  1. maintainers : A maintainer of a Dataset, SoftwareApplication, or other CreativeWork. A maintainer is a Person or Organization that manages contributions to, and/or publication of, some (typically complex) artifact. It is common for distributions of software and data to be based on "upstream" sources. When maintainer is applied to a specific version of something e.g. a particular version or packaging of a Dataset, it is always possible that the upstream source has a different maintainer. The isBasedOn property can be used to indicate such relationships between datasets to make the different maintenance roles clear. Similarly in the case of software, a package may have dedicated maintainers working on integration into software distributions such as Ubuntu, as well as upstream maintainers of the underlying work.
  2. description : Allows for the description to be an array of nodes (e.g. an array of inline content, or a couple of paragraphs), or a string. The minItems restriction avoids a string being coerced into an array with a single string item.
  3. dateAccepted : This is not yet a property but the term is used in Dublin Core.
  4. issns : A periodical may have multiple ISSN (e.g. for online and print versions). See for more details.
  5. identifiers : Some identifiers have specific properties e.g the issn property for the Periodical type. These should be used in preference to this property which is intended for identifiers that do not yet have a specific property. Identifiers can be represented as strings, but using a PropertyValue will usually be better because it allows for propertyID (i.e. the type of identifier).
  6. title : Allows for the title to include inline content (e.g Strong, Math) or a string. The title can not be block content e.g Paragraph. The minItems restriction avoids a string being coerced into an array with a single string item.
  7. version : In this case string is listed as an alternative before number to avoid semantic version numbers e.g. 1.0 being parsed, and subsequently encoded, as 1 thereby resulting in loss of information.
  8. about : Consistent with, this property allows for linking to one of more Thing nodes. This could for example include a Person (e.g for a bibliography) or a DefinedTerm (e.g. for subject areas the creative work relates to).
  9. fundedBy : This follows the proposal here for a property that is the reverse of fundedItems. It is an any because a CreativeWork may have been funded through more than one Grant.
