Abstract
Service discovery is the matching of the needs of a service requestor with the offerings of service providers.
It is currently functionally focused (i.e. concentrating on what the service does), and occurs in what can only
be considered a volatile and heterogeneous environment. Bring to that equation the area of web services,
with its various specifications, and service requestors are no better equipped to efficiently discover both
traditional and web services. We offer an approach to describing the non-functional properties of services
(including payment, price, availability, obligations, rights, security, trust, quality, discounts, and penalties)
that does not differentiate between traditional and web services. It attempts to describe the non-functional
properties in a domain independent manner that is motivated by the desire to provide sophisticated service
discovery, service selection, automated service negotiation and dynamic service substitution.
