We’ve launched a new services group.

 

 

Some Background

For years, we have relied on our products to be the solution to a number of complex problems facing companies that use learning standards. If you’re building an LMS or authoring tool and you need AICC or SCORM or, more recently, xAPI, we have a product that can do the heavy lifting. That’s been our bread and butter.

But we also have insights from years of thinking about experiential data and hearing how customers report on it. And we know that the problem isn’t always solved at the immediate boundary of our products.

It’s those considerations that brought our services group to life.

What We Do

We help vendors and organizations consider how to use learning standards to accomplish their goals. These goals include delivering the learning material to their people and selling their products to discerning buyers.

We work on problems related to the learning standards AICC, SCORM, and xAPI.

In the case of xAPI, the newest of the standards, the off-the-shelf solutions are less mature. Listening carefully and collaboratively helps us build better products, but it also helps us get you the right solution now.

Of course, we haven’t stopped thinking about AICC and SCORM.

Where You Come In

We want you to ask us a question. You can learn more about how we’re responding to the questions we’ve already heard here. These are things we anticipate. Maybe something on this list prompts a question you were getting ready to ask. So, ask away– we’re listening and ready to help.

Semantic Interoperability

You’re going to hear us talk a lot about semantic interoperability this year. So we might as well present a working definition.

Semantic interoperability is when information—the meaning behind captured data—is 
portable and well understood by any subsequent system requesting and reviewing it.

 

Why will we be talking about it a lot? Because without semantic interoperability, the Experience API (xAPI) has a limited future.

For us, semantic interoperability in xAPI will be achieved when there is a generally accepted information model. We expect profiles to help with this a great deal. There’s a strong possibility that collaborative work between ADL and IMS could help a great deal.

Then: Too Many Constraints

Consider SCORM, the usage of which remains widespread in LMSs everywhere. The CMI data model leveraged by SCORM is closely linked to its information model. There is a finite set of data that can be recorded about the types of learning experiences common to online training, and summarizing information from that data is a relatively straightforward exercise. So straightforward, in fact, that practitioners have long cared primarily about a big four—score, completion, satisfaction (i.e., pass/fail), and duration. SCORM makes requesting and understanding the big four easy.

Now: Too Much Flexibility

xAPI, on the other hand, is fundamentally a communication protocol applied as a specification for elearning. In xAPI, apart from a few familiar holdovers from SCORM (the big four, native support for interactions), there is no limit to what can be captured about a given learning experience. One could literally choose any verb available in any language. Or one could create a new activity definition to describe any type of experience.

Can you imagine how difficult it would be to report on data with so few constraints? We can. Because we’ve been trying.

Needed: Leadership

Even when there is consensus that a concept has sufficient value to merit a profile, there can be difficulty. Take video, for instance. Not only is there a profile in our Registry, there’s also a Community of Practice still working on a version. If there are multiple working versions of what data to capture, then how is a reporting system attempting to derive meaning about “video” supposed to do so?

We think the answer right now is: leadership. The concept of Registry has utility to semantic interoperability in xAPI, and we have a feature roadmap for it. Still, we recognize the difficulty in a single industry participant to establish credibility and trust.

What would alternatives look like? We think ADL could assert an information model. As a subtle alternative, ADL could host a collaborative process with some authority. This might look like the establishment of a baseline with a community process similar to how the specification itself operates now—managed workflow in GitHub supported by regular calls.

Expect to hear more from us on this topic because we think it’s critical to the future success of xAPI.
