Add Datacite types and properties to HDO

Problem

I would like to complete the mapping of the datacite schema to schema.org, however I cannot find appropriate types and properties in other ontologies. I was wondering if the HDO would be a suitable place the missing entities.

Backround-Info

The datacite commons API provides metadata in json (compliant with the datacite schema) and in json-ld (schema.org). However the mapping from datacite to schema.org ist incomplete. That results in the loss of information when data is requestet in json-ld.

The GBV (Gemeinsamer Bibliotheksverbund) terminology service provided a namespace to datacite entities and defined them via skos. Therefore it possible to add datacite-resource-types via @type or schema:additionalType to any (incomplete) schema.org mapping. However the GBV defined all datacite resources as skos:Concept or skos:ConceptScheme even datacite relation types, which makes it impossible to model relationships between nodes with datacite context.

The most important missing property is datacite:Collects / datacite:IsCollectedBy. Which relates a dataset to an instrument. Missing datacite resource types (such as datacite:Instrument) are annoying but not as problematic as missing relation types since there is a default resource type which is schema:CreativeWork.

Mapped relation types:

datacite:IsIdenticalTo => schema:sameAs
datacite:IsPartOf => schema:isPartOf
datacite:HasPart => schema:hasPart
datacite:IsPreviousVersionOf => schema:predecessor_of
datacite:IsNewVersionOf => schema:successor_of
datacite:References => schema:citation
datacite:HasTranslation => schema:workTranslation
datacite:IsTranslationOf => schema:translationOfWork

Missing realation types:

datacite:IsCitedBy / datacite:Cites
datacite:IsSupplementTo / datacite:IsSupplementedBy
datacite:IsContinuedBy / datacite:Continues
datacite:IsPublishedIn / datacite:IsReferencedBy
datacite:References
datacite:IsDocumentedBy / datacite:Documents
datacite:IsCompiledBy / datacite:Compiles
datacite:IsVariantFormOf
datacite:IsOriginalFormOf
datacite:HasMetadata / datacite:IsMetadataFor
datacite:Reviews / datacite:IsReviewedBy
datacite:IsDerivedFrom / datacite:IsSourceOf
datacite:Describes / datacite:IsDescribedBy
datacite:HasVersion / datacite:IsVersionOf
datacite:Requires / datacite:IsRequiredBy
datacite:Obsoletes / datacite:IsObsoletedBy
datacite:Collects / datacite:IsCollectedBy

Missing data types

datacite:InteractiveResource => nil
datacite:Instrument
datacite:Model => nil
datacite:OutputManagementPlan => nil
datacite:PhysicalObject => nil
datacite:Preprint => nil
datacite:Standard => nil
datacite:StudyRegistration
datacite:Workflow => nil

Mapped data types

datacite:Audiovisual => schema:MediaObject
datacite:Book => schema:Book
datacite:BookChapter => schema:Chapter
datacite:Collection => schema:Collection
datacite:ComputationalNotebook => schema:SoftwareSourceCode
datacite:ConferencePaper => schema:Article
datacite:ConferenceProceeding => schema:Periodical
datacite:DataPaper => schema:Article
datacite:Dataset => schema:Dataset
datacite:Dissertation => schema:Thesis
datacite:Event => schema:Event
datacite:Image => schema:ImageObject
datacite:Journal => schema:Periodical
datacite:JournalArticle => schema:ScholarlyArticle
datacite:PeerReview => Review
datacite:Report => schema:Report
datacite:Service => schema:Service
datacite:Software => schema:SoftwareSourceCode
datacite:Sound => schema:AudioObject
datacite:Text => schema:ScholaryArticle
datacite:Other => schema:CreativeWork

not part of DataCite schema, but used internally

datacite:Periodical => schema:Periodical
datacite:DataCatalog => schema:DataCatalog
datacite:Award => schema:Grant
datacite:Project" => schema:Project

This is what I found so far in my research:

An ontology that might work:

DISCO "A vocabulary for publishing metadata about data sets (research and survey data) into the Web of Linked Data"
