Fwd: Atom and bidi

[Henry Story]

The Atom Syntax group is discussing a bidi proposal (see end). I am
not sure how much chance it has of getting through, and I don't
understand the issues that well yet ( I have a few other things to do
right now ), but I thought I should point out how I think it could
impact AtomOwl.

In a recent thread in this group entitled "Making Content into
Literals in AtomOWL", I was arguing for using literals more in the
AtomOwl ontology.

Ie. I am suggesting that we convert

<entry>
<title>Atom-Powered Robots Run Amok</title>
...
</entry>

into

[] a :Entry;
:title "Atom-Powered Robots Run Amok"^^:text ;
.

Literals in rdf don't have space for a bidi encoding. There is space
for language encoding
such as "hello"@en^^:text but none for bidi.

I suppose this is not really a problem as one could always encode
this in unicode when needed or for xml
fragments add it to a <div> in the content.

If it really were a problem, then that may constitute an argument for
using a content object.

[] :title [ a :Content;
:text "Atom-Powered Robots Run Amok";
:bidi :rtl; ] .
