台灣政府開放資料之詮釋資料建置探討 / The Construction of Metadata for Open Government Data in Taiwan

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. La
