本文旨在針對數位博物館Metadata進行探討，共採取了文獻探討、比較分析與個案研究三種研究方法，分別就數位博物館計畫Metadata相關名詞暨標準的發展與應用現況進行研議、標準對照與分析，以及國家典藏數位計晝的個案研究。本研究發現：(l) 數位博物館計童Metadata發展的理念與重心各有不同，但實際應用上存有互補性；(2) 會有相對應的相關Metadata格式、詞彙典、資訊模式為輔，讓Metadata的應用更臻於完善；(3) Metadata提供的資源描述類目在詳簡程度與深度結構上具有相當大的差異，實際應用時可視需求而有所選擇。此外，以國家典藏數位計劃為個案研究，也提出四項研究發現：(1) 數位典藏品metadata面臨的環境與挑戰；(2) 建立metadata生命週期作業模式；(3) 發展metadata內涵分析的方法論；(4) 建構metadata互通層次架構。最後，本文針對metadata的採用標準、特質、面向、層次、品質保證與不同metadata間關係等六大議題提出建議。

　　　　　This paper aims to take a serious study on related Metadata standards and issues of the digital museum projects by deploying three research methodologies: literature review, comparative study, and case study. This paper is composed by four parts as follows: related terminologies and coverage, typology of current Metadata development, research finding based on a comparison of four standards, and a case study of the Digital Archives Project in Taiwan. This paper raises three findings: (1) A variety of Metadata standards are developed for different purposes, and complementary to each other; (2) In order to achieve functionality optimization of Metadata, related standards are designed as dependent mechanisms, like union list, thesaurus, data model; (3) In terms of comprehensiveness and structure, disparity exists amongst a wide of Metadata standards. In practice this substantial customized phenomenon is reasonable for implementation of each digital museum project. This paper also presents four findings for a case study as follows: (1) challenging issues of Metadata implementation in digital museum project: (2) constructing a Metadata lifecycle model, (3) developing content analysis methodology; (4) building up the Metadata interoperability levels. Finally, this paper addresses four issues and suggestions as conclusion: adoption of Metadata standards, characteristics, facets, levels, quality assurance, and relationships of Metadata.
