Title

File-Management for MultimETH


Introduction

MultimETH is a distributed (Multi-media) conferencing system, which allows 
members of a conference to share files and edit them simultaneously. Each 
conference-member has it's own private workspace PWS and access to the shared 
workspace SWS, residing at the location of the conference server.


Tasks, Goals

An application has to be created which is part of MultimETH and allows the
members to browse above mentioned workspaces. In these two filesystems several
operations have to be created, allowing Copy,Move,Delete,Attribute-Change,
Start of an Editor,Transfer SWS<->PWS of documents. Fileaccess-Control mechanisms
have to be created. The integration of an existing editor into the MultimETH-
System is also part of this work.


Results

An Andrew-based user interface and the full functionality of the browser have
been realized. Files that are currently edited in SWS are shown as locked,
unchangeable files in the user interface. Remote Operations in MultimETH have
been extended to realize the browsing functions, and the transfer of documents
between SWS and PWS. Integration of the editor has taken place, insofar as
the editor can now check access-permission on files, and editor-server and
-client are automatically started and terminated by MultimETH-server -client
and -browser.


Future work

The user interface may be extended to allow the change of more file-attributes
than now. The document-history could be presented and updated by operations on
the file. The fileaccess-system could be extended to allow the setting of 
MultimETH-permissions for whole directories. Remote operations could be provided,
that allow the copying of whole directories from SWS<->PWS.
