An Introduction To Metadata Repositories (MDR)

A metadata repository is a database that manages metadata. Generally, metadata is a set of facts and figures that add meaning to other data. The purpose of a metadata repository is to offer steady and authentic means of data access. Ideally, data in an archive should be up-to-date, integrated, historical, and universal.

A metadata repository must have accessible current and past data. The integration enables all organization’s metadata to be incorporated, covering all company fields. On the other hand, universality allows data storage in generic forms rather than specific ones. It ensures that your data doesn’t change if the database shifts from one platform to another. To further explain, this article covers the basic things you need to know about metadata repositories:  

Factors To Consider When Choosing A Metadata Repository

Sometimes, choosing and implementing new systems and software in your organization can be challenging. It’s because you’d want a system that doesn’t interfere with your normal business operations. For this reason, consider learning about metadata automation to get an insight into the challenges you’re likely to face and how to overcome them. Here are some factors for your consideration:     

  • Integration: A metadata repository should be at the core of your business. Therefore, it must work well with other systems and databases to be more effective and augment data quality.
  • Governance: You need to manage your metadata through your system life cycle; failure to do so can make your data invalid. It can result in inappropriate data collection or processing and poor data quality that doesn’t meet your requirements.
  • Visibility: A metadata repository should indicate how and where your metadata is used and how frequently you use it. Moreover, it should show any change in content and the cause of the changes, enabling you to make more enlightened decisions about any upgrades.
  • Collaboration: Collaboration is a crucial feature in any organization. Your metadata repository should allow your workers to work together more easily from different locations and on the same platform. 

Metadata Repository Design

Metadata repositories store data in the following categories:

  • Physical characteristics specify the genesis and physical location of the data
  • Ownership indicates the data and application owner
  • Rules and policies describe data security, purity, connection, and timelines
  • Descriptive characteristics outline names, types, lengths, and information explaining organizational data or processes

Typical Designs

The metadata repository can adopt any of the following designs:

  • Centralized design: This design stores all data in your organization in one database. With this, there’s easy data management, enhanced data integrity, and reduced data redundancy. However, bottlenecks can occur as a result of increased traffic. Also, several people might have limited access simultaneously as only one copy of it is maintained in a single location.
  • Decentralized: In this system, data is stored in various databases, perhaps categorized according to the departments of your organization. The databases are independent and aren’t connected through a communication network.
  • Distributed: It utilizes a decentralized design, but the only difference is that the metadata remains in its initial application. It provides excellent metadata quality since users can obtain the most recent information about specific data.

Functions Of Metadata Repository

A metadata repository provides a platform to handle and organize data efficiently for quick retrieval and use. Typically, the metadata repository:

  • Categorize schemes to coordinate efforts and identity for vital metadata management.
  • Demonstrates the state of metadata frameworks across the company, including how various systematic occurrences interconnect.
  • Maintains the essential metadata features organized by use or function to allow clearly expressed responsibilities and relationships that increase the accuracy of data used in decision-making.
  • It serves as a frame of reference to express information technology (IT) needs and restrictions between IT services and data users.

Metadata Repository Services

Appropriate development of metadata repository supports a wide range of essential services. Generally, the structural and organizational elements of the metadata repository allow the display of data in meta-models that foster several vital business services:

  • General access to web applications
  • Metadata model contrast and versioning
  • Converting metadata models into conventional meta-models
  • Collaboration facilitation
  • Totaling and stitching metadata models from different sources
  • Access management for security and role focus simpleness
  • Export of metadata models into various formats
  • Control reports and inquiries on repository content

Benefits Of Using Metadata Repositories

Metadata repositories enable all your organization’s data to be in one integrated place. It uses a universal data model to combine various applications and programs into a single format. In addition to that, metadata repositories help you in:

  • Making critical business decisions
  • Integrating metadata across your company
  • Building relations between different metadata types and disparate systems
  • Validating structures by overlapping models
  • Interacting with reference data
  • Discovering deviations at the data structure level
  • Linking view to master data
  • Controlling version changes at the structure level
  • Automatic synchronizing of several approved metadata source systems


A metadata repository is the best way to ensure storage consistency in your organization. With it, you can store your data in a database and reference it by application or pages, thus making data easy to access and retrieve. However, before incorporating a metadata repository, ensure you get an insight into its related dynamics. This article has introduced the basics. Master them, and then explore more information.
