Such a statement may or may not reflect what that %%party|party%% holds or %%knows|knowledge%% to be true - %%parties|party%% may lie.The simplest kind of assertions come in the form ('subject', 'predicate', 'object'). For example, the triple ('John', 'is married to', 'Jill') says 'John is married to Jill'. Note that 'subject', 'predicate' and 'object' are all %%identifiers|identifier%% or other representations of the %%knowledge|knowledge%% to the assertion's %%owner|owner%%, and may not be dereferenceable in other contexts.### PurposeThe ability to distinguish between assertions and non-assertions, and particularly to know its %%owner|owner%%, is prerequisite for properly interpreting it (to establish its meaning), determining its trustworthiness, deciding whether or not to (re)act, and if so, what that reaction would be.### CriterionAn **Assertion** is any declaration/statement that is made by one specific %%party|party%%.
### Notes- Assertions may be ambiguous (multi-interpretable), which may result in misundertandings. The authoritative meaning of an %%assertion|assertion%% is determined by (the %%semantics|semantics%% that was applied by) the %%party|party%% that has uttered/authored it.- Assertions may or may not be true. That is not only because 'truth' is subjective (every %%party|party%% may decide whether or not something is true), but also because the %%party|party%% that uttered/authored the %%assertion|assertion%% cannot substantiate the assertion, or lie outright.
