Progress report for Educational and Occupational Credentials in schema.org

[This is cross-posted from the Educational and Occupational Credentials in schema.org W3C community group, if you interested please direct your comments there.]

Over the past few months we have been working systematically through the 30-or-so outline use cases for describing Educational and Occupational Credentials in schema.org, suggesting how they can be met with existing schema.org terms, or failing that working on proposals for new terms to add. Here I want to summarize the progress against these use cases, inviting review of our solutions and closure of any outstanding issues. Continue reading

#OER18 Open to all

I spent the last couple of days in Bristol, a city I know well: I went to University there (undergrad, PhD and post doc in physics and materials science), my wife’s parents live there. I’ll be honest, meeting my friends from the OER community in a city of which I am very fond was part of what attracted me to this conference. The theme of the conference, “open to all,” with discussions about OER in the context of colonialism, was less attractive to me. Look at the rest of this blog, you’ll see I am much more comfortable talking about technical specifications, APIs and infrastructure to support the creation and dissemination of OER.

PressBooks and ePub as an OER format.

PressBooks does a reasonable job of importing ePub, so that ePub can be used as a portable format for open text books. But, of course, there are limits.

I have been really impressed with PressBooks, the extension to WordPress for authoring eBooks. Like WordPress it is available as a hosted service from PressBooks.com and to host yourself from PressBooks.org. I have been using the latter for a few months. It looks like a great way of authoring, hosting, using, and distributing open books. Reports like this from Steel Wagstaff about Publishing Open Textbooks at UW-Madison really show the possibilities for education that open up if you do that. There you can read what work Steel and others have been doing around PressBooks for authoring open textbooks, with interaction (using hypothe.is, and h5p), connections to their VLE (LTI), and responsible learning analytics (xAPI).

PressBooks also supports replication of content from one PressBook install to another, which is great, but what is even greater is support of import from other content creation systems. We’re not wanting monoculture here.

Open text books are, of course, a type of Open Educational Resource, and so when thinking about PressBooks as a platform for open text books you’re also thinking about PressBooks and OER. So what aspects of text-books-as-OER does PressBooks support? What aspects should it support?

Using wikidata for linked data WordPress indexes

A while back I wrote about getting data from wikidata into a WordPress custom taxonomy. Shortly thereafter Alex Stinson said some nice things about it:


and as a result that post got a little attention.

Well, I have now a working prototype plugin which is somewhat more general purpose than my first attempt. Continue reading

Not quite certifiable

After a slight delay, last week I received the result of my CMALT (Certified Membership of the Association for Learning Technology) submission.  While most of it was fine, the area which I had thought weakest, Core area 3: The wider context, was rated as inadequate. It has been lovely to see so many people celebrating gaining their CMALT over the last few months; and many of them have said how useful they found it to have access to examples of successful portfolios, which has also been my experience, but in the hope that it is also useful to see examples that fall short, and also in the hope that some of you might be able to provide feedback on improving it, I thought I would share here my unsuccessful portfolio.

Quick update on W3C Community Group on Educational and Occupational Credentials

The work with the W3C Community Group on educational and occupational credentials in schema.org is going well. There was a Credential Engine working group call last week where I summarised progress so far. The group has 24 members. We have around 30 outline use cases, and have some idea of the relative importance of these. The use cases fall under four categories: search, refinements of searches, secondary searches (having found a credential, want find some other thing associated with it), and non-search use cases. From each use case we have derived one or two requirements for describing credentials in schema.org. We made a good start at working through these requirements.

I think the higher-level issues for the group are as follows. First, How do model the aspect of educational and occupational credentials? Where does it fit in to the  schema.org hierarchy, and how does it relate to other work around verifying a claim to hold a credential? Second, the relationship between a vocabulary like schema.org which aims for a wide uptake by many disconnected providers of data, not limited to a specialist domain or a partnership who are working closely together and can build a single tightly defined understanding of what they are describing. Thirdly, and somewhat related to the previous point, what balance do we strike between pragmatism and semantic purity.  We need to be pragmatic in order to build something that is acceptable to the rest of the schema.org community: not adding too many terms, not being too complex (one of the key factors in schema.org’s success has been  the tendency to favour approaches which make it easier to provide data).

Getting data from wikidata into WordPress custom taxonomy

[there is an update of this work]

I created a custom taxonomy to use as an index of people mentioned. I wanted it to work nicely as linked data, and so wanted each term in it to refer to the wikidata identifier for the person mentioned. Then I thought, why not get the data for the terms from wikidata?

Educational and occupational credentials in schema.org

Since the summer I have been working with the Credential Engine, which is based at Southern Illinois University, Carbondale, on a project to facilitate the description of educational and occupational credentials in schema.org. We have just reached the milestone of setting up a W3C Community Group to carry out that work.  If you would like to contribute to the work of the group (or even just lurk and follow what we do) please join it.
