This page provides information to help those who are considering implementing CKAN as a platform for publishing records to Research Data Australia.
CKAN (Comprehensive Knowledge Archive Network) is a web-based open source system for the storage and publication of data. Its code base is maintained by the Open Knowledge Foundation and several Australian jurisdictions use the CKAN platform to publish data. These include:
CKAN crosswalk to RIF-CS
The ANDS harvester now provides support for harvesting CKAN records into Research Data Australia. CKAN's default metadata schema is converted (crosswalked) into RIF-CS, the metadata schema used in Research Data Australia. To create RIF-CS records, the crosswalk uses both metadata that is entered by human users and generated automatically by CKAN.
One RIF-CS Collection record is created for every CKAN record. In addition, one RIF-CS Party record is created for the Organisation that published the CKAN record, and one RIF-CS Party record is created for the CKAN Author or data authority. A RIF-CS Service record is constructed to represent either an API or a Web Service.
Complete CKAN records include metadata created and entered by humans and metadata automatically generated by CKAN itself. The information provided here describes how the human-created CKAN metadata is crosswalked into RIF-CS and provides recommendations about how to use the CKAN fields for best effect when the resulting record is presented in Research Data Australia.
Potential to customise the crosswalk
This crosswalk should be seen as a starting point. There is potential to customise it if you feel your CKAN records can be presented in Research Data Australia in a way that better suits your requirements.
CKAN metadata schema
The information provided here is based on the standard CKAN metadata schema. Some organisations choose to modify the schema. There is also potential to customise the schema to take advantage of information provided in a modified schema for improved presentation of records in Research Data Australia.
