a survey-tool to being in a desired
format may include: receiving instances of foreign data from
survey-tools, the foreign data being in foreign format used by the
survey-tools, respectively; and appending, to the instances of foreign
data, service-keys to identify the service tools which gathered the
foreign data, respectively, to produce a data block that includes
key-and-foreign-data pairs. Another such method may include: receiving
such a data block; culling from the block key-and-foreign-data pairs; and
operating upon the pairs to transform respective chunks of foreign data
from being in respective foreign formats into being in corresponding
desired formats according to corresponding service-keys, respectively.
