Gnowledge lab team is happy to announce the release of GNOWSYS and
gnowsys-mode.

This is the first major release of GNOWSYS and gnowsys-mode (An Emacs
major mode as an UI for GNOWSYS) as a release candidate 1. If no more
bugs are reported/fixed in the coming two months, v 1.0 will be
released in May 2010.

The release can be downloaded from here:
http://mirror.lihnidos.org/GNU/savannah/gnowsys/gnowsysApp_rc1.tar.bz2
http://mirror.lihnidos.org/GNU/savannah/gnowsys/gnowsys-mode_rc1.tar.bz2

Release Notes:

This release is a major overhaul of the last stable release 0.62 (June
2006). After this GNOWSYS has been completely rewritten. =A0The major
changes are summarized below:

=A0+ The storage uses postgresql and not ZOPE object database (ZODB).

=A0+ Full version control of data and metadata is implemented making it
=A0 =A0a multiuser collaboration through the web, as well as through an
=A0 =A0Emacs client. (A major mode of GNU Emacs called =A0gnowsys-mode has
=A0 =A0been developed as a client to work collaboratively through
=A0 =A0Internet without using an Internet browser.)

=A0+ It is scalable and faster than all the earlier versions.

=A0+ It is standardized for use as a triple (RDF) store. (In the next
=A0 =A0release Ontologies can be published and managed collaboratively.)

=A0+ Graphs are drawn automatically for each node in SVG with
=A0 =A0hyperlinks.

=A0+ RDF export in N3 notation is implemented.

=A0+ Basic ontology editing is possible through the Emacs client:
=A0 =A0gnowsys-mode.


* A brief Introduction about GNOWSYS

=A0GNOWSYS (Gnowledge Networking and Organizing System) is a triple
=A0store (RDF) for representing knowledge networks and its dynamics.

** The Structure of the Network Memory

=A0 The network construction uses the following principles:

=A0 1. The memory in GNOWSYS is a set of nodes with all nodes with a
=A0 =A0 =A0unique NID (Node ID). The NID with the address locator gives
=A0 =A0 =A0rise to a unique URI in the cyberspace.
=A0 2. Every node links with the neighborhood nodes through two kinds
=A0 =A0 =A0of mediating nodes: attributes and relations. Thus every node
=A0 =A0 =A0can be represented as a frame.
=A0 3. Every node is described by neighborhood.
=A0 4. The network can be obtained as a graph by merging the
=A0 =A0 =A0neighborhood of all the nodes.
=A0 5. The set of all attributes and relations is the full set of
=A0 =A0 =A0knowledge represented in the network.
=A0 6. Each attribute or relation constitutes one RDF triple.
=A0 7. Search and query operations give the list of SSID (SnapShot ID)
=A0 =A0 =A0whose neighborhood contains the searched value.
=A0 8. The value space is linked to the nodes via named links making
=A0 =A0 =A0most results of queries meaningful.
=A0 9. The representation of network memory can be completely encoded
=A0 =A0 =A0in any of the RDF languages.

** The Dynamics (change management) of the Network Memory

=A0 1. Insertion of new nodes changes the neighborhood of the nodes
=A0 =A0 =A0concerned, and such changes can be tracked by holding the
=A0 =A0 =A0snapshots of the node's neighborhood at each instance of change.
=A0 2. Being a collaborative space, the system records who did what
=A0 =A0 =A0change and at what time.
=A0 3. Delinking is the preferred way of removing data elements from
=A0 =A0 =A0the network, and no node can be removed without prior removal of
=A0 =A0 =A0the links the node may have with others.
=A0 4. Each Node's neighborhood at a given time becomes the state space
=A0 =A0 =A0of the node.
=A0 5. Changing state of nodes can be recorded persistently as process
=A0 =A0 =A0nodes that record the prior-state and post-state of the nodes
=A0 =A0 =A0invovled.
