- Only store `url` field in `remote_url` extra if this is an URL otherwise store it in `ckan:source` [30](https://github.com/opendatateam/udata-ckan/pull/30)
- Properly handle geometry errors [31](https://github.com/opendatateam/udata-ckan/pull/31)
- Improve extras parsing [32](https://github.com/opendatateam/udata-ckan/pull/32):
- Skip empty extras
- Parse update frequencies as RDF URI or udata frequency identifier
- Parse `spatial-text` matching a known zone name or slug
- Store unknown `spatial-uri`, `spatial-text` and `frequency` as `ckan:spatial-uri`, `ckan:spatial-text` and `ckan:frequency`
