Hello,

The approach I have been taking to write the RDFa parser in EasyRdf, is to
work through each of the test cases and implement the parts that cause the
most tests to pass (according to the specification). Generally I worked
through the easiest to fix tests first.

I thought you might be interested to know what the final 6 tests that I need
to fix are.


0084: I think I need to implement 'skip element' in order to get this test
to pass. I am amazed that no other tests require this functionality.

0176: this is passing within my own test harness but not on rdfa.info. Need
to work out why.

0183: not sure how I am going to get this test to pass. PHP makes it tricky
to get hold of the @xmlns attribute, so I have been getting PHP's XML parser
top resolve namespaces, when I need to look them up. Mixing this with my own
@prefix table makes it difficult to pass this test.

0224: I think this is the only test for @inlist and incomplete triples.
Implementing inlist has been one of the largest amounts of work. Mainly
because to works very differently to the rest of the parser. PHP passes
arrays by value, by default - which was working great for passing contexts
down the tree. But I had to rework this when it came to implementing inlist
because of having to pass values back up to the calling function.

0303: Gregg tells me that this and 0312 is an HTML5 specific test and isn't
in a specification yet. I will probably just copy the code from his ruby
gem.

0312: Interesting this is actually passing for me on rdfa.info/test-suite -
I think the SPARQL query might need to be checked. The turtle output is
different to the reference implementation.


Note that I don't have a local SPARQL engine in EasyRdf - so internally I
have been testing against the Turtle output of the Reference Implementation
(RDFa.rb).

ps. persona.org keeps on going down - making it hard to run the test suite.
