In our course E-Learning 3.0 (#el30) facilitator Stephen Downes asked us to create an identity graph. We should not use a node “me”, “myself” or similar. I made a mind map using Mindmaster, but I dislike the fact that the format seems to impose a central node. I put buddhism/humanism central, since that are core values and practices which permeate my life. Part of it, of course, is aspirational. Actually it would be nice to see the nodes moving, changing positions all the time. Stephen also asks some questions about the graph:

  • What is the basis for the links in your graph: are they conceptual, physical, causal, historical, aspirational? Answer: Well, all that.
  • Is your graph unique to you? What would make it unique? What would guarantee uniqueness? Answer: The combination of interests, passions maybe rather specific, but is it unique? Why should it be unique? And if there is such a thing as ‘typically me’, I guess it somehow eludes whatever description or graph.
  • How (if at all) could your graph be physically instantiated? Is there a way for you to share your graph? To link and/or intermingle your graph with other graphs? Answer: The graph is shared here, Mindmeister gives tools to share and mix. I could have embedded the graph, but I avoid that for security reasons.
  • What’s the ‘source of truth’ for your graph? Answer: Introspection, which is always dubious.

The task for this week in the course E-learning 3.0:

Create a model graph of some aspect of the E-Learning 3.0 course (it doesn’t have to be an actual graph, only a representation of what an actual graph might look like. We’ve already seen, eg., graphs on the relations between people in the course. Could there be other types of graphs?
In your model, consider how the states of the entities in that graph might vary. Consider not only how nodes might vary (eg., a person might have a different height over time) but also how the edges might vary (eg., a person might have a different strength of relation (calculated how?) with another person over time).
In your model, consider how knowledge about the changes in states in the graph might be used.

I just wonder whether the nodes of vertices should be people and the relations or edges should be between people (or their blogs). I’m more inclined to have ideas or topics as nodes and draw the relations between ideas. Such a graph would be very similar to a concept map.

How would the states of the entities in the graph or concept mqp vary? One could use a tool such as Mindmeister to have a timeline of versions. The first map, corresponding to the start of the course, probably would probably depict a limited number of rather general ideas, but as the course grows and the map gets more complex, the ideas would become more differentiated and the strength of the connections could also very.

Other tools such as TheBrain allow you to build giant databases in the form of mind maps or even one big all-encompassing map (I won’t elaborate here on the differences between mind maps and concept maps). It’s possible to have the system show the different entities in a random way, offering you the different perspectives on the map in quick succession.

Not sure whether the concept maps count as “graphs” but I think they do and I’d love to try this out.

Course participant Matthias does something similar on this blog, using Cmap. (He made his own tool http://condensr.de/ as Jenny says in the comments on this post).

Facilitator Stephen Downes of the course E-learning 3.0 (#el30) explains Graphs in this video. In his own words:

The graph is the conceptual basis for web3 networks. A graph is a distributed representation of a state of affairs created by our interactions with each other. The graph is at once the outcome of these interactions and the source of truth about those states of affairs. The graph, properly constructed, is not merely a knowledge repository, but a perceptual system that draws on the individual experiences and contributions of each node. This informs not only what we learn, but how we learn.

Graph vs. storytelling

What interested me particularly is the idea that stuff like this website can be represented as a graph, which is fundamentally different from a representation as a linear narrative. Graphs enable a view from a variety of perspectives. In education we are drawn towards the narrative, the causal explanation, the single actor. There is a critique of this in the book How history gets things wrong by Alex Rosenberg. Professor Rosenberg (Duke University) demonstrates how our addiction to narratives gets in the way of understanding history. Graphs can be a corrective on this.

The question is whether narratives should by definition be linear. Cannot we tell stories with different paths depending on choices made by the people formerly known as the audience – making them active participants?

A demonstration of graphs can be found in this post by Laura Ritchie. It demonstrates that when we demonstrate our learning with a graph we change our perception of what it is we are learning and how we are learning. It changes our understanding of where the knowledge comes from. The essence is that everything depends on something else.

In GitHub you have cloning, versioning, merging, forking which are manipulations in a graph which lead to something new. Machine learning builds on the characteristics of graphs. Aggregating, remixing, repurposing are skills which define the new way to learn.

A graph or network is not just a place to store and manipulate data, it’s a perceptual system. Thinking and perceiving are one and the same state, so Stephen argues.

In the course E-learning 3.0 our facilitator Stephen Downes had an interview with Ben Werdmuller who co-founded Elgg and Known, worked on Medium and Latakoo, and invested in innovative media startups to support a stronger democracy at Matter. These ventures are very related to all things decentralized web, the movement away from the big silos such as Facebook, enabling internet users to own and manage their own data. But what are all these projects about? A brief overview:

Elgg is an award-winning open source social networking engine that provides a framework on which to build all kinds of social environments, Known allows any number of users to post to a shared site with blog posts, status updates, photographs, and more, Medium is a blogging platform, Latakoo moves big files around (think video) and Matter Ventures is a media accelerator.

