IBM WebSphere Premises Server 6.1 Feature Pack for Sensor Event Services
Reusable Component details
The topics in this section describe the Reusable Components
that are included in the WebSphere® Premises Server 6.1 Feature Pack for Sensor Event Services.
Aggregation
The Aggregation Reusable Component records aggregation
of tags to a parent in the back-end system.
Commissioning
The Commissioning Reusable Component records the commissioning
of tags, optionally to assets, in the back-end system.
Decommissioning
The Decommissioning Reusable Component records the tags
that will be destroyed or no longer used in the back-end system.
Disaggregation
The Disaggregation Reusable Component removes aggregation
of tags to a parent in the back-end system. This marks the records,
which have been created using the Aggregation Reusable Component,
as deleted.
EPC
The EPC Reusable Component provides methods for working
with EPC values, including generation of valid EPC values that can
be written to tags. It also supports a query to decode an EPC value
into its constituent fields.
Inference
The Inference Reusable Component infers the presence of
tags based on aggregations from the back-end system. It uses previously
recorded aggregations to infer parent, children, and sibling relationships.
Info
The Info Reusable Component queries the back-end system
for detailed master data information for tags. It can be considered
a more detailed version of the Locating Reusable Component because
it returns information from the master data repository in addition
to returning the most recently observed event.
Locating
The Locating Reusable Component queries the back-end system
for the most recent location where a tag has been observed.
Observation
The Observation Reusable Component records observed events
in the back-end system. This is the simplest recording of sensor events
to a back-end repository. After being observed, events can be queried
using the Locating or Reporting Reusable Components.
Printing
The Printing Reusable Component prints tags through the WebSphere Premises Server print
API.
Reporting
The Reporting Reusable Component queries the back-end system
for tag and location history based on previously observed events.
Validation
The Validation Reusable Component queries the back-end
system to validate whether or not the tags passed to the validate
method are currently commissioned. A list of tag EPCs are extracted
from the input event and validated against the commissioning history.
Non-commissioned tags mean that the tag has never been commissioned
or the tag has more recently been decommissioned.
WBE
The WBE Reusable Component allows WebSphere Premises Server application
developers to forward tag read events to WebSphere Business Events to be
processed by the rules engine. In WebSphere Business Events, Event
Flows and Interaction Sets define the rules that are processed when
the tag read enters WebSphere Business Events.
