## Web Services

- Directory

- Find

- Consumer

- Service

- Publish

**Interact**

- UDDI, WS-Inspection

- SOAP, SwA, ebXML Messaging Service

- XML, WSDL, XSD, XSLT

- IP, DNS, URL, HTTP, HTTPS

- Note:  The current focus is on the **Interact** component of Web Service using SOAP technology.

## Web Services Examples

- Borders provides Web visitors with detailed maps and driving directions for all locations that makes finding the nearest Borders store quick and easy.
- Cendant (parent company to Century21, ERA and Coldwell Banker) taps into powerful mapping engines helping clients locate homes and the nearest realtor office.
- Travelocity.com offers a hotel-booking tool, which enables travelers to search for hotels near a specific location with as much or as little information as is available using the MapQuest search engine.

- MapQuest offers a Web Services system that allows for flexible integration of the MapQuest search engine on various Web sites.

## Web Services Examples

- MarketWatch powers the Motley Fool news alerts as part of _[www.fool.com](http://www.fool.com/)_
- Citibank offers CBS MarketWatch news and portfolio tracker on the Citi.com site
- AG Edwards has integrated MarketWatch news and price alerts into the AGe-Connect site.
- CSFBdirect customers are able to access CBS MarketWatch real-time and symbol-specific news, as well as a suite of proprietary market columns via the CSFBdirect portal.

- CBS MarketWatch offers a Web Service integration tool through BigCharts.com that allows for flexible use of its Stock Tickers and Market Charts on various Web sites.

## Key Web Services Benefits

- Provide a straightforward, low entry cost mechanism for system-to-system interaction between companies
- Based on a set of industry standard protocols and technologies available on all platforms
- Support the reuse and extension of existing components/applications
- Enables just-in-time integration - allowing disparate business services to be federated into a composite, value-added business function without intervention from a programmer
- Technically enables communication between diverse technologies – within an organization - and externally to trading partners, customers and suppliers
- Web services are *additive*, not necessarily *replacement*, technology

**Web Services Compliments Overall Data Strategy**

## Core Web Standards

**The core standards are already defined**:
***Discovery***
- Web Services are registered in central registries (UDDI) and can be discovered there
***Description***
- Web Service provider describes its services with all details via a standard XML document called WSDL
***Messaging***
- Use of XML as the basis for document centric messaging protocol. SOAP is establishing itself as the foremost message protocol for Web Services
***Transport***
- Defines the protocols used to transport messages. HTTP is the de facto standard network protocol for Internet-available Web Services

- Web Services technologies are driven by standards supported by all vendors to maximize interoperability.

**Core Web Standards**

## Web Services Technologies

- Web services:
- are based on Internet standards
- are platform agnostic
- are widely available
- have complete vendor support
- are a key enabler of SOAs (Service Oriented Architectures)

**Web Services are a developing capability that build on both existing and new technologies /standards.  Rarely is a web service mentioned without discussion of XML.  Other protocols such as SOAP are viewed as the most likely standard for wrapping XML - but the technologies are still evolving.**

**Core Web service standards**

## Web Services -  The Technologies in Detail

**XML (Extensible Markup Language) **-** **Platform independent, language-neutral data representation format

**SOAP (Simple Object Access Protocol)** - Lightweight, extensible protocol for information exchange across different systems and protocols.  Part of the SOAP specification defines a set of rules for how to use XML to represent data.  Other parts of the SOAP specification define an extensible message format, conventions for representing remote procedure calls (RPCs) using SOAP message format, and bindings to the HTTP protocol.

**WSDL (Web Service Description Language) **- An XML-based contract language that defines a standard mechanism for documenting what messages a Web Service accepts and generates (i.e. interfaces).

**UDDI (Universal Description, Discovery, and Integration)** -  Specifies a mechanism for Web Service providers to advertise the existence of their Web Services and for Web Service consumers to locate Web Services of interest.  UDDI Registries offer data, metadata, bindings, pointers, and documents for finding and invoking Web Services that includes client and server APIs for publishing to, editing, and querying registry entries.

## Web Services - How do they compliment FSA Strategies?

- Build/Leverage in place XML Schemas
- Ease Data Integration concerns
- Assist in the movement from batch process to web based “real-time” information exchange
- Provide means for accessing FSA internal systems as well as joint development of standards and access with external parties
- Further FSA’s ability to match customer expectations  - parallel convenience/accessibility of commercial industry
- As Messaging Maturity and Capability increases Web Services are a clear next step

**Possible Business Functions that could be enabled by Web Services**

## Considerations for Web Services

- Web Services allow the sharing of information between parties via distinct business functions.
- What business functions could FSA provide to the community?
- What business functions are you currently using with other clients?
- Do you have any lessons learned from pilots or implementations?
- What are the best practices that you have discovered along the way?
