If it should work with existing parsers, if you have to embed it in

similar).
Is any other way of embedding RDF in HTML widely supported by RDF
parsers and tools?

Dear John,
I am not quite sure I understand your intention.
Am I supposed to embed a Microdata "island", which I then convert to RDF via
the JSON intermediate?
There is no official JSON format, so embedding JSON would still be kind of
a work around.
It would be perfect, if there was a more direct solution. Including the RDF
"island" as Turtle/N3 in the<script> part seems to be legit (Although a
little bit unconventional).
Is it possible to make an RDFa "island" somewhere? Where would I dump that?
Within the<head> or<body>? or parallel?
All the best,
Sebastian

How about following the approach described in the W3C "Microdata to
RDF: Transformation from HTML+Microdata to RDF" working draft
<http://www.w3.org/TR/2012/WD-microdata-rdf-20120112/>
There are a number of examples in that draft which seem compatible
with the problem statement, including embedded JSON (that can be
easily extracted and consumed as RDF)

Hello Sebastian,
You are making me nostalgic for a dispute I lost by shout-down with with
the
developers of RDFa :o)
Oops. Mr Erickson just beat me to the punch ... the critical point is
that
HTML has two bowls of tag soup (HEAD, BODY) related by proximity not by
authority. It's easy to assume that the HEAD is "global" to the BODY or
vice-versa. What you really want to do is cite a bibliographic reference
to
a set of RDF triples.
You can link to that file, or if you want to get fancy, embed an XML
Bibliographic Reference format like MODS from the LoC[1]. Embedding in
the
BODY is more polite, and reassuring if questions arise about download
size.

[1] Sorry, I have not looked at this in years so there will be some
syntax
issues. The idea is simple, MathML for people who do math, MODS for
people
who keep track of written stuff.

Subject: Re: best practice RDF in HTML
Sebastian, is the requirement that the RDF not be *integrated* with
the content of the page --- in other words, you just want to embed a
"dump" of some RDF?
Why not link to a RDF or TTL file?

Dear list,
What are the best practice to include a set of RDF triples in HTML.
*Please note*: I am not looking for the RDFa way to include triples. I
just
want to add a set of triples somewhere in an HTML document. They are not
supposed to show up like "Wikinomics", "Don Tapscott" in the following
example:
<div xmlns:dc="http://purl.org/dc/elements/1.1/";
about="http://www.example.com/books/wikinomics";>
<span property="dc:title">Wikinomics</span>
<span property="dc:creator">Don Tapscott</span>
<span property="dc:date">2006-10-01</span>
</div>
I don't want to use the strings in the HTML document as objects in the
triples. My use case is that I just have a large set of triples, e.g.
1000
that I want to include as a bulk somewhere and ship along with the html.
Which way is the best? Do the examples below work?
All the best,
Sebastian
