What comes to mind when you hear the word “metadata?” Is itintimidating? Do metadatists and catalogers explain the term adequately? While this articleby no means captures all there is about metadata, it is intended to provide librarians with a basic understanding of what is involved in metadatawork.

Rushes footage are considered as cheap gold mine with the potential for reuse in broadcasting and filmmaking industries. However, it is difficult to mine the "gold" from the rushes since usually only minimum metadata is available. This paper focuses on the structuring and indexing of the rushes to facilitate mining and retrieval of "gold". We present a new approach for rushes structuring and indexing based on motion feature. We model the problem by a two-level Hierarchical Hidden Markov Model (HHMM). The HHMM, on one hand, represents the semantic concepts in its higher level to provide simultaneous structuring and indexing, on …
