Metadata enrichment

Metadata enrichment is the addition of attributes a file system does not supply. Format-aware plugins read structural details without reading contents, such as read counts in a sequencing file or codec and duration in a video. Rule-based enrichment adds fields such as project, retention class, cost center, and sensitivity signals.

Key takeaways

  • Enrichment adds attributes the file system does not record.
  • It runs automatically at index time through rules, plugins, and lookups in business systems.
  • Enriched fields let teams search and act by business meaning instead of by folder.

It means a file is described by more than the file system recorded. A basic index knows a file’s name, size, owner, and dates. An enriched record adds details such as the project it belongs to, the camera or instrument that produced it, the study or order number it relates to, or its retention class. Those added fields are what let teams search and act by business meaning instead of by folder.

Rules and plugins add fields at index time, without anyone typing them:

  • Rules can read a project code from a path and record it on every file under that path.
  • Format-aware plugins can read a file’s header and record details such as resolution or instrument settings.
  • Business system lookups can match a shared value, such as an order number, and copy related fields onto the file.

Because enrichment runs on every scan, the description stays current as files arrive.

Tagging attaches a label to a file, such as “approved” or “archive,” usually by a person or a simple rule. Enrichment adds descriptive fields, such as project, owner, or format details, usually automatically and at scale. A tag records a decision about a file, and enrichment records facts about it. Both end up in the same catalog, and both can drive search and policies.

  • Application databases, such as media asset management, lab information, or product lifecycle systems, which record the project, sample, or part a file belongs to.
  • Sidecar files saved next to the main file, which hold settings, captions, or capture details.
  • Logs and run records from instruments, render farms, vehicles, and simulations, which record when, where, and how data was produced.
  • Business systems such as project tracking, ticketing, or customer systems.
