Designate "required" vs "optional" fields in template defintions?

[benloh]

How do we programmatically distinguish between the required fields and the optional "attribute" fields?

• isRequired is set in template, but not clear how consistently it's used. Mostly with .weight?

Built-in fields are currently defined in app/system/util/enum.js

Nodes

Required

• id
• label
• degrees
• created
• createdby
• updated
• updatedby
• revision

  Attributes/Optional (not required, can be removed or new ones added)

• type -- type:select
• notes -- type:markdown
• date -- type: 'date`

Edges

Required

• id
• source -- id number
• target -- id number
• weight
• degrees
• created
• createdby
• updated
• updatedby
• revision

  Attributes/Optional (not required, can be removed or new ones added)

• type -- type: select
• citation -- type: string

Use

Currently we use a filter to retrieve attributes fields from the full list of node definitions:

const attributes = Object.keys(nodeDefs).filter(
      k => !BUILTIN_FIELDS_NODE.includes(k)
    );
