Metadata helps users organize and retrieve assets, but not all metadata is equally useful. The way people in an organization naturally search is specific to that organization. Understanding the two types, embedded and custom, and what each is good for, is what lets you manage assets effectively.
What is embedded metadata?
Embedded metadata, or "baked-in" metadata, is automatically attached to a file by the software that produced it. It usually describes technical details: format, resolution, creation date. Take a photo on your phone and it carries the location, the date and time, and often facial grouping, all of which make it easier to find. A digital camera does the same with resolution, size, and exposure.
Its strengths: it cannot be separated from the file, so it survives migration and copying, and it is readable by a wide range of software. Its weakness: it usually is not the information people search by at an organizational level. A channel manager in marketing is not hunting by resolution or file size; they need the subject, where and when it was shot, the usage rights, and the creator. Embedded metadata alone is not descriptive enough to organize a large library, because it does not speak the organization's language.
What is custom metadata?
Custom metadata is information an end-user adds to an asset after it is created. Unlike embedded metadata it is not automatic; it can include keywords, descriptions, copyright terms, and the channels an asset is approved for. As the name says, it is custom to the organization, its assets, its users, and its DAM strategy.
Its strength is exactly that descriptiveness. Its weaknesses are two. First, because users can add almost anything, ad hoc tagging produces disorganized results that need cleanup later, which is why a custom metadata taxonomy is essential. Second, it has to be added after creation, often manually, which takes time, especially when applied directly to assets rather than inside a DAM platform.
Use both
Embedded and custom metadata are both essential. Embedded provides durable technical detail; custom adds the descriptive, organization-specific information your team searches by. Combine them and assets become quick to locate and retrieve. This article adapts a piece from the Stacks blog.
Key takeaways
- Embedded metadata is automatic, technical, and travels with the file.
- Custom metadata is added by people and matches how your organization searches.
- Embedded alone cannot organize a large library; custom alone gets messy without a taxonomy.
- Combining the two is what makes a library genuinely findable.
