Subject: [regrep] "Top 5 Features I Would Like to See in a Registry..."
Greetings, Just wanted to pass this along as an FYI from the federal realm... The e-mail below is from Brand Niemann, Chair of the Federal CIO Council's Web Services Working Group. He asked me at our recent meeting of the XML Registry Working Group (of which he and I are both members) for my "Top 5 Features I Would Like to See in a Registry" in the federal government; my response was passed on to the Web Services Working Group. The rest is unrelated to registries - it is a presentation on the emerging Global XML Web Services Architecture (GXA) - WS-Security and more, that I will be giving at the Web Services Working Group in the coming months. Kind Regards, Joe -----Original Message----- From: Brand Niemann To: CIOC-WEB-SERVICES@LISTSERV.GSA.GOV Sent: 1/27/2003 8:24 AM Subject: Top 5 Features I Would Like to See in a Registry and Global XML Web Services Architecture (GXA) At my request, Joe Chiusano has provided the following: 1. Top 5 Features I Would Like to See in a Registry (in no particular order): (1) Namespace Management function - Would include capabilities such as: (a) Register namespaces (along with their XML namespace identifiers) (b) Associate registered elements/attributes/datatypes ("artifacts") with their namespaces (c) Report on all XML artifacts within a given namespace (d) Automatically transfer XML artifacts from one namespace to another (would accordingly update all schemas and XML documents in which these artifacts appear) (e) Perform a "diff" between 2 namespaces (useful for harmonization efforts) (f) Change an XML namespace identifier (would accordingly update all schemas and XML documents in which the namespace identifer is used) (2) Security - Access control policies (perhaps XACML), digital signatures, encryption, etc. (3) Distributed/federated capabilities - Allow multiple "independent" registries to become part of a federation, thereby making their contents visible and accessible to other registries/users (4) Granularity - Ability to register/maintain at the artifact level, not just the schema/XML document level (5) Classification/Taxonomy support And when the Core Components work under UN/CEFACT and OASIS is fully matured, I would add "Core Component Enablement" as another highly desirable feature. 2. Global XML Web Services Architecture (GXA) (See Attached) The Global XML Web Services Architecture (GXA) initiative is a protocol framework designed to provide a consistent model for building infrastructure-level protocols for Web services and applications. In addition to this underlying protocol framework, GXA defines a family of pluggable infrastructure protocols that provide applications with commonly needed services such as security, reliability, and multi-party agreement. GXA provides a set of common facilities that are needed by a wide number of Web services and applications, built on the foundation of XML and SOAP. Some of the specifications released to date include: · WS-Security - Provides a security language for Web services; enhances SOAP messaging with credential exchange, message integrity, and message confidentiality · WS-Policy - A general-purpose specification describing how to express enterprise security policies · WS-Routing - Describes mechanisms for routing SOAP messages without the need to rely on underlying transport mechanisms. · WS-Transaction - Adds transactional/coordination capabilities to Web services · WS-Inspection - Provides a means for flexible discovery of Web services, regardless of the mechanism used to describe them (WSDL, UDDI, etc.) This presentation will provide an overview, history, and future of the GXA initiative, as well as a brief overview of each specification that comprises GXA. <http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dngxa/ html/gloxmlws500.asp> http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dngxa/h tml/gloxmlws500.asp <<GXA Presentation.ppt>>
