Well... it depends on what you want to do. i had done some tests with
search() and pulldata().
If you want to reload some data (like, household address, the names of each
household members, their genres... the variables which can be used to
identify the household or its members)* but you dont want to modify that
data in the follow up* you can try with this:
https://opendatakit.org/help/form-design/data-preloading/
If you want to preload some data to modify it, you can't do it with the
default ODK. SurveyCTO maybe can do it.
The scenario that could work is.... you survey for the first time, get the
address, geopoint, emmm the name of each household member (in a repeat),
and "sickness" variables for each member (in the same repeat, or in a
different one)
Then, in the follow up visit, you preload the address, geopoint, the name
of each household member, and enter new values for the sickness variables.
(maybe you should use a different form for firsts and followups)
the problem is... the "pulldata()" function preloads data from a CSV file,
but collect calculates and pulls data on every damn input, even *after *you
change the value of the preloaded input. so, you can use pulldata() for the
inputsrelated to the identification of the household or its members,
because they don't change with time (so get it fine on first visit!); but
you can't use it to review the old answer and change it on the same input.
maybe you can use it for all the inputs... you can create two versions of
your form. one for first visits, and one for followups. the followup form
should be almost the same of the firstvisits, but each question shall be
three inputs... "old value (read only)"; "do you wanna change it?" "enter
new value". you should have some inputs designed specifically for the
follow ups, in case one of the members does not live in the household when
you survey in the follow up (he lives somewhere else, he died, he
travelled)... or if there is a new houselhold member (he was born recently,
he comes from somewhere else, and will live here).
(sorry bout mah broken engrish)
