This document, produced by the OGSA working group within the Global Grid Forum (GGF), provides a first, and necessarily preliminary and incomplete, version of this OGSA definition. The document specifies the scope of important services required to support Grid systems and applications in both e-science and e-business, identifies a core set of such services that are viewed as essential for many systems and applications, and specifies at a high-level the functionalities required for these core services and the interrelationships among those core services. The document also lists existing technical standards and standard definition activities within GGF, OASIS, W3C, and other standards bodies that speak to required OGSA functionality, and identifies priority areas for further work.   Global Grid Forum   Working Draft     Open Grid Services Infrastructure (OGSI)Building on both Grid and Web services technologies, the Open Grid Services Infrastructure (OGSI) defines mechanisms for creating, managing, and exchanging information among entities called Grid services. Succinctly, a Grid service is a Web service that conforms to a set of conventions (interfaces and behaviors) that define how a client interacts with a Grid service. These conventions, and other OGSI mechanisms associated with Grid service creation and discovery, provide for the controlled, fault-resilient, and secure management of the distributed and often long-lived state that is commonly required in advanced distributed applications.   Global Grid Forum   Proposed Recommendation     SOAP (Simple Object Access Protocol) 1.1SOAP is a lightweight protocol for exchange of information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts: an envelope that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing remote procedure calls and responses. SOAP can potentially be used in combination with a variety of other protocols -- however, the only bindings defined in this document describe how to use SOAP in combination with HTTP and HTTP Extension Framework.   W3C   Note     SOAP (Simple Object Access Protocol) 1.2This is an updated release (on 2003-06-24) of the SOAP protocol specification, the foundation delivery protocol for Web services. The changes between the prevalent version 1.1 and the newer 1.2 are in modified and new syntax, modified SOAP to HTTP binding, refined RPC behavior, and a new model for SOAP encoding data model.   W3C   Specification     WS-AddressingWS-Addressing provides transport-neutral mechanisms to address Web services and messages. Specifically, this specification defines XML elements to identify Web service endpoints and to secure end-to-end endpoint identification in messages. This specification enables messaging systems to support message transmission through networks that include processing nodes such as endpoint managers, firewalls, and gateways in a transport-neutral manner.   IBM, BEA, Microsoft   Specification     WS-NotificationWS-Notification implements the Notification pattern, where a service provider, or other entity, initiates messages based on a subscription or registration of interest from a service requestor. It defines how the publish/subscribe (pub sub) pattern commonly used in Message-Oriented middleware products can be realized using Web services. This includes brokered as well as direct pub sub which allows the publisher/subscribers to be decoupled and provides greater scalability.   IBM, Akamai Technologies Inc., Globus Alliance, Hewlett-Packard, SAP AG, Sonic Software Corporation, Tibco Software Inc.   Specification     WS-PolicyFrameworkThe Web Services Policy Framework defines a general purpose model and corresponding syntax to describe and communicate Web services policies so that Service consumers can discover the information they need to know to be able to access services from a Service Provider.   IBM, BEA, Microsoft, SAP, Sonic Software, VeriSign   Specification     WS-ReliableMessagingThis specification (WS-ReliableMessaging) describes a protocol that allows messages to be delivered reliably between distributed applications in the presence of software component, system, or network failures. This updated version is based upon the suggestions collected from the WS-ReliableMessaging Feedback Workshop held in July 2003 and the Interoperability Workshop help in October 2003. The protocol is described in this specification in an independent manner allowing it to be implemented using different network transport technologies. To support interoperable Web services, a SOAP binding is defined within this specification.   IBM, BEA, Microsoft, TIBCO   Specification     WS-ResourceLifetimeWS-ResourceLifetime defines two ways of destroying a WS-Resource: immediate and scheduled. This allows designers flexibility to design how their Web services applications can clean up resources no longer needed.   IBM, Globus Alliance, Hewlett-Packard   Specification     WS-ResourcePropertiesWS-ResourceProperties defines how the data associated with a stateful resource can be queried and changed using Web services technologies. This allows a standard means by which data associated with a WS-Resource can be accessed by clients. The declaration of the WS-Resource's properties represents a projection of or a view on the WS-Resource's state. This projection represents an implied resource type which serves to define a basis for access to the resource properties through Web service interfaces.   IBM, Globus Alliance, Hewlett-Packard   Specification     WS-SecureConversationThe Web Services Secure Conversation Language is built on top of the WS-Security and WS-Policy models to provide secure communication between services. WS-Security focuses on the message authentication model but not a security context, and thus is subject several forms of security attacks. This specification defines mechanisms for establishing and sharing security contexts, and deriving keys from security contexts, to enable a secure conversation.   IBM, BEA, Computer Associates, Layer 7 Technologies, Microsoft, Netegrity, Oblix, OpenNetwork Technologies, Ping Identity Corp, Reactivity, RSA Security, VeriSign, Westbridge Technology   Specification     WS-Security 1.0Web Services Security (WSS) offers a trusted means for applying security to Web services by providing the necessary technical foundation for higher-level services. WSS builds upon existing security technologies such as XML Digital Signature, XML Encryption and X.509 Certificates to deliver an industry standard way of securing Web services message exchanges. Providing a framework within which authentication and authorization take place, WSS lets you apply existing security technology and infrastructure in a Web services environment.   OASIS   Open Standard     WS-Security AddendumThis addendum to the WS-Security specification clarifies elements released in the original document and introduces some new items including timestamps, and passing around passwords and security certificates.   IBM, Microsoft, VeriSign   Supplemental Information     WS-Security Kerberos BindingThis document describes how to use Web services Security Specifications with Kerberos.   IBM, Microsoft   Specification     WS-SecurityPolicyThe Web Services Security Policy Language defines a model and syntax to describe and communicate security policy assertions within the larger Policy Framework. It covers assertions for security tokens, data integrity, confidentiality, visibility, security headers and the age of a message.   IBM, Microsoft, RSA, VeriSign   Specification     WS-TrustThe Web Services Trust Language (WS-Trust) uses the secure messaging mechanisms of WS-Security to define additional primitives and extensions for security token exchange to enable the issuance and dissemination of credentials within different trust domains.   IBM, BEA, Computer Associates, Layer 7 Technologies, Microsoft, Netegrity, Oblix, OpenNetwork Technologies, Ping Identity Corp, Reactivity, RSA Security, VeriSign, Westbridge Technology   Specification     WSDL (Web Services Description Language) 1.1WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints (services). WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate, however, the only bindings described in this document describe how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME.   W3C (IBM and Microsoft)   Note     WSDL (Web Services Description Language) 1.2This is an update (Draft 11 2003-06) to the WSDL protocol specification, the foundation description protocol for Web services. The changes currently suggested for version 1.2 include new definitions on message patterns and WSDL bindings for SOAP version 1.2.   W3C (IBM and Microsoft)   Working Draft
