Oct 10 at 10:30 comment added Bill Bradley Dear Lukas, this is more for general context than helping with your specific question, but two comments: (1) in terms of "non-constant size" random variables, you may find it interesting to explore non-parametric statistics, and (2) as specific examples where people handle variable-sized clusters of objects, consider checking out the "Chinese Restaurant Process" and "Dirichlet Process Mixture Models". (Of course, these are harder problems, because you're also trying to infer the clusters, but they may have some relevance towards whatever motivates this question.)

Oct 8 at 16:53 comment added Iosif Pinelis I cannot parse your definition of $D(X,K)$.
Oct 8 at 16:32 comment added user76284 This might be a better way to formulate your question: Let $\mathcal{K}$ be the set of possible keys and $\mathcal{V}$ be the set of possible values. A dictionary is simply an element of $\mathcal{D} = \bigcup_{\mathcal{S} \in \mathcal{P}_\text{finite}(\mathcal{K})} (\mathcal{S} \to \mathcal{V})$, that is, a function from a finite set of keys to values. For any given dictionary $f$, $\operatorname{dom} f$ is its set of keys, and $\operatorname{im} f$ is its set of values.
