Proposal for Periodicals, Articles and Multi-volume Works

Description

This proposal is intended to enable basic description of Articles within issues and/or volumes of periodicals of most types - Scholarly journals, magazines, comics, etc. The proposal also will enable the description of multi-volume works (e.g. the three volumes that make up Lord of the Rings).

As a basic proposal it does not address the full description of periodicals as stand-alone entities, and avoids any explicit statement of hierarchy in the parts that make up a periodical.

It proposes three new Types: Periodical, PublicationVolume, PublicationIssue, and added properties for two existent Types: Article, CreativeWork. It also proposes the Blog type is repositioned in the hierarchy below the proposed Periodical.

The discussions behind these proposals was informed from several sources with the Bibliographic Ontology (bibo) deserving specific mention.

New Type: Periodical

A publication in any medium issued in successive parts bearing numerical or chronological designations and intended, such as a magazine, scholarly journal, or newspaper to continue indefinitely.

Type hierarchy

  • Thing > CreativeWork > Periodical

Properties for Periodical

  • issn (Text) The International Standard Serial Number (ISSN) that identifies this periodical. You can repeat this property to (for example) identify different formats of this periodical.


New Type: PublicationVolume

A part of a successively published publication such as a periodical or multi-volume work, often numbered. It may represent a time span, such as a year.

Type hierarchy

  • Thing > CreativeWork > PublicationVolume

Properties for PublicationVolume

  • volumeNumber (Text) Identifies the volume of publication or multi-part work; for example, "iii" or "2".
  • pageStart (Text) The page on which the work starts; for example "135" or "xiii".
  • pageEnd (Text) The page on which the work ends; for example "138" or "xvi".
  • pagination (Text) Any description of pages that is not separated into pageStart & pageEnd; for example, "1-6, 9, 55" or "10-12, 46-49".


New Type: PublicationIssue

A part of a successively published publication such as a periodical or publication volume, often numbered, usually containing a grouping of works such as articles.

Type hierarchy

  • Thing > CreativeWork > PublicationIssue

Properties for PublicationIssue

  • issueNumber (Text) Identifies the issue of publication; for example, "iii" or "2".
  • pageStart (Text) The page on which the work starts; for example "135" or "xiii".
  • pageEnd (Text) The page on which the work ends; for example "138" or "xvi".
  • pagination (Text) Any description of pages that is not separated into pageStart & pageEnd; for example, "1-6, 9, 55" or "10-12, 46-49".


Type: Article

New Properties for Article

  • pageStart (Text) The page on which the work starts; for example "135" or "xiii".
  • pageEnd (Text) The page on which the work ends; for example "138" or "xvi".
  • pagination (Text) Any description of pages that is not separated into pageStart & pageEnd; for example, "1-6, 9, 55" or "10-12, 46-49".


Type: CreativeWork

New Properties for CreativeWork

  • isPartOf (CreativeWork) A related CreativeWork (for example: collection, gallery, publication, or multi-part work) in which this is either logically or physically included.
    • Note this proposal recommends the promotion of isPartOf from WebPage to CreativeWork with the above adjusted description.
  • hasPart (CreativeWork) A related CreativeWork that is included either logically or physically in this CreativeWork; for example, things in a collection, parts in a multi-part work, or articles in a periodical or publication issue.


Type: Blog

A blog fits the description of a publication in any medium issued in successive parts bearing numerical or chronological designations to continue indefinitely, also some blogs have been allocated an ISSN. Moving Blog in the hierarchy to be a sub-type of Periodical would beneficially aid the description of blogs without any impact on previously created descriptions.

Type hierarchy

  • Thing > CreativeWork > Periodical > Blog


Relationship with other vocabularies

The following properties and classes should be considered equivalents (owl:equivalentProperty / owl:equivalentClass) in bibo:

  • schema:issueNumber -> bibo:issue
  • schema:issn -> bibo:issn, bibo:eissn
  • schema:pageStart -> bibo:pageStart
  • schema:pageEnd -> bibo:pageEnd
  • schema:pagination -> bibo:pages
  • schema:Periodical -> bibo:Periodical
  • schema:PublicationIssue -> bibo:Issue (volume property excepted)
  • schema:isbn -> bibo:isbn

Examples for Periodical, PublicationVolume, PublicationIssue, and Article

The following examples could be used on the schema:Periodical, schema:PublicationIssue, schema:PublicationVolume, and schema:Article documentation.

        The library catalog as a catalog of works
        was an infectious idea, which together with research led to
        reconceptualization in the form of the FRBR conceptual model. Two
        categories of lacunae emerge—the expression entity, and gaps in the
        model such as aggregates and dynamic documents. Evidence needed to
        extend the FRBR model is available in contemporary research on
        instantiation. The challenge for the bibliographic community is to
        begin to think of FRBR as a form of knowledge organization system,
        adding a final dimension to classification. The articles in the present
        special issue offer a compendium of the promise of the FRBR
        model.
