Offer download as MARC21 option #733

Open kouralex opened 6 years ago

It'd be great if one could download a concept in MARC21 format. However, one has to keep in mind that because MARC21 has some limitations in its format it will be impossible to map all the linked data properties, resulting in data loss. Also, a discussion/guideline is needed to determine the proper mappings of properties. @jarmosaarikko @osma

I think the conversion to MARC is outside the scope of Skosmos and should be handled with a separate tool. What Skosmos could do is to offer download of the whole vocabulary as MARC, just like it currently provides Turtle and RDF/XML if these have been configured using void:dataDump in vocabularies.ttl. Skosmos could simply recognize the .mrc and/or .mrcx extensions in void:dataDump and provide download links to those as well. These go via the REST API, so the API needs to be aware of those formats as well.

I think providing MARC for a single concept is out of scope for now. The whole vocabulary as MARC is more important so let's start with that.

Good points. In fact, I just realized it is not possible to convert all linked data concepts to meaningful MARC anyways. I guess this should, thus, be a vocabulary specific feature with a possible configuration file for the conversion.
