Re: [dxwg] Primary and alternative identifier [RIDALT] (#67)

Following from discussions in #53 and @riccardoAlbertoni's proposal in the [wiki](https://github.com/w3c/dxwg/wiki/DCAT-Identifiers), neither [Dublin Core](http://dublincore.org/documents/dcmi-terms/) nor [ADMS](https://www.w3.org/TR/vocab-adms/#identifier) have terms to represent alternative identifiers. 

In DATS we followed [DataCite](http://schema.datacite.org/meta/kernel-4.1/metadata.xsd) approach by having a representation of: [primary identifier](https://github.com/datatagsuite/schema/blob/master/identifier_info_schema.json), [alternate identifiers](https://github.com/datatagsuite/schema/blob/master/alternate_identifier_info_schema.json) and [related identifiers](https://github.com/datatagsuite/schema/blob/master/related_identifier_info_schema.json).
