  1. Dear Lorna,

    First of all, thank you for sharing this excellent information. I have a question.

    You mention the mapping between OER Commons internal (very rich) metadata and schema.org (the mapping document you link to, looks somewhat outdated).
    You also mention that “LRMI markup is included in the HTML of resources so it can be found by search engines”.

    This would be very nice.
    Yet, as an example, the OER https://www.oercommons.org/courses/fraction-addition-number-line seems to contain very few schema.org/LRMI metadata – indeed it is practically invisible to the Google CSE. And this seems to be true, unfortunately, for most other OER.

    Where is the schema.org/LRMI markup actually published?

    Thank you,

  2. Hi Renato,

    Many thanks for your comment and apologies for the delay in replying. You’ve raised a very valid issue here and it’s one that my colleague Phil Barker and I will be addressing in a synthesis of all ten funded LRMI implementation projects which we will be publishing shortly.

    You’re correct in stating that the example resource you’ve linked to contains only a few schema.org / LRMI properties, but it does include some, and there in lies the problem. Most OER repositories and aggregators are reliant on resource descriptions produced elsewhere, either harvested from other collections or provided by content creators who rarely have much, if any, experience of cataloguing resources. Clearly platforms and repositories can only encode the metadata they receive, and even OER Commons, which has the most comprehensive metadata creation and curation workflow we have looked at, will rarely use all LRMI properties for any given resource. So although a platform may have implemented LRMI to the extent that it is capable of encoding every LRMI property for every resource, it can not encode this information if it is not provided. It’s the age old problem of education resource description.

    Phil and I would be very happy to discuss this further if you’re interested, so please feel free to drop us a mail at lorna.m.campbell@icloud.com and phil.barker@hw.ac.uk
