ckanext-metaexport

ckanext-metaexport proviedes universal way to export dataset's metadata into different metadata standards.

All formats should be registered before using. In order to do this, perform next steps:

1. Implement ckanext.metaexport.interfaces.IMetaexport interface.
2. Add register_metadata_format, that returns dictonary with format names as keys and FormatInstances as values.

3. Add dataExtractors - method that provides function for generating data, that'll be passed into templates. It can be done via register_data_extractors method, that receives current formatters list and should pick desired format from collection and call set_data_extractor of this format. set_data_extractor expects to receive one argument - function, that will receive package_id and should return dictonary with template variables. 5. In order to create your own format, you have to create class, inherited from ckanext.metaexport.formatters.Format

All export views are available under /dataset/{id}/metaexport/{format} URL.
