“…Emerging standards such as BPEL4WS [13], WSCI [14], WS-Coordination [15], and WS-Transaction [7], layer up functionality related to composition and transactions on top of the basic Web service standards such as SOAP, WSDL, and UDDI [5]. BPEL4WS is particularly related to the work presented in this paper since, in addition to proposing a model for composing Web services, it also presents a way for defining the conversations that a Web service supports.…”

“…The essential benefit they bring to application integration is standardization. In fact, Web service technology builds on top of Web standards and extends them with additional languages and protocols (e.g., WSDL, UDDI, and SOAP [5]) that enable service description, discovery, and interaction. Standardization is important in Enterprise Application Integration (EAI) [6,3], but is critical in the Web where the interaction occurs without a central coordinator and without a central authority.…”

Abstract. Web services are emerging as a promising technology for the effective automation of inter-organizational interactions. Several standards that aim at providing infrastructure to support Web services description, discovery, and composition have recently emerged including WSDL, UDDI, and BPEL4WS. Indeed, advances in this area promise to take cross-organizational application integration a step further by facilitating the automatic discovery and invocation of relevant services. However, despite the growing interest in Web services, several issues still need to be addressed to provide similar benefits to what traditional middleware brings to intra-organizational application integration (e.g., transaction support). In this paper, we identify a framework for defining extended service models to enable the definition of richer Web service abstractions. We also identify and define specific abstractions based on an analysis of existing e-commerce Web portals. Finally, we show how the model and the abstractions are supported by a conversation manager implemented on top of the SELF-SERV platform.

“…Nowadays, UDDI (Universal Description, Discovery, and Integration) was used mostly for services discovery process [1]. But it has some disadvantages as follows [2]: (1) The condition that tremendous WSDL documents are stored on centralized UBR (UDDI Business Registry) servers potentially makes servers become the bottleneck of the system.…”

ABSDM: Agent Based Service Discovery Mechanism in Internet

Abstract. To improve popular services discovery mechanism (UDDI mainly), we propose an agent-based services discovery mechanism. In this mechanism, services information is stored in distributed servers that are regarded as independent agents. These servers are joined into a tree structure; and then, a recursive algorithm was used to distribute searching request over the whole tree. Based on this condition, searching request could be rapidly parallel dealt with.

Abstract. The central goal of Public Key Infrastructure (PKI) is to enable trust judgments between distributed users. Although certificates play a central role in making such judgments, a PKI's users need more than just knowledge of certificates. Minimally, a relying party must able to locate critical parameters such the certificate repositories and certificate validation servers relevant to the trust path under consideration. Users in other scenarios may require other resources and services. Surprisingly, locating these resources and services remains a largely unsolved problem in real-world X.509 PKI deployment. In this paper, we present the design and prototype of a new and flexible solution for automatic discovery of the services and data repositories are available from a Certificate Service Provider (CSP). This contribution will take realworld PKI one step closer to achieving its goal.
