檔案編碼描述格式 EAD
<評定> <appraisal> Appraisal Information
定義
有關決定檔案價值的程序，如此記錄的處理方式會以其行政、法定、財政用途；其證據、內在、資訊價值；其編排、狀況；及和其他記錄之間的關係為依據。
EAD 1.0版中，<評定>是<行政資訊>（<admininfo>）下屬所的子元素，但元素<附屬描述資料>在EAD2002裡已被限用（見附錄二）。新的元素<描述群組>（<descgrp>）可以用來組織任何<描述識別>（<did>）等級的元素（<附屬成分描述>（<dsc>）除外），可做為一群被描述標目的封包元素。將EAD V1.0轉換到2002版時， 原<行政資訊>的封包元素，可以用<描述群組>取代。
此元素相當於ISAD(G)資料元素3.3.2與MARC的583段。

<評定>
<段落>The records of the Mid-Ocean Dynamics Experiment came to the Institute Archives in two accessions in 1980 and 1982. During processing the collection was reduced from fifteen cubic feet to four by discarding duplicate materials, financial records, and publications not authored by MODE participants. Forty charts and six inches of raw data presented the primary appraisal issues. The raw data consisted of bulletins and reports referring to float positions, moorings, isotherms, geostrophic velocity calculations, ships' summaries, and work proposed and work carried out during the MODE-I experiment.
As this raw data was recapitulated in weekly <title render="underline">MODE Hot Line Bulletins</title>, only a sampling was retained in the collection. Also discarded were ten charts for which there were no descriptions of indicated data points, nor were dates or test site locations provided.</段落>
<段落>Six inches of materials pertaining to the POLYMODE project, 1973-1980, were added to the Institute Archives POLYMODE collection.</段落>
<段落>The appraisal of this collection was carried out in consultation with Robert
Heinmiller, a research associate at Woods Hole Oceanographic Institution during MODE.</段落></評定>
