abstract = {Factories have to adapt permanently to changing situations in order to stay
competitive. Premise to achieve this objective is up-to-date information on all
levels of a factory and during the product life cycle, so that men and machine
can optimize their activities according to their tasks. One approach to
implement this economically is the massive application of sensors and
information and communication technologies (ICT) leading to a Smart Factory.
This process and related applications are summarized under the term of the
forth industrial revolution (Industrie 4.0). It demands a flexible and
easy-to-use integration of assets on the shop floor with ICT systems. The
contribution of this paper is the MIALinx system that enables all these steps.
The steps range from the integration to the sensing and analyzing of the sensor
data to the execution of required actions. Furthermore, MIALinx provides an
abstract rule based approach for users to model the behavior of the system. The
presented system is based on concepts and technologies of the Internet of
Things and service-oriented middleware. The main users targeted with our system
are small and medium-sized enterprises that do not have the expertise or the
investment possibilities to invest in completely new Industrie 4.0 systems but
rather use their existing production assets and enrich them to achieve
Industrie 4.0 capability.},

abstract = {Recent developments and steadily declining prices in ICT enable an economic
application of advanced digital tools in wide areas of manufacturing. Solutions
based on concepts and technologies of the Internet of Thingsť or Cyber Physical
Systems can be used to implement monitoring as well as self-organization of
production, maintenance or logistics processes. However, integration of new
digital tools in existing heterogeneous manufacturing IT systems and
integration of machines and devices into manufacturing environments is an
expensive and tedious task. Therefore, integration issues on IT and
manufacturing level significantly prevent agile manufacturing. Especially small
and medium-sized enterprises do not have the expertise or the investment
possibilities to realize such an integration. To tackle this issue, we present
the approach of the Manufacturing Integration Assistant - MIALinx. The
objective is to develop and implement a lightweight and easy-to-use integration
solution for small and medium-sized enterprises based on recent web automation
technologies. MIALinx aims to simplify the integration using simple
programmable, flexible and reusable IF-THEN rules that connect occurring
situations in manufacturing, such as a machine break down, with corresponding
actions, e.g., an automatic maintenance order generation. For this purpose,
MIALinx connects sensors and actuators based on defined rules whereas the rule
set is defined in a domain-specific, easy-to-use manner to enable rule modeling
by domain experts. Through the definition of rule sets, the workers{\^a}€™
knowledge can be also externalized. Using manufacturing-approved cloud
computing technologies, we enable robustness, security, and a low-effort,
low-cost integration of MIALinx into existing manufacturing environments to
provide advanced digital tools also for small and medium-sized enterprises.},

modern information systems results in several challenges for modeling,

themselves to changing situations in dynamic environments. The properties of
the workflow technology, such as its recovery features, makes this technology
suitable to be leveraged in such environments. However, the realization of
situation-aware mechanisms that dynamically adapt process executions to
changing situations is not trivial and error prone, since workflow modelers
cannot reflect all possibly occurring situations in complex environments in
their workflow models. In this paper, we present a method and concepts to
enable modelers to create traditional, situation-independent workflow models
that are automatically transformed into situation-aware workflow models that
cope with dynamic contextual situations. Our work builds upon the usage of
workflow fragments, which are dynamically selected during runtime to cope with
prevailing situations retrieved from low-level context sensor data. We validate
the practical feasibility of our work by a prototypical implementation of a
Situation-aware Workflow Management System (SaWMS) that supports the presented
concepts.},

integration of these two areas by providing a cloud-based situation recognition
service – SitRS. This service can be used to integrate real world objects – the
things – into the internet by deriving their situational state based on
sensors. This enables context-aware applications to detect events in a smart
environment. SitRS is a basic service enabling a generic and easy
implementation of Smart* applications such as SmartFactorys, SmartCities,
SmartHomes. This paper introduces an approach containing a method and a system
architecture for the realization of such a service. The core steps of the
method are: (i) registration of the sensors, (ii) modeling of the situation,
and (iii) execution of the situation recognition. Furthermore, a prototypical
implementation of SitRS is presented and evaluated via runtime measurements.},

abstract = {Today, a multitude of highly-connected applications and information systems
hold, consume and produce huge amounts of heterogeneous data. The overall
amount of data is even expected to dramatically increase in the future. In
order to conduct, e.g., data analysis, visualizations or other value-adding
scenarios, it is necessary to integrate specific, relevant parts of data into a
common source. Due to oftentimes changing environments and dynamic requests,
this integration has to support ad-hoc and flexible data processing
capabilities. Furthermore, an iterative and explorative trial-and-error
integration based on different data sources has to be possible. To cope with
these requirements, several data mashup platforms have been developed in the
past. However, existing solutions are mostly non-extensible, monolithic systems
or applications with many limitations regarding the mentioned requirements. In
this paper, we introduce an approach that copes with these issues (i) by the
introduction of patterns to enable decoupling from implementation details, (ii)
by a cloud-ready approach to enable availability and scalability, and (iii) by
a high degree of flexibility and extensibility that enables the integration of
heterogeneous data as well as dynamic (un-)tethering of data sources. We
evaluate our approach using runtime measurements of our prototypical
implementation.},

