台灣政府開放資料之詮釋資料建置探討

Taiwan government launched its official open data portal (data.gov.tw) in April 2013. However, one of the challenges of open government data is to help users understand and retrieve datasets. Particularly, this challenge results from the lack of appropriate metadata schema. Currently, there is very limited research focusing on metadata of open government data. Therefore, the purpose of this research is the construction of metadata schema for open government data in Taiwan, and several frameworks of metadata construction and related influential factors are also taken into consideration in this development process. There are four contributions in this research. First, metadata schemas of different countries, including the U.S., the British, and Canada, are analyzed and compared. Second, various steps and influential factors of metadata construction are discussed to form an integrated perspective guiding the research. Third, a specific metadata schema for open government data is proposed for Taiwan government. Lastly, practical implications are also discussed to provide insights to practitioners.我國政府近年來積極推行政府開放資料，並於2013年將資料開放平台上線提供公眾使用。現階段開放資料釋出的主要障礙之一，即是使用者如何取用到合適的資料集。然目前開放資料的詮釋資料文獻較為有限，因此本研究以開放資料為研究場域，初步探討詮釋資料的類型與建構歷程，並綜整他國開放資料之詮釋資料架構，提出初始研究架構。後續本研究透過訪談方式取得實證資料，從開放資料承辦人員的角度分析調整初始研究架構，整合之最終結果為31個詮釋資料建議欄位。此外，本研究亦針對詮釋資料欄位設計細節與相關實務提出建議，可作為我國政府推行開放資料的參考，以期建立一套我國政府開放資料所專屬之詮釋資料架構，協助開放資料的推廣與取用。
