Comments to “Bookmarking a Webpage” at

The definition of bookmarking used in the example says “*In the context of
the World Wide Web (http://en.wikipedia.org/wiki/World_Wide_Web) , a
bookmark is a locally stored Uniform Resource Identifier (
http://en.wikipedia.org/wiki/Uniform_Resource_Identifier)*”. However, it is
also possible to save bookmarks not locally but online, for instance in
delicious… maybe the Wikipedia page should be updated? Or maybe we should
extend this definition in our example in order to also include online
bookmarking systems.

oa:annotatedAt and oa:serializedAt do not extend from
w3prov:generatedAtTime but are inspired in, are not they? So the range
should be xsd:dateTime  rather than plain Literals. Right now, as quotes
are used for both, it is difficult to make clear the difference.

I am not sure whether it is right to use a Literal as range for foaf:mbox.
At http://xmlns.com/foaf/spec/#term_mbox, it says that Thing is the range…
should it be an Object rather than a Literal?

Do we want to encourage the use of dctypes:Text along with
cnt:ContextAsText? If the answer is yes, then we should add it to the
figure as well as a note reminding that it is a MAY

In the natural language explanations for the SPARQL queries, it should be
ex:person1 rather than ex:Person1

We have a type foaf:Person for ex:person1 but no type for ex:software1,
should not is be a foaf:Agent?

In general

Looking at this example I found a bit strange the relation oa:motivatedBy.
With oa:annotatedBy and oa:generateBy it is possible to respond questions
related to “who” while with oa:hasBody it is possible to respond questions
related to “what”. Would not it better to have oa:hasMotivation rather than

Should we include a legend at the beginning of the cookbook or maybe better
in the introduction explaining the different “boxes” that we use in
diagrams? Do the different colors mean something?  Also, should we use a
different line type in order to distinguish mandatory properties from
