\begin{document}
A \emph{digital object} in a digital library is the textual or multimedia data and the metadata.

Formally, a digital object $DO$ is a quadruple $(h, SM, ST, SS)$ where
\begin{enumerate}
\item $h\in H$, where $H$ is a set of universally unique handles (labels);
\item $SM = \lbrace sm_1, sm_2, . . . , sm_n\rbrace$ is a set of streams;
\item $ST = \lbrace st_1, st_2, . . . , st_m\rbrace$ is a set of structural metadata specifications; and
\item $SS = \lbrace stsm_1, stsm_2, . . . , stsm_p\rbrace$ is a set of Structured Streams functions defined from the streams in $SM$ and from the structures in $ST$.
\end{enumerate}
