Scientific Metadata

This entry is a collection of resources for SCEC researchers defining metadata for their scientific data.

Type of Metadata

There are three main types of metadata:

• Structural: Defines the metadata elements that need to be collected; labels like title, author, date created, subject, purpose, etc. Defining these structural elements is typically based on a mix of organizational and system needs, along with standard schemas like Dublin Core.
• Administrative: Often created automatically when content is entered into the CMS, these values are used to manage the content. Administrative metadata includes things like date created or author. They can sometimes include sub-elements about rights-management or preservation.
• Descriptive: These values describe aspects specific to each content component, like title, subject, audience, and/or purpose.
