| kanzure | Two ways to do compatibility checking between ports- first, geometrical, and second, FEA-like. The first will make sure you don't have a 20 m pipe with a 2 m diameter pipe resting at the port. The second will check to see if the pipes explode, if water leaks, or in electronics, gEDA/SPICES stuff. | 15:52 |
| kanzure | I might be handwaving on the FEA/SPICES though. | 15:52 |
| kanzure | Originally it was just "dimensional analysis" - do the units match up, are the two ports "rated-for" one another. But if you wire something unexpected up to the other geometrical port, the dimensional analysis method will fail ("this pipe knows nothing about electrons"). | 15:54 |

| kanzure3 | ". On a certain abstraction level, a plant consists in modules or components that are interconnected. CAEX allows storage of those modules or components by means of objects. Object oriented concepts as encapsulation, classes, class libraries, instances, instance hierarchies, inheritance, relations, attributes and interfaces are explicitly supported. CAEX bases on XML and is defined as XML schema (xsd file). The original intention of developing CAEX was the industrial lack of a common and established data exchange between process engineering tools and process control engineering tools. However, CAEX can be applied to all types of static object information, e.g. plant topologies, document topologies, product topologies, petri nets, but also for non technical applications like phylogenetic trees." | 21:17 |

| kanzure3 | "Unlike the traditional input–output modelling approach, a model object is acausal (Andersson, 1994; Maffezzoni, Girelli & Lluka, 1996) and, consequently, independent of the context in which it is used: encapsulation actually implies a rigorous standardisation of interfaces, and acausality implies independence of the model equations of the boundary conditions imposed by its connection to other models." | 21:50 |
