How do you use link text as value in schema.org value?
html,metadata,schema.org,microdata
Microdata does not provide a way to denote that an itemprop on an a element should not produce a URL as value. You have to add another element that is one of the elements that produces string values in Microdata (tl;dr: not time and not one of the elements that...
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...
Why is my schema.org rating markup for a place not being shown by Google?
schema.org,google-webmaster-tools,microdata
Google will not typically display an aggregate rating rich snippet for a "Place" itemtype. They do show it, though, for more specific place types, such as for restaurants and other local business types. So you might need to get more specific with your markup. On a different note, hiding marked...
Schema.org setup for multiple events on one page
schema.org,microdata,google-rich-snippets
Your usage of Microdata and the Schema.org vocabulary is valid. Every conforming parser will understand this. See for example http://linter.structured-data.org/, which shows snippets that could result from markup. However, actual search engine providers decide for themselves if, when or how to use your annotations, for example for enhancing search results....
Which Schema.org property should I use for related articles, quizzes, stories? [closed]
html5,semantic-markup,schema.org,microdata
Your example misses the ItemList type. You could add it to the aside element, e.g.: <aside itemscope itemtype="http://schema.org/ItemList"> <article itemprop="itemListElement" itemscope itemtype="http://schema.org/Article"> </article> <article itemprop="itemListElement" itemscope itemtype="http://schema.org/Article"> </article> </aside> Using the article element for each related story seems to be appropriate, especially if you provide content like a description/teaser, the...
Where to add Rich snippet - Organization schema for a general page
schema.org,google-rich-snippets
It's not necessary to put it on every page, but you should definitely insert it into pages such as the About page and Contact page, and you could also insert it into the homepage if there is an appropriate place for you to do so. You will just want to...
Write Microdata just with and
If the value is a URI, use link. Otherwise, use meta. So <span itemprop="ratingValue">4.6</span> becomes <meta itemprop="ratingValue" content="4.6" /> etc. If it’s just about having no visible content, you could keep using the parent div elements, e.g.: <div itemscope> <!-- you can/should give it an itemtype --> <div itemprop="aggregateRating" itemscope...
Can schema.org's email property use the href value?
html,email,schema.org,microdata
Schema.org’s email property expects Text as value. It’s odd. In my opinion it should take URL instead, or at least allow boths ways ("Text or URL", as it’s the case with the menu property, too). I can only guess that they chose Text because some publishers don’t want to specify...
Using an itemprop from one itemtype in another itemtype
Don’t use url. As you rightly point out, the url property is for the URL of the current item (i.e., the product), and not for URLs of related items. While the definition of the relatedLink property seems to be appropriate for your case, this property can only be used for...
Define extra properties for an existing class in RDFS?
semantic-web,ontology,schema.org,rdfs
Should I make my schema venue as a subclass of https://schema.org/Place and add new properties? If you're declaring a describing a class Venue, it makes sense to make it a subclass of some other Place class that someone else has declared, if you want to achieve some measure of...
How does schema.org usage fit into Linked Data principles?
rdf,schema.org,rdfa,rdfs,linked-data
From http://schema.org/docs/datamodel.html: The canonical machine representation of schema.org is in RDFa: schema_org_rdfa.html (See my answer on Webmasters SE for other representation.) This HTML+RDFa version uses the RDFS vocabulary. It’s as good as any other RDF serialization. If you don’t like RDFa, you could of course use your favorite converter to...
How to do a new extension with Schema.org + Microdata?
You may still use Schema.org’s "slash-based" extension mechanism. It’s "outdated", but not invalid. But it’s not (and never was) a good idea to use this mechanism if you want other consumers to understand or make special use of your extensions. In some cases you could use Schema.org’s Role type, which...
How can I add RDFa to my Google Site?
html,semantic-web,google-sites,schema.org,rdfa
Google Sites seems to remove some attributes (including those needed for RDFa and Microdata) when entering the markup in the HTML mode. Workaround: Insert → HTML Box This creates a box which seems to allow full HTML (and also CSS/JavaScript)....
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 there any way to get schema.org RDF in slices?
No, there is not. Ontology modularization is a non-trivial task. In a nutshell, it is easy only if the creator of the ontology implements it at design time. The reason is that there can be complex dependencies between the axioms for the various conceptual elements. I designed www.productontology.org specifically in...
How to specify tax in Gmail Schema.org markup?
The vocabulary Schema.org provides three sub-types for the PriceSpecification type: DeliveryChargeSpecification PaymentChargeSpecification UnitPriceSpecification Unless one of these applies in your case, you should use the parent type, PriceSpecification. (If it’s about a price that includes VAT, you can use the corresponding type and its valueAddedTaxIncluded property, which Google seems to...
How to model directories and files using schema.org types with JSON-LD syntax?
You might wanna consider the Nepomuk File Ontology (NFO) instead.
“Error: Incomplete microdata with schema.org” for Product
prestashop,schema.org,microdata,prestashop-1.6,google-rich-snippets
Your usage of Microdata and Schema.org is not wrong. The Google Structured Data Testing Tool is just "complaining" that you did not specify all properties Google Search needs for displaying one of their Rich Snippets. It seems that the culprit is the last Offer: <span itemprop="offers" itemscope="" itemtype="http://schema.org/Offer"> <link itemprop="availability"...
What Schema.org properties for video search results?
You could use the SearchResultsPage type for the webpage, the ItemList type for the result list, and the VideoObject type for each result. To relate the ItemList to the SearchResultsPage, you could use the mainEntity property, and to relate the VideoObject items to the ItemList, the itemListElement property. In RDFa,...
CSE does not pick up url from href attribute in a Element when using Microdata
javascript,schema.org,microdata
Ok finally after a lot of digging, I have the answer. The root cause is as follows: The Google CSE(Custom Search Engine) is not consuming the microdata property value as the href attribute of the "a" HTML element. It is consuming the child text content on the "a" HTML element....

