Propose new type CreativeWork

[ljgarcia]

Internal reference

No open issue related to this PR

Description

• Creates new type CreativeWork so we can add properties needed for various types of research artifacts, e.g., training resources, software

Motivation and context

Rather than having many types/profiles repeating similar or same properties, we put them at CreativeWork level

Have these been tested?

• Not really tested but based on observations from various hackathons

What should reviewers focus on?

• see if the properties are generic enough and make sense for various types of research artifacts
• see if having named properties nextItem and previousItem works better as extending a second type ListItem. We decided for named properties to add the inverse property feature (which is not in schema.org)

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New content (non-breaking change which adds new content)
• Modified content (non-breaking change which modifies existing content)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Future TO-DOs

• Once reviewed, create web page for this new type
