What is Sametime
Sametime is a client/server real-time collaboration product
Sametime is NOT just an “instant messaging” product, but rather
it offers a large set of capabilities like:
People Awareness
Instant Messaging
Place-Based Awareness
Collaboration Meetings
• Chat
• Screen Sharing
• Whiteboard
• Audio and Video
And more…
4
Sametime out of the box
On the server side
Community Server
Meeting Server
On the client side
Sametime Connect for Browsers (a.k.a. Java Connect)
Sametime Connect for Desktop (a.k.a. C++ Connect)
MRC (Meeting Room Client)
….
5
What are the Sametime Client Toolkits
The Sametime Client Toolkits provide the ability to
Sametime-enable client side software applications in
Java, Windows and Web environments
The Sametime Client Toolkits come in 4 flavors

Note: Community Services refers to the
group of services available from the
Community Server. The Community
service is simply one of the Community
Services.

Login as anonymous (limited access, permissions controlled by
administrator)

DND (Do not disturb)
Change your privacy settings (who can see me)
13
Awareness Service
Watch users
User status
• Online (Active, Away, DND)
• Offline
User attributes
• Microphone
• Speakers
• Video Camera
• Etc.
Watch server side groups (a.k.a. public groups)

Watch server attributes
14
Audio
Video
Directory Browsing
Etc.
Places Service
The Sametime places architecture provides a flexible and
robust model that supports place-based awareness and
collaboration.
A Sametime virtual place is an abstraction of a meeting
place in which users collaborate in various activities
Examples of a place:
a web page (URL)
a document
a discussion forum
a website
15
Places Service (cont.)
A virtual place is defined by its name so anything that can
be represented as a string can be a place.
Sections - In the Sametime places model, a virtual place
is made out of sections.
Activities – These are server-side applications that share
the place with the users, and define ways in which they
can collaborate.
Place members – Users, Sections, Activities are all place
members.
Attributes – All place members have a list of properties
describing them, and can also have a list of attributes
(key/value).

What you can do in a place
Entering and moving
By default all users can enter the place and move freely to other
sections
The exception to the above can be restricted by an
AllowedUsersList
Communication in a place
Direct text/data messages
Using member’s attribute
18
Lookup Service
Most Sametime operations that deal with users or groups
require STUser or STGroup objects as parameters.
The resolve operation matches a name to provide either
an STUser or an STGroup object.

19
Resolve user names
Resolve server-side group names
Handle resolve failed and resolve conflict situations
Query the content of server-side groups
IM service (Instant Messaging)
Allows you to send/receive text and/or binary messages
between clients
It is used for standard IM, but it can also be used for
passing any other messages, such as game moves and
translated messages.
The service uses an IM type parameter to classify
message sessions of different type
Types 0 – 10000 reserved for Lotus internal usage
Third party IM types should be registered with Lotus
Example: Start/Stop responding in Sametime Connect
20
Token service
Provides the ability to generate a token that can be used
by a logged-in user to log in to the Sametime server, from
a different application, for example, without being
challenged to authenticate again.
See Community service loginByPassword() vs.
loginByToken().
21
Storage Service
Stores user related information (user preferences for
example) as attributes on the Sametime server.
Allows you to access these attributes from whenever you
login to your Sametime server
When you are logged-in from two or more clients
simultaneously, modifications in your storage attributes
posted from one client may be received by the other
clients.
Note: Do not confuse the attributes used in this service with
the online attributes of the Awareness or Places service.
22
BuddyList service
Provides the ability to get a user’s contact list from the
user storage (attribute #0), on the Sametime Server, or
store it there.
Provides conversion methods between String and BL
objects. This is used for example to store/retrieve a
contact list to/from the local file system.
Provides methods to construct BL objects (contact list).
In fact this service is a convenience service, that extends
the Storage service. It hides from the developer the low
level protocols defined by the Storage service, and
provides construct and parse methods for the user’s
contact list.
23
Names service
To customize the display name of your users inside an
application.
Examples
To make the display name shorter by having the name cut at some
predefined delimiter, like “Joe Smith/Organization” will be shown as
“Joe Smith” (delimiter=“/”).
Just replace the display name by a “nickname” like “Joe”
Note: This service is a local service and has no equivalent
server-side component (in the C++ Toolkit this service is
part of the Community service).
24
Directory service
Enables to browse the Sametime community directories,
provided that the directory configuration allows this.
Provides a list of all available directories and allows to
query for chunks of entries in each directory.
Note: If your Sametime server is configured to use an
LDAP directory, directory browsing is not enabled.
25
Post service
Allows the sending of messages to many users at once,
and allows the user to respond to the message they
received.
Example – A company secretary sending a meeting
reminder to all the meeting participants
26
Announcement Service
An announcement is a message that can be sent to one
or more people. You can send an announcement to a list
of STUser and/or STGroup instances.
Optionally sender may allow recipients to respond.
Very much similar in functionality to the Post service, but
different in the following aspects:
Better performance than the Post service
Recipient list can include server-side groups
Note: In the C++ Toolkit this service is part of the
Community service.
27
FileTransfer service
Provides the ability to send and receive files between
Sametime users.
The initiator creates a FileTransfer object and starts the
transfer.
The other side can accept or decline the transfer.
After the file transfer starts, both sides receive progress
notifications and can stop the transfer before it completes
successfully.
28
Meeting services
Allow clients to create and join multi-participant meetings.
The services include
Application Sharing
Whiteboard
Streamed Media (Audio/Video)
Development over the Meeting Services are available only
in the Java Toolkit, but still it is possible for a C++
application to launch the Java Meeting Room Client
(MRC).

What is the Sametime Server Toolkit?
The server toolkit provides the ability to:
Enhance and extend Sametime server side services
Create your own Sametime server side service
Support new clients
The server toolkit is Java-based
The server toolkit is an extension to (a superset of) the Java
Client Toolkit
Examples
Sametime Bot – an application that can be added to the buddy list just like
another user, providing answers to queries submitted by the user
Activity providers (for activities in a place)
