Abstract
Adaptable service systems are service systems that are capable of handling
dynamic changes in both time and position related to users, capabilities, nodes
and changed service requirements. The paper presents a formal framework for
dynamic configuration and reconfiguration of services in TAPAS (Telematics
Architecture for Play-based Adaptable Systems). The framework presented in
this paper, provides representation and reasoning mechanisms for semantic de-
scription and matching of required and offered capabilities and status which
are required by a particular service system. It employs CIM and RDF based on
XML as well as the XML Declarative Description Language (XDD) to provide
human readable and machine-comprehensible descriptions of status, capabili-
ties, system (re)configuration plans as well as the exchange of messages. A rea-
soning system for Configuration Management has been developed by use of
XET (XML Equivalent Transform).
This system can directly operate and reason about XML elements and XML
clauses described by XDD. The system is demonstrated for a simple Intelligent
Printing Management System.

Summary
The paper presents capability initialization and capability re-initialization
of the capability configuration management for adaptable service systems. The
paper focuses on three aspects:
• TAPAS architecture
• Dynamic configuration framework for capability initialization and
re-initialization
• Data representation
TAPAS architecture is separated into a computing architecture and a sys-
tem management architecture. The computing architecture is a generic architec-
ture for modeling any service systems and their components. The system man-
agement architecture is the structure of the system management components. In
the computing architecture, a service consists of service components that are
realizing by roles and deploy on physical nodes.
The capability configuration and re-configuration determine appropriate
nodes to deploy roles and instantiate role figures. This is accomplished by a dy-
namic configuration framework constituting configuration management func-
tionality in the system management architecture. Dynamic means that the capa-
bility configuration is not fixed and can be determined based upon available ca-
pability and service performance measures of nodes. An XET-based reasoning
machine works as a capability configuration manager that transforms a service
request, a service component request or a trouble report into a configuration
plan for a service manager to deploy the needed roles.
Scenario S2 – printing system capability initialization and re-initialization
describes the composition of dynamic capability configurations for an Intelli-
gent Printing Management (IPM) service system. The required capability and
service performance measures of each role are defined in play (re-
)configuration rules used by the configuration manager. Based upon available
capability and service performance measures of nodes, roles can be instantiated
at the nodes with the sufficient capabilities and service performance measures.

Abstract
To be able to utilize the generative potential of future networks for service
composition, the attributes of services and networks must be appropriately for-
malized, stored and made available. Important attributes are the capability and
the status. A capability is an inherent property of a node or a user, which de-
fines the ability to do something. A capability in a network node is a feature
available to implement services. A capability of a user is a feature that makes
the user capable of using services. Status is a measure for the situation in a sys-
tem. This paper proposes a representation framework for capability and status,
denoted as Unified Capability and Status Representation Framework (UniCS).
This framework is used to decide upon dynamic use of capabilities, and is used
to support the dynamic composition of a service system. UniCS consists of facts
and configuration rules. The facts describe the availability and requirement of
capabilities and status of a service system. The configuration rules verify, ma-
nipulate, transform and discover new facts with defined axioms and constraints.
An instance of UniCS is the input specification for a reasoning engine to dy-
namically generate a composition plan for a service system.

Summary
A dynamic service composition framework is presented in Paper C. This
paper extends the capability initialization in Paper B by making a generic policy
system definition for capability initialization, which is the main achievement of
this paper. The demonstration scenario is this paper is scenario S2 – printing
system capability initialization and re-initialization.
