Configuration

Transport Server Setup

Before configuring the plugin, ensure transport servers are properly configured:

1. Go to Administration > SFTP Servers
2. Click "Add a new SFTP server" or "New FTP server"
3. Fill in the connection details:
   • Server name: A descriptive name for the server
   • Host: The server hostname or IP address
   • Port: Connection port (default 22 for SFTP, 21 for FTP)
   • Username: Login username with read access to MARC files
   • Password: Login password (stored securely)
   • Download directory: Directory path on remote server containing MARC files
4. Test the connection to ensure it works
5. Save the configuration

Import Batch Profile Setup

Create or configure import batch profiles that define how MARC records are processed:

1. Go to Cataloging > Stage MARC records for import
2. Upload a MARC file to allow the creation of an import profile
3. Configure the import settings:
   • Record type: Biblio, Authority, or Holdings
   • MARC format: ISO2709 or MARCXML
   • Character encoding: UTF-8, MARC8, etc.
   • MARC modification template: Optional template to modify records during import
   • Record matching rule: How to match incoming records to existing ones
   • Actions: What to do with matches, non-matches, and items
4. Add a Profile name and click 'Save the profile'

Plugin Configuration

Configure the plugin to connect transport servers with import profiles:

1. Go to Tools > Automate MARC Import (under Plugins section)
2. Click "New Automate MARC Import Setting"
3. Configure the automation rule:
   • Transport server: Select the configured SFTP/FTP server
   • Import profile: Select the batch profile to use for files from this server
   • Filename patterns: Optional patterns to match specific files (one per line)
     • Leave blank to process all supported MARC files from the server
     • Examples: daily_update, weekly_marc, vendor_export, ebooks
     • Patterns are matched as substrings (case-insensitive)
   • Auto-commit: Enable to automatically commit staged records (bypass manual review)
   • Framework options (when auto-commit is enabled):
     • New record framework: Bibliographic framework to use for newly created records (default: Default framework)
     • Replacement record framework: Framework to use when overlaying existing records
       • "Keep original framework" preserves the existing record's framework
       • "Default" uses the system default framework
       • Or select a specific framework
4. Save the setting
5. Repeat for additional transport servers/profiles as needed

Archive Retention Settings

Configure archive retention to manage disk space:

1. Go to Plugins > Manage Plugins
2. Find "Automate MARC Import" and click Configure
3. Set the Archive retention count:
   • Default: 10 files per import setting
   • Maximum: 100 files
   • Set to 0 to disable archiving (files deleted after processing)
4. Click "Save Configuration"

Note: Each import setting has its own archive directory (Archive/{setting_id}/). The retention count applies independently to each setting's archive. When the limit is exceeded, the oldest files are automatically deleted.

Usage

Nightly Automated Processing

The plugin runs automatically as part of Koha's nightly cron jobs:

1. Connection: Connects to each configured transport server
2. File Discovery: Lists files in the configured download directory
3. File Filtering: Identifies supported MARC files (.mrc, .mrcx, .xml, .marcxml)
4. Deduplication: Skips files that haven't changed since last run or are duplicates
5. Download: Retrieves new MARC files to local storage
6. Staging: Parses and stages MARC records using configured profiles
7. Optional Commit: Automatically commits records if auto-commit is enabled
8. Archiving: Moves processed files to per-setting archive directory
9. Retention: Deletes oldest archived files when retention limit is exceeded
10. Cleanup: Removes temporary files

Manual Review Workflow (When Auto-Commit Disabled)

When auto-commit is disabled, staged records require manual review:

1. Notifications: Check the main staff page for alerts about staged files
2. Review Staged Batches: Go to Cataloging > Manage Staged MARC Records
3. Inspect Records: Review imported records, check for errors or issues
4. Resolve Duplicates: Handle record matches according to configured rules
5. Commit or Revert: Commit valid records or revert the batch if needed

Common Workflows for Librarians

Monitoring Daily Vendor Updates

• Configure transport servers for each vendor providing MARC updates
• Set up filename patterns to match daily/weekly update files
• Use auto-commit for trusted, high-quality vendor data
• Monitor staff interface notifications for any staging issues
• Review committed records periodically to ensure data quality

Managing Multiple Data Sources

• Create separate import profiles for different types of records (biblio, authority, holdings)
• Use filename patterns to route files to appropriate profiles
• Configure different overlay rules for different data sources
• Set up separate transport servers for different vendors or data feeds

Quality Control and Error Handling

• Disable auto-commit for new data sources initially
• Review staged records for data quality and consistency
• Check MARC modification templates are working as expected
• Monitor logs for parsing errors or connection issues
• Use the archive directory to review processed files if needed

Common Workflows for Administrators

Setting Up New Vendor Connections

• Obtain connection credentials from vendors
• Configure transport server settings in Koha
• Test connections and file access permissions
• Create appropriate import batch profiles
• Configure plugin rules with appropriate filename patterns
