The work leading to the current Fenfire project (formerly known as GZigZag and
Gzz)
was started in 1999.
+Fenfire consists of three components:
-Our system uses xanalogical storage model [ted-xu-model]_ as a
-basis for hyperstructured media. Xanalogical storage keeps an index of
-transclusions: identical characters copied into different documents.
-Through this mechanism, the system can show to the user all documents
-that share text with the current document. In the xanalogical storage model,
-links are not between documents, but individual characters. For example, in
the
-World Wide Web links are between documents, while in the xanalogical storage
model
-links are between individual characters. Each character has a
-permanent, globally unique identifier. A xanalogical link is shown between
-any two documents containing the characters that the link connects.
Xanalogical links
-are external and bidirectional.
-
-The bidirectionally linked hyperstructural approach to information opens new
-possibilities to user interfaces.
-The user can connect any two items which
-will then be near each other in hyperspace, easily visible and
-accessible from one to the other.
-
-We study how location-independent identifiers can
-support *data mobility*. For instance, documents are often transferred quite
freely
-between computers: they are sent as e-mail attachments, carried around on
disks and
-published on the web. We use 'data mobility' as a collective
-term for the movement of documents between computers (or folders!),
-and movement of content between documents (through copy&paste).
-
-To support data mobility, we have developed a software library, named as Storm
-(STORage Module), for storing and retrieving data as immutable byte sequences,
which
-are identified by cryptographic content hashes. With Storm, we plan to use
globally
-unique, semantic-free references for locating data in Peer-to-Peer
environment.
-Location-independent identifiers allows a peer-to-peer lookup system find
documents
-wherever they are moved. We believe that the properties of Peer-to-Peer
technology,
-such as the ad hoc connectivity and the lack of central authority, are
prerequisites
-while mobilizing our system. Additionally, Storm allows us to study two
important
-issues *of data mobility*: dangling links and version management.

-In several hypertext systems today, following a link means a *disruptive*
change
-in the user's workflow, replacing the current context (e.g., a Web page) with
an
-entirely different one.
-This is partly caused by the dominant graphical user interface paradigm
-(developed in the 70s at Xerox PARC; see, e.g., [kay93smalltalk]_) in which
*pages*
-are shown in overlapping, rectangular, unconnected viewports (windows).
-In this paradigm, following a link can only create a new window
-or replace the contents of the current window.
-In our opinion, this is one of the root causes
-of hypertext disorientation

-Improving user orientation through user interface improvements has
-recently received much attention. There have been much work
-on providing more context of the link destination or making
-the transition less abrupt
[zellweger98fluid-andalso-fc-zooming-andalso-schilit98digital]_.
-However, the underlying one-directionally linked hyperstructure of
-the Web and many other hypermedia systems can also cause disorientation.
