V. 21. Automatic LKR field creation from item. Rep_ver 017011 and 017012

Yoel KortickAleph Support Manager

Introduction• Description: LKR creation from item. Cataloging - a way

to automatically fill the LKR filters according to specific item information. After entering existing item barcode, the LKR field will be filled with that item's information.

• In Addition, 245 $$a will be filled with z30 description.• The new menu item "Expand from Item" option will be

enabled only when LKR field is selected.

3

In other words …• Formerly (before version 21) when a cataloger created

an LKR field in the bibliographic library he had to manually fill in each of the many subfields of the LKR field, and constantly verify that he was putting in the correct information in each of the many fields (such as the volume number, issue number, administrative system number, etc)

• This is now all done automatically by entering the specific item barcode in the new dialog box.

4

The LKR sub fields• After entering existing item barcode, the LKR field will

be filled with that item's information, as follows:$$y<<item chronology level i >>$$j<<item chronology level j>>$$w<<item chronology level k>>$$o<<item chronology level l>>$$q<<item chronology level m>>$$v<<item enumeration level a>>$$i<<item enumeration level b >>$$p<<item enumeration level c>>$$d<<item enumeration level d>>$$e<<item enumeration level e>>$$f<<item enumeration level f>>$$g<<item enumeration level g>>$$h<<item enumeration level h>>

• In addition, 245 $$a is filled with z30 description.

5

“Expand from item barcode” menu option• The new menu item "Expand from Item" option will be

enabled only when LKR field is selected.

6

Sample Item in the web• We will now be cataloging an article which is in Journal

“Aleph 500 quarterly” Volume 7 issue 2 part 3

7

Sample Item in the GUI

It has: Barcode: 57097-500Enumeration Level A: 7Enumeration Level B: 2Enumeration Level C: 3Chron Level I: 2005

Sample Item in the Database

usm50@ALEPH20> set head off usm50@ALEPH20> set pause off usm50@ALEPH20> select Z30_ENUMERATION_A,Z30_ENUMERATION_B,Z30_ENUMERATION_C,Z30_CHRONOLOGICAL_Ifrom Z30where Z30_BARCODE = '57097-500';

The record with the LKR field

• Now we are cataloging an article which is in the journal.• Note that the record has no 245 field (has 246). • With mouse on LKR field choose “Expand from item barcode”

10

The record with the LKR field

• Enter the barcode of the desired item

11

The record with the LKR field

• The LKR field automatically gets filled in with the item information in the appropriate fields

• The 245 fields gets filled in with the item description.

12

The record with the LKR field

• The 245 may then be edited and additional fields added to the LKR field.

13

The record with the LKR field

• The record then contains a link to the item

14

The record with the LKR field

• Before version 21 all of the LKR enumeration and chronology sub fields would have had to added manually

Now these sub fields are added automatically

15

Additional LKR sub fields• Via rep_ver 17012 Aleph was enhanced to support

additional linking filters. These linking filters provide the ability to filter items according to all filtering levels of the item.

Version 20

Version 21

16

Additional LKR sub fields• The following LKR subfields are now also consulted when

filtering items:• $$d - Fourth level of enumeration• $$e - Fifth level of enumeration• $$f - Sixth level of enumeration• $$g - Alternative first level of enumeration• $$h - Alternative second level of enumeration• $$j - Second level of chronology• $$w - Third level of chronology• $$o - Fourth level of chronology• $$q - Alternative chronology.

17

Additional LKR sub fields• In order to enable the use of the additional sub fields in the

LKR field, the following developments were done:1. The LKR form in the PC GUI catalog module was enhanced to

include the additional subfields.2. Searching in WEB OPAC and PC GUI for documents will return

only the Items that match all defined subfields.

• In order to activate this development1. New Oracle table Z103X should exist2. Activate the extended linking routine

“update_z103_lkr_extended” in bib and adm tab/tab_z103

18

Additional LKR sub fields• Here the z103x table exists in file_list:

• Here the “update_z103_lkr_extended” exists in bib and adm tab/tab_z103

yoelk@il-aleph07(a21_7) USM01> cd $aleph_root/tab

yoelk@il-aleph07(a21_7) USM01> grep z103x file_list.BIB

19

Additional LKR sub fields• Here we have six issues, each with six levels of enumeration

Additional LKR sub fields• We will now “expand item from barcode” for

barcode 57097-540

23

Additional LKR sub fields• All of these subfields are automatically filled in

24

Additional LKR sub fields• Now we have these two bibliographic records with

LKR fields. • One points to $$g3 and one point to $$g2

25

Additional LKR sub fields• Here is system number 57109

• It points to correct item based on LKR subfields

26

Additional LKR sub fields• Here is system number 57108

• It points to correct item based on LKR subfields

27

Creation of the LKR field• Note that by default when a new record is created

via “Edit Actions > Derive new record” for the following two options:• Create Analytic record• Create Analytic record using fix_doc_new (son)

• An LKR field will already be created with subfields • a (link type)• b (sysno of the linked document record)

Creation of the LKR field

29

Creation of the LKR field• For example, here we have system number 57097

30

Creation of the LKR field

• It has item barcode 57097-570 with “2010 Vol. 3 Iss. 1 Pt.2 Sec. 1 Part 1 Div. 1 1st part”

31

Creation of the LKR field

• We choose “Derive new record > Create Analytic record using fix_doc_new (son)” and get this:

32

Creation of the LKR field

• When we choose “expand from item barcode” we also get this:

Creation of the LKR field

• We then edit and save the record

34

Creation of the LKR field

• In the web OPAC a link appears to the “father” record

• And a link appears directly to the specific item

35

Creation of the LKR field

• Link to the specific item
