Often described as data about data, metadata is a foundational element used to transform data into an enterprise-wide asset. Metadata helps understand the data behind it, metadata reflects how data is used and is key to supporting data governance initiatives, regulatory compliance demands and data management processes.
Metadata is critical to data management because it provides essential details about an organization’s data assets —what is that data, when the data was created, where it resides, how it’s been altered, who has access and who owns it. Simply defined, metadata is the summary and the description about your data that is used to classify, organize, label and understand data, making sorting and searching for data much easier.
Without metadata, companies can’t manage the huge amounts of data created and collected across an enterprise. They need metadata to understand and effectively deploy information resources to support different business processes and enable advanced analytics.
However, different departments have various metadata perspectives on how to organize and interpret metadata.
Defining Diverging Metadata Perspectives
Metadata provides a comprehensive understanding of where data resides in an organization and how it is deployed. To ensure all data users understand organizational metadata, businesses must collect, arrange and manage metadata from three different perspectives – physical, logical and conceptual.
Once an organization identifies these three types of metadata, they can empower the business to create a metadata glossary and make it readily available to all users.
Building a Metadata Glossary
A metadata glossary provides transparency into data assets for both business and technical users. Building the glossary starts with an enterprise-wide data governance strategy that emphasizes data quality.
A comprehensive data governance program helps encourage communication between data owners, data stewards and users to cultivate a collaborative approach for establishing common data descriptions. When everyone works together to interpret and document metadata, organizations can institute a mutual understanding of data assets, minimizing any confusion business users face when looking through the metadata glossary. By automating and tracking these processes, alerts are generated when a data element falls out of compliance.
With full participation across the enterprise, data governance delivers complete transparency into an organization’s data supply chain so business users can easily define, measure, track and manage their data assets.
Data governance also provides accountability for individual data assets. By establishing clear lines of responsibility, companies ensure that metadata is always consistent and precise. Data integrity components can then connect metadata descriptors and data quality scores to ensure data remains accurate, reliable, trustworthy and fit for use.
In addition, data governance programs help to keep pace with the ever-growing supply and demand for data. Today, machine learning capabilities embedded into a data governance program automates the capture and curation of metadata, removing some manual efforts that save businesses time and money.
Once metadata has been defined within the context of a greater data governance program, the final critical step is to identify a metadata management tool to help capture, curate, evaluate, and store metadata. This should be an automated process to facilitate data tracking and accountability. Of course this can be done using spreadsheets, keeping the information up-to-date will cause major headaches. Capturing, publishing and updating metadata on every current and future data project will yield decreased time to insights, helping the business make better informed business decisions, faster.
By understanding and evaluating metadata from various perspectives, together with an integrated data governance program, organizations can successfully build a comprehensive metadata glossary, secure a metadata management solution and empower all data users to take advantage of trustworthy data.
