This document introduces the Unified Service Description Language (USDL), which aims to describe services from a business, operational, and technical perspective. USDL was created to address limitations in existing specifications that focus only on technical aspects and do not capture important business characteristics. The document outlines requirements for a service description language, discusses different types of service marketplaces, and presents an overview of the USDL metamodel which brings together business, operational, and technical views of a service.
Semantic Web services (SWS) aims at extending traditional Web services
with machine-readable semantic descriptions of their functionality and
interfaces in order to increase the degree of automation for
service-based applications, e.g., by allowing the discovery, binding
and composition of services to be performed automatically.
This talk will provide a quick introduction to Semantic Web Services,
will discuss what have been the past achievements in this research area. The talk will also try to
analyze what are the problems that are hindering semantic web services to be largely adopted and how
future work in the area can contribute to solve such issue.
This document provides an overview of web services and related standards. It discusses the motivation for using web services to enable application-to-application communication. The five fundamental web services standards are XML, HTTP, WSDL, SOAP and UDDI. WSDL is described in detail, including how it is used to define service interfaces and operations. Examples are provided to illustrate WSDL elements and structure.
A Novel Framework for Reliable and Fault Tolerant Web ServicesAbhishek Kumar
This document proposes a novel framework for providing reliable and fault tolerant web services. The framework uses replication and a replication manager to select a primary web service from among multiple replicas. When the primary web service fails or becomes unavailable, the replication manager switches to a new primary by updating the WSDL registration to ensure uninterrupted service for consumers. The replication manager continuously monitors the web services and can trigger recovery, reconfiguration or restart processes to maintain reliability. The proposed approach aims to achieve high performance and reliability for web services.
This document discusses web services and service-oriented architecture (SOA). It begins by defining a web service as a software system designed to support interoperable machine-to-machine interaction over a network using standards like WSDL and SOAP. SOA promotes the use of web services by defining all functions as services that can be discovered and invoked. The document then explores how SOA and web services can benefit e-business applications by enabling faster and cheaper integration between partners and internal systems. It also provides an overview of key SOA technologies like UDDI, WSDL, and SOAP.

When innovative new services are introduced to market and society, it is usually the case that a group of service providers (frequently through the leadership of a sector dominant provider) form an alliance that implements the new service as a composition of some of their own offerings (services or goods and resources). The participating service providers set their own business objectives in order to enter the coalition, and these will have to be satisfied if the emerging service system is to be successful against the competition and sustainable in the long run. One of the many interesting questions that emerge in this context is the following: how can these business objectives be translated to appropriate constraints for the design of the necessary business processes and for resource and infrastructure services (cloud) provisioning? How can these - structure of the service system, business processes, infrastructure services - be adapted to a changing and competitive business environment so that old or new business objectives are still met?
I will present some initial research results that can provide a first handle to these problems. I argue that we need a fresh, holistic approach to deal with them. We have to gain a deeper understanding of how value is created in service systems,how people and systems contribute to this creation, and how sensitive this value creation is to our, most of the time, unsuspecting technical decisions on IT systems and infrastructures. I will also discuss a first attempt towards a unified quantitative framework that could be useful towards addressing these issues and concerns.
The document discusses the Linked-USDL (Unified Service Description Language), which is an ontology for describing services using semantic web principles. It provides an overview of the Linked-USDL modules, syntax, core classes and properties for describing services, service models, offerings, interactions and more. The goal is to develop a standardized way to describe services in a holistic manner, covering both business and technical aspects.

