ATerm (short for Annotated Term) is an abstract data type designed for the
exchange of tree-like data structures between distributed applications.
The ATerm library forms a comprehensive procedural interface which enables
creation and manipulation of ATerms in C and Java. The ATerm implementation is
based on maximal subterm sharing and automatic garbage collection.
A binary exchange format for the concise representation of ATerms (sharing
preserved) allows the fast exchange of ATerms between applications. In a typical
application---parse trees which contain considerable redundant
information---less than 2 bytes are needed to represent a node in memory, and
less than 2 bits are needed to represent it in binary format. The implementation
of ATerms scales up to the manipulation of ATerms in the giga-byte range.
