ii. a service interface level corresponding to a service interface of the service component;

iii. a service interface compatibility level corresponding to compatibility of the service component with one or more predefined service interfaces;

iv. a configuration level corresponding to one or more components used for external configuration of the service component;

v. a business context level corresponding to a business context associated with the service component;

vi. a quality of service level corresponding to a quality of service provided by the service component; and

vii. a software component level corresponding to a software implementation component of the service component; and

b. integrating each of the plurality of specification levels according to a predefined hierarchy, the version identifier comprising the integrated specification levels;

c. registering the service component in a service registry based on the version identifier, the service registry comprising a plurality of version identifiers corresponding to a plurality of service components; and

d. storing the service component in a repository based on the registration, the repository comprising the plurality of service components.

2. The method of claim 1 further comprising identifying a set of service components from the plurality of service components, the set of service components being identified based on one or more user requirements and the plurality of version identifiers.

3. The method of claim 1 , wherein the version identifier is defined by a user.

4. A non-transitory system for defining a version identifier of one or more service components, the system comprising:

a. a determining module, the determining module configured for determining a plurality of specification levels corresponding to a service component, the service component being one of the one or more service components, the plurality of specification levels comprising:

i. a business functionality level corresponding to a business functionality associated with the service component;

ii. a service interface level corresponding to a service interface of the service component;

iii. a service interface compatibility level corresponding to compatibility of the service component with one or more predefined service interfaces;

iv. a configuration level corresponding to one or more components used for external configuration of the service component;

v. a business context level corresponding to a business context associated with the service component;

vi. a quality of service level corresponding to a quality of service provided by the service component; and

vii. a software component level corresponding to a software implementation component of the service component; and

b. an integrating module, the integrating module configured for integrating each of the plurality of specification levels according to a predefined hierarchy, the version identifier comprising the integrated specification levels;

c. a registering module, the registering module configured for registering the service component in a service registry based on the version identifier, the service registry comprising a plurality of version identifiers corresponding to a plurality of service components; and

d. a storing module, the storing module configured for storing the service component in a repository based on the registration, the repository comprising the plurality of service components.

5. The non-transitory system of claim 4 further comprising an identification module, the identification module configured for identifying a set of service components from the plurality of service components, the set of service components being identified based on one or more user requirements and the plurality of version identifiers.

6. The non-transitory system of claim 4 , wherein the version identifier is defined by a user.

7. A non-transitory computer program product for use with a stored program computer, the computer program product comprising a computer usable medium having a computer readable program code embodied therein for defining a version identifier of a service component, the computer readable program code performing:

a. determining a plurality of specification levels corresponding to the service component, the plurality of specification levels comprising:

i. a business functionality level corresponding to a business functionality associated with the service component;

ii. a service interface level corresponding to a service interface of the service component;

iii. a service interface compatibility level corresponding to compatibility of the service component with one or more predefined service interfaces;

iv. a configuration level corresponding to one or more components used for external configuration of the service component;

v. a business context level corresponding to a business context associated with the service component;

vi. a quality of service level corresponding to a quality of service provided by the service component; and

vii. a software component level corresponding to a software implementation component of the service component; and

b. integrating each of the plurality of specification levels according to a predefined hierarchy, the version identifier comprising the integrated specification levels;

c. registering the service component in a service registry based on the version identifier, the service registry comprising a plurality of version identifiers corresponding to a plurality of service components; and

d. storing the service component in a repository based on the registration, the repository comprising the plurality of service components.

8. The non-transitory computer program product of claim 7 , wherein the computer readable program code further performs identifying a set of service components from the plurality of service components, the set of service components being identified based on one or more user requirements and the plurality of version identifiers.