System airline as one of business to customer (B2C) is an enterprise application
which needs service system architecture. Many systems that have been connected to
this system has complexity of integration. SOA using enterprise service bus (ESB) is
one way to manage the integration of information systems. ESB is a software
infrastructure that can solve complexity problems with n-to-n integration, where n is
the number of integrated applications. The business case has been implemented each
function of services and ESB. The results obtained show that each services and ESB
has its own strengths and weakness. As regards strengths, it should be noted that ESB
copes very well with both kinds of files and small and large size but put the effort if the
application of ESB is not working well it can be affected to another application
system. N-to-n integration performs as good enough with small files and size but need
to manage if there were any add or updated with the service. This research
implemented SOA using ESB to proves to be a good choice for integration solution in
a business environment with a large number of users and diversified communications
The document discusses leveraging a service-oriented and model-driven approach to enterprise architecture. It introduces key concepts like enterprise architecture, service-oriented architecture, and model-driven architecture. It provides an example of modeling a "Dealer Network" as a services architecture using these concepts.
This document discusses Microsoft's vision and strategy around service-oriented architecture (SOA) and integration. It outlines how Microsoft platforms like .NET 3.0, Windows Workflow Foundation, and BizTalk Server enable the development of composite and integrated applications using SOA principles. The document also provides examples of how major financial institutions are using Microsoft technologies in mission-critical applications.
The document discusses moving from silo-based development to a modular, open architecture based on service-oriented architecture (SOA). It notes that typical IT budgets spend 70-90% on maintenance due to rigid, monolithic applications. SOA defines services as modular, loosely coupled units that can be reused. The document recommends a phased approach to SOA implementation and provides examples of SOA adoption in Israel, highlighting challenges around monitoring, operations, and organizational issues.
The document summarizes a presentation given by Simeon Simeonov of Polaris Venture Partners on the status and future of web services from both end user and investor perspectives. Key points discussed include the current state of web services adoption, market analysis of web services categories and companies, case studies of large companies implementing web services, and lessons learned for startups, end users, and the industry.
Value Creation from IS Integration: From ASP to Web Services?webhostingguy
The document discusses the transition from ASPs to web services and the benefits of web services for integration. It notes that early ASP models were flawed as they focused too much on marketing and commoditized applications rather than creating value. Web services allow for greater customization, integration across business processes, and many-to-many relationships that facilitate collaboration and innovation across organizations. The transition to web services represents a shift from application-centric to process-centric systems and will drive changes in business models and industry structures.

The document introduces SOA and discusses its key concepts. It describes why organizations adopt SOA, defines what SOA is, and outlines some of its benefits including reuse, flexibility and cost savings. It also discusses components of a SOA system like services, service contracts and an enterprise service bus.
The document discusses how service-oriented architecture (SOA) impacts IT infrastructure and introduces new considerations for performance, security, availability, service management, and virtualization. Key points include:
- SOA introduces new infrastructure components like XML gateways and introduces challenges for monitoring distributed applications and isolating performance bottlenecks.
- Security must be implemented across multiple layers to secure messages in SOA environments while propagating identities among partners.
- High availability, disaster recovery, and scalability require techniques like clustering, workload management, and data replication across SOA components.
- Service management requires monitoring all components and closing the loop between infrastructure events and business services.
- Virtualization can help decouple applications from infrastructure

Massonet Philippe Panel - Security in the clouds: An Academic PerspectiveServiceWave 2010
The document discusses security challenges in cloud computing from an academic perspective. It notes that cloud providers are offering different security levels and obtaining certifications to improve trust. However, key challenges remain around loss of user governance, compliance, managing risks from jurisdiction changes, and lack of transparency. The responsibilities between users and providers are also still incompletely defined regarding accountability and control. The document suggests research directions could improve trust by giving users more control and verifying the provider's isolation of virtual infrastructure.

Finally, it lists the panelists who will discuss challenges
Martine Lapierre - Security in Cloud computing: sharing more than resourcesServiceWave 2010
Cloud computing provides opportunities but also implies a loss of control over data and infrastructure. When choosing a cloud offering, considerations include the provider's reputation for protecting confidentiality and their ability to prove no loss of control. Sensitive healthcare data processed in the cloud must satisfy strict regulatory requirements regarding data protection, access controls, and ensuring data does not leave its country of origin. Both customers and providers face legal and security challenges in ensuring compliance with privacy laws and protecting against threats in shared cloud environments.

FIRESTATION aims to coordinate and support stakeholders involved in the Future Internet Research and Experimentation (FIRE) initiative. It establishes an Architecture Board to bring together representatives from FIRE projects to coordinate common actions and developments. This includes working towards a high-level federation model for FIRE facilities, developing a common FIRE portal, and addressing sustainability and business models. FIRESTATION also serves as an entry point for external relations and provides support for other coordination actions like FIREBALL and PARADISO2.
This document discusses testbeds for service deployments and summarizes a panel discussion on the topic. The panel motivation was that fast prototyping, testing, and experimentally driven research are key to speeding up and leveraging new application and service deployments. Testbeds can offer existing solutions and determine if they are usable and adequate. Some issues discussed were matching or mismatching between needs, requirements, and available solutions both open and commercial. Questions addressed why common open activities and solutions may need to be developed for service platforms, what concrete form an offering could take, and how academic and industrial objectives could be reconciled along with business models and sustainability.

