Addresses for GNUstep
=====================

(c) 2003 by Björn Giesler <bjoern@giesler.de>
---------------------------------------------


This package constitutes a personal address manager for the GNUstep
software system. It allows archiving complete personal contact
information, organizing contacts in groups, integration with other
software such as mail clients and sharing address information with
other users over the network.

TECHNICAL INFORMATION
=====================

Addresses is organized in components. There is

    o a database API backend framework called Addresses.framework.
      This backend provides complete access to address information for
      applications. It is source-code compatible with Apple
      Corporation's AddressBook.framework.

    o a display/edit framework called AddressView.framework.
      This library provides specialized view classes to applications
      which want to display addresses to the user in a graphical
      form. There are two main classes:

        o ADPersonView, to display and edit complete information about
          a person in a visually appealing style. This view is
          intended for specialized Address Manager applications.

        o ADSinglePropertyView, to display person names together with
          values for a single other property (such as email
          address). This view is intended for applications such as
          Email clients, in which the user should select one or more
          contacts to perform some operation on them.

    o a dedicated Address Manager application, which uses both of
      these frameworks and acts as an easy-to-use and visually
      appealing database frontend.

    o a number of command-line helper tools, such as converters
      from/to specific address formats, an address book network
      server, etc.
      
NOTE ON INCOMPLETENESS
======================

This software package is still in the early stages of
development. Expect changes in database format, functionality, and
just about anything else. There is no warranty, express or implied,
that this package is good for any particular purpose, or if it is,
will remain so in the future. Expect breakage.

That said, if you find anything buggy or not to your liking, please
send me mail at bjoern@giesler.de.

Another thing, not to be taken personally: This software is clearly
inspired by the Apple Address Book. If it's not NeXTish enough for
you, please feel free to submit changes in the form of .gorm files or
whatever. I am quite happy with the UI as it is, and quite unwilling
to listen to any more complaints about what should be a panel and what
shouldn't and what has to be grouped in a window and what
shouldn't. None of us works for NeXT anymore, so none of us knows what
THEY would have done. As I said, if you submit patches that make the
look configurable, I'll be happy to integrate them.


EXTENDING VIA PLUGINS
=====================

To keep the library and application as open as possible, it is extensible via
plugins. These are loaded from the usual places: 

	 $(GNUSTEP_SYSTEM_LIBRARY)/Addresses
	 $(GNUSTEP_NETWORK_LIBRARY)/Addresses  
	 $(GNUSTEP_LOCAL_LIBRARY)/Addresses
	 $(GNUSTEP_USER_LIBRARY)/Addresses 

There are currently two kinds of plugins, and they usually appear in pairs of
two: plugins that provide new address book classes, and plugins that contain
GUIs to configure them.

One reason to write such plugins is that you might have a corporation-wide
address book that you want to browse or synchronize with. 

Please look into Frameworks/Addresses/ADPlugin.h and AddressManager/Plugin.h,
as well as the goodies/LDAPAddressBook directory, for documentation and
examples on how to write such plugins.


LICENSE
=======

This software package is distributed under the terms of the GNU Lesser
General Public License (LGPL); please see the file COPYING.LIB for
details.

There is one important license issue to note: In the case of the work
at hand, a bundle containing class extensions to Addresses.framework
or AddressView.framework is to be considered a "work that uses the
library", not a "work based on the library" in terms of the LGPL. In
layman's terms: If you write a bundle containing a subclass of
ADAddressBook (eg a MS Exchange connector), this bundle does not have
to be released as source code.
