Extensions for Financial Services (XFS) interface specification Release 3.50 - Part 1: Application Programming Interface (API) - Service Provider Interface (SPI) - Programmer's Reference
A key element of the Extensions for Financial Services is the definition of a set of APIs, a corresponding set of SPIs, and supporting services, providing access to financial services for Windows-based applications. The definition of the functionality of the services, of the architecture, and of the API and SPI sets, is outlined in this section, and described in detail in Sections 5 through 10.
The specification defines a standard set of interfaces such that, for example, an application that uses the API set to communicate with a particular Service Provider can work with a Service Provider of another conformant vendor, without any changes.
Although the Extensions for Financial Services define a general architecture for access to Service Providers from Windows-based applications, the initial focus of the CEN/XFS Workshop has been on providing access to peripheral devices that are unique to financial institutions. Since these devices are often complex, difficult to manage and proprietary, the development of a standardized interface to them from Windows-based applications and Windows operating systems can offer financial institutions and their solution providers immediate enhancements to productivity and flexibility.
Specifikacija vmesnika razširitev za finančne storitve (XFS), izdaja 3.50 - 1. del: Vmesnik za programiranje aplikacij (API) - Vmesnik ponudnika storitev (SPI) - Referenca za programerje
Ključni element razširitev za finančne storitve je opredelitev nabora vmesnikov za programiranje aplikacij (API), ustreznega nabora vmesnikov ponudnikov storitev (SPI) in podpornih storitev, ki zagotavljajo dostop do finančnih storitev za aplikacije, ki temeljijo na sistemu Windows. Opredelitev funkcionalnosti storitev, arhitekture ter naborov vmesnikov za programiranje aplikacij in vmesnikov ponudnikov storitev je predstavljena v tem razdelku ter podrobneje opisana v razdelkih 5 do 10.
Specifikacija določa standardni nabor vmesnikov, s pomočjo katerih lahko na primer aplikacija, ki uporablja nabor vmesnikov za programiranje aplikacij za komuniciranje z določenim ponudnikom storitev, deluje s ponudnikom storitev drugega ustreznega prodajalca brez kakršnih koli sprememb.
Čeprav razširitve za finančne storitve določajo splošno arhitekturo za dostop do ponudnikov storitev iz aplikacij, ki temeljijo na sistemu Windows, se je delavnica CEN/XFS sprva osredotočala na zagotovitev dostopa do perifernih naprav, edinstvenih za finančne institucije. Te naprave so pogosto kompleksne, lastniške in jih je težko upravljati, zato lahko razvoj standardiziranega vmesnika do teh naprav iz aplikacij, ki temeljijo na sistemu Windows, in operacijskih sistemov Windows finančnim institucijam ter njihovim ponudnikom rešitev zagotovi takojšnje izboljšave produktivnosti in prilagodljivosti.