abstract = {eHealth gains more and more interest since a lot of end-user devices which
support health data capturing are available. The captured data has to be
managed and securely stored, in order to access it from different devices and
to share it with other users such as physicians. The aim of the German-Greek
research project ECHO is to support the treatment of patients, who suffer from
Chronic Obstructive Pulmonary Disease (COPD), a chronic respiratory disease.
Usually the patients need to be examined by their physicians on a regular basis
due to their chronic condition. Since this is very time consuming and
expensive, we develop an eHealth system which allows the physician to monitor
patients conditions remotely, e.g., via smart phones. Therefore, a secure data
processing and sharing eHealth platform is required. In this paper we introduce
a health data model and a corresponding platform-architecture for the
management and analysis of the data provided by the patients. Furthermore, we
show how the security of the data is ensured and we explain how the platform
can be hosted in a cloud-based environment using the OASIS standard TOSCA,
which enables a self-contained and portable description and management of
cloud-services.},

abstract = {Workflows are an established IT concept to achieve business goals in a reliable
and robust manner. However, the dynamic nature of modern information systems,
the upcoming Industry 4.0, and the Internet of Things increase the complexity
of modeling robust workflows significantly as various kinds of situations, such
as the failure of a production system, have to be considered explicitly.
Consequently, modeling workflows in a situation-aware manner is a complex
challenge that quickly results in big unmanageable workflow models. To overcome
these issues, we present an approach that allows workflows to become
situation-aware to automatically adapt their behavior according to the
situation they are in. The approach is based on aggregated context information,
which has been an important research topic in the last decade to capture
information about an environment. We introduce a system that derives high-level
situations from lower-level context and sensor information. A situation can be
used by different situation-aware workflows to adapt to the current situation
in their execution environment. SitOPT enables the detection of situations
using different situation-recognition systems, exchange of information about
detected situations, optimization of the situation recognition, and runtime
adaption and optimization of situationaware workflows based on the recognized
situations.},

help to reduce the onboarding costs for new customers as well as the financial
impact of managing Cloud Services by automating these previously manual tasks.
With the widespread use of such systems, the adoption of a common standard for
describing Cloud applications will provide a crucial advantage by enabling
reusable and portable applications. TOSCA, a newly published standard by OASIS
with broad industry participation provides this opportunity. Besides the
technical requirements of running and managing applications in the cloud,
non-functional requirements, like cost, security, and environmental issues, are
of special importance when moving towards the automated provisioning and

non-functional requirements are defined in TOSCA using policies. We propose a
mechanism for automatic processing of these formal policy definitions in a
TOSCA runtime environment that we have developed based on the proposed
architecture of the TOSCA primer. In order to evaluate our approach, we present
prototypical implementations of security policies for encrypting databases and
for limiting the geographical location of the Cloud servers. We demonstrate how
our runtime environment is ensuring these policies and show how they affect the

abstract = {Using spatial models as a shared common basis of information about the
environment for different kinds of context- aware systems has been a heavily
researched topic in the last years. Thereby the research focused on how to
create, to update, and to merge spatial models so as to enable highly dynamic,
consistent and coherent spatial models at large scale. In this paper however,
we want to concentrate on how context-aware applications could use this
information so as to adapt their behavior according to the situation they are
in. The main idea is to provide the spatial model infrastructure with a
situation recognition component based on generic situation templates. A
situation template is - as part of a much larger situation template library -
an abstract, machine- readable description of a certain basic situation type,
which could be used by different applications to evaluate their situation. In
this paper, different theoretical and practical issues - technical, ethical and
philosophical ones - are discussed important for understanding and developing
situation dependent systems based on situation templates. A basic system design
is presented which allows for the reasoning with uncertain data using an
improved version of a learning algorithm for the automatic adaption of
situation templates. Finally, for supporting the development of adaptive
applications, we present a new situation-aware adaptation concept based on
workflows.},

abstract = {In factories many processes are executed in parallel. The manufacturing
processes are managed by Manufacturing Execution Systems. In the case of
machine failures these systems provide only rudimentary or no support to the
workers or shop-floor managers. As a consequence the failures have to be fixed
as fast as possible for being able to continue manufacturing processes. For
such cases context-aware workflows can be used to support the workers and to
coordinate the work that has to be done for repairing purposes. In the Nexus
Project we introduced the concept of context-aware workflows and context
integration processes to be able to implement all kinds of processes going on
in a smart environment. As a case study we modeled a failure management process
as a workflow and executed it in a factory. Furthermore, we show the concepts
behind this kind of workflows: the context integration processes and the
context-aware human tasks. Finally, end user applications for the interaction
of the workers with the workflow are presented. For that we developed an
application concept providing a mobile solution for workers and a web-based
solution for an office environment. The main contribution of this paper is to
show how to implement such a failure management process as a context-aware
workflow.},