“availability” not showing in Google Rich Snippet
html5,seo,schema.org,microdata,google-rich-snippets
I don’t know if this is the reason why Google Search does not pick it up, but your markup is not valid. The li element can’t have a href attribute. So instead of this <li itemprop="availability" href="http://schema.org/InStock">Op voorraad</li> you should use, for example, this <li><link itemprop="availability" href="http://schema.org/InStock"/>Op voorraad</li> Also note...
Schema.org is not validating: “it appears to include multiple reviews of an item, but no aggregate review information”
schema.org,rich-snippets,google-rich-snippets
I don’t know why Google’s old SDTT reports this, but their new SDTT doesn’t: Apart from the author property that Google would like to see for the Review items, no relevant errors or warnings are reported....
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...
How to implement schema.org on https pages
tl;dr: Use http URIs. In this answer on Webmasters SE I explained why you should favor http over https Schema.org URIs: The http URIs seem to be canonical, as the actual definition of the Schema.org vocabulary only defines http, not https. In addition: all examples (even on HTTPS) use the...
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....
How can I include an articleBody that is outside of the Article's itemscope?
It appears that I was on the right track. The problem I had was that I attempted to declare itemref multiple times, each time for another id. According to W3C, itemref actually expects a space-separated list of id values. Here is the working example: <html> <body> <div itemref="content company" id="articleHeader"...
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...
When is it worth creating an XML Schema (XSD)?
You tagged your question with seo and html, but those are not reasons to define an XML Schema (XSD). You mention "Creative Work", but that concept is also immaterial to XSDs and their benefits. The Value of Defining an XSD There is value in defining an XSD in so far...
How to cite a blog post using HTML microdata and schema.org?
html,schema.org,microdata,citations
If you’d ask me which markup to use for a list of links to blog posts (OP’s context), without seeing your example, I’d go with something like this: <body itemscope itemtype="http://schema.org/WebPage"> <ul> <li> <cite itemprop="citation" itemscope itemtype="http://schema.org/BlogPosting"> <a href="…" itemprop="url" rel="external"><span itemprop="name headline">Hello World</span></a>, authored by <span itemprop="author" itemscope itemtype="http://schema.org/Person"><a...
Schema.org Organization: url, logo in one place and social links in another
Microdata’s itemref attribute can be a solution. But this only works if you have no other parent itemtype open (e.g., on the body). <div itemscope itemtype="http://schema.org/Organization" itemref="social-links"> <a itemprop="url" href="/"> <img itemprop="logo" alt="sitename" src="logo.png"> </a> </div> <ul id="social-links"> <li><a itemprop="sameAs" href="https://www.facebook.com/site"></a></li> <li><a itemprop="sameAs"...
Difference between MusicGroup and Person in schema.org
schema.org,rich-snippets,google-rich-snippets
As the Schema.org documentation says, a "MusicGroup" can refer to a solo musician, and should be used. It has the benefit that you can have "album" and "track" properties that allow you to define the solo musician's recorded works (which are not present in "Person"). Probably, but that's entirely...
Can I have multiple images marked up in a schema.org ImageObject?
If you’d use one ImageObject with multiple contentUrl properties, it would mean that you have one image with several URLs. If you have several images, use an own ImageObject item for each....
Microdata/Schema.org/SEO: How to properly set a ContactPoint
(While Google’s Testing Tool reports this as an error, it’s not an actual error. It should be a warning instead. Your code is valid Microdata and you are correctly using the Schema.org vocabulary.) You have two top-level items (a Person and a ContactPoint), i.e., they are not related in any...
How to nest Microdata (using Schema.org) in a valid way?
I think that rather that deem it a Google glitch, it's a reflection of the paucity of development. In other words it seems probable that this is a highly immature protocol, rather than a bugged one. In my application first names and surnames are presented in a table, which makes...
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...
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...
Schema.org mandatory fields and the time needed until Google shows changes
seo,schema.org,google-rich-snippets
There are no mandatory properties/types in Schema.org. However, consumers of the data, like Google Search, might have rules under which conditions they will make something with your data (e.g., they are looking for specific properties). So you’d have to check their documentation. For Google Search, their Rich Snippets are documented...
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...
Google sitelinks search box snippet doesn't work

