Who is using LRMI metadata?


One question that we always get asked about LRMI is “who is using it?” There are two sides to this, use by search service providers and use by resource providers, this post touches on the latter.

In phase 2 of the LRMI project, various organizations were given small amounts of money to implement LRMI in their systems and workflows. Those organizations are listed on the Creative Commons web site, and Lorna is in the process of gathering together the lessons they learnt which will be reported back shortly. Perhaps more importantly, at least from the point of view of sustainability, are implementations that arise spontaneously, either by organizations with learning resources to disseminate who make a conscious decision to use LRMI, or those who in using schema.org markup find that one of the properties that LRMI added is appropriate.  Of course no one doing this is under any obligation to inform us of what they are doing, so it is harder to keep track of such use. Fortunately the Google Custom Search Engine Wilbert and I cobbled together  can be used to discover such implementations. It’s a bit hit-and-miss, you need to search for common topics (Math, English) and trawl through the results for new sites,  but it’s better than nothing.

This blog has moved…

…this is the last blog post I shall make here, comments are closed.

I will continue blogging about my Cetis work from my general work blog, “Sharing and learning” This is so that I don’t have to maintain separate sites for Cetis work, other projects and reflections on teaching. My posts about Cetis work will still be aggregated into the Cetis blogs site which is probably how most of you get here, but if you’re used to coming direct to this page please change your bookmarks / feed settings:

Announcing “What is schema.org?”, a new technical briefing paper from Cetis

As part of my work with Cetis  for Creative Commons on managing the Learning Resource Metadata Initiative (LRMI), Cetis today publish a new technical briefing paper “What is schema.org?”.  LRMI is built on and expands schema.org so that it can be used to describe educationally significant characteristics of resources. I often find when explaining LRMI at a technical level, mostly I am explaining schema.org, hence this briefing as the first of a series coauthored by me and Lorna M Campbell, planned to explain LRMI.

Filtering Google custom searches on LRMI alignment values

As I said, Wilbert and I are building a Google custom search engine for LRMI-tagged pages. We got a basic search that finds pages that have an educational alignment and matches a search term. Next step is using the properties of the educational alignment to filter the search result based on things that teachers care about. Our friends at a11y showed us how to do the filtering based on properties with their search demo which uses the search modifier
to filter results that have schema.org markup showing that they contain captions.

Building a Google custom search engine for LRMI-tagged pages

Wilbert and I are spending the day trying to create a search engine for finding learning resources by searching LRMI-tagged web pages. A bit of code sprint if you like.

First attempt: standard custom search engine hosted by Google.
1. Go to https://www.google.com/cse/ set up new search engine. Choose option to “Restrict Pages using Schema.org Types” to CreativeWork.

We’ll use “Declaration of Arbroath as a test search. By way of baseline, here’s the what we get just searching Google for that:

LRMI, Open badges and alignment objects

I had the pleasure yesterday to talk on the Mozilla Open Badges community call about how LRMI and Open Badges may intersect. Open Badges are a means of displaying digital recognition of skills and achievements, there’s a technical framework behind the badges that offers the means of providing data in support of the claimed achievement. A particular part of this technical framework is the assertion specification, which includes a pointer from each badge to “the educational standards this badge aligns to, if any”.  This parallels the LRMI alignment object  very closely: in short the educationalAlignment property that LMRI added to schema.org allows encoding of statements along the lines of “this resource [teaches|assess|requires|has level] X” where X is some point in an shared educational framework, e.g. of attainment standards, topics or educational levels or shared curriculum.

Open, Education

This is a longish summary of a presentation I gave recently, covering why I was talking, the spectrum of openness, the ways of being open, the range of activities involved in education and how open things might apply to those activities. You may want to skim through until something catches your eye :)
