==============
GNOWSYS Studio
==============
A collaborative workspace (studio) for constructing and publishing semantic
knowledge networks and ontologies.
Features
========
The application is devided into two sub-apps. Gstudio and
Objectapp. The former includes classes for organizing the network or
constructing an ontology. The latter includes classes for holding the
instances of object-types, process-types and system-types.
Gstudio Components
------------------
* Metatypes
To hold Classes which have other classes as its members. e.g. "abstract noun", "adjective", "phylem", "class", "genus", "species" etc.
* Object types
To hold Classes: e.g. "thing", "being", "living being", "animals", "cat", "place", "person" etc.
* Relation types
To define binary relations (object properties) between classes and objects. e.g., "part of", "friend of", "composed of", "located in" etc.
* Attribute types
To define datatype properties for classes and objects. e.g., "population", "size", "length", "height", "first name", "phone number" etc.
* System types
To bring together some of the classes into a system or
an ontology, a collection of the types defined above for
convenience. You can bring together the required classes, relations
and attributes into
* Process types
To define a process as prior and post states of classes or objects.
* Attributes
To store attributes
* Relations
To store binary relations
* Node Specification
A node specified (described) by its relations or attributes or both.
* Relation Specification
To create an expression using a relation with a subject, e.g.,
"friend of Tom", "components of a cell" etc.
* Attribute Specification
To specify an attribute by a subject to say for example: population
of India, color of a flower etc. These do not yeild a proposition
but an expression, which can be used as a subject in another
sentence.
* Expression
Expression is more like a relation between two terms, but it does not yeild a proposition, e.g.,
"Researchers in India", "students residing in India" etc. It is modelled more like relation
class, except that the result is not a proposition/triple.
* Union
To define a class by a union relation between two or more classes.
* Complement
To define a class as a compleemnt of two or more classes.
* Intersection
To define a class as an intersection between two or more classes.
Objectapp Components
------------------
* Objects
To hold the instances of Object types: "Mumbai", "Tom" etc.
* Systems
To hold the instances of System types.
* Processes
To hold the instances of processes.
Online Collaborative Platform
=============================
The application is built as a collaborative on line platform with the following features.
Version Control
---------------
All the changes by the users will be recorded. This feature is implemented using using django-reversion.
User Registration
-----------------
Basic registration, authentication mechanism.
Network Navigation using SVG graphs
==================================
* neighbourhood graphs and concept graphs
Other Semantic Web features
===========================
* data in RDF format
* rdf feed to a triple store
* sparql endpoint
Features to be implemented
==========================
* export and import of standard knowledge representation languages: CL, OWL, XTM etc.
Features adopted from Django-Blog-Zinnia
========================================
The following features are adopted from django-blog-zinnia code base
with a lot of gratitude. Thanks to an excellent codebase of
django-blog-zinnia, which taught us best software development
practices as well! After reviewing each feature for the purpose of
semantic blogging, we will retain or extend the following features.
* Comments
* Sitemaps
* Archives views
* Related entries
* Private entries
* RSS or Atom Feeds
* Tags
* Advanced search engine
* Prepublication and expiration
* Edition in MarkDown, Textile or reStructuredText
* Widgets (Popular entries, Similar entries, ...)
* Spam protection with Akismet or TypePad
* Admin dashboard
* MetaWeblog API, xmlrpc
* Ping Directories
* Ping External links
* Bit.ly support
* Twitter support
* Gravatar support
* Django-CMS plugins
* Collaborative work
* Tags autocompletion
* Entry model extendable
* Pingback/Trackback support
* Blogger conversion utility
* WordPress conversion utility
* WYMeditor, TinyMCE and MarkItUp support
* Ready to use and extendables templates
* Windows Live Writer compatibility
