Storing SCA Metadata in the Oracle Metadata Services Repository by Nicolás Fonnegra Martinez and Markus Lohn

The advantages of using the Oracle Metadata Services Repository as a central storage for the metadata.
SCA
has been available since the release of the Oracle SOA Suite 11g. This
technology combines and orchestrates several SOA components inside an
SCA composite, making design, development, deployment, and maintenance
easier. SCA development is metadata-driven, meaning that metadata
artifacts, such as Web Services Description Language (WSDL), XML Schema
Definition (XSD), XML, others, define the composite's behavior.
With
the increased number of composites and the dependencies among them, it
became necessary to manage all the metadata in an adequate way. This
article will address the advantages of using the Oracle Metadata
Services (MDS) repository as a central storage for the metadata. The MDS
repository is a central part of the Oracle Fusion Middleware landscape,
managing the metadata for several technologies, such as Oracle
Application Development Framework (Oracle ADF), Oracle WebCenter, and
the Oracle SOA Suite. This article is divided into three parts.
The
first part provides an overview of SCA and MDS. The second part
describes some MDS tasks that help in the management of the SCA metadata
files inside the repository. The third part shows how to develop SCA
composites in combination with an MDS repository. Read the full article here.
