Abstract.A preliminary framework, termed as DL2Go, that enables editable and portable personal digital libraries is presented. For mobile offline users of digital libraries, DL2Go can: (1) package digital libraries into mobile storage devices such as flash drives, along with needed application softwares (e.g., wiki and DBMS), (2) (de-)compress contents of digital libraries to address storage constraints of mobile users when needed, (3) enables users to add, delete, and update entities of digital libraries using wiki framework, and (4) share/sync edited contents with other DL2Go users and the server using web services and RSS framework.
