Internet commerce has created newer forms of service interactions than traditional marketplace transactions. Amazon/UKOnline, single-consumer-to-service transactions – e.g., making customer listings, doing basic look-ups and verification checks, and purchasing goods – are giving way to more distributed, pull-oriented and data streaming modes of interaction on the web. Marketplace auctions, voting, and subscription-based RSS feeds are enhancing wider spans of participants and semistructured, audio and video data in conventional transactional forms.

Current provisions for discovery are based on keyword searches through repositories. Keywords are nominated by service providers through publication and advertising features of software as a service (SaaS) functions. Details of message inputs, outputs, and methods are also captured from WSDL file scans and factored into searches.
Such discovery techniques are suitable in tightly coupled and well-scoped domains where service consumers can determine what services offer and how they can be independently utilized from search results. In other words, users are expected to know what they want before they search.

Service-oriented architecture (SOA) has gained mainstream acceptance as a strategy for consolidating and repurposing legacy applications to be combined with new applications in more dynamic environments, through self-contained, reusable, and configurable services. As fostered through the web services standards stack, services, once in place, can interoperate with other services, be composed into long-running business processes, spanning intra- and inter-organizational boundaries, and be procured through different business domains and market sectors. As web services are exposed and connected with one another, they give rise to service ecosystems.
