Tasor server has RDF store as its data storage, and it can contain any amount of data. Data are stored as resources in one big graph (this is Semantic Web representation of data). Beside connections between resources, each resource can have its binary representation of data, for storing multimedia documents (another distributed data storage is employed for this). For easy manipulation of this data similar concepts are grouped together in Datasets (collection of semantically similar resources). Users in Tasor create, edit and share this Datasets. Datasets from various users and data sources are grouped together in Domains, which represents knowledge about some real domain.

Users search, browse and edit Domains of their interest. They can do this by their own or by joining community of experts in some domain. Resources are searchable in personalized way, based on user preference, search history and various social activities. By joining a user groups users have ability to participate in discussions, forums, massaging board and other social activities that helps them to get involved in building a better understanding in their interests.

All data is presented to user with advanced Web applications technology. All applications are aware of data semantics. Content that user is viewing by one application is constrained by desired Domain, language, and other user preferences. Users can switch applications while viewing data, to gain more desirable experience in data browsing. If user is still not satisfied with results he can change any aspect of application, to create new applications based on existing, or even request/propose changes to community.
