Reply to Web Annotations are Now a W3C Standard, Paving the Way for Decentralized Annotation Infrastructure

Web Annotations are Now a W3C Standard, Paving the Way for Decentralized Annotation Infrastructure by Sarah Gooding (WordPress Tavern)
Web annotations became a W3C standard last week but the world hardly noticed. For years, most conversations on the web have happened in the form of comments. Annotations are different in that they usually reference specific parts of a document and add context. They are often critical or explanatory in nature.

Be careful with this plugin on newer versions of WordPress >4.7 as the shortcode was throwing a fatal error on pages on which it appeared.

p.s.: First!

Kris Shaffer, the plugin’s author

Here’s his original post announcing the plugin. #

Web annotation seems to promote more critical thinking and collaboration but it’s doubtful that it would ever fully replace commenting systems.

But why not mix annotations and comments together the way some in the IndieWeb have done?! A few people are using the new W3C recommendation spec for Webmention along with fragmentions to send a version of comments-marginalia-annotations to sites that accept them and have the ability to display them!

A good example of this is Kartik Prabhu’s website which does this somewhat like Medium does. One can write their response to a sub-section of his post on their own website, and using webmention (yes, there’s a WordPress plugin for that) send him the response. It then shows up on his site as a quote bubble next to the appropriate section which can then be opened and viewed by future readers.


For those interested, Kartik has open sourced some of the code to help accomplish this.

While annotation systems have the ability to overlay one’s site, there’s certainly room for serious abuse as a result. (See an example at It would be nice if annotation systems were required to use something like webmentions (or even older trackback/pingbacks) to indicate that a site had been mentioned elsewhere, this way, even if the publisher wasn’t responsible for moderating the resulting comments, they could at least be aware of possible attacks on their work/site/page. #

Reply to Ben Hanowell about, Fragmentions, and Annotations

a tweet by Brash EquilibriumBrash Equilibrium (Twitter)
@ChrisAldrich is this the fragmentions plugin along with @hypothes_is or just the latter? Link to instructions por favor!!!!’ reply will get you most of the way, but I’ll add some additional thoughts below.

There are a couple of fragmentions plugins in the WordPress repository. I use and recommend WP Fragmention. Mostly it comes down to supporting a chunk of javascript that is the brainchild of Kevin Marks.

For, I use the plugin referenced in the tweet above, but I’ve also been using Aggregator by Kris Shaffer. I will note that the latter broke for me recently (possibly with the upgrade to WP 4.7, but I’ve filed a ticket and hopefully it’ll get sorted shortly). Shaffer’s plugin also makes using and posting with’ Chrome extension more useful and interesting to me, since I can own copies of my highlights/annotations on my own website.

I’m hoping that sometime soon that highlights and annotations on pages will also support sending webmentions so that when someone annotates one of my pages that I’ll receive a notification about it, almost as if it were a comment. If you’re interested in this sort of thing, Kartik Prabhu has a fantastic write up and some code on mixing marginalia and webmentions which I’m hoping to implement sometime soon myself.

If you need any help with any of the above, I (and surely others) are happy to help you via IndieWeb Chat.

Boffo Socko Now Supports Annotations

You can now highlight and annotate most of the pages here on Boffo Socko as well as other web pages.

I’d played around with many of them in the past, but a recent conversation with Matt Gross about News Genius and their issues in the last week reminded me about internet annotation platforms. Since some of what I write here is academic in nature, I thought I would add native Annotation support to the site.

hypothesisIf you haven’t heard about it before, you might find the ability to highlight and annotate web pages very useful. Hypothesis allows for public or private highlights and notes and it can be a very useful extension of one’s commonplace book.

At the moment, I’m not sure where it all fits into the IndieWeb infrastructure I’m building here, but, at least for the moment, I’d hope that those making public annotations and notes will also enter their commentary into the comments either here on the blog or by way of syndicated versions on Facebook or Twitter so that they’re archived here for posterity. (Keep in mind site-deaths are prevalent and even acknowledges in a video on their homepage that there have been many incarnations of web annotations that have come and gone in the life of the internet.) Perhaps one day there will be a federated and cross-linked version of highlights and annotations in the IndieWeb universe with webmentions included?!

Educators and researchers interested in using web annotation are encouraged to visit the wealth of information provided by providers like and  In particular, the blog has some great material and examples over the past year, and they have a special section for educators as well.

As it’s similar in functionality to highlighting on the web, I’ll remind users that we also still support Kevin Marks’s fragmentions as well.

If anyone is aware of people or groups working on the potential integration of the IndieWeb movement (webmentions) and web annotation/highlighting, please include them in the comments below–I’d really appreciate it.


Syndicated copies to: Now Supports Fragmentions!

A fragmention is an extension to URL syntax that links and cites a phrase within a document by using a URL fragment consisting of the phrase itself, including whitespace.

I’ve been meaning to do it for ages, but now supports fragmentions.

To take advantage of the functionality, append a # and the text you’d like to highlight on the particular page after the address of the particular web page. Add a + to indicate whitespaces if necessary, though typically including a single, unique keyword is typically sufficient to highlight the appropriate section.
