Concepts:

We have the following data types:

String: represent text and are sentences or words between double quotes "
Boolean: true and false represent yes and no
Number: 1, 2 etc
Decimal numbers: 1.0, 2.322 etc
Context value: #sessionid, #tag that represents external values that can be replaced at runtime
Variable: $this_is_a_variable, $this which is a wildcart at which we assign a value if exists
Array: ["Hello", 1, 1.0], which rapresents a list of values, strings or numbers

And the following statements:

working memory element
has attribute
is a entity
is not an entity
has no attribute
filter
function
