Content, versions, and licenses

Knowspread separates content as an abstract course from the way that content is available in a concrete company space.

Entities

Entity	Role
Content	Logical course or another content type.
ContentVersion	Concrete version of content with lessons, steps, and metadata.
ContentInCompanySpace	Availability of content in a concrete space.
ContentLicense	Consumed license for a user and content in a space.
Marketplace::Offer	Content offer for other spaces or the public marketplace.

Content types

The current model supports:

• course,
• test,
• document,
• blended_learning,
• source,
• course_approval_request,
• external_certificate.

Ownership

ContentInCompanySpace distinguishes:

Value	Meaning
original	The space owns or created the content.
bought	The space received the content from an offer or marketplace.

active_version_number says which version the space currently accepts as active. For purchased content, it affects which versions the client can use.

Version upgrades

If there is an active version with a higher number than the space has in active_version_number, the content is upgradeable. This does not automatically mean all existing study records should be rewritten.

Licenses

A license is counted for the pair:

• UserInCompanySpace,
• ContentInCompanySpace.

Own content can have unlimited total licenses. Purchased content derives availability from accepted offers and already consumed licenses.
