The network construction uses the following principles:

1. Everything is a node. The memory in GNOWSYS is a set of nodes with all nodes with a unique NID (Node ID). The NID with the address locator gives rise to a unique URI in the cyberspace.
2. A node links with the neighborhood nodes through relations, and some predefined name and value pairs called attributes.
3. Every node is described/interpreted by neighborhood, which is nothing but the set of relations and attributes a node possesses. This can be rendered as a context graph.
4. A network can be obtained by merging the neighborhood of all the nodes as a graph.
5. The set of all attributes and relations is the full set of knowledge represented in the network in the form of propositions.
6. Each attribute or relation constitutes one RDF triple expressing one proposition.
7. The representation of network memory can be completely encoded in any of the RDF notations.

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

Based on the type of attributes and relations, we can distinguish some widely repeated kind of patterns as node types for convenience. These node types can be used for managing the data of computing applications. New nodetypes can be defined as and when required, though minimalism is encouraged for ensuring generality of processing engines and maintaining parsimony. Currently GNOWSYS has the following node types:

1. Type Nodes:
   • Metatype
   • System Type
   • Attribute Type
   • Relation Type
   • Process Type
2. Token Nodes:
   • Systems
   • Processes
3. Triples:
   • Relations
   • Attributes
4. Special Derivative Nodes (to be implemented):
   • Union
   • Complement
   • Intersection
5. Complex Expressions:
   • Node Specification
   • Relation Specification
   • Attribute Specification
   • Expression

GNOWSYS is an acronym for Gnowledge Networking and Organizing SYStem. The 'G' in GNOWSYS is pronounced hard just as the 'G' in GNU.

• A distributed knowledge network.
• Metadata can also be added to relations and attributes.
• All changes to the data as well as to the metadata of knowledge is tracked.
• Methods are accessible to clients and other servers as web services and through XML-RPC or jsonrpc, as well as restful protocol.
• Define arbitrary relations and attributes. subtyping, and class membership are inbuilt. All the datatypes provided by mongodb are supported.
• Metatype (type of types) and relations among them can also be expressed. Useful for knowledge representation using upper ontology elements.

Consider using GNOWSYS if you want a distributed database, your data model is evolving (not yet frozen), you are a semantic web engineer and wants to develop an ontology, or publish several ontologies in one networked memory, you want a distributed triple store with frame and graph based views, if you are doing structured content management application, etc.

You may use GNOWSYS:

• As a web based hybrid database (as a file system, RDBMS, OODBMS, distributed DBMS) with querying and remote management. This ability will make it highly suitable for agent oriented computing solutions across the Internet.
• For building structured knowledge bases with a higher degree of expressiveness. This will help build AI based applications using GNOWSYS as a database. (GNOWSYS has no inbuilt inference engine (Ongoing work). However it is possible through the SPARQL endpoint provided by 4store.
• For semantic web. All data stored can be exported as RDF (N3 notation completed), and can be imported from RDF (Ongoing work).
• Since GNOWSYS database is available as a web-server, dynamic web sites and web services can be made. Web sites built with GNOWSYS are "semantic web ready", for the structure of the data can be queried by software agents. Normal dynamic web sites conceal the database structure, while GNOWSYS sites do not.
• Any web framework can make use of the data stored in the GNOWSYS knowledge base though XML-RPC/jsonrpc.
• As a digital encyclopedia, thesaurus, dictionary or glossaries can be made very easily.
• For building elearning applications. Lessons and concepts (learning resources) can be organized according to the standard metadata suggested by LOM/SCORM models. Learning paths, evaluation tracks, usage history etc. can be persistantly stored and accessed by establishing networking relations and conditions among them. SELF Platform is implemented using GNOWSYS.
• For building community portals, egovernment solutions, or any such applications that require the special features outlined above.

The current implementation uses Django-framework to expose the construction and publishing methods of knowledge networks.

If you think you have found a bug in GNOWSYS, then you should send as complete a report as possible to the developer's team in the mailing list.

GNOWSYS is conceived and authored by Nagarjuna G. Most of the code to GNOWSYS was a contribution by several staff members and students who worked under his guidance at Homi Bhabha Centre for Science Education, TIFR, Mumbai. Shashank Ashtikar and Harshad Bahere were the initial contributors to the code and later on by Prasanta Baruah, Debarshi Ray and Rakesh Pandit. Bipin Apandkar, Rajiv Nair, Alpesh Gajbe, Dinesh Joshi, Vihan Pandey, Saurabh Shelar, Krishnakant Mane, Shaswat Chakravorty, Divya, Jay Mehta, Kabir, Johnson, Anuja, Supriya, and Ganesh Gajre.

The current active contributors include Anuja, Supriya, Dhiru, Krishna, Avadoot, Johnson, Arun, Kedar, Sunny, Kabir and some student interns of the gnowledge lab.

If you would like any new feature to be included in future versions of GNOWSYS, please talk to developers' team in the mailing list.

GNOWSYS development is currently supported by Homi Bhabha Centre for Science Education (HBCSE), TIFR, and is mostly executed by undergraduate students as a part of their projects. Please remember that GNOWSYS is a GNU project and is dedicated to the free software community. If you like to be a volunteer, you can also contribute to its development. This project is managed from savannah site. You can place a request to be a developer from there. For information about contributing to other GNU Projects, please read How to help GNU.

Presently no translation exists. If any of you wish to volunteer to translate this page to your language, please contact the maintainer, <nagarjun AT gnowledge DOT org>.
