============== 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 Examples ======== A sandbox site will give you a preview of the application.
