7.4.1 Scoping of Prefix Mappings

CURIE prefix mappings are defined on the current element and its descendants.

CURIE prefix mappings are defined on the current element and are valid for all its decendants, except another CURIE prefix mapping in a decendant element overrides it.

I was wondering, if it could be little more explanatory.

7.5, rule 11, third li.

Exclusive XML Canonicalization Version [XML-EXC-C14N]

Exclusive XML Canonicalization Version 1.0 [XML-EXC-C14N]

add 1.0

7.5, rule 13

not with blue background

.

Add ' div class="explanation" ' around the explanation after the colon?

7.6.2, second example

Three descriptions in the example.

Capital Letter and full stop.

The context descriptions vary from small letter at the beginning without '.' to capital letter and '.'. Keep it consistent.

8.1.1.3

... which means that the processor only requires one attribute, the value of the type.

... which means that the processor only requires the value of the type.

The word attribute is used in combination with element, attribute, value in HTML. Attribute in HTML sense would be @typeof, but here it has just some general meaning and points to the value of @typeof, so just skip the word attribute to avoid confusion. Otherwise, if you want to point that out like before, say: ... the processor requires only one more thingy, ... .

8.1.1.3 Typing resources with @typeof, after example 2

but the element is used only to define possible 'subject' resources via, e.g., @resource

.

Do you mean, 'define only possible subject resources for @typeof'? Because @resource should provide an object. I also don't understand the only, a resource should be there to give an object to a subject, or do you find @resource without an associated subject?

8.1.1.3 Typing resources with @typeof, after example 4

kontext

subject

.

8.3, last paragraph

A IRI resource object can be set using one of @rel or @rev to express a predicate.

An IRI resource object is used, if either @rel or @ref express/set a/the predicate, an explicit object resource can be set with/by one of the following attributes ... .

In the original constellation, it sounds a bit like @rel or @rev would set the value for the object.
One more thing: 'the @property ... to define an IRI resource' is not really clear in its statement.
Please check the paragraph above also: ... 'an' element, if @property 'expresses/is used to express' a predicate.

8.3.1

(and no resource attribute is present).

and no resource attribute is present

Remove the parantheses, sounds like an important condition.

8.4, example 4

<a> ... </span>

<a> ... </a>

It might be a because there is an href inside.

9. RDFa Initial Context

.

.

In the first paragraph, approved host languages are XML+RDFa and XHTML+RDFa. You might want to add HTML+RDFa by the time of publication or if not, a hint, that it is upcoming.

10.1

.

.

Im am a bit confused with the first paragraph. The section is said to be non normative, but the first paragraph is in dfn tags (what makes it appear in bold letters). The text sounds normative, but the proper normative version seems to be in 10.2. Might be better to remove the dfn tag.

B, first paragraph

.

.

An ordered list with three list items might be easier to read.

Status of the document

.

.

If you would ask me, I would say to remove all the changes from the status section and just refer to the section Changes. It is almost the same, and you have to read most things twice with just a little more info in Changes.

3.2, first note

.

.

Maybe a good idea to throw out the note in the next revision or adjust it.

7.4.4, after last example

No explanation why it is the same triple.

The first link uses the default prefix as described in section 6: Curie Syntax Definition, the second link uses the prefix xhv: which we defined for all examples in section 2: Syntax Overview.

The examples are for people to understand better or faster, this would help people, who read it first time or start somewhere in the middle.

4.1 and 7.6.1

1. The output graph and the processor graph are separate graphs and must not be stored in the same graph by the RDFa Processor.
2. For whole-graph RDFa Processors, the software must allow the developer to specify if they would like to retrieve the output graph, the processor graph, or both graphs as a single, combined graph from the RDFa Processor.

.

This sounded contradicting to me first. It is not, because once it is what the processor stores (this has to be two graphs) and the other thing is the output, where the graphs can be combined. These two statements are in two far away sections, so for the reader to get it right from the beginning, it would be nice to add something to the first sentence in 4.1 like: They might be joined in the output of the processor like described in section 7.6.1. .
Just an idea.

9. RDFa Initial Contexts, 2. and 3.

2. For every subject with a pair of predicates that have the values rdfa:prefix and rdfa:uri
3. ...

For every subject with a pair of the predicates rdfa:prefix and rdfa:uri ...
3. ...

The 'values of the predicates' are the object literals for the prefix and IRI. Here value is used in a different meaning.

several occurances

'hanging rel'

hanging @rel

9. last note

.

.

Looking at the last note now as a list, it looks quite like mandatory stuff, that should not be in an informative section like a note.

I have a remark about the usage of words.
There are many terms, that are defined for RDF(a), subject, object, property, value and so on. If these terms are used one time in the defined way as part of a triple, e.g., and in another place, e.g., object ist just used in a general way, it leads to confusion.
So these defined terms should be only used in the defined way, and find some other general words for what you want to say. Sometimes that might be difficult.
But instead of saying, there is an object in my rearview mirror, you just have to say, there is a car in the rearview mirror. (So nobody will ask you, if the car is a literal or an IRI.)
I hope you understand my weird example. :-)
