....to make programs more flexible and powerful by consulting Internet databases (registries) at runtime in order to discover information and network attached third party building blocks. While important advances have recently been made in the field of web service specification [8] invocation [9] and registration [10] the problem of how to use a rich and expressive general purpose query language to discover services that o#er functionality matching a detailed specification has so far received little attention. In a large distributed system spanning many administrative domains, the ....

....interface . How operations and arguments are bound (mapped) to network protocols and endpoints The formalism should be su#ciently general to encourage broad acceptance and smooth evolution. For example, it should not only support the needs of future services and protocols (e.g. using SOAP HTTP [9] or SOAP BEEP [31] but should also be able to describe the typical operations of services using existing protocols such as FTP [32] SMTP [33] HTTP [34] and BEEP [35, 36] Since the purpose of this section is to expose fundamental concepts rather than syntactic details, a precise formalism is ....

.... multiplexing for scalable query concurrency (some RDBMS drivers, HTTP based mechanisms, LDAP, MDS) Some do not encourage interoperability and extensibility based on open IETF standards (RDBMS, Gnutella, Freenet) Interesting directions for future research include investigating the use of SOAP [32] as a high level tool for PDP messaging. Most commonly, HTTP 1.1 [33] is used as SOAP transport. However, SOAP is transport protocol independent. For strongly increased e#ciency and low latency, SOAP should be carried over BEEP. See [34] for an IETF draft specifying a straightforward SOAP BEEP ....

....in varied areas such as distributed supercomputing [1, 21] smart instruments [18] and teleimmersion [5] The authors contributed to this work when they were undergraduate students at New York University. while web service connectivity and description standards such as HTTP [25] SOAP [26], and WSDL [27] have proven critical to the growth of web commerce. In each case, the infrastructure enables application components to plug in into a common substrate, which provides core functionality naming, discovery, multi protocol binding, authentication, and authorization.

....and RDBMS. Spitfire grid enables a wide range of relational databases by introducing a uniform service interface, data model, network protocol and security model. These are based on widely accepted standards (e.g. OGSA [11] WSDA [12] URIs [13] HTTP [14] TLS [15] GSI [16] XML [17] SOAP [18], WSDL [19] and neutral with respect to programming language, platform and database product. Spitfire is easy to use, e#cient, flexible, and some projects (Alice, Atlas) are starting to use it. This paper is organized as follows. Section 2 describes the architecture of the latest stable Spitfire ....

....line client or HTTP API to issue an HTTP request like http: spitfire.cern.ch getPFNs.xsql table=repcat lfn=lfn: cms.org file1 Performance. With the design goal to provide high performance and low latency Java servlets were chosen since they are highly e#ciency and provide a scalable solution [18]. To minimize the number of connection setups, persistent HTTP(S) 1.1 connections [14] are used (but not required) For similar reasons, the services use thread and JDBC connection pooling, and advanced caching. The net e#ect is that requests and responses are passed through layers with very ....

Service descriptions provide documentation for distributed systems and serve as a recipe for automating the details involved in application communication [4] In contrast to popular belief, a web service is neither required to carry XML messages, nor to be bound to SOAP [5] or the HTTP protocol, nor to run within a .NET hosting environment, although all of these technologies may be helpful for implementation. For clarity, service descriptions in this chapter are formulated in the Simple Web Service Description Language (SWSDL) as introduced in our prior studies ....

Services can advertise themselves and related metadata via such databases, enabling the assembly of distributed higher level components. While advances have recently been made in the field of web service specification [4] invocation [5] and registration [8] the problem of how to use a rich and expressive general purpose query language to discover services that o#er functionality matching a detailed specification has so far received little attention. A natural question arises. How precisely can a local application discover ....

While advances have recently been made in the field of web service specification [6] invocation [7] and registration [8] the problem has so far received little systematic conceptual attention. A key question then is: What distinct problem areas and processing steps can be distinguished in order to enable flexible remote invocation in the context of web service discovery This paper ....
