« Ranking » is a Wikibase feature to deal with this. If one of the statement is ranked « preferred », typically the one valid at present time, then it will be the only one present in a typical query result or in an infobox extraction.

>All=contains not only the Truthy ones, but also the ones with qualifiers

imho:  Sometimes Qualifiers is very important for multiple values  (   like "Start time","End time","point in time", ... )

for example:   Russia https://www.wikidata.org/wiki/Q159  :  Russia - P38:"currency"

has 2 "statements" both with qualifiers:

* Russian ruble -  ( start time: 1992 )

* Soviet ruble  - (end time: September 1993 )

My Question:
in this case - what is the "Truthy=simple" result for   Russia-P38:"currency" ?

Truthy=simple, direct, only Subject-Predicate-Object structure

For example: wd:Q76127 wdt:P26 wd:Q468519 (= Sukarno hasSpouse Fatmawati)

All=contains not only the Truthy ones, but also the ones with qualifiers (= how long was the marriage? when did the marriage happen?), references (sources to support the claim), and preferences (in case of multiple values, one might be preferred -- think of multiple birth dates of some people).

Can somebody please explain (in simple terms) what's the difference between "all" and "truthy" RDF dumps? I've read the explanation available on the wiki [1] but I still don't get it.
If I'm just a user of the data, because I want to retrieve information about a particular item and link items with other graphs... what am I missing/leaving-out by using "truthy" instead of "all"?
A practical example would be appreciated since it will clarify things, I suppose.
