Title: Method and system for semantic metadata compression in a two-tier storage system using copy-on-write

Abstract

Example embodiments of the present invention relate to a method, a system, and a computer program product for managing metadata. The method includes determining a common characteristic of metadata entries for a plurality of files in a directory of a file system and computing a representative metadata entry for the plurality of metadata entries according to the common characteristic of the metadata entries. The plurality of metadata entries in the file system then may be represented according to the computed representative metadata entry.
