A Digital Twin is a virtual representation that embodies an asset of any type {[}IOSB18{]}. In that sense a DT is compared to the Asset Administration Shell (AAS). Smart Manufacturing is a real thing of a factory represented by its structure and behavior of inter-connected things that generate real-time data {[}IOSB18{]}. By combining Smart Manufacturing processes with a Digital Twin it is intended to validate operations of a production systems in real-time. In general the properties of inter-operating things respectively systems, and especially the properties of energy transportation between systems are considered to be the 'Prove of Concepts' (PoC) of semantics. When The Information Technology (IT) that processes data and up to some extend information, is compared to the technology that enables communication ...

For a broad definition of QoS we refer to the ISO's Reference Model for Open Distributed Processing (ISO/IEC IS 10746-2): `The notion of QoS is a system or object property, and consists of a set of quality requirements on

This paper reports on the experience gained in developing an algebraic specification of a transport service. A pragmatic guideline for the development of a specification based on an abstract model of the transport service is demonstrated and the relation of the algebraic specification to other specification concepts used in the field is discussed. We show especially how properties can be derived from the specification and expressed in terms of OSI concepts. Finally benefits and limitations of the algebraic specification with respect to the general requirements for specifications in the field of Open Systems Interconnections are reviewed.

The enhancements defined modular concepts for LOTOS (chapter 22) and introduced new features for data specifications. This chapter will concentrate on the proposed changes concerning data specifications. The objective of the chapter is to introduce to the new concepts and to show their application by examples. For clarity we will use the term Modular LOTOS to refer to the new language proposals in distinction to ISO LOTOS, as it is defined in the ISO Standard 8807.

These points represent specialized flow behaviour to show the causality chain of QoS control operations to be instantiated during binding. Elements of the binding procedure and the points of QoS concerns are represented by a suggested modelling notation extending TINA's ODL (Object Definition Language). A QoS-extended binding model has been elaborated by augmenting the binding concepts of the ODP (Open Distributed Processing) framework with the QoS points of concern, which comprise the declaration of continuous stream behaviour at end-points, observations, conformance, control, steering and negotiation. The suitability of the extended binding model has been validated by several examples, e.g. the specification of a video system which is bound by an ATM network. The QoS binding model provides a way of mapping QoS from an application level to the component and networking levels. The application level is where the objects of the application community are grouped and their interfaces are contracted. The negotiated QoS characteristics are mapped to the component level by the binding process which instantiates components accordingly. Hence, QoS mapping is part of the extended binding model. For example, the potential QoS of an ATM network, as it might be required by a video user, must be mapped to the observation and conformance points at the interface between the end user and the network access point

We had 22 submissions, with a variety of strengths. With careful deliberation and vigorous debate by the program committee of this track, we have selected six papers addressing middleware issues in the power grid, web service robustness, multimodal multiparty collaboration, and infrastructure clouds.

The four parts provide the concepts and rules of distributed processing to ensure openness between interacting distributed application components. Openness is a combination of characteristics, i.e. scalability, accessibility, heterogeneity, autonomy and distribution. The RM-ODP introduces the concept of viewpoint to describe a system from a particular set of concerns, and hence to deal with the complexity of distributed systems. .

Industrieanlagen haben eine eigene inhärente Struktur, die in dem Referenz-Architekturmodell RAMI4.0 [ZVEI15], erstellt von einem Verbandskonsortium, geführt von ZVEI, skizziert ist. Diese Struktur fällt ins Gewicht, wenn ein Security-by-Design-Ansatz für verbundene, verteilte Industrieanlagen gewählt wird. Unter Sicherheit für IAC-Systemen werden hierbei im weitesten Sinne Systemeigenschaften und -fähigkeiten verstanden, die im sog. 'Pentagon of Trust' [JdM16] genannt werden, nämlich Vertrauen in vernetzte Produktionsanlagen und -geräten, Geheimhaltung von Fabrikationsdatensätzen, prüfbare Beachtung von Regulierungen und Gesetzen, Garantierung der Funktionalität von Produktionsanlagen und die einsichtige Anwendbarkeit von Anlagen und Geräten, was in ähnlicher Weise auch für vernetzte Geräte im sog. Internetz der Dinge (IoT -Internet of Things) gilt. Der 2te GI/ACM I4.0 WS strukturiert sich in die Handlungsgebiete: Architektur und Frameworks, Industrielle Erfahrung -Best Practice, Formalisierung und IACS Semantiken.

Hence in order to achieve a human AI, new semantic categories of standards must be written enabling stakeholders to implement a responsible AI. Communication however generates lots of unstructured data sets to be classified and structured into data types. AI-based algorithms are suitable to derive - from data sets and data types - more sophisticated and implicitly given information that can further be enriched to knowledge about autonomous communicating processes or even autonomous behaving humans. The knowledge gained from applying data enrichment algorithms in turn may be used for reasoning and prediction purposes, thus improving applications a lot. The aim of this project is to find a common unified tool able to handle big data flows and types that allows the recognition of hidden information from both data flows and data types. The hidden information is sometimes also called meta-data, thus being implicitly existing but by tools becoming explicitly seen.
