Subject: [goodrelations] Modeling value dependencies and complex
	quantitative values with GoodRelations
Message-ID: <6422CC02-1227-4FEB-91E6-1574ED915B35@ebusiness-unibw.org>

Dear all:

When modeling product features, we sometimes encounter composite values, like
	? "1024 x 768 pixels resolution",
	? "8 litre of gasoline per 100 km/h", or
	? "a pressure of 101.325 kPa at 20 ?C" .

I just created a Wiki page that explains the usage of GoodRelations for such cases:

    http://wiki.goodrelations-vocabulary.org/Documentation/Structured_values_and_value_references

By the way, this pattern is heavily used in the Volkswagen Vehicle Ontology,

    http://purl.org/vvo/ns

which is a Volkswagen-specific extension of GoodRelations.

Best wishes

	Rich Snippets Faster

Dear all:

There is a Google feedback form that you can use to point Google to your shop if it uses GoodRelations markup.

This may speed-up the whitelisting process for Rich Snippets, i.e. you may get Rich Snippets for your products faster when you tell Google of your GoodRelations-empowered site.

Here is the URI:

    http://www.google.com/support/webmasters/bin/request.py?contact_type=rich_snippets_feedback

For the question "Does your site use hidden markup?", answer

* "yes"

if you are using a shop extension like Magento MSemantic. Other than Google indicates on the pages, this markup is perfectly accepted by Google unless you use it for manipulative purposes. As an explanation, you can post:

"Our site uses RDFa in the GoodRelations snippet-style, because this is the only feasible way of adding respective markup automatically via a shop extension module. We are using the <name of the module> module; our shop runs on <name of the shop software>."

For the question, "What markup format does your site use?", check 

* RDFa

In general, we see now pretty quick and broad acceptance of rich snippets for shops with GoodRelations markup.

Best wishes

Subject: [goodrelations] Google Rich Snippets for Prestashop: Free
	GoodRelations Module Released
Message-ID: <3664CCAE-BF78-4078-8C35-212EAA7513A2@ebusiness-unibw.org>

Dear all:

Makolab S.A. has just released a free and powerful extension module for the popular Prestashop e-commerce package that

1. will create Google Rich Snippets and
2. send rich relevance signals to search engines

by adding GoodRelations markup in RDFa syntax to the product item page templates.

The module is available here:

    http://addons.prestashop.com/de/seo/3866-goodrelations.html (you need to register to the Prestashop community system in order to see the download link)

There are installation instructions in English and French and the user interface is available in English, French, and German.

It should take only about 15 minutes to get this up and running, so this is by far the simplest way of adding GoodRelations support to a Prestashop.

A demo shop is at

   http://shop.goodrelations.pl/

Kudos to the Makolab team for implementing this!

Please spread the word to site-owners running Prestashop!

Best wishes

Martin Hepp

Subject: [goodrelations] How to get Google Rich Snippets in 5 days /
	GoodRelations markup
Message-ID: <7D9E8561-A0E5-4AB5-A2E1-F4554BCE5F60@ebusiness-unibw.org>

Dear all:

As many of you know, Google has been pretty slow in the past with turning on Rich Snippets (augmented search results) for shop pages that expose GoodRelations rich data markup.

Today, I found a shop that added GoodRelations ca. five days ago (!) and is already showing Rich Snippets in Google. See the illustration at

   http://yfrog.com/hsf45sp

for details.

The shop obviously uses the new free extension for Prestashop [1], developed by Makolab in Poland. Similar results should be obtainable using the other free extensions from [2], e.g. for Magento, Joomla/Virtuemart, OXID eShop, or for a Tradoria.de shop.

I personally think that one of the reasons for the much faster than usual activation of Rich Snippets for this shop is the fact that Prestashop has pretty good XML sitemap support on board, which allows Google to crawl the shop faster with less resources and thus helps updating the index faster. See

    http://asiavshop.de/sitemap.xml

The critical aspect of a good XML sitemap is that it uses the "lastmod" attribute properly for indicating which pages changed when:

<url>
<loc>http://asiavshop.de/sushi/92-sushi-reis-1kg-shinode-8005734100059.html</loc>
	<priority>0.7</priority>
	<lastmod>2011-12-15</lastmod>   <!-- this line is crucial -->
	<changefreq>weekly</changefreq>
</url>

Best wishes

Hello,

Can you tell me when the Real Estate spec will be available please. I am 
guessing something must exist as this page 
http://wiki.goodrelations-vocabulary.org/Cookbook/Real_estate says Yahoo 
have already implemented it.

Thanks

Ric

Hi all,

on
http://wiki.goodrelations-vocabulary.org/Quickstart

<div about="#offering" typeof="gr:Offering">
  <div rev="gr:offers" resource="http://www.hepps-bagels.com/#company"></div>
  <div property="gr:name"
       content="Canon Rebel T2i (EOS 550D) $899" xml:lang="en"></div>
...

code links the offer to the company.

How can i do it with microdata syntax?
i could not imagine usage of itemprop instead of rev

Thanks
