goodrelations

Dear all:

Much more than any other type of rich meta-data on the Web, 
GoodRelations-related data is subject to change and updates, e.g.

    * new prices,
    * changes in availability, or
    * new features.

Search engines in the traditional Web crawl your page only once in a 
couple of weeks or so. Usually, the pagerank or other popularity metrics 
are used to decide on which pages to crawl more frequently than others.

Now, it is important that you help the search engines to decide on when 
to crawl your GoodRelations-based Web content again.

There exist three techniques that should be used in parallel. See the 
new Wiki page at

	http://www.ebusiness-unibw.org/wiki/UpdatingGoodRelationsData

for an overview.

Best
