'''Services Directory Services:''' This directory lists all actions on Metadata as it relates to the entire Metadata lifecycle, including exploitation of metadata. This is a list of metadata-related functions, such as requesting a job or data lineage service, assigning a term to a selected Metadata asset or object, requesting an impact analysis service, and so on.

'''Data Directory Services:''' Part of the Metadata is represented in relational format. For instance, a relational format might be a business term, the semantic of the term, or related IT objects such database tables, indexes, and so on. Another example is the property of a data file or specifications of a BI report.

'''Content Directory Services:''' Another part of the Metadata is represented in unstructured (content) format. For instance, a transformation job is described in terms of the property of the job, job design information, and images that depict the transformation job for a UI-based tool.

'''Metadata Indexing Services:''' Performing simple or advanced searches of Metadata and identifying the right Metadata needs to be done in the context of a specific business or technical task. Indexing the Metadata is done to facilitate this search of the entire Metadata repository at a reasonable speed. These services enable the exploration of Metadata and the generation of graphical or report views of Metadata asset relationships.

'''Translation Services:''' Generating or importing Metadata from a diverse set of sources and making this Metadata available for other services requires the translation of Metadata from proprietary formats to unified standardized Metadata formats, such as using the Common Warehouse Metamodel (CWM) of the Object Management Group (OMG).

'''Retrieval Services:''' These services enable you to browse and retrieve the contents and services of the Metadata Management Component and obtain information that can be useful to you when transforming information, improving quality of source data, performing data modelling tasks, or developing applications.

'''Navigation Services:''' Metadata Navigation Services are needed to understand available Metadata of a specific scope of interest or in the context of a specific use case scenario. They enable navigation through the diverse types of Metadata to fulfill a defined user need. For example, Metadata can be used to get the right seach criteria for an enterprise-wide search definition.

'''Metadata Bridges Services:''' These services enable the import and export of Metadata from heterogeneous sources such as physical database models from a heterogeneous set of databases or to export Metadata into Excel spreadsheets or PDF documents.

'''Metadata Tools Interface Services:''' The Metadata Tools Interface Services enable Metadata modelling tools to read, modify, and write data to the Metadata repository.

'''Metadata Models Services:''' These services help establish Metadata models for a defined set of problems, tasks, use case scenarios, or business processes. These include the analysis, design, and build process to generate and make available Metadata models for exploitation of Metadata by other tools and tasks.
