It is a visual approach based on the use of software models and graph transformations and allows for the description of innovative services while providing a precise matching concept.  ...  Web Services are software components that can be discovered and employed at runtime using the Internet. Conflicting requirements towards the nature of these services can be identified.  ...  Modeling the Semantics of Web Services with Ontologies and Graph Transformation Rules The case for models Web Services are not a stand-alone technology.  ...

Model-Based Development of Web Services Descriptions Enabling a Precise Matching Concept

Jan Hendrik Hausmann, Reiko Heckel, Marc Lohmann
2005 International Journal of Web Services Research  
It is a visual approach based on the use of software models and graph transformations and allows for the flexible description of innovative services while providing a precise matching concept.  ...  Web services are software components that can be discovered and employed at runtime using the Internet. Conflicting requirements towards the nature of these services can be identified.  ...  After selecting the best of these services, the client is able to use the Web service directly by contacting the provider.  ...

Automatic Conformance Testing of Web Services [chapter]

Reiko Heckel, Leonardo Mariani
2005 Lecture Notes in Computer Science  
In this paper, we propose the idea of high-quality service discovery incorporating automatic testing for validating Web Services before allowing their registration.  ...  Web Services are the basic building blocks of next generation Internet applications, based on dynamic service discovery and composition.  ...  The latter computes the recommended length of a paddle, given the height of the person who will use it. Both Web Services provide one single simple operation.  ...

Towards Federated Queries for Web of Things Devices

Sejal Jaiswal, Maxime Lefrançois
2017 International Conference on Semantic Systems  
The core of this solution is an extension of SPARQL-LD. The SPARQL SERVICE clause is extended and can be used to query also non-RDF sources for which we know some RDF lifting mechanism.  ...  In the emerging Web of Things (WoT), a vast majority of devices do not consume nor produce RDF, notably because of their inherent constraints that prevent them from manipulating textual RDF syntax.  ...  We then transform the data de ned in the lifting rule and execute the subquery against the resulting RDF graph.  ...

A Survey of Automated Web Service Composition Methods [chapter]

Jinghai Rao, Xiaomeng Su
2005 Lecture Notes in Computer Science  
This paper gives an overview of recent research efforts of automatic Web service composition both from the workflow and AI planning research community.  ...  In today's Web, Web services are created and updated on the fly. It's already beyond the human ability to analysis them and generate the composition plan manually.  ...  In that case, only the selection and binding of atomic Web service is done automatically by program. The most commonly used static method is to specify the process model in graph.  ...

A Semantic Web Services Approach Towards Automated Software Engineering

Ulrich Dinger, Roy Oberhauser, Christian Reichel
2006 2006 IEEE International Conference on Web Services (ICWS'06)  
To address these challenges, this paper explores the practicality of a unifying Semantic Web Services approach towards Automated Software Engineering (SWS-ASE).  ...  A common infrastructure is missing that provides an interoperable and distributed tool environment, addresses feature dependency selection, and automates toolchain workflow composition and execution.  ...  Architectures (SOAs)/Web Services (WS) and the Semantic Web vision [1] .  ...

A framework towards web services composition modelling and execution

Muhammad Adeel Talib, Zongkai Yang, Qazi Mudassar Ilyas
2006 International Journal of Web and Grid Services  
In this paper we propose our framework leading to a tool that aids business user in designing Web service based process (or in other words, Web service compositions) in BPEL4WS.  ...  and towards the business process owners themselves.  ...  For this functionality we propose the use of a service broker that provides the service URLs upon queries based on functional and non-functional requirements.  ...

Towards Distributed BPEL Orchestrations

Luciano Baresi, Andrea Maurino, Stefano Modafferi
2007 Electronic Communications of the EASST  
Web services are imposing as the technology to integrate highly heterogeneous systems.  ...  An explicit meta-model and graph transformation supply the formal grounding to obtain a set of related processes, and to add the communication infrastructure among the newly created processes.  ...  Partitioning rules Partitioning rules must be precise enough to allow for correct and automatic transformations and are supposed to work on the graph structure (i.e., an instance of the meta-model) that  ...

Towards Contract-based Testing of Web Services

Reiko Heckel, Marc Lohmann
2005 Electronical Notes in Theoretical Computer Science  
In this paper, we propose to visualize contracts by graph transformation rules which blend well with a UML-based notion of data models and signatures.  ...  The operational interpretation of rules could turn out to be useful for simulating the behavior of required components in unit testing.  ...  On this account we use graph transformation rules for both: a description of an offered service and as the formulation of a request.  ...

Ontology-Driven Conceptual Design of ETL Processes Using Graph Transformations [chapter]

Dimitrios Skoutas, Alkis Simitsis, Timos Sellis
2009 Lecture Notes in Computer Science  
A graphbased representation is used as a conceptual model for the source and target data stores. We then present a method for devising flows of ETL operations by means of graph transformations.  ...  In particular, the operations comprising the ETL process are derived through graph transformation rules, the choice and applicability of which are determined by the semantics of the data with respect to  ...  Section 3 presents the use of the ontology as a common conceptual model to drive the selection and composition of ETL operations, based on a set of appropriately defined graph transformation rules.  ...

Three AO4BPEL examples, taken from the literature, are used to test the suitability of graph transformation as a means to simulate BPEL aspects.  ...  This paper explores if algebraic graph transformation rules can be used to specify BPEL aspects at the modeling level, and make new aspect languages like AO4BPEL redundant.  ...  Acknowledgment The work reported in this paper has been funded by The Research Council of Norway, grant no. 167172/V30 (the SWAT project), and by the ENVISION project grant no. 249120 (EU FP7).  ...

Marko Boskovic, Ebrahim Bagheri, Georg Grossmann, Dragan Gasevic, Markus Stumptner
2011 Canadian Semantic Web Symposium  
In this position paper, we propose a methodology for integration that employs ontologies and Semantic Web technology, and propose a tool support that supports the proposed methodology.  ...  Success of a Software Product Line (SPL) typically induces increase of requirements that expand over the expertise of its initial company.  ...  In their work they provide a set of rules, and with the means of graph transformation, they perform the merge.  ...
