....attitude towards anchoring, yet it is commonly implemented in many hypertext systems (for instance Microcosm [Dav92] and it is essential when dealing with free linking in read only data (es. CD ROM, cfr. Ore87] with open hypertext systems (cfr. Dav92] or widely distributed systems (cfr. [Mai93], Ore90] Our contribution to a complete definition of the anchoring mechanism has led to the introduction of new Z schemata and axiomatic definitions in the Dexter Model. Furthermore, several definitions have been revised through modifications regarding misconceptions and inadequacies found in ....

....an external repository so that creating a new anchor requires no modification to the data or the data container. Such systems require an explicit update mechanism for anchors since the data editor does not know of the anchor, which is useful in open hypertext systems [Dav92] distributed systems [Mai93] or when dealing with ROM and WORM devices [Ore87] and [Ore90] In Dexter terms, an external anchoring mechanism is one that allows Anchor Values to be stored externally to the Component they refer to. The Dexter Model clearly supports only internal anchors: specifiers store the Anchor ID, which ....
....own experience with checking the generality of the Dexter Reference Model. We used as an example the RHYTHM (Research on HYpertext THeory and Management) Hypertext System, which is being developed at the University of Bologna (for a complete description of RHYTHM, see [Lam92] Mai91] Mai92] and [Mai93]) In this section we emphasize the most prominent characteristics of RHYTHM, emphasizing where it mostly differs from those systems that inspired Dexter. In the next section, the main schemata of our model are presented. RHYTHM is a distributed hypertext system that, besides free linking ....