Content-Type for Email Markup Actions

You have to include it in the email’s HTML (text/html). Google (i.e., Gmail and Inbox by Gmail) supports JSON-LD and Microdata: The JSON-LD will be included in a script element (used as data block). The Microdata attributes (like itemscope and itemprop) will be added directly to the (existing) HTML elements....
Structured data not being picked up on telephone number
html5,schema.org,microdata,google-rich-snippets,structured-data
Schema.org’s telephone property expects Text as value, not a URL. (There’s a feature request to change this.) So you could use something like this: <div itemscope itemtype="http://schema.org/Organization"> <p>Call Us: <a href="tel:07749918143"><span itemprop="telephone">07749 918 143</span></a></p> </div> ...
Why use Schema.org microdata to mark up web page elements?
Schema.org is not restricted to HTML5. Schema.org is a vocabulary which can be used with various syntaxes (like JSON-LD, Microdata, RDFa, Turtle, …), stand-alone or in various host languages (like HTML 4.01, XHTML 1.0/1.1, (X)HTML5, XML, SVG, …). So having other ways to specify that something is (or: is about;...
How to setup “application/ld+json” schema.org meta data in rails 4 app
ruby,ruby-on-rails-4,metadata,schema.org,json-ld
There is a JSON-LD gem (http://rubygems.org/gems/json-ld), but it might not be specifically what you're looking for. Note that the point of JSON-LD is that it's just JSON, in this case using the schema.org context to interpret the values. Assuming that your data is in ActiveRecord models, you'll need a way...

html,seo,schema.org,google-rich-snippets
Whether you use different paths (…/en/ + …/de/), different subdomains (en.example.com + de.example.com) or different domains (example.com + example.net), you have different (albeit translated) websites. So use a separate WebSite item for each of your sites. Example (using RDFa) On http://example.com/en/, you could specify: <head typeof="schema:WebSite"> <title property="schema:name">Example</title> <link property="schema:url"...

Does Google not support rich snippets for reviews of the schema.org type VideoGame?

Google does not display a Review Rich Snippet for all of the Schema.org types, but they don’t explicitly list which types are supported (emphasis mine): We support reviews and ratings for a wide range of schema.org types, including businesses, products, and different creative works such as books or movies.

schema.org microdata: Do as schema.org says, or as Google says?
schema.org,microdata,google-rich-snippets
I would use schema.org. The high prevelance of the year "2011" on that Google page makes me have a feeling that it is older content that hasn't been updated or removed. I used schema.org structured data elements on a site I maintain, and all of those elements show up correctly...
When to use the subclass in RDFS?
The semantic web / linked data lives of the re-use of existing vocabularies, so if you only need a sub-set of existing vocabularies, it's best to not re-invent any new schema, but just to use parts from existing ones. Your data will then even be useful without any reasoning. Also,...
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...
nested microdata properties with 3 levels
You missed the name for the product and didn't declare an item scope for review.

Product size: width, height and depth
The width/depth/height properties expect Distance or QuantitativeValue as value. So if you want to use Distance, it might look like: <span itemprop="width" itemscope itemtype="http://schema.org/Distance"> 60 <span>cm</span> </span> If you want to use QuantitativeValue: <span itemprop="width" itemscope itemtype="http://schema.org/QuantitativeValue"> <span itemprop="value">60</span> <span>cm</span> <meta itemprop="unitCode" content="CMT" /> </span> Instead of specifying the...