problem. In this paper we describe these difficulties which result from the
combination of very distinct areas. On the one hand, applications from area of
measurement engineering manage sensors that capture data and annotate the data
with technical meta data. On the other hand, context-aware workflows from the
BPM area place high level requirements for the quality of context data that is
derived from the sensor data. Between those two areas exists a gap that has to
be closed by a context management and mediation system, supporting the handling
of Quality of Context (QoC). To achieve this the paper presents an QoC aware
architecture based on an extension of the existing Nexus Platform and a first
approach for matching the workflow requirements with the sensor annotations.},

show several use cases where such value passing behavior has drawbacks. To
address this challenge we introduce the concept of pointers in SOA. Pointers
allow services to pass their data by reference which is a fundamental advantage
for Web Service communication. Furthermore we show an extension of BPEL that
introduces reference variables as new type of data containers in workflows. In
addition, for the management of pointers we present the Reference Resolution

service requesters and service providers to enable late binding of services at
deployment time or even dynamic binding of services at runtime. This is
important in enterprise settings, where different services that implement
business functions in critical business processes are dynamically chosen based
on availability or price. The same problem also applies to dynamic Grid
environments where resources need to be dynamically chosen based on
availability and other non-functional properties. The WS-Policy framework
describes how policies for both providers and requesters are specified to allow
the selection of services based on these policies. Existing approaches, using
WS-Policy, have drawbacks by placing the burden of the service selection
partially on the client. In this paper we present an approach to extend an
enterprise service bus that allows service clients to submit policies the
service provider needs to comply with directly in the message that triggers the
service invocation. We show how these policies are evaluated in the bus and how
policies are defined for not only stateless services, but also stateful
resources.},

pattern generally solves the problem of integrating different complex systems
that provide functional similar services with non-fitting interfaces into
workflows. The pattern allows that workflows use simple domain specific
interfaces that are the same for any of these systems and by that allow the
exchange of underlying systems without changing the workflows. This is
accomplished by reducing the interface complexity of the systems via a
hierarchical Web Service stack that reaches from the lowest technical
granularity needed by IT experts to the domain specific granularity needed by
the domain experts. Furthermore the paper presents a concrete realization of
the pattern for integrating different context provisioning systems into

abstract = {Context-aware applications adapt their behavior based on changes of the
physical world, which is often obtained with a huge amount of sensors. Thus,
the development of such applications is cumbersome, in particular the
implementation of their often complex control flow. To ease the development of
context-aware applications we present the concept of context-aware workflows.
Thereafter we present an implementation of these concepts based on a standard
workflow language. Context-aware workflows are not only interesting for the
development of context-aware applications, but also enable workflow technology
to be applied in new domains that are process oriented and yet not supported by
workflow systems like production processes in the manufacturing industry. The
concept of context-aware workflows is a first approach that enables modeling
and execution of technical production processes with workflow systems normally
used for business processes.},

abstract = {A central task in the development of context-aware applications is the modeling

NexusEditor, which can ease this task by providing a graphical user interface
to design schemas for spatial and technical context models, interactively
create queries, send them to a server and visualize the results. One main
contribution is to show how schema awareness can improve such a tool: The
NexusEditor dynamically parses the underlying data model and provides
additional syntactic checks, semantic checks, and short-cuts based on the
schema information. Furthermore, the tool helps to design new schema
definitions based on the existing ones, which is crucial for an iterative and
user-centric development of context-aware applications. Finally, it provides
interfaces to existing information spaces and visualization tools for spatial
data like GoogleEarth.},

Context-aware applications adapt their behavior according to the current
situation. In this paper we present a layered model to separate different tasks
and concerns in designing data models for context-aware applications. The
layers are discussed along the Nexus approach, which is designed to support
large-scale, mobile applications by federated context models. Furthermore,
related approaches are described and compared.
Zusammenfassung
Kontextbezogene Anwendungen adaptieren ihr Verhalten aufgrund von Situationen.
Dieser Beitrag pr{\"a}sentiert ein Ebenenmodell f{\"u}r Datenmodelle solcher
Anwendungen, das verschiedene Probleme und Aufgaben im Entwurf der Daten, der
Adaptionslogik und der Verarbeitung kapselt. Die Ebenen werden anhand des
Nexus-Ansatzes diskutiert, dessen Ziel es ist, mobile, kontext-bezogene
Anwendungen durch f{\"o}derierte Kontextmodelle zu unterst{\"u}tzen, und mit verwandten

abstract = {The automation of application provisioning and management is one of the most
important issues in Cloud Computing. However, the steadily increasing number of
different services and software components employed in composite Cloud
applications leads to a high risk of unintended side effects when different
technologies work together that bring their own proprietary management APIs.
Due to unknown dependencies and the increasing diversity and heterogeneity of
employed technologies, even small management tasks on a single component may
compromise the whole application functionality for reasons that are neither
expected nor obvious to non-experts. In this paper, we tackle these issues by
introducing a method that enables detecting and correcting unintended effects
of provisioning and management tasks in advance by analyzing the context in
which the tasks are executed. We validate the method practically and show how
context-aware expert management knowledge can be applied fully automatically to
provision and manage running Cloud applications.},
