## danZIG-vision (1)

- Establish the Danish libraries as an integrated network based on communication standards, where the user doesn’t need to know from which library system an information comes

- ZIG-tutorial 19.01.2000

- Leif Andresen

## danZIG-vision (2)

- Raise the functionality to a level, where all other electronic connection between library systems are rendered superfluous

- ZIG-tutorial 19.01.2000

- Leif Andresen

## danZIG-profile

- Level 0: basic bibliographic attributes like ONE-1 profile
- Level 1/Search: nearly all bibliographic attributes used in Denmark - incl. DAN-1 set
- Level 1: + Holdings and ILL-request and ILL status query

- ZIG-tutorial 19.01.2000

- Leif Andresen

**Notes:**
Level 0: 
basic bibliographic attributes like ONE-1 profile

Level 1/Search: 
nearly all bibliographic attributes used in Denmark - incl. our Danish DAN-1 attribute set. Including SCAN and danMARC2 format

Level 1: 
Level 1/Search: + Holdings and ILL-request and ILL status query

## ILL using Z39.50 (1)

- The simple one:
**Z39.50 Item Order**: An Extended Service with Request and response
- Can be in ISO ILL format

- ZIG-tutorial 19.01.2000

- http://www.nlc-bnc.ca/iso/ill/document/standard/z-ill-1a.pdf
- As defined in ISO 10161 !      All transactions from standard.

- Conditions for ILL corporation in Denmark:
- Denmark is one user community with 5 mio. inhabitants and 250 public libraries and 500 research libraries with public admission

- ZIG-tutorial 19.01.2000

- Leif Andresen

## Conditions (2)

- ILL-deliveries to Danish libraries:
- From Denmark to Denmark: 					95,4 %
- From Nordic countries:           				  1,7 %
- From rest of the world:           				   2,9 %

- ZIG-tutorial 19.01.2000

## Conditions (3)

- To Public Libraries   					871.000 units
- Of these: from Public Lib.				686.000 units

- ZIG-tutorial 19.01.2000

- Leif Andresen

## Conditions (4)

- 12 different library systems from 10 different system vendors
- Library system is a local decision
- Tradition for high level of corporation

- ZIG-tutorial 19.01.2000

- Leif Andresen

## Conditions (5)

- The Danish Union Catalogue **DanBib **has summary holding from nearly all Danish libraries
- DanBib mailbox facilities:
- ILL-request (ISO8459-1) format electronic and human
- A copy for own ILL-database

- ZIG-tutorial 19.01.2000

- Leif Andresen

**Notes:**
The Danish Union Catalogue DanBib has localisation from nearly all Danish libraries both Research libraries and Public libraries.

Existing DanBib mailbox facilities:
ILL-request in ISO8459-1 format electronic (or human readable) and a copy for own ILL-database 

## The integrated             ILL solution

- One session
- Update own ILL-database
- Check of holding
- Answer from target in same session
- Cover 95% of the requests

- ZIG-tutorial 19.01.2000

- Leif Andresen

**Notes:**
HEADLINES:

One session
Update own ILL-database
Check of holding before request
Point out holdings 
Answer from target in same session
Cover 95% of the requests

This solution is an alternative to a national central solution with all the ILL-transactions in one system.

## Working procedure (1)

- Search with Z39.50
- Present holdings with Z39.50                     using Holdings Schema
- ILL Request via Z39.50
- ILL Answer via Z39.50
- Both: Z39.50/ILL-profile 1

- ZIG-tutorial 19.01.2000

- Leif Andresen

**Notes:**
Search with Z39.50

Present holdings with Z39.50 using Holdings Schema.
As part of this present a unique identifier.

ILL Request via Z39.50 using the unique identifier from Holdings to identifikation of requested item.

ILL Answer via Z39.50 

Both: Z39.50/ILL-profile 1

## Working procedure (2)

- Working procedure after request
- Status request:
-                   STATUS-QUERY
- Response from task database of the target :  STATUS-OR-ERROR-REPORT

- ZIG-tutorial 19.01.2000

- Leif Andresen

## Unique identifiers

- Bibliographic record:
- 			TargetLocationId
- Multivolume part:
- 			TargetBibPartId
- Journal item: 					TargetPieceId

- ZIG-tutorial 19.01.2000

- Leif Andresen

**Notes:**
From Holdings Schema and used as systemnumber in ILL-request

OBS. TargetCopyId skal undersøges nærmeren - Gatenby påpegede at den svarer til subscription/abn.
Relevant indvending

## The Future

- The next step of danZIG-profile will include most of the ILL-transactions
- And specifications for how to use the transactions

- ZIG-tutorial 19.01.2000

- Leif Andresen

**Notes:**
Items for discussion:

- User interfaces to ILL-modules in different library systems (outside the scope of danZIG - discussed with ILL-librarians)

- How to handle transactions after request and status-query? Discussed with Danish groups for ILL-librarians. But  focus for danZIG  is: communication library system to library system - not librarian to system.

But this is the mains topic for a corporation with two groups of ILL-librarians. The result of this work will be specifications for a high level of automation of the local ILL-work. E.g. intelligent handling of answers to status requests: nothing is the user will wait for the book - a message to user if "last date" will be passed.
