A collaborative blogspace for constructing and publishing semantic knowledge networks and ontologies
A collaborative workspace (studio) for constructing and publishing semantic knowledge networks and ontologies.
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.
To hold Classes which have other classes as its members. e.g. “abstract noun”, “adjective”, “phylem”, “class”, “genus”, “species” etc.
To hold Classes: e.g. “thing”, “being”, “living being”, “animals”, “cat”, “place”, “person” etc.
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.
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
To define a process as prior and post states of classes or objects.
To store attributes
To store binary relations
A node specified (described) by its relations or attributes or both.
To create an expression using a relation with a subject, e.g., “friend of Tom”, “components of a cell” etc.
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 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.
To define a class by a union relation between two or more classes.
To define a class as a compleemnt of two or more classes.
To define a class as an intersection between two or more classes.
Objectapp Components ——————
To hold the instances of Object types: “Mumbai”, “Tom” etc.
To hold the instances of System types.
To hold the instances of processes.
Online Collaborative Platform
The application is built as a collaborative on line platform with the following features.
All the changes by the users will be recorded. This feature is implemented using using django-reversion.
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.
The features listed here are not thourougly tested. There is a likelyhood of misbehavior.
