INNOV-06 RFID Enabling your OpenEdge
Application

• John Trigg
• Principal Product Manager

2
Session Goals

• Present an architecture for integrating RFID
  event capture into your OpenEdge applications
• Shipping receiving docks,
• Packing stations,
• Conveyor systems,
• Introduce the OpenEdge RFID Library and how it
  can help you meet your application RFID demands

3
RFID Events

• Signal the placement or removal of a tagged item
  in or from the detection field of an RFID reader
• Event attributes
• Time
• Tag ID (EPC)
• Reader ID
• Action (Add or Delete)
• May trigger a business event

4
RFID Business Events

• Events derived from low level RFID events and
  other inputs. Puts events into a business context
• Event attributes
• Business action (pack, ship, receive, )
• Location (DC 23, Dock 9, )
• Tag IDs (EPCs)
• Time
• Input to business apps

RFID Event Processing Goals

• Insulate applications from high volume, noisy
  RFID event streams
• Insulate applications from specifics of readers
  to allow reader replacement
• Process events on the edge to minimize load on
  back-end systems
• Automate generation of business events from low
  level events
• Store events to allow audit and analysis of
  performance of business processes

Architecture for RFID Event Capture
7
The Event Layer

• RFID middleware (ALE)
• Application Level Event
• First line of defense against RFID noise
• Aggregates and filters RFID events
• Common API, independent of reader type
• RFID repository (RFID-Accelerator)
• Event history for audit and analysis
• Event buffer for store/forward, offline,
• RFID readers and sensors
• Physical devices on docks, conveyors,

8
The Application Layer

• OpenEdge application
• Standalone,
• AppServer,
• OpenEdge RFID Library
• 4GL API for accessing ALE and RFID-A event data
• Hides details of ALE and RFID-A web service
  interfaces

ALE Middleware

• Aggregates and filters RFID events
• Abstraction layer above readers
• Web-service interface for querying RFID events
  (ECSpecs ECReports)
• Query/Reply model and subscriptions (HTTP post,
  JMS, )
• Answers question what is at reader X now

11
RFID Accelerator

• Collection and storage of RFID event streams
  (keep out of ERP/WMS DB)
• Edge data store, buffering, track/trace,
• Greater noise reduction above ALE
• Web-service interface for querying RFID event
  history (EHSpecs EHReports)
• Query/Reply model
• Answers questions such as
• What passed through dock 5 yesterday between
  900 and 1100 AM?

12
What are Specs Reports?

• Specs define queries
• ECSpec Event Cycle Spec for ALE
• EHSpec Event History Spec for RFID-A
• Reports are the results of queries
• ECReport Event Cycle Report from ALE
• EHReport Event History Report from RFID-A
• XML documents passed via web service interface

OpenEdge RFID Library Overview

• OpenEdge library for integrating the processing
  of RFID events into OpenEdge applications
• Supports retrieval of RFID events from any ALE
  middleware (either query/reply or subscriptions)
• Supports retrieval of RFID event history from
  RFID-A

16
OpenEdge RFID Library Features

• Easy to use API provides a procedural approach to
  creating and issuing queries
• No need to know details EC/EHSpecs
• Event data presented as ProDataSets and
  TempTables makes it easy to process data in 4GL
• No need to know details EC/EHReports
• No need to know details of web services or SOAP

17
Demonstration 1 Receiving Dock Monitor

• Receives asynchronous reports from ALE as pallets
  of goods move through the dock
• As each report is received OpenEdge RFID Library
  creates a temp-table of tags which moved through
  dock and calls user procedure to process them the
  tags
• Same concepts apply to other RFID situations
  shipping, packing, conveyor ...)

Demonstration 2 Receiving Dock Analysis

• Queries RFID-A to determine goods received at a
  dock door over some time period
• For each report OpenEdge RFID Library creates a
  temp-table of tags which moved through dock door
  in that time period and the temp table is then
  processed by the application
• Same concepts apply to other RFID situations
  track trace, auditing, performance analysis,

OpenEdge RFID LibraryAPIs for ALE RFID-A

• The ALE and RFID-A APIs in OpenEdge RFID Library
  are very similar. If you learn one you know the
  other.
• Primary difference is for RFID-A you specify a
  date/time range of events to be retrieved for
  ALE you specify event cycle boundaries.

31
OpenEdge RFID Library Prerequisites

• OpenEdge 10.0B02
• RFID-A 3.1
• RFID Middleware Compliant with EPCglobal ALE 1.0
  specification
• ConnecTerra RFTagAware
• Others to be announced

32
Whats Missing in OpenEdge RFID Library

• Tag writing
• Not necessary if using 3rd party
  writing/labeling software. Here OpenEdge is a
  simply source of tag data
• Tag killing
• Will provide API for tag writing/killing when
  added to ALE standard

33
Data Management Strategy

• Comprehensive Data Management Strategy
• What data is relevant?
• Where must the data be digested?
• How does a tag read relate to other reads?
• What context is required to provide
  understanding?
• What reporting/sharing is required by internal
  users? By each trading partner?

34
EPC-IS A Proposed Data Management Standard

• New architecture proposed by EPCglobal
• Standard definition occurring amongst its working
  groups
• Goal is standardize the functionality and roles
  of an EPC repository
• Capture of low level events
• Transformation
• Application of business context
• Data sharing with trading partners

35
RFID Event Management

• RFID events are being processed at the edge
• Where the events occur
• Frequently morphing into existing transaction
  formats
• Upstream relay of events into enterprise
• Must allow for reporting/monitoring
• Must enable higher level events to be triggered
  from multiple edge-based event streams

36

7 Principles of RFID Data Management

1. Digest Data Close to the Source
2. Turn Simple Events into Meaningful Events
3. Buffer Event Streams
4. Cache Context
5. Federate Data Distribution in Real Time
6. Age RFID Data Gracefully
7. Automate Exception Handling