While Matter is regrouping right now and Werdmuller is no longer involved there, he is working with yet another open source start-up, Unlock. That project wants to enable people to earn money on the web without middlemen. Unlock is a protocol which enables creators to monetize their content with a few lines of code in a fully decentralized way, so it promises. It’s blockchain but beyond the virtual currency speculation.

Graphs

In our course E-learning 3.0 (#el30) Stephen Downes discussed the graph-concept: “This concept will be familiar to those who have studied connectivism, as the idea of connectivism is that knowledge consists of the relations between nodes in a network – in other words, that knowledge is a graph (and not, say, a sequence of facts and instructions).” The interview is part of the graph-module of the course.

The blockchain fits into this notion of “graph”, yet there qre some wicked concrete problems involved: privacy, payments for illegal goods and services. The decentralized web in itself (which is broader than “the blockchain”) can also provide a safe haven for communities spreading hate and fake information, Werdmuller himself published a post about the highly controversial Gab-platform. It’s not very clear to me how to solve these issues which are already very challenging for big centralized companies such as Facebook and Twitter and which seem to be even more difficult on a decentralized web with lots of completely independent operators with often hidden identities.

Metadata are very important and enable authorities and big corporates to learn a lot about web users, while the common user herself does not have the means for these analyses. The rich and powerful can protect information while the rest of us basically are condemned to use open platforms or to allow companies to use our personal data.

Access

The decentralized web in itself right now is also open, but projects such as Unlock are not only important for facilitating the monetization of web content, but can also enable users to regulate access to information. The web right now has no access control layer, in the same way that is does not have an identity or payments layer. Just as there are now projects to provide a control layer, there are possibilities for an identity layer as major browsers launch cryptocurrency-wallets but all this seems to be very early phase.

IndieWeb is the idea that one should be able to share, discuss and publish from your own website or even domain name, in a way that is not controlled by any single company. Why is it bad that Facebook, Twitter and LinkedIn control these activities? There is a good side, the fact that these companies get better in fighting hate speech. But because Facebook for instance depends on selling ads, they have a strict identity policy which requires users to publish using their official name. That name policy is bad for vulnerable communities and has a chilling effect on discussions and open speech, so Werdmuller explains.

Your own site

But how realistic is it to expect everyone to run a website? Many hosting companies are doing a lousy job in terms of security and of user friendly interfaces – the widely-used installation technology cPanel looks like ancient technology from the nineties. There is a new generation of technology such as the Helm Personal Email Server which could expand into general hosting. Werdmuller also hopes a hosting company will conquer the market with easy to use 21st century technology for normal people. Prices now are still too high. Internet Service Providers want the ordinary consumer to download stuff, but if people want to upload and have their own servers they’ll push to more expensive business solutions. So there is still a very real broadband issue, even in cities such as San Francisco.

Werdmuller explained the more technical basics of the IndieWeb such as webmentions and classes which add semantic meaning to html-tags enabling users to communicate on other websites without leaving their own site. I wrote about my experiences in the previous post Indiewebifying this site. The most important thing however is owning your own site – and allowing the web archive access.

The value of having your own website can be challenged. After all, “owning” stuff and “having control” seem like outdated values in an era when people want to share services rather than own goods (think cars and bikes in big cities). But yet a site can display your professional assets, without depending on the whims of companies such as Twitter, Facebook or Google. Using the IndieWeb-formats for your site helps the search engines (SEO) to find your content and give it a more prominent place. Werdmuller claims that every single career advance in his life comes from his blog.

Then again, nobody says you should limit yourself to just one blog or site. People have multiple interests, and while Facebook loves to capture the whole you, you can decide for yourself to publish several sites, linking or not linking between those sites and even use different names. That’s what I started doing by having this new site for decentralized web stuff rather than use my older MixedRealities site which deals more with virtual and augmented stuff. I publish about the #el30 course on both sites but because I use the same tag all the posts are being captured nicely by the gRSShopper-software the course uses.

Desirable and usable products

Talking about RSS (Rich Site Summary or Really Simple Syndication) and feeds, Werdmuller believes feedreaders have a major comeback. He has knowledge about various projects, but we’ll have to see whether those projects will really go mainstream – even the famous Google Reader never reached mass-audiences and Google cancelled the service to the dismay of academics, journalists and fans of the open web. It all has to do with having a product which is usable by people who barely understand URLs and which corresponds to a real need or desire in the market.

Werdmuller stresses the importance of usability. Web users in general are no experts in using URLs. Ethical software has to be usable by non-experts. Like journalism, research, webdesign has to be human centered. Work with a small group of the people you are trying to help, confront them with prototypes, get feedback and reiterate, so Werdmuller advises. OpenID and a lot of other technologies did not do that and so they failed, the identity is now something people deal with using their social media accounts.

So ethical software should be made in a human-centered way, it should also correspond to real desires and needs of the users, it should be feasible and sustainable in a financial way even when the development is not necessarily for profit. Which means that for creating our decentralized web, sponsorships and academic involvement might be crucial just as it was for the beginning of the internet and the web.

