In-Depth Information
Here is how messaging services support different stages of the process:
1. Submission - One member is registered for the one-stop portal ( Portal )and
one for the front-oce application providing services through it ( FO ). The
portal creates a channel ( c1 ) to communicate with FO ,and FO subscribes to
it. Given this structure, each service request submitted through the portal
is sent through the channel to the front-oce application. The following
horizontal extensions can be provided for the messages exchanged through
c1 : Logging to assess the number of applications submitted, Validation to
assure that the front-oce receives valid data, and Encryption/Decryption
to protect the data transmitted through the net.
2. Completeness Assessment - The only communication required is notifica-
tion to applicants in the case of incomplete documentation. Once complete,
the application is forwarded to the back-oce application. The FO member
creates the channel c2 for this purpose, and the back-oce application regis-
ters a member BO who subscribes to this channel. In addition, the Auditing
service can be provided for c2 to keep track of the applications sent.
3. Evaluation - At this phase, collaborations from other agencies are required.
Each agency registers a member - PW , LE , CA , FB and HD ,and LG representing
the licensing agency. BO creates the channels: c4 to communicate with PW ; c5
to ask opinions from LE , CA , FB and HD ; c6 to communicate with LG ;and c7
to notify FB and HD about the inspection dates confirmed by the applicant
and to receive the inspection results. PW subscribes to c4 ; LE , CA , FB and
HD subscribe to c5 ; LG to c6 ;and FB and HD to c7 . In addition, BO creates
the channel c3 to communicate the status of the process to Portal ,who
subscribes to it. The Authentication extension is enabled for c3 to assure
that the messages are sent by the BO application. The information sent by
this channel is used when applicants track their applications.
4. Decision-making - No messaging service is required at this stage.
5. Fol low-up - Notifications to applicants are the only communications taking
place. They are provided by the infrastructure.
In order to support the correct execution of the process, the following ver-
tical extensions are provided: Process-Enforcement to assure the sequence of
messages exchanged through channels c4 to c7 conforms to the business process;
Tracking , over the same channels, to enable BO to track the process execution; and
Channel-Composition to link c6 and c7 . By enabling Process-Enforcement ,a
new member process is registered who creates the channel p-4567 . All channel
owners subscribe to p-4567 to forward the messages received through their chan-
nels to process .Thus, process can control if the messages are sent in the correct
sequence. By enabling Tracking ,anewmember track is registered who creates the
channel t-4567 . This member is subscribed to all tracked channels c4 through c7 to
receive a copy of all messages exchanged through them, and therefore enable track-
ing. The extension is configured by specifying for each message exchanged what
is the corresponding business step. By enabling Channel-Composition ,member
compose is registered and subscribed to c6 and c7 , responsible for forwarding all
messages from c6 to c7 .
