Database Reference
In-Depth Information
authorization information from CAS. Authorization information includes user roles/
permissions. Permissions are textual values that de
ne actions or behaviors and are
de
ned per service. A wildcard permission format (Apache Shiro) is used. Permissions
can consist of multiple levels delimited by colons, and levels can be de
ned by each
application following a prede
ned pattern. For example, the permission string
admin:
“
delete_role:SERVICE_NAME
has three levels:
admin
means that the permission is
”
“
”
for administrative tasks,
delete_role
is the action, and
SERVICE_NAME
is the
“
”
“
”
name of the service for which the action is permitted.
3.3 Zero-Programming Application Development
OpenIoT provides an integrated environment (i.e. OpenIoT IDE (Integrated Devel-
opment Environment)) for building/deploying and managing IoT applications. Open-
IoT IDE comprises a range of visual tools (Fig.

) enabling: (a) Visual de
nition of IoT
services in a way that obviates the need to master the details of the SPARQL language;
(b) Visual discovery of sensors according to their location and type; (c) Con
guration
of sensor metadata as needed for their integration within the X-GSN middleware;
(d) Monitoring of the status of the various IoT services, including the volumes of data
that they produce and the status of the sensors that they comprise; (e) Visualization of
IoT services on the basis of Web2.0 mashups (i.e. maps, line/bar charts, dashboards and
more). These tools accelerate the process of developing IoT applications. In several
cases simple applications can be developed with virtually zero programming.
