8 Semantic Web Architecture

9 P-Commerce (Multimeetmobile Concept) We based into assumption that the future growth of m-commerce information services (more specifically - in location-based information content sailing) nowadays not as much depends on huge content providers but more depends on public business activity. An ordinary mobile user is transforming now from a consumer of commercial services to also a supplier of them.

10 P-Commerce (Multimeetmobile Concept) Every person in the society in some way more or less participates in public business process, which we name as public commerce (p-commerce). We are buying something from another persons watching newspapers with public offerings or we are selling something unnecessary making announcements in numerous places by numerous ways. Some of us even sometimes make small business by finding in news offerings and requests that fit each other.

11 P-Commerce Service P-Commerce service should be able to integrate different types of information with geographical data and manage different type of profiles related to preferences, security, privacy, transaction management, etc. It should be able to find the best match between any public offering and any public request and support all necessary negotiation, contracting and billing activities

12 P-Commerce (other concepts) 4 postal commerce 4 postal commerce [history] - this is where you get a catalog in the mail, or read an insert in the local papers, call a toll- free number and order an item 4 position-commerce 4 position-commerce [ATX Technologies] - wireless access to infotainment and commercial services that are based on a subscriber's location and personal preferences 4 people commerce 4 people commerce [Elgin Scott] - bridge between IT firms on the one side, and candidates, job agencies and other elements of the recruitment process on the other 4 pocket commerce 4 pocket commerce [BarPoint] - a user can simply swipe products as if checking out items in a grocery story and then let BarPoint deliver an in-depth profile for each one

13 P-Commerce (other concepts) 4 personalized commerce 4 personalized commerce [METAFrame Tech. GmbH] - is to collect personal profiles, to deliver more targeted content and advertising 4 pervasive commerce 4 pervasive commerce [iConverse Wireless Application Platform] - trend, which means a transition from focusing on HTML browsers to focusing on multi-model interfaces and delivery involving a wide array of devices and interfaces

14 P-Commerce (Multimeetmobile Concept) 4 public commerce 4 public commerce [Terziyan, 2001] - is an integration of best features of previous p-commerce concepts. This is an attempt to integrate modern mobile location based services with public business activities. 4 Multilevel profiling framework 4 Multilevel profiling framework [Terziyan, 2001] is proposed as the way to simplify for every ordinary person the way to e-commerce market.

15 Public Commerce (inheritance of previous concepts) 4 Public commerce 4 Public commerce should provide possibilities for public to advertise, sell and buy goods (from postal commerce to pocket commerce), and even manage human resources (people commerce). 4 Public commerce 4 Public commerce provides commercial services that are based on a subscriber's location (position commerce). 4 Public commerce 4 Public commerce service should be adaptive to subscriber preferences (personalized commerce)... 4 … and to abilities of certain mobile device (pervasive commerce).

16 General Architecture for a Mobile P-Commerce Service

17 Multilevel Profiles in P-Commerce Multilevel profiles assist to reach consensus between a buyer and a seller about general and specific features of their relationships: 4 International and local laws, standards (transaction management, payment, security, privacy, and so on) ; 4 Metaprofiles (Meta DTDs - Meta Document Type Definitions, Ontology Vocabularies) ; 4 Profiles (for security, for privacy, for preferences, for transaction management, for negotiations, for orders and invoices, for shipping schedules, for contracting and billing, and so on) - DTDs (Document Type Definitions), Common Business Library patterns, RDF schema; 4 Interpreted profiles (concrete XML documents, which described different features of reached consensus).
