Archive proposals to enhance Schema.org accepted and published

Hi all,

I am pleased to announce that the latest release of the Schema..org
vocabulary (3.5) was launched today. It includes our proposals for archive
specific terms. There were a few minor alterations as part of the process
but in essence it is our proposal.


Specifically:

   - ArchiveOrganization <https://schema.org/ArchiveOrganization> - A new
   type that identifies 'An organization with archival holdings'

   - ArchiveComponent <https://schema.org.org/ArchiveComponent> - A new
   type that can be applied to any archive content, collection or item.

   - archiveHeld <https://schema.org/archiveHeld> - A property for
   *ArchiveOrganization*. Collection fonds or item held, kept, or
   maintained by an *ArchiveOrganization *Inverse of holdingArchive.

   - holdingArchive <https://schema.org/holdingArchive> - A property for
   *ArchiveComponent*. ArchiveOrganization that holds keeps or maintains
   the *ArchiveComponent.  *Inverse of *archiveHeld.*

In a separate proposal relevant to our group two more properties have been
added to the vocabulary:

   - collectionSize <https://schema.org/collectionSize> - Added to the
   Collection <https://schema.org/Collection> type  to indicate the number
   of items in the collection.

   - materialExtent <https://schema.org/materialExtent> - Added to the
   CreativeWork <https://schema.org/CreativeWork> type (and therefore its
   subtypes). 'The quantity of the materials being described or an expression
   of the physical space they occupy.'  This can be defined as either a simple
   string or a detailed quantified value and measurement type using the
   QuantitativeValue <https://schema.org/QuantitativeValue> type.

Also some new *CreativeWorks* subtypes suggested by the bibliographic folks
may come in handy when describing things in archives: Manuscript
<https://schema.org/Manuscript>, Poster <https://schema.org/Poster>, Drawing
<https://schema.org/Drawing>, SheetMusic <https://schema.org/SheetMusic>,
ShortStory <https://schema.org/ShortStory>, and Play
<https://webschemas.org/Play>.

All these, new in version 3.5, terms are held in the 'pending' section of
the vocabulary.  This is normal practice and over time they will move out
of that section.  Being in pending does not mean that a term should not be
used.  In practice, the more a term is used, the sooner it will move out of
pending.
