KEA metadata guide
Introduction
KEA metadata provides standardized information for describing functional genomics studies, encompassing overall study design, protocols for sample collection and data processing, and technical details of experimental factors. The metadata framework ensures that each dataset is described in a consistent and reproducible manner, facilitating data sharing and reuse.
Metadata structure
KEA metadata is organized into five major parts, each describing a different level of information in the experimental workflow.
Part 1
Submission Type
Defines the submission category (HTS or Microarray), data type, completeness, and release date.
Part 2
Study Information
Describes the overall study — including title, abstract, contributors, experimental type, and design.
Part 3
Protocols
Provides detailed descriptions of experimental protocols used for sample preparation and data processing.
Part 4
Sample & Experimental Details
Captures experimental metadata, including molecule type and other experimental factors.
Part 5
Result Files
Lists and categorizes all uploaded data files
Metadata by submission type
KEA supports two major types of functional genomics experiments, each with tailored metadata fields:
1. High-throughput sequencing (HTS)
Key metadata fields:
Library name and Sample details
Material type (e.g., polyA RNA, genomic DNA)
Factor value (e.g., Disease, Cell type, Compound, Time)
Description
Platform ID (e.g., GPL6805, GPL30172)
2. Microarray
Key metadata fields:
Detailed sample title
Source name
Molecule (e.g., polyA RNA, genomic DNA)
Label (e.g., biotin, Cy3 and Cy5)
Description
Platform ID (e.g., GPL6805, GPL30172)
Factor value (e.g., Disease, Cell type, Compound, Time)
Standard registration form
