EPC Information Services (EPCIS)

• A ratified EPCglobal standard • since April 2007

• Industry and Application Neutral

• Also supports non-EPC identifiers

• EPCIS Interfaces• EPCIS Capture Interface• EPCIS Query Interface

EPCIS –Introduction, Presented at Paris JAG Meeting in 2007


Fosstrak (formerly Accada)

Free and Open-Source Software for Track and Trace

Objective:• Provide core components for EPC Network applications

• Educate EPC Network users

• Drive adoption

Initiated by the Auto-ID Lab Switzerland / ETH Zurich, but it is today an independent open source effort

Contributions from Cambridge and MIT Auto-ID Labs


Fosstrak EPCIS is EPCglobal Certified


Fosstrak Usage Scenarios

• Embed our EPCIS Repository into your own applications to add an EPCIS interface to it

• Interactively explore any EPCIS Repository using our graphical EPCIS Query Application

• Use our EPCIS accessing applications as a blueprint to build your own EPCIS Capture or Query Application


Discovery Services (DS)

“Discovery”=

Finding and obtaining all relevant EPCIS data…

…to which a party is authorized,…

…when some of that data is under control of other parties

with whom no prior business relationship exists

A shared indexing service helps each party find its data

Similar to Internet search engine...but with pro-active

publishing, authentication and granular access control

policies, so you keep control of your data


Comparison between the World Wide Web & EPC Network

Purpose WWW EPC NetworkPrimary key for searching for information

Keyword Identifiers

Provides detailed information Website EPCIS

Locates a particular information resource

Website address Address of EPCIS

Authoritative system that routes requests

DNS ONS

Retrieve and show human-readable information

Web Browser Applicationsoftware

Locates new sources of relevant information

Crawling/indexing by search engines

EPCIS ‘publish’ arecord to a DS

Source “High level design for Discovery Services” BRIDGE WP2 1.3


ONS vs Discovery Services

Object Naming Service (ONS) Discovery Services (DS)

Pointers to services designated by the creator of an EPC class

Pointers services designated by any organization that claims to hold information on a specific serialized identifier

• Currently only GS1 identifier

• Class-level EPC identifier

• Identifier agnostic

• Serial-level identifiers

• Anonymous clients query • Authenticated and authorized clients query

• Authenticated brand owners publish (authoritative)

• Any authenticated resource owners publish (facilitative)

DS Use Case Scenarios

• Surgical Product Recall• notify subscribers currently holding the product

• Network Centric Pedigree• integration of horizontal supply chain participants

• Logistics Providers• sharing traceability data with multiple levels of subcontracting

• Consumer Electronics • reverse supply chains and third party service providers

• Tire Tracking• data sharing between fleet operators and manufacturers

• Farm-to-fork Traceability

33


Requirements gathering phase has completed

EPCglobal DS SAG work group began working in February 2010

The modules include:• Assertion Management (Authentication)

• Policy Management (Authorization)

• Record Management (Resource Registry)

Drafting of DS specification now in progress

Community Review Draft (aka LCWD) due end of 2011

Discovery Services Ratification
