ment it. From the other hand, applying light
weight semantics in this model will reduce
the complexity existing in Semantic SOA.
2. Reusability: The high ability of reusing
the functionality in this model allows each
component to be considered as a standalone
system.
3. Generating Dynamic Workflows: In the pro-
cess of composing a new service that does not
exist in the directory, a dynamic workflow
will be created in order to produce the new
service, and based on the concepts that are
The main added values from this model over
the existing related work can be summarized as
follows:
1. Light Weight Semantic Solution: From one
hand, the problems of SOA that occur at
both discovery and invocation phases can
be solved by using the proposed model and
the reference architecture that will imple-
