[Open-education] [cc-openedu] Re: [OER-advocacy] Fwd: OER Metadata Standards for Discovery: Call for Collaborators

Hi All,
There are multiple sets of schemas for tagging.  LRMI, CEDS, and so many more.  In my experience, I have found that neither the resource creator or the process/person adding content to an LMS are on the same page.  
I have worked with states, districts, and vendors to harvest content.  Each on having their own metadata fields.  
In US, we had a group of 13 states “adopt” common educational metadata tags so that we could share resources across states easily.  For reasons such as inability to change LOR input fields and lack of understanding this “adoption” failed.  
This is a wide field. I will say that a lesson I learned through the state tagging initiative was we had too many fields with too specific option sets.  I have tagged thousands of resources and manage my states LOR and application teachers use to search our LOR. 
Most Common search fields after grade and subject: 
Keyword
Media type (audio, video, doc, etc)
Instructional type  (interactive, module, lesson, etc)
And rating.  
Everything else is just nice to have.

The common tags I see most content have:
Title, description, subject, grade.  

Interesting topic.

> I think if you can get a tag into Open Graph for representing educational level that would be a great start in making OG useful for representing educational properties. Though there will then be issues about what terms you use to describe the educational level.