This is an important article by Ton Zijlstra about “distributed technology” and the long tail. In fact, he applies it to Mastodon, a decentralized combination of microblogging and virtual communities. I quote:

This is the notion that tool usage having a long tail is a measure of distribution, and as such a proxy for networked agency. [A long tail is defined as the bottom 80% of certain things making up over 50% of a ‘market’. The 80% least sold books in the world make up more than 50% of total book sales. The 80% smallest Mastodon instances on the other hand account for less than 15% of all Mastodon users, so it’s not a long tail].

and:

Long tail forming as an adoption pattern is a good way then to see if broad distribution is being achieved.

Mastodon is not there yet. It should do more to entice people to start their own instance, their own micro-community. So why don’t I start my own instance? I consider doing so, for instance about VR or virtual worlds. The financial burden would be very modest. I worry more about the moderation duties. I so don’t like getting into fights with people about online behavior. Starting a group about virtual worlds and having to clean up virtual porn images all day does not appeal to me. But maybe there are clever ways to organize a Mastodon instance, avoiding all that hassle.

(Hat tip to Stephen Downes who discussed Ton’s post in his newsletter and on his site)

So I installed the IndieWeb plugin and it authenticates me on Indielogin – I only had to enter my domain name learningwithmoocs.com. Also other members of the IndieWeb-universe were able to comment on this site just by commenting on their own site.

So far so good, but it’s still useful to consult the Getting Started on WordPress on indieweb.org. They suggest a handy testing tool, indiewebify.me.

Several things were not functioning as they should. The explanation is not always easy to follow for a beginner, for instance: “A h-card was found on your site, but it’s not marked up as the representative h-card! Add a u-url property which matches a rel=me link on the same page so this h-card can be identified as the h-card which represents the page.” Rather than complaining, I studied the tutorial.

  • I learned about microformats, which are semantic classes added to HTML tags. There are currently not many WordPress themes which properly implement microformats, the tutorial recommends starting out using either Sempress or Independent Publisher – I use Sempress for now.
  • rel-me links to my other profiles on the web seem to be important. This will enable web-sign-in and IndieAuth using my domain as my identity. The Indieweb plugin adds several common social media site fields to my “Edit User” page in the admin panel. I also have to log into those services and include the URL of my site in the appropriate website fields of my profile so that they point back to my website in return.
  • Now the dreaded h-card, which is like a business card. The tutorial explains in simple terms what I have to do.
  • “Post on your own site, syndicate elsewhere” is a cornerstone of the IndieWeb community, so it is being explained. The quickest and easiest of them is to enable WordPress’s JetPack plugin. However, I prefer to do this manually. I don’t have a huge production and I like to post mindfully on the silos.
  • Webmentions are very cool: “In IndieWeb, we use an open protocol called webmention, which is a W3C recommendation, to allow independently operated sites to interact with each other just the way @mentions do on Twitter and other services.” It’s part of the plugin-bundle.
  • Backfeed. In addition to sending one’s content to silos, ideally one would also like to accept comments, replies, likes, and other replies to these copies back on one’s own site. This is known in the IndieWeb community as backfeed and it is handled by the plugin Bridgy (part of the bundle). There is a separate tutorial for this. Also Bridgy allows for publishing on social media, I decide to allow it for my Mixed_Realities account on Twitter.

I created this site on Reclaim Hosting, the hosting service for ‘educators and institutions’ (and, I guess, for learners in general) co-founded by Jim Groom. Jim previously gave the world the word Edupunk and he facilitated the digital storytelling course ds106.
Learning with Moocs is all about connected learning and more specifically about a number of more technical experiments.

IndieWeb

For now these experiments are being suggested in the course E-Learning 3.0 (#el30, facilitated by Stephen Downes). The course is about learning in a decentralized environment, where learners work on their own projects and own their own data. I posted about this course on my other blog, MixedRealities. In that context I got interested by the “IndieWeb”, that should be a people-focused alternative for the ‘corporate web’. My new site uses the IndieWeb plugin(s) for WordPress.

This bundle of plugins helps to send and receive comments, likes, reposts, and other kinds of post responses using your own site. I’m not sure whether these plugins play nicely with my older MixedRealities site and I’ve no idea about the security aspects, so these and other experiments will be done primarily on this new blog, Learning with Moocs.

OPML

Not visible here is a smaller intervention I did using my site aggregator Feedly. Stephen Downes suggested to use the course OPML-feed to subscribe to the course feeds. I use Feedly a lot, as it helps me to keep track of many sites in a very efficient way. It’s a pity that aggregators never got mainstream adoption. I guess it’s just too hard and too time-consuming for the average web user to get involved with these tools (same applies for social bookmark sites).

As you can see in Downes’ instructional video, finding the OPML-import button in Feedly was not totally self-evident. Stuff like that makes it obvious why adoption of these technology is limited to a niche audience of information professionals and geeks. Anyway, OPML is a useful thing.

gRSShopper

I’ll use Learning with Moocs also for installing Downes’ gRSShopper, “a personal web environment that combines resource aggregation, a personal dataspace, and personal publishing.” I’ll report more extensively about that experiment, as soon as I manage implementing it.

PS – If you have a look at the comments section, you’ll see some IndieWeb-magic taking place there, with me talking on my own site to Matthias who talks on his own site.
