“…Additionally, Bloqqi has block type inheritance and redeclaration inspired by mechanisms in Modelica (Modelica 2012). Bloqqi furthermore supports connection interception, where a connection in a supertype can be intercepted and rerouted through a block subnet (Fors and Hedin 2014). 4 Similar to Modelica, Bloqqi has both a textual syntax that covers the complete language and a visual syntax that covers block configuration.…”

“…A diagram subtype can specialize the behaviour of its supertype using connection interception (Fors and Hedin 2014). A connection interception allows a connection defined in a supertype to be intercepted, that is, to reroute it to go via another block or network of blocks.…”

“…In earlier work (Fors and Hedin 2014), we introduced the interception construct, and then used multiple inheritance to combine features into a desired variant. While this is a possible way to modularize and reuse components, it has several drawbacks.…”

“…The language mechanisms proposed in this paper are based on diagram inheritance: a subtype can extend a supertype diagram with additional connections and blocks, and can also specialize the behavior in the supertype, in analogy to method overriding in object-oriented languages. In particular, specialization is supported by connection interception (Fors and Hedin 2014) and block redeclaration (Modelica 2012). Connection interception allows the subtype to intercept connections defined in the supertype, that is, to reroute the connection to go via another block or subnet.…”

Automation programming is typically done using blocks and dataflow connections, in diagram languages that support userdefined block types. Often, these types are intended to be instantiated and connected to other blocks in common patterns, corresponding to anticipated variability. We present the new language mechanisms of wirings and recommendations that allow these intentions to be encoded as features in libraries. A wiring describes how a given block is typically connected to other blocks, and a recommendation describes where such a wiring is typically applied as a feature. This allows feature-based wizards to be generated for user-defined libraries, making it easy to construct applications that make use of the encoded patterns.

“…In a domain where there are few theories or frameworks that purport to be predictive and constructive, the physics of notations presents a strong contribution. Examples of applying the framework can be found for visualisations in: enterprise systems modelling [17], business process modelling, requirements engineering [9,10] and dataflow diagrams [6,8]. In general, these works apply the physics of notations to existing visualisations with a view to identifying weaknesses within them.…”

This paper presents a critical reflection upon the concept of 'physics of notations' proposed by Moody. This is based upon the post hoc application of the concept in the analysis of a visualisation tool developed for a common place mathematics tool. Although this is not the intended design and development approach presumed or preferred by the physics of notations, there are benefits to analysing an extant visualisation. In particular, our analysis benefits from the visualisation having been developed and refined employing graphic design professionals and extensive formative user feedback. Hence the rationale for specific visualisation features is to some extent traceable. This reflective analysis shines a light on features of both the visualisation and domain visualised, illustrating that it could have been analysed more thoroughly at design time. However the same analyse raises a variety of interesting questions about the viability of scoping practical visualisation design in the framework proposed by the physics of notations.
