Using schema.org/Product image on a non image element
seo,prestashop,product,schema.org,microdata
If you are using the itemprop attribute for an a element, the property value will be the URL specified in the href attribute, not the content of the a element. So in your example, the image property has the value link-to-product (which will be interpreted as URL): schema:Product → schema:image...
schema.org Microdata for headings in book
No, Book doesn’t offer properties for headings of chapters. You can only specify the title/name of the whole book (name, alternateName, alternativeHeadline). On a structural level, you could make statements about the webpage content, i.e., use WebPageElement and its name for every chapter. But this would have no relation to...
Sitelinks Search Box JSON-LD giving error on Google Structured Data Testing Tool
schema.org,google-rich-snippets,json-ld
I noticed that even the examples on the online documentation receive the same exact error you received. When I changed "@context": "http://schema.org" to "@context": "http://schema.org/true" the error disappeared. Hope this helps. <script type="application/ld+json"> { "@context": "http://schema.org/true", "@type": "WebSite", "url": "https://www.saatler.com/", "potentialAction": { "@type": "SearchAction", "target": "https://www.saatler.com/arama?ara={search_term_string}", "query-input":"required name=search_term_string" } }...
Applying RDFa to a list completed projects with location
For anyone curious, I ended up going with Creative Work: <article class="completed-work" vocab="http://schema.org/" typeof="CreativeWork"> <h2 property="name">The Empire State Building</h2> <ul> <li><strong>Location</strong> <span property="contentLocation">New York, New York</li> <li><strong>Completed</strong> <span property="dateCreated">2010</span></li> <li><strong>Architect</strong> <span...
JSON-LD Create Single Review for Person
json,schema.org,review,linked-data,json-ld
Apart from the comment and two comma errors this is valid JSON-LD. I wouldn't expect this to show up as a rich snippet though. The page you referenced lists the entitz types for which reviews are supported: "We support reviews and ratings for a wide range of schema.org types, including...
Can you use plain text for addresses in schema.org markup?
html,schema.org,structured-data
Yes, you may use text as value for address. While its expected value is another item (namely PostalAddress) instead of text, Schema.org does not require this (bold emphasis mine): While we would like all the markup we get to follow the schema, in practice, we expect a lot of data...
Schema.org, correct Attributes for a School Undergraduate Program
CollegeOrUniversity is for the organization, not for something that this organization does or has. EducationEvent seems to be appropriate. You could specify the CollegeOrUniversity as organizer of the EducationEvent. Apart from typicalAgeRange, EducationEvent doesn’t offer properties to denote the target audience of the event. So specifying that it’s for "Graduate...
Is it okay to use same schema.org markup twice on one page?
schema.org,microdata,rich-snippets,structured-data
Unless you use itemid, consumers can’t be sure that two (or more) items are (about) the same thing. So they would learn that your Product item has two AggregateRating items. Consumers might try to deduce that both items should be the same (e.g., by comparing url values), but you would...
Classifying chemical raw materials to introduce in Schema.org
As you said, these are products (i.e., they offer these, right?), so the Product type seems to be appropriate. MedicalEntity (or one of its sub-types) would only be appropriate for those products that are "related to health and the practice of medicine". If that’s the case, you could add it...
Schema.org's WebSite vs WebPage
WebSite represents a web site, WebPage represents a web page (like the difference between Blog and BlogPosting). The additional properties from WebPage (like breadcrumb and mainContentOfPage) wouldn’t necessarily make sense for WebSite. Google’s Sitelinks Search Box uses WebSite because the search usually applies to the whole site, not just a...
Why is the schema.org JSON-LD representation so small?
Because this isn't the definition of the vocabulary but just Schema.org's JSON-LD context i.e., a mapping from nice, short JSON terms to full URLs. See http://www.w3.org/TR/json-ld/#the-context for details. The reason why it doesn't map each property and class one by one is that it uses the @vocab shortcut which is...
what is the current opinion on using tags to hide individual instances of a recurring itemtype=“http://schema.org/Event”
You don’t have to duplicate the description, you can use the itemref attribute: <p itemprop="description" id="farm-market">…<!-- description for all events --></p> <div itemscope itemtype="http://schema.org/Event" itemref="farm-market"> <time itemprop="startDate">2015-01-20</time> </div> <div itemscope itemtype="http://schema.org/Event" itemref="farm-market"> <time itemprop="startDate">2015-02-04</time> </div> If you don’t want to show any content from the single events...
Is it good to use ItemPage (schema.org) to my courses?
If the page is about a single course, then yes, you may use ItemPage. As a general rule, always go with the most specific type. So if you have a WebPage, check its "More specific Types"; if one of the types applies to your case, select it; otherwise, keep WebPage....
Do I need to repeat all the categories on all sub-pages?
Schema.org doesn’t define any required properties, so everything is optional. But note that there is no concept of "website" in Microdata. The Microdata always gets parsed per document. So if a Microdata consumer parses your "Special Offer Weekend in New York" page, it will not get the telephone/address/etc. of the...
