    In the video RDF when talking about N3 Notations at about the 3:04 mark, you have a bubble that says "This should be <"pref:likes"> but in the correction bubble there were no greater or less than tags, whereas in the example there were. So should it be "pref:likes" without the tags or <"pref:likes">  with the tags?

    Thanks,

    Caleb

    from http://www.w3.org/2000/10/swap/Primer

    @prefix dc: <http://purl.org/dc/elements/1.1/> .
    <> dc:title
    "Primer - Getting into the Semantic Web and RDF using N3".


    Note that when you use a prefix, you use a colon instead of a hash between dc and title, and you don't use the <angle brackets> around the whole thing. This is much quicker. This is how you will see and write almost all your predicates in N3. Once set up, a prefix can be used for the rest of the file.

     

    so back in case from video:

    pref:likes

    without <> or ""

    Thanks for asking!

    Thanks for answering my question. Web semantics is pretty interesting.

    Adding a new , very general question - hope this place suits it :

    As a newbie,

    I try to position rdf in relation to

     

     
    I am also interested in understanding various "Constraint standards" based on the context for which they can be used,
    and understand the interoperability of various vocabularies or constraint standards in topic maps, including certain rdf vocabularies.
     
    My attempt to understand this relates to a more specific field of interest related to "contract graphs", constraints used to support such approach, and usage of metadata produced through contracts made through social semantic graphs.
     
    I am looking into examples of contexts for which topic map constraints have been developped.  Any links welcomed.
