Remove some obsolete documentation.
These date back to Evolution 1.x era or perhaps earlier.

This means that - CORBA requests sent to Wombat do not return values - inmediately, but rather than for Wombat requests the user has - to provide a CORBA object that will be notified of what - happened. - - Yes, that sounds hairy. It is actually pretty simple. It - basically means that you submit requests to Wombat, and a - callback is invoked in your code when the request has been - carried away. - - This enables a Palm to sync to the repository without having - the GUI for Evolution running. It also means that volunteers - will be able to write text-based and web-based versions of - Evolution (not me though :-). - -* Evolution as a platform - - Evolution is more than a client for managing the above - information: Evolution is a platform for building groupware - applications that use the above components to get their work done. - - To achieve this Evolution is designed to be scriptable, and it - exports its internals through CORBA/Bonobo. It is implemented - as a collection of Bonobo containers and Bonobo components. - - There is a clean separation between the views (the user - interface) and the model (the view). The views that we are - writing are GNOME based, and they talk to the Wombat CORBA - server. - - Wombat takes care of notifications to the various clients for - the data. - -* The overall organization - - A bar similar to outlook provides shortcuts for accessing the - various resources managed by Evolution: mail folders, - contacts, tasks, journal entries, notes, messages and other - user-defined destinations. - -* User interface widgets - -** The ETable package - - This package provides a way of displaying and editing tables. - - Tables are displayed based on a TableColumn definition that - defines the layout used for the display. Table Columns can be - nested, and the package does grouping of information displayed - according to the criteria defined there. - - This is used in multiple places throughout evolution: it is - used for the Mail summary display, for the TODO display and - TODO new data entry and for the address book. - - Nesting in the address book can be performed on various - fields. For example, a first level of nesting could be - "Company" and a second level would be "Country" the result is - a 2-level tree that can be collapsed expanded and contains the - information sorted/grouped by those two criteria. - - The user interface for this will be copied from Outlook: the - possibility of adding and removing fields with drag and drop - as well as grouping using drag and drop. - -* The Mail system - -** The Mail sources - - The mail system will support 4 sources of mail: - - POP3 (transfer to a local file). - IMAP - Local mbox format in $MAIL. - Local mbox format that have other delivery points. - - On top of that, it will be possible to browse existing mbox - archives (and possibly other formats in the future, like - Mailbox and Maildir). - -** Storing the mail - - Mail that gets incorporated into the system is stored in mbox - format, and summary files are provided for quick access to the - files. No modifications to the file on disk is performed (I - am not quite sure about this, perhaps we want to add the - status flags and some method for adding metadata to the mail). - - Summary files are rebuilt on demand or rebuild if the mbox - file and the summary file have got out of sync. - - A Metadata system that will enable us to attach information to - a message will have to be designed and implemented (enabling - users to add annotations to mails, and special keywords and - flags in a per-message fashion). - -** Folders - - Michael Zucchi is working on a system that will let users - easily define rules for splitting their incoming mail into - physical folders. - - A further refinement to Folders are Virtual Folders. This - basically provides a powerful search and viewing facility for - mail. It works like this: when a mail is "incorporated" into - Evolution it is scanned and indexed. - - Then users can enter queries into Evolution that will search - the entire database of messages. - -** Virtual folders - - Virtual folders will enable users to read/browse their mail in - new ways: by specifying search criterias, these folders will - contain messages that match the criteria given. - - There is more information about this in the libcamel - directory. - - We will index all headers from a message, and possible the - contents of messages and keep those on a separate file, to - enable users to query their mail database. - -** Mail summary display - - The summary will be displayed using the ETable package, to - enable users to add a number of sorting criteria and various - display methods for the summary view. - - The Outlook methods for displaying will be present on the - system. - - Message threading will be supported in Evolution. - -** Message display engine - - We are going to be using a combination of - libcamel/limime/libjamie to parse messages and render them - into an HTML buffer. - -* The HTML engine - - The GtkHTML engine will be used to display messages, and will - be extended to support a number of features that we require: - internal handling of characters will be based on Unicode - -* The message composer - - Regular features found in composers will be added: connecting - the composer to the address book, support for drag and drop - for including attachments, editing the message, archiving - drafts and archiving messages sent. - - Ettore has been working on adding editing support to the - GtkHTML and he is working currently on a Bonobo component that - will provide a ready-to-use Bonobo control for embedding into - other applications. - |
