Harmonisation

other languages [de / es / fr]

The OpenDataMonitor harvests the metadata from all registered catalogues and harmonizes the largely inconsistent entries. Thus, the harvested metadata cannot be directly analysed and visualized. Therefore, initially the spelling of various formats and licenses needs to be harmonised and standardised. Subsequently, the different formats and licenses can be mapped to higher-level groupings, for example license schemas like creative commons.

To see the mappings and help improve them go to the harmonisation dashboard.

Harmonisation Dashboard

Harmonisation Dashboard

On the harmonisation dashboard you can examine the harmonisation history for all harmonised catalogues and view and add harmonisation rules. If you want to examine the harmonisation history for a particular catalogue, chose it from the list and click “view info”

You will then see the harmonisation history for various fields, inter alia licenses, formats etc.

If you want to improve the mappings, go to the “View/Add rules tab.

View/Add Rules

Choose what you want to inspect and for which catalogue and click view mappings. You will then see the list of harvested entries that have not been mapped as well as those that already have been mapped and what they are mapped to.

This are not the harvested raw data. These have already been harmonised and standardised to a unified in regard to spelling. Otherwise, the entries could not be meaningfully be mapped because of the sheer amount of different entries.

If you want to edit a rule or suggest a mapping for an unharmonised entry simply enter your mapping in the “value”-field on the right and save it. New rules will be reviewed and approved by an ODM administrator to ensure consistency within the ODM environment. Once approved, your rule will become part of the harmonisation process and be reflected on the ODM platform as well as its APIs.

If you would like to use these mappings for any other purpose you are free to try that. All components of the harmonisation engine have been published under a CC-BY 4.0-license and are available on github.
