Directory Facilitator GUI
The GUI of the Directory Facilitator shows a tabbed pane
with three different views of the functions provided by a DF.
The three views are:
- Registration with this DF shows a table with all
the agents registered with the DF.
- Search Result shows a table with the list of agent
descriptions that were returned as a result of the last
search operation on a specified df.
- DF Federation shows the DF federation. The Parents
table shows the list of DF's with which this DF is
federated, while the Children table shows the list of
DF's that are registered with this DF.
According to the tab selected, the actions allowed have
a proper meaning:
Registration with the df
- View the description of the selected agent from
the table.
- Modify the description of the selected agent.
- Register an agent with the DF. The user is then
requested to fill in an agent description, notice that
some values are mandatory for registration.
- Deregister an agent selected in the table.
- Search for agent descriptions with this DF. First
of all the user must insert the constraints of the
search.Two kinds of constraints are permitted: the depth
of propagation of the search operation to the federate
DF's and the maximum number of returned agent
descriptions.If no values are inserted the default
constraints will be used (local search on this DF and all
agent matching returned). Then the user must insert an
agent description. If no value is inserted in the agent
description, the search action returns all the active
agents currently registered with this DF.
- Federate allow to federate this DF with another
DF. The user must provide the AID of the DF with which to
federate and then the description of this DF to use to
register itself with the specified DF .
Search Result
- View the description of a selected agent on the
table of the results.
- Modify the agent description of the
selected agent with the DF indicated on the tab.
- Register a new agent with the DF
indicated on the tab (the Df on which the search was
made).
- Deregister the selected agent from the
DF indicated on the tab.
- Search for agent descriptions with this DF.
DF Federation
- View the description of an agent selected in one
of the two tables. If the agent selected is a parent,
then the description used by this DF to federate with the
parent is shown. Otherwise if the selected agent is a
child, then the description of this child DF is shown.
- Deregister If the selected agent is a parent then
this DF is deregistered from the selected one, otherwise,
if the agent selected is a child, this child is
deregistered from this DF.
- Search permits to make a search with the DF
selected in one of the tables.
- Federate allows to federate this DF with the one
whose AID will be indicated.
