InLOC is a European project organised to come up with a good way of communicating structures or frameworks of competence, learning outcomes etc. We've now produced our interim reports for consultation: the Information Model and the Guidelines. We welcome feedback from everyone, to ensure this becomes genuinely useful and not just another academic exercise.
The reason I've not written any blog posts for a few weeks is that so much of my energy has been going into InLOC, and for good reason. It has been a really exciting time working with the team to develop a better approach to representing these things. Many of us have been pushing in this direction for years, without ever quite getting there. Several projects have been nearby, including, last year, InteropAbility (JISC page; project wiki) and eCOTOOL (project web site; my Competence Model page) — I've blogged about these before, and we have built on ideas from both of them, as well as from several other sources: you may be surprised at the range and variety of "stakeholders" in this area that we have assembled within InLOC. Doing the thinking for the Logic of Competence series was of course useful background, but nor did it quite get there.
What I want to announce now is that we are looking for the widest possible feedback as further input to the project. It's all too easy for people like us, familiar with interoperability specifications, simply to cook up a new one. It is far more of a challenge, as well as hugely more worthwhile and satisfying, to create something genuinely useful, which people will actually use. We have been looking at other groups' work for several months now, and discussing the rich, varied, and sometimes confusing ideas going around the community. Now we have made our own initial synthesis, and handed in the "interim" draft agreements, it is an excellent time to carry forward the wide and deep consultation process. We want to discuss with people whether our InLOC format will work for them; whether they can adopt, use or recommend it (or whatever their role is to do with specifications; or, what improvements need to be made so that they are most likely to take it on for real.
By the end of November we are planning to have completed this intense consultation, and we hope to end up with the desired genuinely useful results.
There are several features of this model which may be innovative (or seem so until someone points out somewhere they have been done before!)
- Relationships aren't just direct as in RDF — there is a separate class to contain the relationship information. This allows extra information, including a number, vital for defining levels.
- We distinguish the normal simple properties, with literal objects, which are treated as integral parts of whatever it is (including: identifier, title, description, dates, etc.) from what could be called "compound properties". Compound properties, that have more than one part to their range, are a little like relationships, and we give them a special property class, allowing labels, and a number (like in relationships).
- We have arranged for the logical structure, including the relationships and compound properties, to be largely independent of the representation structure. This allows several variant approaches to structuring, including tree structures, flat structures, or Atom-like structures.
The outcome is something that is slightly reminiscent both of Atom itself, and of Topic Maps. Both are not so like RDF, which uses the simplest possible building blocks, but resulting in the need for harder-to-grasp constructs like blank nodes. The fact of being hard to grasp leads to people trying different ways of doing things, and possibly losing interoperability on the way. Both Atom and Topic Maps, in contrast, add a little more general purpose structure, which does make quite a lot of intuitive sense in both cases, and they have been used widely, apparently with little troublesome divergence.
Are we therefore, in InLOC, trying to feel our way towards a general-purpose way of representing substantial hierarchical structures of independently existing units, in a way that makes more intuitive sense that elementary approaches to representing hierarchies? General taxonomies are simply trying to represent the relationships between concepts, whereas in InLOC we are dealing with a field where, for many years, people have recognised that the structure is an important entity in its own right — so much so that it has seemed hard to treat the components of existing structures (or "frameworks") as independent and reusable.
So, see what you think, and please tell me, or one of the team, what you do honestly think. And let's discuss it. The relevant links are also available straight from the InLOC wiki home page. And if you are responsible for creating or maintaining structures of intended learning outcomes, skills, competences, competencies, etc., then you are more than welcome to try out our new approach, that we hope combines ease of understanding with the power to express just what you want to express in your "framework", and that you will be persuaded to use it "for real", perhaps when we have made the improvements that you need.
We envisage a future when many ICT tools can use the same structures of learning outcomes and competences, saving effort, opening up interoperability, and greatly increasing the possibilities for services to build on top of each other. But you probably don't need reminding of the value of those goals. We're just trying to help along the way.
