|Subject||[greenstone-users] Problems exploding CDS?ISIS for Windows databases|
After experiencing problems moving large databases from CDS/ISIS to Greenstone I downloaded the latest version of the software and started again. I have noticed the following problems.
1) When we tried to explode one of ISIS databases containing links to images, the error 'out of memory can not parse metadata.xml' occurs. With the assistance of one of our I.T. consultants we have realized that the size of the produced metadata file in the import folder affects the successful execution of the next stage of the import, which is to parse that file into individual XML files and folders. For example, the failed metadata.xml file is 17,000 KB.
2) In trying to build another Greenstone collection from a large ISIS database in the MARC format (this one is purely bibliographic without links to digital files), the import stops at 1828 each time. The database contains 10,000+ records.
The procedure I have used is - I would select Dublin core metadata set and then select explode metadata. I am then requested to either ADD, MERGE or IGNORE individual fields in the MARC record. I then merge some fields with Dublin core and add others as additional DC elements. I am wondering if there is a limit to the number of DC elements which can be added?
Is there anyone out there who might have experienced similar problems?
