Blank nodes

[SamiNorling]

Blank nodes are allowable where for attributes that are not themselves entities. This includes:

• Timespans
• Dimensions
• Values/Monetary Amounts
• etc.

Essentially, if an element would not need to be referenced by multiple sources, it does not need a dereference-able URI.

Need to update the transformation logic, tracking spreadsheet to no longer create URIs for:

• Dimensions
• Production Timespans
• Check for other elements that don't need URIs.

Discussed in Issue #166 in the main Linked Art repository.

Conclusion: CAN use blank nodes, but SHOULD use URIs where possible. You MUST use URIs if the resource is a top-level resource according to the API specs [TBD].

Decision for IMA: will avoid blank nodes when possible, but in cases where resources do not have their own unique identifiers in CMS (e.g., no identifiers for individual dimensions within the dimensions table; alternative names in the names table; etc.), will use blank nodes instead of minting URIs based on non-fixed characteristics (e.g., order within the table) or finding a way to manage URIs within or outside of the CMS.
