Managing and Reusing Artifacts Using MDS (and a Common Project)

SOA Suite provides a central store for shared artifacts that can be accessed at design time from JDeveloper and at run time from deployed SOA composite applications. This central store, the MDS repository, along with the Metadata Services on top of it, helps to organize reuse of cross-application artifacts such as canonical data model definitions, SOA composite templates and business event definitions. Note that the MDS repository is an intrinsic part of the SOA Suite run-time environment, not something that you need to install separately and additionally. However, also note that during development, the JDeveloper IDE can make use of a local, file system–based MDS repository.

Service Bus does not interact with MDS – neither at runtime nor at design time, except for the ability to import objects from and export objects to the design time MDS. Working with common, shared artifacts in Service Bus projects is typically done using a single, generic, shared project that holds these artifacts.
