Service-Level Agreement: A contract or memorandum of agreement between a service
provider and a customer that specifies, usually in measurable terms, what services the service
provider will furnish. Information technology departments in major enterprises have adopted the
idea of writing a service level agreement so that services for their customers (users in other
departments within the enterprise) can be measured, justified, and perhaps compared with
those of external (sourcing) service providers.
Service-Oriented Architecture: Architecture that provides for reuse of existing business
services and rapid deployment of new business capabilities based on existing capital assets.
Services Interface: A logical boundary that permits software services to be defined
independent of the service implementation.
SOAP: A simple XML based protocol to let applications exchange information over HTTP.
SOAP is a protocol for accessing a Web Service. Note, SOAP originally stood for Simple
Object Access Protocol, but this has been dropped.
Single Sign On (SSO): is an optimization of the authentication sequence to remove the burden
of repeating actions placed on the end user. To facilitate SSO, an element called an Identity
Provider can act as a proxy on a user's behalf to provide evidence of authentication events to
3rd parties requesting information about the user. These Identity Providers are trusted 3rd
parties and need to be trusted both by the user (to maintain the user's identity information as the
loss of this information can result in the compromise of the users identity) and the Web services
which may grant access to valuable resources and information based upon the integrity of the
identity information provided by the IP.
SPML: Service Provisioning Markup Language.

Solution Assembly: Process of implementing a solution by assembling the necessary
components into a complete solution. This process often involves additional “glue” code to
integrate the assembled components.
Test Harness: Software that automates the software engineering testing process to test the
soft-ware as thoroughly as possible before using it on a real application. Trust Domain: an
administered security space in which the source and target of a request can determine and
agree whether particular sets of credentials from a source satisfy the relevant security policies
of the target. The target may defer the trust decision to a third party thus including the trusted
third party in the Trust Domain.
UBL: Universal Business Language.

UDDI: Universal Description Discovery Integration.

Web Service: Functionality provided by a service, which is exposed using the Internet (SOAP,
HTTP, WSDL, XML, TCP/IP) as the transport mechanism. Can be internally provided as part of
a suite of services or can be offered by external organizations.
Web Service for Remote Portlets: A user-facing Web Service that will provide content,
marked for display, to a portal or other aggregating Web application. This moves Web Services
out from the back-end model layer.
