About the Metadata Management Tool
The MMT is a web-based user interface to the NASA EOSDIS Common Metadata Repository (CMR). The MMT allows metadata authors to create and update CMR metadata records by importing XML or by using a data entry form based on the metadata fields in the CMR Unified Metadata Model (UMM). Metadata authors may also publish, view, delete, and manage revisions of CMR metadata records using the MMT.
