History Log is an Omeka plugin that logs creation, updates, deletion, import and export of Omeka items, collection and files and allows administrators to recall this information later.
This is not a replacement for your regular backups of the database, even if each each change is logged and each record can potentially be partially recovered at any time, except files. An undo button allows to recover the deletion of a record.
The logs are used by the plugin Curator Monitor, that computes statistics and allows to follow selected fields with limited vocabularies, for instance a special element "Metadata Status" with values "Incomplete", "Complete", "Fact Checked", "Ready to Publish" and "Published".
-
Logging
- If the plugin has not been installed with Omeka, older records will not have log entries and their stats will be partial.
- Logging is done via standard hooks. If a plugin bypasses the standard methods, some logs may be missing.
- Some standard methods don't use hooks, for example
deleteElementTextsByElementId(). They should not be used internally. Omeka uses them, but fires hooks anyway.
-
Recovering of a deleted record
- Records are recreated with the same id.
- It's recommended to undelete collections before their items.
- Files can't be recovered, but their metadata are logged, so they can be manually recreated as long as files are backuped.
- Non standard metadata are not saved and can't be recreated: status public or featured, item type, tags, flag "html" of element texts, etc. For the owner, the user who deleted the record is used.
- Check Omeka logs after a successful rebuild to see possible issues.
-
Export of logs
Logs can be filtered and exported via the main page of the plugin. Supported formats are:
- CSV, with values separated by a tabulation.
- OpenDocument Spreadsheet or "ods", the normalized format for spreadsheets, that can be open by any free spreadsheets like LibreOffice, or not free ones. This format requires that Zip to be installed on the server (generally by default).
- Flat OpenDocument Spreadsheet or "fods", another standard format that can be opened by any free spreadsheets or by any text editor (this is a simple xml file). Note: With old releases of LibreOffice for Windows, a little free filter may need to be installed.
If you use this plugin, please take a moment to submit feedback about your experience, so we can keep making Omeka better: see User Survey.
Uncompress files and rename plugin folder "HistoryLog".
Then install it like any other Omeka plugin.
Use it at your own risk.
It's always recommended to backup your files and database regularly so you can roll back if needed.
