or anyone else for that matter) which allows anyone involved in those courses to communicate with their peers from any one of a dazzling array of online "places" with WikiEducator Notes (aka WEnotes). The entire system is free and open source software (FOSS). </p> <p>The magic glue is "tags" - most social media and online systems support "tagging" in one way or another. Tools like Twitter, <a href="https://github.com/tootsuite/mastodon" title="A FOSS alternative to Twitter, but distributed rather than centralised. Ruby-on-Rails and React.js are the underlying technology.">Mastodon</a>, and G+ support "hashtags" like "#OERu" as shorthand.

FOSS blogging engine used by 25% of websites.">WordPress</a>, and others), forums (like <a href="https://discourse.org" title="A next generation forum engine, FOSS, built on Ruby on Rails and Ember.js for the front end.">Discourse</a>), content annotation services (like <a href="https://web.hypothes.is/" title="FOSS website annotation system - review any web page, sentence by sentence. ">Hypothesis</a>), social bookmarking services (like <a href="http://semanticscuttle.sourceforge.net/" title="The software underlying our https://bookmarks.oeru.org service">Semantic Scuttle</a>), and instant messaging services (like <a href="https://rocket.chat" title="A FOSS private messaging system built on Meteor and React.JS, with MongoDB">Rocket.Chat</a>, <a href="https://about.riot.im/" title="A FOSS React.js-based private messaging client system built on top of the Matrix (matrix.org) messaging standard and the &quot;Synapse&quot; server (Python + Twisted).">Riot</a> + <a href="https://matrix.org/docs/projects/server/synapse.html" title="The Matrix server used by the Riot messaging client.

WEnotes is sensitive to those tags, and thanks to the modern trend towards services providing feeds, it can happily "harvest" relevant content from all over the web, in real time (or nearly, depending on the technology).</p> <h2>How WEnotes components fit together</h2> <p>WEnotes is a collection of a significant number of separate FOSS components. See the graphical diagram of WEnotes alongside this article for an overview of the WEnotes component architecture. To provide further explanation, WEnotes is made up of several functional components:</p> <ol><li>A set of feed harvesting scripts that are part of the <a href="https://bitbucket.org/wikieducator/wenotes-tools">WEnotes-tools project</a> (written in Javascript and Python, for those interested in that sort of detail, the former ideal for those sites producing JSON feeds and real time updates, the latter our choice for periodic scans - every 10 minutes by default at the moment - of RSS and ATOM feeds)</li> <li>A central <a href="http://couchdb.apache.org/">CouchDB</a> instance, which stores all posts harvested, along with metadata like their source, a unique ID (to ensure we don't re-harvest it) and some useful info to ensure we can push the messages to subscribers effectively.</li> <li>The WEnotes client for MediaWiki or WordPress, part of the <a href="https://bitbucket.org/wikieducator/wenotes">WEnotes project</a>, which provides a real-time feed of posts, either a full feed (for example <a href="https://wikieducator.org/WENotesCompleteFeed">this one</a>) or specific to a tag (for example a specific <a href="https://course.oeru.org/lida101/interactions/course-feed/">OERu Course</a>). The client also offers a posting interface, allowing logged in users to post new posts (up to 300 characters) automatically tagged in the relevant context. See two screenshots attached.</li> <li>A "publish-subscribe" or "Pub-Sub" service, <a href="https://bitbucket.org/wikieducator/wenotes-server">WEnotes-server project</a>, a Node.JS based <a href="https://faye.jcoglan.com/">Faye</a> implementation of the <a href="https://docs.cometd.org/current/reference/index.html#_bayeux">Bayeux protocol</a>. It uses <a href="https://en.wikipedia.org/wiki/WebSocket">websockets</a> to push out real-time updates to subscribed WEnotes clients.