Directory Service Provided by DSCloud Platform Lican Huang Hangzhou Domain Zones Technology Co., Ltd Hangzhou, China Huang_lican@yahoo.co.uk , Licanhuang@zstu.edu.cn Abstract—When there are huge volumes of information dispersing in the various machines, global directory services are required for the users. DSCloud Platform provides the global directory service , in which the directories are created and maintained by the users themselves. In this paper, we describe the DSCloud Platform directory service’s functions, authorization, mounting users’ local file systems , and usage scenery for education. Keywords—directory service; DSCloud Platform; Hierarchical domains; File systems I. INTRODUCTION There are huge amount information in Internet, some in Web Servers, cloud platforms, others in users’ personal computers or mobiles. There are also many resources in Internet of Things. The information may be many types, including text, files, or even real-time sensing data. On the other side, social activities of users also are classified into specific groups, such as Facebook , Linkedin, Weichat, etc. Therefore, a directory service is beneficial for the users today. A directory service provides access to information in a directory. Unlike file systems in operating systems, global directory service for all users provides convenient access for global distributed information. Yahoo[1] and Amazon[2] provide directory service on the Internet. However, these directory services are made by small number of specialists. It is impossible to provide the satisfactory directory services for all the users. DSCloud platform[3] is a software whose final goal is to provide various services for global users based on semantic P2P networks[4,5,6,7,8,9,10], in which all information is classified into hierarchical domains. It consists of website and sP2P Server. The client user usually uses browser and sP2P Client to finish his tasks. For DSCloud platform, that all global users share a global common directory is very important. Therefore, we implemented DSCloud platform to provides a global directory service by which the directories are created and maintained by the users themselves. DSCloud platform organizes all directories using hierarchical tree from root directory. This paper presents a global directory service provided by DSCloud Platform, the authorization of the directory service , the functions for mounting users’ local systems, and usage scenery for education. II. GLOBAL DIRECTORY SERVICE PROVIDED BY DSCLOUD PLATFORM DSCloud Platform organizes all categories into hierarchical directory (domain) tree starting from root “ALL” as Fig. 1 shows. In the paper, the directory and domain all most mean the same thing. To create new directory, the first step is to locate the parent directory in which we create the new one. There are three ways to locate the parent directory. Fig.1. hierarchical directory (domain）tree DomainTool (Domain class ) At every page of the platform , there is main menu containing “RootDomainTool menu”. RootDomainTool menu goes to DomainTool for root directory. Every directory can go to its own DomainTool. DomainTool has lots of functions including maintaining directory, managing user groups, authorization of the directory and other applications such as social communications and online education, and so on . DomainTool shows current directory (current domain) and sub directories ( sub domains) as the figure 2 shown. We can step by step locate the desired directory by DomainTool from root via sub domain . Fig.2. DomainTool Directory Navigator Bar (Domain Navigator Bar) Directory Navigator Bar is a directory bar , in which we can go to DomainTool and article list for any parent directory(as Fig. 3 shown). Fig.3. Directory Navigator Bar By click the directory name (domain name) in Directory Navigator Bar, we can go to current DomainTool, by click the icon aside the directory name (domain name) in Directory Navigator Bar, we can go to the article list of the current domain. As the above figure, when click the blue words ，it goes into the related domain tool . For example, when we click “Operating System” , it will go to DomainTool for operating System directory. Search Box In main page of the platform, there is Search Box, by which we can quickly locate the desired directory( see Fig.4). Fig.4. Search Box The input of Search Box contains search words and option selection. if search words contains “ and “ (“and” left side and right side have one space each) , the target contents must satisfy these split words at the same time. For example , if using ” protocol and course” to search directory, the target directory navigator bar must contains “protocol” and “course” at the same time. If select option is “DIR” , search the related directory, and display the contents as directory navigator bar, and help you quickly find the desired directory. If select option is “KEY” , search the related words in article title and abstract
