Structured Data - Change History & Alerts

Added support for Certifications and a few smaller updates:

• Added Certification to allow the specification of certifications for places, organizations, products, and persons. Compatible with gs1:CertificationDetails.
  
• Added colorSwatch.
  
• Added KeepProduct for ReturnMethodEnumeration.
  

Added vocabulary for describing types of digital sources (in collaboration with IPTC), and clarifying subtypes of Physician:

• Added IndividualPhysician, PhysiciansOffice as subtypes of Physician to clarify the longstanding ambiguity between these two different interpretations of the Physician type. Amended occupationalCategory to be applicable here and added usNPI for use with NPI identifiers in the US.
  
• To help address situations around the responsible use of generative AI, we add a "digital source type" vocabulary based on IPTC's definitions. This consists of a property digitalSourceType, an enumeration type IPTCDigitalSourceEnumeration, and a set of 14 coded values such as TrainedAlgorithmicMediaDigitalSource mapping directly to the IPTC list.
  

A collection of small fixes based on publisher feedback:

• Added agentInteractionStatistic to provide a way of counting interactions where the item of interest is in an "agent" rather than "object" role on the relevant Action.
• Provided a clearer way to indicate non-Comment items that Comments are attached to, by documenting the use of parentItem on CreativeWork in general. Also made it more explicit that this is especially applicable to those creative works beneath Comment in the type hiearchy which are mentioned in the definition, i.e. Question and Answer.
• Added Comment to the domain of sharedContent to better support link shares on replies/comments even though a lot of sites now support this.
• Expanded range of uploadDate to include DateTime, correcting a longstanding bug.
• Improved error reporting in case the parsing of JSON-LD examples fails.
• Improvements to unit-testing code.
• Fixed all RDF comments that did not finish with a punctuation. Plus improved reporting of these.
