Dear Evan:

I was just trying to investigate why the page

http://www.heppnetz.de/searchmonkey/product.html

does not appear in the Yahoo search results with SearchMonkey enhancements.

The markup is fine when checked with the Yahoo validator.

While doing so, I found that in the CACHED version, all RDFa attribute names are capitalized, e.g.

<span typeof="gr:UnitPriceSpecification">

was turned into

<SPAN TYPEOF="gr:UnitPriceSpecification">

Even worse, closing span / div elements are mostly omitted, and partly in lower caps, so that the opening and closing tags don't match.

This happens in particular for elements that have no visible content, e.g.

<span property="gr:validFrom" content="2009-07-20T00:00:00Z"></span>

turns ito

<SPAN PROPERTY="gr:validFrom" CONTENT="2009-07-20T00:00:00Z">

or

<SPAN PROPERTY="gr:validFrom" CONTENT="2009-07-20T00:00:00Z">
</span>

Consequently, PyRDFa cannot parse the cached document and when I submit the CACHED version to your validator, it does not find any markup (see screenshot).

===>  Can you please investigate this?

I think this is really a high priority issue, because you will create a lot of frustration among early adopters if their proper markup will not appear in Yahoo due to errors in the crawler or index.

Ideally, please submit

http://www.heppnetz.de/searchmonkey/product.html

to the crawler with high priority and check the results - if it works, please report.

For the community, it will likely be okay to wait a couple of weeks for inclusion or update. But it's really difficult to adopt the technology if it remains unclear whether problems at Yahoo's side are the source of observed problems while debugging requires such a delay between any iteration.

Best

Martin