Recent years have seen a disturbing rise in violence, discrimination, and intolerance against Christian communities in various Islamic countries. This multifaceted challenge, deeply rooted in historical, social, and political animosities, demands urgent attention. Despite the escalating persecution, substantial support from the Western world remains lacking.
मद्रास उच्च न्यायालय के सेवानिवृत्त न्यायाधीश और केंद्र और राज्य सरकार के नौकरशाहों सहित आठ अन्य लोगों की अध्यक्षता वाली एक उच्च स्तरीय समिति ने 2021 में NEET परीक्षा को खत्म करने की सिफारिश की थी। महत्वपूर्ण बात यह है कि रिपोर्ट में 2010-11 में ग्रामीण पृष्ठभूमि से तमिल छात्रों की संख्या में 61.5% की भारी गिरावट को दर्शाया गया है। इसके बजाय मेट्रो छात्रों में वृद्धि दर्ज की गई है।

Skarzynski and Gibson 2008 “… is a conceptual framework for identifying how a company creates, delivers, and extracts value. It typically includes a whole set of integrated components, all of which can be looked on as opportunities for innovation and competitive advantage”.

The Value Delivery Modeling Language is under development in response to the OMG Value Delivery Metamodel (VDM) RFP issued March 27, 2009. This PPT provides an overview of the current concepts and capabilities of the specification.
This diagram illustrates the role of value propositions in exchanges between business entities, typically independent companies. The relationship between these business entities is defined as a value exchange. Each participant gives and receives a value proposition with each of the other participants with which they interact. The illustration incorporates an Internet business relationship between three participants. An Internet Publisher provides an information service of interest to customers. An advertiser pays the publisher to include advertisements for its products along with the information sought by the customer. The customer then clicks on ads of interest and potentially purchases goods from the advertiser. For this business relationship to survive, each of the participants must experience a net gain. In this case, each participant provides two value propositions and receives two value propositions. There may not be a net gain between any two participants, alone, but each has a net gain for the overall exchange.
These are the primary dimensions represented by a VDML model. The activity network defines the roles of activities. Activities are linked by the transfer of deliverables, so the nature of each deliverable and its producers and consumers are of interest. Organization relationships define how capabilities are managed and coordinated. The contributions to value propositions define the sources of value and their impact on value propositions. Exchange networks represent the relationships between business entities. Performance monitoring provides visibility of the composite performance and the effects of changes in the model.
These are business design and modeling techniques that are influencing the development of VDML. We hope to integrate the best aspects of these techniques.
A BPMN Collaboration diagram describes the messages exchanged between the participants. The Collaboration diagram provides an ungrouped view of the messages exchanged between the participants. A Communication diagram can be used to show how the messages are grouped. The BPMN 2.0 FTF is in the process of merging the Collaboration and Conversation diagrams.
A BPMN Conversation shows the grouping of messages between collaborating participants and provides a means to correlate interactions between specific instances of these participants at runtime. These groupings correspond to the messages shown in the collaboration diagram. The choreography of these groups of messages can be shown using a Choreography diagram The grouping of messages, plus the corresponding choreography corresponds to the ServiceInterface in SoaML. The connections between the communication and participants in a communication diagram corresponds to the service and request ports in SoaML.
This is a new type of drill down into a Conversation. It not only shows the Message Flow, it shows a Choreography of the Conversation. We will have to consider if we need BPMN 2.0 FTF issues to do this, since there could be a Choreography for each Conversation. The convergence of Collaboration and Conversation will help, but only one Choreography is allowed in a Collaboration. But that Choreography could have multiple Start Events. What is needed is a way to visually and semantically connect the messages, their grouping and their sequencing captured in a BPMN collaboration, communication and choreography. One possible approach is to support drill-down into a communication to see the messages and their choreography. This could be done through naming conventions where the names of the communication and collaboration are the same, as well as the start activity in the choreography.
Participant is a definition in SoaML. A part (or typed element) is a reference to some instance of a participant, the actual instance would be established by an assignment statement that usually happens at runtime and is not usually modeled. Again the normalization of message-oriented vs procedure-call-oriented is not yet covered by BPMN. These are currently completely separate concepts in BPMN with message-oriented interactions being covered by collaboration, communication and choreography, and specific send and receive message activities in an orchestration. Procedure-call-oriented is covered by interface and service activity in an orchestration. BPMN’s modeling of services is limited to simple interfaces as in WSDL. Service protocols and complex service interactions would have to be modeled using the message-oriented approach.
