Metadata與OAI-PMH在新聞數位典藏之整合應用 Integrated Application of Metadata and OAI-PMH to Digital News Archive

Abstract

本文探討所建置的台灣棒球新聞資料庫與數位典藏聯合目錄的後設資料整合問題。首先，我們設計一個後設資料轉換系統，可轉出DC、NITF、RSS和DAC 等四種國內外普遍盛行之後設資料格式；本系統不僅能支援後設資料自動轉換，也能衍生出RSS訂閱和聯合目錄大批匯出等應用。其次，基於OAI-PMH架 構，我們以此新聞資料庫作為Repository，建置符合OAI-PMH協定之Data Provider。它可供包含數位典藏聯合目錄在內的任何Service Provider查詢，然後進行命令集剖析，再以特定的後設資料格式回應資料集給Service Provider。就實驗結果而言，本系統可有效促進數位化新聞的傳播與分享。This paper studies the metadata integration problem between the Taiwan Baseball News Database and the Union Catalog of National Digital Archives Program. First, we design a metadata transformation system which can transform the news articles to four popular metadata formats: DC, NITF, RSS and DAC. The system not only supports metadata transformation but also RSS subscription and batch exportation for Union Catalog. Secondly, based on the OAI-PMH architecture, the digital news archives plays a role as Repository, and then we extend the system to be a Data Provider. It can be queried by any Service Provider, parse the Verbs, and then respond the Record Sets to the Service Provider with certain metadata format. As a result, the digital news can be delivered more efficient.
