2004), the Web services offer language (WSOL)
(Tosic, Pagurek, & Patel, 2003), WS-policy (Hondo & Kaler, 2002); extensions
for UDDI, such as UDDIe project (Shaikhali et al., 2003), UX system (Zhou et al.,
2004), and WS-QoS framework (Tian et al., 2004); ontology level solutions like
Web service modeling ontology (WSMO) (Lausen et al., 2005).
The following sections will describe these research works. We divide them into
non-ontology-based works and ontology-related works.
QoS-Related Service Description without Ontology Definition
QDL is the description language for the QuO framework. Through aspect-oriented
approach, an application can be decomposed into functional components and aspects,
where different aspects can be programmed in different languages. QuO framework
extends the CORBA functional interface definition language (IDL) with the QDL
language, which consists of three sublanguages: (1) the contract description language
(CDL), (2) the structure description language (SDL), and (3) the resource description
