# DBLP XML SCHEMA - Recent Changes

## October 17, 2023

* Changed content and type of dblp:monthOfPublication to xsd:gMonth

  The optional data field dblp:monthOfPublication did carry a descriptive
  xsd:string literal. This has now been translated to a xsd:gMonth. Please
  note that there is a number of descriptive strings in dblp that do not
  match properly to a month; those values are now ommitted.

* Deprecated dblp:orderedCreators property

  The use of rdf:List was cumbersome when using this property in queries,
  and we needed a way to add additional metadata to the publication-creator
  link. Hence, we are dropping dblp:orderedCreators in favor of the
  dblp:hasSignature property and the new dblp:Signature entities.

* Added dblp:Signature, dblp:AuthorSignature, dblp:EditorSignature classes
  and dblp:hasSignature property

  Those new entities represent the attribution link from a publication to a
  single creator. E.g., if a paper has four authors listed, then the
  dblp:Publication is linked to four dblp:Signature entities. Each signature
  is linked to exactly one dblp:Publication and one dblp:Creator, and may
  list further metadata of the link, like the (mandatory) ordinal of
  the signature (i.e., n for the n-th author listed on the paper) or an
  (optional) ORCID listed for that particular linked creator.

* Extended the domain of dblp:webpage, dblp:archivedWebpage, and
  dblp:wikipedia to dblp:Entity

  We made this change to cover all external website links for all different
  entities in a more general manner.

* Renamed dblp:electronicEdition to dblp:documentPage and
  dblp:primaryElectronicEdition to dblp:primaryDocumentPage, and
  deprecated dblp:archivedElectronicEdition

  We moved the dblp:Publication resource links under the general umbrella
  of dblp:webpage. At the same time, we renamed the external links for
  publications for clarity, and we removed dblp:archivedElectronicEdition
  since this is already covered by dblp:archivedWebpage.

* Renamed dblp:fullCreatorName to dblp:creatorName, and
  dblp:primaryFullCreatorName to dblp:primaryCreatorName

  Those properties were cumbersome to use in queries, so we shortened them.

* Deprecated dblp:otherFullCreatorName, dblp:otherAffiliation,
  dblp:otherHomepage, dblp:otherElectronicEdition properties

  The use of the dblp:other* properties were impractical when using in
  queries. Hence, we are dropping dblp:otherFullCreatorName,
  dblp:otherAffiliation, dblp:otherHomepage, and dblp:otherElectronicEdition
  in favor of the parent properties dblp:creatorName, dblp:affiliation,
  dblp:homepage, and dblp:documentPage.
