Planning and Implementing a Metadata Management Specialist Exam
Drew Kennedy opens the webinar and mentions the progress made on building the Metadata Management Specialist exam. He shares that this session will be a test run for some of the content. Drew encourages everyone to ask questions.
Understanding the Role of Data Manager in Metadata Management
The Data Manager's role for Metadata involves providing content, context, and structure information about data to make it easier to find, understand, use, and manage. This includes specific details such as the data source, purpose, quality, content, structure, format, stewardship, business rules, and classification.
The Metadata program encompasses considerations such as data ownership, retention periods, usage, confidentiality, and compliance with naming standards, security, and privacy regulations.
Deep diving into these areas is essential for a comprehensive understanding of Metadata Management.
The Historical and Modern Context of Metadata
The practice of Metadata dates to the 3rd century BC with the libraries of Alexandria and Egypt, where the chief librarian, Callimachus, organised and catalogued the contents of the libraries using a system called “a Pinakis.”
This system included comprehensive coverage of every scroll in the library, subject-based classification, an index of authors, and detailed descriptions of the scrolls. In modern times, the Clementine Library in Prague, founded in 1857, houses around 20 million books with a comprehensive catalogue.
Presently, the importance of Metadata extends to e-commerce platforms like Amazon and Temu, where comprehensive product Metadata is crucial for business success. A lack of comprehensive Metadata can deter potential customers.
Metadata in Social Media and Music Streaming Platforms
We encounter experience Metadata in various areas of our lives every day. Social media platforms like Facebook and Instagram provide Metadata such as posting date, author, location, hashtags, comments, and likes.
Statistical data for countries like Stats SA in South Africa also offers comprehensive descriptive, structural, administrative, and support information. Music streaming platforms like Spotify and Apple Music also utilise Metadata for artist, album title, song, genre, and lyrics.
Similarly, platforms like Netflix and YouTube use Metadata to categorise and organise content.
Metadata in Modern Data Management
Metadata is not just a component but the backbone of modern Data Management. It is instrumental in organising and understanding data across various domains and industries.
Its ability to identify and distinguish different data elements within an organisation makes it easier to search, browse, and retrieve information from large data lakes and diverse data repositories.
Additionally, Metadata provides context and additional information about the data, aiding in proper storage, access, maintenance, categorisation for security and privacy, and sharing across organisations.
It also underpins Governance, Reference Data, Architecture, modelling, Data Quality, security, warehouse, and analytics. However, managing Metadata is a complex and extensive task that requires broad expertise and significant responsibility.
Essential Skills and Experience for a Data Manager
For a Data Manager, expertise in Metadata Management is not just a requirement but a necessity. This includes developing and implementing Metadata standards, policies, procedures, strategy, and road map.
It also demands a deep understanding of Data Management, Data Analysis, Data Engineering, Data Architecture, and Data Modelling. Data Governance skills and industry knowledge of the domain or industry where the organisation operates, including understanding industry-specific jargon, are also important.
Connecting with business stakeholders and understanding their needs through experience in business intelligence and data analysis is beneficial for delivering substantial value.

Data Governance and Management in Metadata Management
Drew emphasises the importance of defining Metadata standards and ensuring the quality of collected Metadata. Collaborating with the Data Governance team is imperative to establish and enforce Governance principles and policies.
Addressing the importance of managing the Metadata lifecycle ensures data privacy and security compliance?and supports reports on Data Quality, compliance, and Metadata usage.
Drew underscores the role of Data Stewards, Data Owners, and Business Analysts in capturing and updating business terms in the Business Glossary and the Data Catalogue.
He then highlights the potential for quick development of these processes using Metadata tools with strong reporting capabilities and structured databases.
Data Stewardship in Metadata Management
The challenge with Metadata lies in merging technical and business sources, such as data models, dictionaries, and quality Metadata, into a cohesive ownership model. While Data Stewards will be involved in managing glossaries and business Metadata, it's essential to recognise the technical sources contributing to the overall Metadata landscape.
Business collaboration is crucial in leveraging critical data elements and terminology to build a comprehensive glossary, linking it to physical Data Dictionaries through AI tools. This collaborative approach ensures that business terminology and technical Metadata are effectively integrated to drive the Data Catalogue.
Drew discusses the complex nature of Metadata Management within a business context. He emphasises the need for clear ownership and stewardship of different data elements. Drew shares the challenges of ensuring buy-in and commitment to capturing Metadata?and the wide-ranging responsibilities of various data owners and stewards across different departments.
A conversation then delves into the intricacies of Metadata requirements, stakeholder involvement, and the interconnected nature of data ownership and Management, using an example of a furniture retailer's customer data to illustrate the diverse responsibilities distributed among multiple teams.
Data Management and Metadata Management Challenges
Many organisations are facing challenges with managing and utilising streaming data effectively. As more and more data is being streamed into databases without proper control, there is a lack of understanding of its contents.