</li> <li> <p>The "couchwatch.js" script, also part of the WEnotes-tools project, watches the CouchDB and alerts Faye whenever a new post is received, which in turn pushes it out to subscribed WENote clients.</p> </li> </ol><h2>Whence WEnotes posts come</h2> <p>Here are three scenarios which outline the process by which a WEnote post is created.</p> <h3>Handy WEnotes post form</h3> <p>The most obvious way to create a WEnotes post is to go to a WEnote feed page - for <a href="https://course.oeru.org/lida101/interactions/course-feed/">instance</a> - and log into the system (assuming you have authentication credentials or can create some). If you're logged in, you should see a simple form as illustrated in the two attached screen shots. The system then knows who you are so that your post can be properly attributed, and it knows the "context" for the feed you're looking at (namely the associated tag). You can enter a message of up to 300 characters, and hit the "Post a WEnote" button, and this will send - direct from your browser - a suitably formatted post (a simple JSON object - example below) into the WEnotes CouchDB where it is then available for inclusion in relevant feed displays.</p> <h3>Personal blog post, appropriately tagged</h3> <p>If you register for our <a href="https://course.oeru.org" title="The main OERu course delivery platform for OERu itself and many partner institutions.">Course site</a>, or any course on that site, you have the option of adding a "Blog URL" - that's the web address of your blog (the address of <em>this </em>blog is <code>https://tech.oeru.org</code>, for instance). Because most widely used blogging platforms, like the open source <a href="https://wordpress.org">WordPress</a> platform (which is the most widely use web platform in the world, the basis for <a href="https://w3techs.com/blog/entry/wordpress-powers-25-percent-of-all-websites">25% of <em>all</em> websites</a>!! For the record, this website uses <a href="https://drupal.org">Drupal</a>, which is the 3rd biggest web platform, and is also open source), and proprietary cloud blogging platforms like Blogger and Medium, provide both "tagging" of posts and a built-in <a href="http://www.whatisrss.com/">RSS feed</a>. When you know what to look for, you'll start to see them all over the place (this blog has <a href="/blog/feed">one</a> - the logo is the little grey icon on the bottom left corner of <a href="/blog" title="The Tech Blog index page.">this page</a>).</p> <p>When you create a blog post on your registered blog and tag it with a course-specific tag (each course we run has one, it's usually the short code immediately after the main course website URL: <code>https://course.oeru.org/[course code here]/...</code>) the WEnotes feed harvesters will periodically visit your blog's RSS feed and look for new posts tagged with a course tag. If it finds one, it will create a new post in CouchDB with all the necessary info to provide an informative post in the WEnotes feed, proper author attribution (and an "avatar" picture of you where available!), and a way for interested readers to get to your original post.</p> <h3>Tagged/Hashtagged social media reference</h3> <p>Because the attention of many people is heavily focused on social media - dominated by "network effect" companies like Twitter and Facebook, for better or worse, but also by an array of more open and egalitarian services (which we, on principle, prefer, but recognise that they're far less well marketed due mostly to not taking anyone's money) - we also provide a variety of social media specific "feed harvesters".  Some of these periodically scan specific social media technologies for new relevant posts, others perpetually monitor their sources providing instant updates.