 Business Case for Metadata Minimize
Why Do Metadata?

Metadata helps you do your job. Looking for a geospatial dataset? Search engines, such as the national Geodata catalog at, read metadata.

Did you find a dataset but you are not clear about what it represents? Read the descriptions, definitions and process steps in the metadata.

Do you offer data for download and get repeated questions from users? Write the answer once—in the metadata.

Use Metadata to Support …

Data Management requirements to:
  • re-use or adapt a dataset to a new project
  • capture and archive a dataset for “before-and-after” comparisons and future reference
  • assess the age and character of data holdings to determine which data should be retained, updated, or deleted
  • be accountable for the data—state what you know (or don’t know) about the data
Project Management requirements to:
  • plan and document the data types and content needed to support a project
  • monitor data development by regular review of process steps—write and update metadata as you go
  • document a common set of data fields and definitions for all project participants
  • clarify what contractors produced—require robust metadata that describes the lineage and content

As a GIS professional, you can store a lot of knowledge in your head, but what happens in your absence? Undocumented data lose their value. A new user cannot trust datasets that are not fully described. Someone may not find the earlier dataset or not be confident in a found file, and waste time and money in duplication of effort. Writing and editing metadata may seem time consuming, but metadata pays off for you and other GIS users.

See these Federal Geographic Data Committee (FGDC) publications for more information about the use and value of metadata:
