Metadata Management
Metadata management is defining, organizing and governing the data that describes your data, such as field definitions, units, value lists and ownership.
What is Metadata Management?
Metadata management is the practice of defining, organizing and governing the data that describes your data: field names, attribute definitions, units, allowed values, taxonomies, ownership and source. In product management it keeps every product record readable and consistent, for people and for systems. Product metadata answers questions like "what does the field width mean, in which unit, and who may change it?". It differs from the product data itself (the width is 80 cm) and from SEO metadata such as meta titles, which is content shown to search engines. Metadata management is part of data governance, which also covers roles, processes and quality rules. Our guide to data governance shows how the two fit together.
Why Metadata Management matters for e-commerce
When nobody defines what a field means, teams fill it differently. One person enters weight in grams, another in kilograms, and a third puts the shipping weight in the same field. Filters break, feeds get rejected and imports overwrite good data with bad. Clear metadata, such as definitions, units, value lists and owners, lets new colleagues, suppliers and connected systems fill and read product data the same way, which matters more with every channel and language you add.
Examples of Metadata Management
- 1Field: Weight, Metadata: definition "net product weight", unit kg, two decimals, owner Product team
- 2Field: Color, Metadata: value list of 24 colors, used for filters, required for apparel
- 3Field: Description, Metadata: languages en, nl, de, source AI enrichment, last edited by user and date
- 4Field: Category, Metadata: linked to Google product taxonomy, one category per product

Common mistakes with Metadata Management
- Leaving field definitions in people's heads instead of writing them down.
- Allowing free text where a value list or unit is needed.
- Not naming an owner per field, so nobody decides when a definition changes.
- Confusing product metadata with SEO meta tags and only managing the latter.
Tips for Metadata Management
- Write a one-line definition and unit for every attribute you use in filters or feeds.
- Name one owner per field group.
- Base attribute definitions on a standard where your industry has one.
- Read the attribute standardization guide before cleaning up value lists.
