Classes of gismu

Many gismu are related to each other in the sense that they address representatives of an open class: they all belong to a set, and there may be additional members of the set not yet known. We will consider open classes which are exhaustively enumerated from the baseline, but open to experimental gismu; this allows us to confidently categorize the baseline while allowing extension from the community.

Classes of n-ary relations are slightly more complex, and instead of a parametric presentation, we will use a schematic presentation. A class schema is a diagram textually represented as multiple lines of the following form:

broda*k*: brode*l*

Asserting that every element of the k-th place of {broda} is an element of the l-th place of {brode}:

ro da poi fa*k* broda zo'u: fa*l* brode

Or the following form:

broda*k*: *x*s

Asserting that there is an open class x which contains every element of the k-th place of {broda}. Note that this second form is not formalizable, but semantic; it indicates when an open class is primitive with regard to Lojban's semantic space.
