FEP-888d: Using w3id.org/fep as a namespace for extension terms and for FEP documents

I’m reading through it and collecting my comments.

For example, we can consider the definition of “Public” addressing within ActivityPub, represented by the “Public” magic collection. When the normative ActivityStreams 2.0 context is applied, the IRI for this collection may be equivalently expressed as Public, as:Public, or https://www.w3.org/ns/activitystreams#Public.

This statement is untrue, but often made. Due to Public missing from https://www.w3.org/ns/activitystream, only as:Public expands to https://www.w3.org/ns/activitystream#Public. See Public is missing from https://www.w3.org/ns/activitystreams HTML page · Issue #531 · w3c/activitystreams · GitHub.

So please use another example.

		"exampleA": {
			"@id": "fep:9606/exampleA",
			"rdf:comment": "A term with some literal value (string, boolean, number)"
		},

The rdf:comment is invalid. See

An expanded term definition MUST be a map composed of zero or more keys from @id, @reverse, @type, @language, @container, @context, @prefix, @propagate, or @protected. An expanded term definition SHOULD NOT contain any other keys.

in 9.15.1 Expanded term definition.

I would also like to see some rules on naming here. For example, nobody should introduce a term “Twitter” as we do not hold the trademark. I think I adapted from did-core.

Some more thoughts

I currently feel that it would be wise to require examples for each term in the new context and then run:

expanded = json_ld.expand(example)
recompacted = json_ld.compact(expanded, example["@context"]) 

assert recompacted == example

This would guarantee that the new context is valid. Furthermore, these examples will serve to explain the authors thinking. If one uses a build process for FEP documents, one can use this to include the examples in the FEP document.

I actually don’t have a strong preference of this FEP vs FEP-2e40: The FEP Vocabulary Extension Process. Now that I understand what is necessary. Of course, this means that all FEPs introducing Vocabulary terms need to be in the new folder format.
