"Corporations are authors too, my friend"

Now finally aligning with what has long been supported by itself, Google now permits an Organization to be declared as the author of an Article. Previously the only permitted value was Person.

"Recommendations for the application of to aggregated Cultural Heritage metadata to increase relevance and visibility to search engines: the case of Europeana"

Some very interesting work from our friend +Richard Wallis and those he worked with at Europeana - check it out.

(It's with a smile that I'll note that I normally use a pull quote for these post titles, but that I ported the title there because you'd never be able to read it all in the link preview callout. With a smile because search engine visibility is referenced here, and Google truncates <title> tags at 512 px; this <title> is 1397px. :)

"We wanted to see what our library knowledge graph might look like and how it could generate new insights into how our people collaborate and how we present our skills and services to our users"

Don't let the seemingly library-centric title fool you: this piece by +Jason Clark and +Scott W. H. Young is a seriously good read for anyone interested in linked data, knowledge graphs and the application of structured data for SEO.

A number of new Google features are coming, including jobs and the indexing API

They all 404 right now, but in the rebuild of Google's reference documentation a big menu was added in the "Partner-only Features" page (

Will be interesting to see the details of each of these once they bring these pages live.

April changes to Google's structured data documentation

Numerous changes to Google's structured data and related pages today. Don't think any new data types have been propagated (appears to be more of an IA reorganization), but I haven't had time to review the changes in depth.

And nor, being about to board a plane, can I do so now. But I've provided my RSS feed if anyone wants to dig a little deeper on their own.

Importing lists from Wikidata to populate enumerations

Interesting proposal from +Ramanathan Guha and +Denny Vrandečić to employ Wikidata for enumerations.

There are many 'lists' or 'enumerations' (such as the list of countries,
languages, ...). Often, markup wants to refer to items from such lists. Since we have the corresponding types, pages can refer to them via descriptions (e.g., 'a country with the name xxx'). It would be useful to have canonical lists of urls for items on these lists to help with reconciliation, etc.

The proposal is to periodically (with every release) import particular lists from Wikidata into ''. So, ' <>', ' <>',
etc. Along with each item (such as, we should also import a set of attributes/relations from Wikidata so that we have a description of the node, which can help with recon using reference by description. It will also include a sameAs link to the corresponding Wikidata item.

Initial responses are generally quite positive (see the thread).

Also of note is the closing one-liner from Denny and Guha, which is anything but a throw-away: will also suggest the use of Wikidata as a common, canonical entity repository for targets of the sameAs relation.

Google officially unveils "Similar items" in image search

Following the introduction, in late 2016, of product information in image SERPs, Google has now extended the display of such item to display product information about similar items.

The “Similar items” feature is designed to help users find products they love in photos that inspire them on Google Image Search. Using machine vision technology, the Similar items feature identifies products in lifestyle images and displays matching products to the user.

The requirements for appearing as a "Similar item" are the same as those for generating product information in image search results: prescribed markup, including an image reference (

This was observed as a test recently, and to a certain extent Google's announcement is after the fact, as they refer to the feature as "recently launched". Here's a post by +Kara Eccleston of PMG describing the feature as spotted on 31 March 2017:

Yes, the timeline of Structured Data events has been updated. :)

Google introduces structured data markup guidelines for generating a "Fact check by" label in search results

Google has added a new data type in its documentation for structured data markup, "Fact check".

The new guidelines revolve around the type, with these required properties:
- datePublished
- url
- itemReviewed
- claimReviewed
- author
- reviewRating (interesting use of this - see the specifications)

itemReviewed and reviewRating require the use of CreativeWork and Rating, respectively, which have their own usage requirements.

The mechanism supports the posting of multiple fact checks for a single page, which generates a carousel of fact checks on mobile when more than one fact check rich result is displayed for a page.

Not clear whether this is only opt-in at this point, but the page has this message:

If your organization is interested in implementing, or seeing issues with, ClaimReview, submit your contact information here and our team may reach out to you. [link to form]

"Schema markup is one of those things that when I first approached it felt a bit like witchcraft"

The survey results are in from +Martha van Berkel and +Mark van Berkel of Schema App, and this was a comment from one of the 75 respondents.

Some interesting facts revealed by the survey; here's Martha's summary:

The results from the survey clearly state that Schema Markup is not reserved for the SEO elite, but is a language that is actively being adopted by SEO enthusiasts and experts alike to translate their content to be understood and perform in search engines. They share the desire to have more examples, and answers on best practices so they can figure out how to best represent their brands. While there are tools available on the markup that automate most of the process, while giving advanced users tons of options, many choose to do schema markup manually.
