Active XML (AXML) research: Survey on the representation, system architecture, data exchange mechanism and query evaluation

Binh Viet Phan, Eric Pardede
2014 Journal of Network and Computer Applications  
Active XML (AXML) is an extension of XML to exploit the powerful computation ability of peer-to-peer network and Web services technologies.  ...  The management of intensional XML and XML data together in XML documents raises issues such as representation for intensional XML data, AXML-XML data exchange and AXML data query processing.  ...  This type of invocation can occur during the materialization of intensional XML data because an invocation of a Web service can trigger invocations of other Web services.  ...

On the improvement of active XML (AXML) representation and query evaluation

Binh Viet Phan, Eric Pardede, Wenny Rahayu
2012 Information Systems Frontiers  
Active XML (AXML) as intensional data aims to exploit potential computing powers of XML, Web services and P2P architecture.  ...  It is considered a powerful extension of XML to deal with dynamic XML data from autonomous and heterogeneous data sources on a very large scale via Web services.  ...  The flexibility of choosing the best Web services for invocations will assist AXML query evaluation to be more efficient.  ...

Characterization and search of web services through intensional knowledge

Devis Bianchini, Paolo Garza, Elisa Quintarelli
2015 Journal of Intelligent Information Systems  
Specifically, we propose W-DREAM (Web services DiscoveRy via intEnsionAl knowledge Mining), an infrastructure to perform intensional service representation and querying to support application designers  ...  Consequently, more and more service descriptions are becoming available on the network to designers, who often filter them according to keyword-based search, thus obtaining huge amounts of matching results  ...  If the Seekda search engine is used, the designer obtains 36 Web services among search results, split on four pages 1 .  ...

The Active XML project: an overview

Serge Abiteboul, Omar Benjelloun, Tova Milo
2007 The VLDB journal  
The model is based on AXML documents, which are XML documents that may contain embedded calls to Web services, and on AXML services, which are Web services capable of exchanging AXML documents.  ...  In this paper, we describe and motivate the AXML model and language, overview the research results obtained in the course of the project, and show how all the pieces come together in our implementation  ...  In particular, many ideas in the present paper were influenced by discussions with Ioana Manolescu who coauthored several of the papers on AXML that were cited.  ...

Exchanging intensional XML data

Tova Milo, Serge Abiteboul, Bernd Amann, Omar Benjelloun, Fred Dang Ngoc
2005 ACM Transactions on Database Systems  
Recently, the emergence of Web services as standard means of publishing and accessing data on the Web introduced a new class of XML documents, which we call intensional documents.  ...  These are XML documents where some of the data is given explicitly while other parts are defined only intensionally by means of embedded calls to Web services.  ...  Similarly, we use schemas to control the exchange of intensional data and, in particular, the invocation of service calls.  ...

2007 Proceedings of the 4th international workshop on XQuery implementation, experience and perspectives - XIME-P '07  
Our implementation permits concurrent evaluation of DXQ expressions at each server and can produce results extensionally (as XML values) or intensionally (as DXQ expressions).  ...  We present DXQ, an extension of XQuery to support the effective and efficient development of distributed XML applications.  ...  One potential use of DXQ is as an implementation language for Web services.  ...

2004 Proceedings of the 2004 ACM SIGMOD international conference on Management of data - SIGMOD '04  
We also present an implementation that is compliant with XML and Web services standards, and is used as part of the ActiveXML system.  ...  AXML documents are XML documents whose content is given partly extensionally, by explicit data elements, and partly intensionally, by embedded calls to Web services, which can be invoked to generate data  ...  Web services.  ...

Extracting causal graphs from an open provenance data model

2008 Concurrency and Computation  
In this view, provenance is obtained as the result of a query over process documentation.  ...  In this paper, we describe how each of these features aid us in answering the challenge's provenance queries.  ...  Because relationship p-assertions may connect events at different levels of granularity, e.g. at the level of service invocations or at the level of Java procedure calls, the provenance of a workflow result  ...

Adaptive Service Binding with Lightweight Semantic Web Services [chapter]

Carlos Pedrinaci, Dave Lambert, Maria Maleshkova, Dong Liu, John Domingue, Reto Krummenacher
2011 Service Engineering  
Semantic Web Services, that is services that have been enriched with semantic annotations have often been used for providing adaptive service selection by deferring the binding of services until runtime  ...  and rely on complex reasoning for which there are no efficient solutions that can scale to the Web yet.  ...  Instead, an intensional definition using declarative statements regarding the suitability of services is a more appropriate solution.  ...

2010 Proceedings of the 2010 international conference on Management of data - SIGMOD '10  
We demonstrate the viability and efficiency of our approach in experiments based on real-life data provided by popular Web services.  ...  As Web service calls are expensive, our method aims to reduce the number of calls in order to retrieve results with sufficient recall.  ...  The calls are executed via the Mapping Tool (discussed below), which is in charge of remote invocation of the Web services.  ...
