Is the property syntax `?p` really necessary ?

[tfrancart]

I would try to avoid introducing the ?p property syntax.

1. A normal annotation could be placed on a markdown link, and in this case the URL value will be picked up in priority to create an object property

[NASA](https://www.nasa.gov/) {ex:org} is sufficient

2. If the annotation contains a reference to a URI with =, then the parser knows that an object property must be build, no need for a ?

[NASA] {=ex:nasa ex:org} is sufficient to know that we need to create an object property

The less specific syntax, the easier

Thanks for the proposal, but I use the annotation pattern that defines both the named node and a literal, like this:

# Article {=ex:article1 .ex:Article label}

## Section 1 {=ex:section1 .ex:Section label ?member}

And we need a distinction between the named node relation and literal one.
