With the pervasion of digital technology and the Internet, artists today can create artwork by programming and inputting external data. The subject of this paper, open database art (ODA), is one such type of artwork. Open database artwork, unlike other artwork, does not consist of fixed, preset, and stable content, because it is made by retrieving external data in different sociocultural contexts or by participants’ contributions, and the retrieved data is combined to form content. This type of artwork reflects both the application of database technology and the tendency toward collective creation in the digital age. With the continual input of external data, open database artworks create moving content, changing visual appearance, and overarching relationships. These characteristics of ODA result in a dynamic relationship between the external data and the open database artwork, the transformation of the meaning of the external data, and the reconfiguration of the artwork. Four conclusions can be drawn from this study: (1) The continual open input of content is the main concept from the artist. The most characteristic approach of ODA is to involve external texts and viewer participation. (2) To better address the creation of ODA, the intertextuality in and between texts must be considered. (3) Along with the continual open input of content, a changing visual appearance, a moving textual relationship, the transformation of the meaning of the external data, and the reconfiguration of the artwork are also produced. (4) ODA is an ongoing event of art praxis. The artwork itself is a continual process, not a fixed object. Therefore, ODA must be understood through its developmental process and its particular historical context.
