allows the reader to pre-sort EPC’s at item, case and pallet level(Retail Consumer Trade Item, Logistical / Shipping Unit, etc.)

indicates length of GS1 Company Prefix(GCP ist 6, 7, 8, 9, 10, 11 or 12 Ziffern lang)

identifies issuing entity for subsequent parts of the EPC(eg., Sprockets AG, Friedrichshafener Str. 4711, 50823 Köln)

identifies specific type of item, location, asset or document(Item Reference / Location Reference / Asset Type / Document Type)

URI Forms for Pure Identities

URI forms for pure identities contain only the EPC fields that distinguish one object from another a different URN namespace is allocated for each pure identity type

Four Core EPCIS Event Types

Object Events• Observation of EPCs

SGTINs are moved into storage

Aggregation Events• Physical association of EPCs with parent EPC

SGTINs are picked and assigned to an SSCC

Quantity Events• Inventory of an object class (item reference)

a total of ___ of GTIN 56789 are currently in storage

Transaction Events• Link one or more EPCs to a business transaction

SGTINs corresponding to DESADV 4711 are shipped

EPCIS Read Point and Business Location

• Read Points are often doorways;Business Locations are often rooms:

Business Location: Store #23

Business Loc: Store #23 Back Room Business Loc: Store #23 Front RoomRead Point: Store #23 Dock #1

Read Point: Store #23 Dock #2

Read Point: Store #23 Interior Door #1

Product entering sales floor: Read point = Store #23 Interior Door #1 Business location = Store #23 Front Room

Product returning to storage: Read point = Store #23 Interior Door #1 Business location = Store #23 Back Room

EPCIS Business Step

• Business Step - specifies the business context of an event: What business process step was taking place when the event was captured?

• A Business Step answers the question: “What business process was being executed during this

event?”

Example: “Receiving”

EPCIS Disposition

• Disposition - specifies the business condition of the object subsequent to the event. The disposition is assumed to hold true until another event indicates a change of disposition.

• Disposition answers the question “What is the status of the product subsequent to the event?”

Example: “Available for Sale”

Other EPC Capture standards

Reader Management•Protocol for monitoring of RFID reader status•DO / SET / GET commands issued to and confirmed by reader

Low Level Reader Protocol (LLRP)•Defines interface between client and reader•Enables execution of air interface commands (e.g., read/write, lock, etc.)

Discovery, Configuration and Initialisation (DCI)•Protocol for automatic addition of RFID readers to a running system•Uses IETF Control & Provisioning of Wireless Access Points (CAPWAP)

Application Level Events (ALE)•Reduces volume of data from readers to applications•Insulates applications from device details
