Abstract Conversion tools are heavily used in libraries for data exchange. The advent of Internet has brought the concept of digital libraries. In Nepal, CDS/ISIS is mainly used to create bibliographic database. In recent years, years, with the trend of open source source software software and web based system, system, librarians librarians are moving towards web based system. However, exchanging exchanging data already created has created problem to move towards new system. MarcEdit is a tool which can be used for such conversion among databases. This paper is a tutorial for exchanging data between CDS/ISIS and MARC21 format of KOHA.
1. Introduction
Libraries maintain their Machine Readable Catalogue (MARC) in the form of databases. In most of the libraries of Nepal, Unesco developed developed CDS/ISIS database is used. The CDS/ISIS database supports fields and subfields. The bibliographic bibliographic data elements in the form of fields and subfields is known as MARC. The standard used in creating data entry form in CDS/ISIS is CCF (Common Communication Format). In KOHA (integrated library system), data entry form used is MARC21. The data entered into CDS/ISIS is not compatible with KOHA. A GUI (Graphic User Interface) I nterface) based third party tool MarcEdit is available available for such conversion. conversion. 2. Features 2.1 Editing of MARC Records MarcEdit includes Marc Tool which contains:
MarcBreaker MarcMaker Marc-MarcXML
MarcEdit provides a mechanism to edit MARC records. MARC records can be edited using any native editor. It converts native MARC format file to editable Mnemonic format using MARC tools or vis-a-vis using MarcBreaker and MarcMaker, respectively.

Fig. 2: Output file in Mneonic format
2.2 UNICODE Compatibility
MarcEdit is UNICODE compatible. It can convert MARC-8 records, which is native MARC format to code multilingual characters, i.e. to. UTF-8. It can read and wirte UNICODe code characters, thus Indic scripts can be used in data manipulation. But once the data is entered in UTF-8 it can't be changed to MARC-8 character set. 2.3 Import/Export
It can import and export records in MARC format. One can export any selected MARC records.

3. Procedure for CDS/ISIS to MARC21 format compatible to KOHA
3.1 Prepare conversion table. . Prepare CDS/ISIS=>MARC tag map file which will map ISO tags with MARC tags. For this open, notepad and type in the following format: ISO tags i.e. CDS/ISIS FDT (left side) =>MARC21 Tags on the right side as follows: 012=>111 024=>245 025=>250 026=>260 030=>300 044=>490 050=>500 069=>650 070=>100 071=>110 072=>111
2. Export in ISO -2709 Format:
Open CDS/ISIS database. Then choose option export. In the option separator, give the subfield separator sign (^) as shown below:
Fig 4: Export in ISO 2709 format Then click ok button. After completing the procedure in CDS/ISIS then open the MarcEditor.
Fig 5: MarcEditor Tool Click on Add-Ins and select the option Special Format Translator.
Fig6: Add-Ins option Click on the option (Special Format Translator) another window will be opened. Click on Next button.
Fig. 7: MarcEdit Special Translator MarcEdit Translation window will appear. Select the option CDS/ISIS to MARC and click on Next button Give the saved iso file path in new window as shown below. Select advance Translation option. Check all three options as shown in the following window.
Fig 8: MarcEdit Special Translator option Click on Advance Translation, which will show the following table
Fig. 9: Load Mapping
Click on load mapping and give the file name of tag mapping of CDS/ISIS =>MARC21. Tick all check boxes. Then click OK Now Click Process button of fig.8 and click close button of Fig. 9
Fig 9: Converted data screen
Open the the MARC Tools dialog. This can be accessed from two locations. The first by selecting
the File/MARC Tools option in the menu and the second by selecting the MARC tools Icon on the main screen (Fig. 10 below):
Fig 10: MARC Tools dialog box When the MARC tools Dialog open, the following option can be seen: MARC Tools Main Window MARC Breaker MARC maker MARC=>MARCXML MARC Editor Click on MARC Tools Main Window, which opens the following window:
Fig. 11: MARC Tools main window Click on MarcBreaker. In the Input file, write the location of the test.mrc created as per instruction given in fig 9. Fill the output file as test.mrk. Click on Execute.
Open MARCEditor and open test.mrk file created recently as given in Fig. 11. Then perform the following process: Click on Edit Click on Replace Put { in Find What and a space in Replace with Click Replace all Put } in Find What and a space in Replace with Click Replace all. Now Click on File of MarcEdit Click on Make Current File into MARC
Save the output as the finaldata. Now MARC data can directly be imported in to KOHA Reservior through the web interface. However, importing MARC data into KOHA throw Intranet Interface doe not create the biblio table within KOHA. To create biblio table you have to use the bulkmarcimport.pl scrript. The steps are as follows: Create directory inside /usr/local/src copy bulkmarcimport.pl and finaldata.mrk file just created into /usr/local/src/migrate Run bulkmarcimport.pl script as follows: [
[email protected]/]# ./bulkmarcimport.pl -d -file finaldata.mrk -n 1 The converted data will be shown as the record is converted. Then you are ready to use the converted data from KOHA with searching and editing facility.
