HAM: a general-purpose hypertext abstract machine

ABSTRACT

The Hypertext Abstract Machine (HAM) is a general-purpose, transaction-based, server for a hypertext storage system. The server is designed to handle multiple users in a networked environment. The storage system consists of a collection of contexts, nodes, links, and attributes that make up a hypertext graph. This paper demonstrates the HAM's versatility by showing how Guide1 buttons. Intermedia webs, and NoteCards FileBoxes can be implemented using the HAM's storage model.