</p> <p>If you</p> <ul><li><a href="https://mastodon.oeru.org" title="OERu's Instance of the open source Mastodon social media platform.">Toot</a> including a relevant hashtag (e.g. #oeru or #lida101 for the "Learning in a Digital Age 101" course),</li> <li>use <a href="https://hypothes.is">Hypothesis</a> to annotate a web page, tagging it appropriately (e.g. oeru or lida101),</li> <li>add a <a href="http://semanticscuttle.sourceforge.net/">Semantic Scuttle</a> "<a href="https://bookmarks.oeru.org" title="Our Semantic Scuttle instance.">Bookmark</a>" to a web reference of interest, tagging it appropriately,</li> <li>add a topic or reply on our <a href="https://community.oeru.org" title="Our Discourse forum for educators and OER developers">Community</a> or <a href="https://forums.oeru.org" title="The OERu's Discourse forum for learners">Forums</a> Discourse instances also suitably tagged, or</li> <li>create a <a href="https://moodle.org/" title="Market leading learning management system (it's also open source).">Moodle</a> post on a Moodle site running a suitable "student bot",</li> </ul><p>the WEnotes feed harvesters will find it and create a suitable post in the CouchDB.</p> <h2>How WEnotes feeds are made</h2> <p>Once you have a bunch of WEnotes posts stored in CouchDB, how do we create a feed? At present, we have "WEnotes client" scripts that run either on MediaWiki instances, like Wikieducator, or on WordPress sites, like our Course multisite, for which content is usually provisioned per-course using our "<a href="/oeru-mediawiki-wordpress-snapshot-toolchain">Snapshot</a>" toolchain. In both cases, the client is invoked via the inclusion of a "Widget" in the MediaWiki content that will either be viewed on the <a href="https://wikieducator.org/WENotesCompleteFeed" title="An example of the WENotes Widget, in this case a full feed, not restricted to one or more tags.">MediaWiki instance itself</a>, or on a target <a href="https://course.oeru.org/lida101/interactions/course-feed/" title="This is an example of the widget being transferred to a WordPress course subsite. Note the 'Content' link at the bottom of the page, which points to the Wikieducator page which contains the actual Widget.">WordPress course subsite</a>.</p> <p>After you log into the Wikieducator site, and create or find a page on which you want a feed, you "Edit source" and you can add both a <a href="https://wikieducator.org/Widget:WEnotesPost" title="The WENotes Post Widget how-to documentation.">WEnotes Post template</a> and <a href="https://wikieducator.org/Widget:WEnotes" title="The WENotes Feed Widget documentation">WEnotes Feed template</a> two simple one line recipes like this:</p> <p><code>{{#widget:WEnotesPost|tag=lida101}}<br /> {{#widget:WEnotes|tag=lida101|count=20}} </code></p> <p>This invocation will create a page showing a WEnotes Post Widget, where any submitted post will automatically be tagged by "lida101", and directly below that, a feed showing up to 20 posts from the CouchDB tagged with "lida101". Note, any <em>new</em> suitably tagged posts will pop into the feed in realtime as they're added to CouchDB thanks to couchwatch.js and Faye - invoking a WEnotes Feed Widget automatically subscribes you to realtime updates for that tag.</p> <p>You can also create a cross-tag feed using the magic <code>"_"</code> designator. WEnotes Posts require a tag (the default, if none is specified, is "wikieducator"):</p> <p><code>{{#widget:WEnotes|tag=_|count=20}} </code></p> <h2>WEnotes technical details</h2> <p>This is a tech-blog, so I'm not going to shy away from the technical details. Here're some useful bits and pieces for folks wanting to get a better understanding of this system. If you're scared of technical details, you can stop reading here.</p> <h3>WEnotes technology infrastructure</h3> <p>We implement the services making up the WEnotes stack using a set of three Docker containers as well as our main MediaWiki implementation, WikiEducator, and our main WordPress multisite implementation, the OERu Course multisite (we also maintain development instance of each of these). The Docker containers are managed with <a href="/docker-compose-better-way-deploy-rocketchat-wekan-and-mongodb">Docker Compose</a> and the roles are divided  We've created a separate <a href="https://github.com/oeru/wenotes-docker">code repository on GitHub </a>for our evolving WEnotes stack to facilitate others making use of some or all of it! The three containers currently being deployed do the following:</p> <ol><li>run CouchDB version 2.0 or later, as well as its "Fauxton" interactive web front-end.