Data sharing and synchronisation involving mobile devices has been a significant challenge to research. The methods for tracking changes and conflicts often require the involvement of a server or desktop PC with the available storage or processing power to do so, reducing the flexibility and potential of mobile device applications. This paper presents storage mechanisms for storing data on a mobile device which allow data to be related and connected and yet easily synchronised within logical structures. This data can then be synchronised with other hosts with ease. This research bases data on serialisation to allow more logical linking of PIM data among mobile data applications.
