Oracle Enterprise Metadata Manager
The Oracle Enterprise Metadata Manager (EMM) is a product of the Oracle Corporation that provides an ISO/IEC 11179 metadata registry. Strategic nature of a metadata registry This product is significant because it is one of the first commercial products that includes a metadata registry in an application server. Registering metadata is one of the first steps in metadata publishing which in turn is one of the foundational elements of the Semantic Web. Oracle product editions EMM currently runs on the following Oracle products # Oracle Enterprise Edition ## 8.1.7 ## 9i ### Release 1 ### Release 2 # Oracle 9iAS ## Version 1.0.2.2.2 EMM is being ported to Oracle 9iAS Release 2 and 10gAS{{Update after, 2011, 04, 13 .

ISO/IEC 11179
The ISO/IEC 11179 Metadata Registry (MDR) standard is an international ISO/IEC standard for representing metadata for an organization in a metadata registry. It documents the standardization and registration of metadata to make data understandable and shareable. Intended purpose Organizations exchange data between computer systems precisely using enterprise application integration technologies. Completed transactions are often transferred to separate data warehouse and business rules systems with structures designed to support data for analysis. A de facto standard model for data integration platforms is the Common Warehouse Metamodel (CWM). Data integration is often also solved as a problem of data, rather than metadata, with the use of so-called master data. ISO/IEC 11179 claims that it is a standard for metadata-driven exchange of data in an heterogeneous environment, based on exact definitions of data.

Metadata Registry
A metadata registry is a central location in an organization where metadata definitions are stored and maintained in a controlled method. A metadata repository is the database where metadata is stored. The registry also adds relationships with related metadata types. A metadata engine collects, stores and analyzes information about data and metadata (data about data) in use within a domain. Use of metadata registries Metadata registries are used whenever data must be used consistently within an organization or group of organizations. Examples of these situations include: * Organizations that transmit data using structures such as XML, Web Services or EDI * Organizations that need consistent definitions of data across time, between databases, between organizations or between processes, for example when an organization builds a data warehouse * Organizations that are attempting to break down "silos" of information captured within applications or proprietary file formats Central ...

Metadata Publishing
Metadata publishing is the process of making metadata data elements available to external users, both people and machines using a formal review process and a commitment to change control processes. Metadata publishing is the foundation upon which advanced distributed computing functions are being built. But like building foundations, care must be taken in metadata publishing systems to ensure the structural integrity of the systems built on top of them. Definition of metadata publishing Published metadata has the following characteristics: # Metadata structures available to the general public on a public web site or by a download # There is a documented review and approval process for adding or updating data elements to the system # New releases are made available without disturbing prior versions # A publishing organization that makes a commitment to change control process Benefits of metadata publishing When classifying benefits of metadata publishing two groups are usually cons ...

Oracle Metadata
Oracle Database provides information about all of the tables, views, columns, and procedures in a database. This information about information is known as metadata. It is stored in two locations: data dictionary tables (accessed via built-in views) and a metadata registry. Other relational database management systems support an ANSI-standard equivalent called information schema. Views for metadata The total number of these views depends on the Oracle version, but is in a 1000 range. The main built-in views accessing Oracle RDBMS data dictionary tables are few, and are as follows: * ALL_OBJECTS – list of all objects in the current database that are accessible to the current user; * ALL_TABLES – list of all tables in the current database that are accessible to the current user; * ALL_VIEWS – list of all views in the current database that are accessible to the current user; * ALL_TAB_COLUMNS – list of all columns in the database that are accessible to the current user; * AL ...