</li> <li>run the Faye Pub-Sub websocket destination for realtime feed updates, implemented as a Node.JS service running under <a href="http://pm2.keymetrics.io/">pm2</a>.</li> <li>run the Javascript (using pm2) and Python-based (using cron to run periodically) feed harvesters and the Javascript "couchwatch.js" script which alerts Faye to the addition of new posts.</li> </ol><p>Once configured (we're working on making that a straight forward "out-of-the-box" experience, although it's not quite there yet), the three containers can be deployed together with a single invocation of Docker Compose - at the moment, though, this system is quite dependent on a properly configured "options.json" file, the format of which is still in a state of flux.</p> <h3>WENotes JSON object</h3> <p>A WEnotes post is stored in our CouchDB as a JSON object (JSON = <a href="json.org" title="JSON is rapidly superseding XML as a way of storing and propogating machine-readable structured data. ">JavaScript Object Notation</a>). This is an example of a Post as it's stored in our CouchDB:</p> <p><blockcode>{<br />   "_id": "3e1c16eb1c99ae59899761a680006f4a",<br />   "_rev": "1-7462f14a0515d98b5985b9f4b8c39dd5",<br />   "media_attachments": [<br />     {<br />       "url": "<a href="https://mastodon.oeru.org/system/media_attachments/files/000/000/017/original/c3e85e56142c5c4d.png?1505016473">https://mastodon.oeru.org/system/media_attachments/files/000/000/017/or…</a>",<br />       "text_url": "<a href="https://mastodon.oeru.org/media/jvUoIpj6OAt-e5t-H8k">https://mastodon.oeru.org/media/jvUoIpj6OAt-e5t-H8k</a>",<br />       "preview_url": "<a href="https://mastodon.oeru.org/system/media_attachments/files/000/000/017/small/c3e85e56142c5c4d.png?1505016473">https://mastodon.oeru.org/system/media_attachments/files/000/000/017/sm…</a>",<br />       "meta": {<br />         "small": {<br />           "width": 400,<br />           "size": "400x321",<br />           "aspect": 1.2461059190031152,<br />           "height": 321<br />         },<br />         "original": {<br />           "width": 1148,<br />           "size": "1148x921",<br />           "aspect": 1.246471226927253,<br />           "height": 921<br />         }<br />       },<br />       "type": "image",<br />       "id": 17,<br />       "remote_url": ""<br />     }<br />   ],<br />   "truncated": true,<br />   "reblog": null,<br />   "id": 21,<br />   "in_reply_to_id": null,<br />   "content": "&lt;p&gt;Productive weekend fixing hashtags and instructions for &lt;a href=\"<a href="https://mastodon.oeru.org/tags/lida101">https://mastodon.oeru.org/tags/lida101</a>\" class=\"mention hashtag\" rel=\"tag\"&gt;#&lt;span&gt;LiDA101&lt;/span&gt;&lt;/a&gt; photo challenges .

Currently, the list is being updated manually, but it is <a href="http://wenotes.oeru.org/resources/feed-sources.json" title="WENotes Tag List">available as a web feed</a> in JSON format. We intend to provide both a simple editing interface for this list and to provide an API to automate adding new tags. Eventually, when we create a new course on our Course multisite, we expect to be able to automatically register the new course "tag" with the tag list.</p> <h2>Credits</h2> <p>The entire underlying mechanics and most of the cleverness of WikiEducator Notes are thanks to the ingenuity and hard work of <a href="https://wikieducator.org/User:JimTittsler">Jim Tittsler</a>, my predecessor as OER Foundation Technical Lead.</p> </div> </div> </div> <section class="field field-node--field-blog-comments field-name-field-blog-comments field-type-comment field-label-above comment-wrapper"> <a name="comments"></a> <div class="comment-form-wrapper"> <h2 class="comment-form__title">Add new comment</h2> <drupal-render-placeholder callback="comment.lazy_builders:renderForm" arguments="0=node&amp;1=16&amp;2=field_blog_comments&amp;3=comment" token="PxBEEjMNnN6bxJwA5uTvkIiXXSU76SK-WRBHv4dgcXc"></drupal-render-placeholder> </div> </section> Wed, 23 Aug 2017 21:21:04 +0000 dave 16 at http://tech.oeru.org
