+<summary>Abstract</summary>
+<blockquote>
+<p>Declarative behavioural modelling is a powerful modelling paradigm
+that enables users to model system functionality abstractly and
+formally. An abstract model is a concise and compact representation
+of key characteristics of a system, and enables the stakeholders to
+reason about the correctness of the system in the early stages of
+development.</p>
+
+<p>There are many different declarative languages and they have
+greatly varying constructs for representing a transition system, and
+they sometimes differ in rather subtle ways. In this thesis, we
+compare seven formal declarative modelling languages B, Event-B,
+Alloy, Dash, TLA<sup>+</sup>, PlusCal, and AsmetaL on several
+criteria. We classify these criteria under three main categories:
+structuring transition systems (control modelling), data descriptions
+in transition systems (data modelling), and modularity aspects of
+modelling. We developed this comparison by completing a set of case
+studies across the data- vs. control-oriented spectrum in all of the
+above languages.</p>
+
+<p>Structurally, a transition system is comprised of a snapshot
+declaration and snapshot space, initialization, and a transition
+relation, which is potentially composed of individual transitions.
+We meticulously outline the differences between the languages with
+respect to how the modeller would express each of the above components
+of a transition system in each language, and include discussions
+regarding stuttering and inconsistencies in the transition relation.
+Data-related aspects of a formal model include use of basic and
+composite datatypes, well-formedness and typechecking, and separation
+of name spaces with respect to global and local variables. Modularity
+criteria includes subtransition systems and data decomposition.
+We employ a series of small and concise exemplars we have devised to
+highlight these differences in each language. To help modellers
+answer the important question of which declarative modelling language
+may be most suited for modelling their system, we present
+recommendations based on our observations about the differentiating
+characteristics of each of these languages.</p>
