What is a Taxonomy?

A taxonomy is a standards-based classification scheme used to organize electronic content.

How are Taxonomies used?

Taxonomies can improve many aspects of on line information management.

They can be used to:

• make search more robust
• facilitate data interoperability
• allow business analysis across content in disparate repositories
• support records management for long term archiving
• enable role-based content delivery for portals
• kick off work flows for process based information transactions

How is the NASA Taxonomy used?

The NASA taxonomy provides first steps towards the unification of the NASA information space by documenting a high level set of terms that can be used for mapping together varying data structures. Reconciliation of terms and topics is essential to understanding NASA discoveries in a larger context. Find out more in our Resources section.
