Hi Martin, Thanks for your feedback on the first two cases. A few thoughts... Both Offer and PriceSpecification have the fields validFrom and validThrough. Is there a reason to allow it to be specified in both places? If so, what's the interpretation when the dates don't agree? We need to relate the VideoObject, the Thing (TV/Movie) and the offers. VideoObject has important information like geo restrictions, etc. We would like to maintain consistency with the predominant use case of non-premium content videos, so moving the restrict information into offer or product would be suboptimal. To link the three we could take the second Movie object in your example and change it to a VideoObject. It looks like your example adapts well since the essential properties are those of the Product type and not of the Movie type. The one issue not addressed by this model is how to distinguish the full content from trailers, clips, interviews, reviews, etc. These aren't typically products but if you have any insight I'd be glad to hear them. Here's what the anotations might loook like. <!-- Movie --> <div itemprop="about" itemscope itemtype="http://schema.org/Movie" itemid="http://www.imdb.com/title/tt0325980/"> <link itemprop="type" href="http://schema.org/ProductModel" /> <h1 itemprop="name">Pirates of the Carribean: On Stranger Tides (2011)</h1> <span itemprop="description">Jack Sparrow and Barbossa embark on a... </span> </div> <!-- Video --> <div itemprop="video" itemscope itemtype="http://schema.org/VideoObject"> <link itemprop="type" href="http://schema.org/SomeItems" /> <h2>Video: <span itemprop="name">Pirates of the Carribean: On Stranger Tides (2011)</span></h2> <meta itemprop="duration" content="T1M33S" /> <meta itemprop="thumbnailUrl" content="thumbnail.jpg" /> <meta itemprop="contentURL" content="http://www.example.com/video123.flv" /> <meta itemprop="embedURL" content=" http://www.example.com/videoplayer.swf?video=123" /> <meta itemprop="uploadDate" content="2011-07-05T08:00:00+08:00" /> <meta itemprop="expires" content="2012-01-30T19:00:00+08:00" /> <meta itemprop="height" content="400" /> <meta itemprop="width" content="400" /> <object ...> <param ...> <embed type="application/x-shockwave-flash" ...> </object> <span itemprop="description">Video description</span> </div> <link itemprop=”offer” href=”#buyoffer” /> <link itemprop=”offer” href=”#rentoffer” /> <link itemprop=”offer” href=”#subscribeoffer” /> <link itemprop=”offer” href=”#bundleoffer” /> <a itemprop "hasMakeAndModel" href="http://www.imdb.com/title/tt0325980/">More information on imdb.com</a> </div> <!-- Offers --> <div itemscope itemtype="http://schema.org/Offer" itemid=”#buyoffer”> <div itemprop="hasPriceSpecification" itemscope itemtype="http://schema.org/UnitPriceSpecification"> Buy for $<span itemprop="price">9.99</span> <meta itemprop="priceCurrency" content="USD"> <time itemprop="validThrough" datetime="2012-12-31T23:59:59Z"></time> </div> </div> <div itemscope itemtype="http://schema.org/Offer" itemid=”#rentoffer”> Rent for <span itemprop="price">$3.99</span> <span itemprop=”priceCurrency”>USD</span> <link itemprop="businessFunction" href=”http://schema.org/LeaseOut” /> </div> <div temscope itemtype="http://schema.org/Offer" itemid=”#subscribeoffer”> Subscribe for <span itemprop="price">$19.99</span> TBD... </div> <div itemscope itemtype="http://schema.org/Offer" itemid=”#bundleoffer”> Buy season 2 for <span itemprop="price">$39.99</span> TBD... </div> Best, Paul On Tue, Jun 5, 2012 at 1:24 AM, Martin Hepp <martin.hepp@ebusiness-unibw.org > wrote: > Dear Paul, > > for the first two cases (video purchase and rental), I would use the > GoodRelations extension as follows: > > = Buy Videos for Download = > > *On-line delivery / download > *You get permanent access to the video content > > First we describe the movie title as a product model: > > <xml> > <!-- The movie "model" --> > <div itemprop="about" itemscope itemtype="http://schema.org/Movie" > itemid="http://www.imdb.com/title/tt0325980/"> > <link itemprop="type" href="http://schema.org/ProductModel" /> > <h1 itemprop="name">Pirates of the Carribean: On Stranger Tides > (2011)</h1> > <span itemprop="description">Jack Sparrow and Barbossa embark on a quest > to > find the elusive fountain of youth, only to discover that Blackbeard and > his daughter are after it too.</span> > </div> > </xml> > > Then we describe the the actual movies that you can rent or purchase plus > the offer: > > <xml> > <!-- Some copies of that title --> > <div itemprop="about" itemscope itemtype="http://schema.org/Movie" > itemid="#video"> > <link itemprop="type" href="http://schema.org/SomeItems" /> > <h1 itemprop="name">Pirates of the Carribean: On Stranger Tides > (2011)</h1> > <span itemprop="description">Jack Sparrow and Barbossa embark on a quest > to > find the elusive fountain of youth, only to discover that Blackbeard and > his daughter are after it too.</span> > <a itemprop "hasMakeAndModel" href=" > http://www.imdb.com/title/tt0325980/">More information on imdb.com</a> > <!-- The offer to sell a copy of the video --> > <div itemprop="offers" itemscope itemtype="http://schema.org/Offer"> > <link itemprop="hasBusinessFunction" href=" > http://schema.org/Sell" /> > Price: <div itemprop="hasPriceSpecification" itemscope > itemtype="http://schema.org/UnitPriceSpecification">$ > <span itemprop="price">9.90</span> > <meta itemprop="priceCurrency" > content="USD"> > <time itemprop="validThrough" > datetime="2012-12-31T23:59:59Z"></time> > </div> > Delivery: <link itemprop="availableDeliveryMethods" > href="http://schema.org/DirectDownload" /> Download > </div> > </div> > </xml> > > Note 1: In the example, I used the more granular, new > http://schema.org/UnitPriceSpecification type.
