VTLS is the first spin-off corporation from Virginia Tech

VTLS does business in 36 countries

VTLS has been working with RFID solutions for libraries for over eight years with many customers

VTLS RFID library management software is now RFID hardware and tag supplier independent.

Goals of NISO Working Group

• Identify specific NISO activities or standards that would make the application of RFID technology most effective for its community

• Identify related standards work where NISO might partner

• Identify points where RFID issues could be integrated within other NISO standards work

Page 5: Dr. Vinod Chachra Chairman, NISO Working Group on Library Applications of RFID CEO, VTLS Inc. A Report on NISOs work on RFID Standards in Libraries ALA.

NISO Working Group

Following types of organizations are participating in the working group:

1. RFID hardware manufacturers

2. RFID solution providers (software and integration)

3. RFID Library users

4. Book jobbers/ book processors

5. Other related organizations

Page 6: Dr. Vinod Chachra Chairman, NISO Working Group on Library Applications of RFID CEO, VTLS Inc. A Report on NISOs work on RFID Standards in Libraries ALA.

Focus of NISO Working Group

• RFID solutions run at several frequencies –

Low – from 125KHz to 134KHz

High – 13.56MHz

Ultra High – 860-960 MHz

Micro Wave – 2.45 GHz

• NISO’s work is limited to Tags used in libraries – that is, tags operating at 13.56 MHz

Page 7: Dr. Vinod Chachra Chairman, NISO Working Group on Library Applications of RFID CEO, VTLS Inc. A Report on NISOs work on RFID Standards in Libraries ALA.

Focus of NISO Working Group

Four issues of importance were identified:

1. Privacy Issues and concerns

2. Support of functional capabilities

3. Performance efficiency

4. Cost considerations (total cost of ownership)

Items 2 , 3 and 4 are linked and interdependent.

First of Two Objectives

Interoperability (from Whatis.com)

Interoperability (pronounced IHN-tuhr-AHP-uhr-uh-BIHL-ih-tee) is the ability of a system or a product to work with other systems or products without special effort on the part of the customer. Interoperability becomes a quality of increasing importance for information technology products as the concept that "The network is the computer" becomes a reality. For this reason, the term is widely used in product marketing descriptions.

Page 9: Dr. Vinod Chachra Chairman, NISO Working Group on Library Applications of RFID CEO, VTLS Inc. A Report on NISOs work on RFID Standards in Libraries ALA.

Visionary Technology in Library Solutions

First of Two Objectives

How is interoperability achieved? (whatis.com)

Products achieve interoperability with other products using either or both of two approaches:

• By adhering to published interface standards

• By making use of a "broker" of services that can convert one product's interface into another product's interface "on the fly”.

The first option is preferred.

Page 10: Dr. Vinod Chachra Chairman, NISO Working Group on Library Applications of RFID CEO, VTLS Inc. A Report on NISOs work on RFID Standards in Libraries ALA.

Visionary Technology in Library Solutions

First of Two Objectives

Interoperability

1. For RFID tags:

a. A tag from one library used in another (ILL)

b. Tags from different suppliers used in same library

c. Tags placed in materials by book vendors usable by library

2. For RFID Hardware:

a. Hardware from one vendor reads tags from another.

b. Security gates from one vendor reads tags from another

c. Sortation systems can handle tags from multiple sources

d. Secure data from one library not modified by another

3. Interoperability over time from same supplier

Second of Two Objectives

Isolation

• More specifically, Vertical Application Isolation

• We do not want CDs purchased at a store to trigger library security gates and library books to set off alarms at grocery stores.

• Application Family Identifiers (AFI) may be useful here

Approach taken by WG

• Examine existing standards; Adopt what can be adopted

• Examine existing data models

• Address the four issues previously mentioned keeping the objectives in mind

• Decide next step(s) if any.

Potential exposure from ILS

The Danish Data Model

It is an RFID data model for libraries. It deals only with materials and not with patron identification.

The data model has four parts:

1. Data elements

2. Values and range

3. Encoding and

4. Physical mapping.

Danish Model - Encoding

Original Recommendation:

“The encoding of RFID tags is a delicate job. The space available in a tag is still rather limited for the cost conscious buyer and vendor. …. Coding will with a few exceptions be 8 bit coding using ISO 8859-1 (latin 1)”

Final Recommendation:

“The working group has had long discussions on whether to choose ISO 8859-1 or UTF-8. The conclusion … UTF-8”

Danish Model – Data Elements

1. Metadata elements

2. Item data elements

3. Library data elements

4. Application data elements

5. Supplier data elements

A. Mandatory Data Block

Example: Version, Type of usage, Number of parts in item, part number, primary ID, CRC, Country, Owning library code

B. Structured Extension Data Block

C. Unstructured Extension Data Block

Page 26: Dr. Vinod Chachra Chairman, NISO Working Group on Library Applications of RFID CEO, VTLS Inc. A Report on NISOs work on RFID Standards in Libraries ALA.

Danish Model – Security

1. Using Application Family Identifier (AFI)a. Need two identifiers

b. One for “checked in” items and another for “checked out”.

c. This method is common to ISO 15693-3 tags.

2. Using non-AFI based methodsa. EAS bit method

1. Records a single bit on tag

2. Detection system checks code

3. If code indicates “checked in” alarm goes off

b. Other methods

3. Using either/both methods automatically means no interoperability

NISO WG and the Danish Model

• Copy of the data model is available on the internet

• NISO working group is now studying the data model to see if – The model meets the needs of USA RFID applications

– The models meets the needs of USA applications with some modifications

– A new model will have to be developed to meet our needs.

• Based on the outcome of the study a course of action for the future will be defined.

• The timetable for this is approximately six months – ending in April 2006.
