There isn't an easy way for all the blogs of #OER to talk.
We can build really cool classroom spaces using post types like read, listen, watch, reply and bookmark.
can credential using webmention badges.
can export xAPI with a tiny bit of work
xAPI development paid for by the Department of Defense.
Go ask ten sergeants if they want their lieutenants carrying data that can only be reassembled using government provided devices or data packaged in human readable text.
See what they say.
xAPI is supposed to replace SCORM... which if we are honest meant more within systems... Moodle to Moodle or Blackboard to Blackboard.
But keeping the data structure using micformats makes sense.
Ask ten teachers, Would you like all your student work and their metadata in one file or in two different files? See what the say.
Ohh yeah also ask the teachers if they think they should be able to read said file(s) . Again see what they say.
Let's focus on the nitty gritty of learning. Objective, task, texts, steps, criteria, evidence. Keep the metadata stupid simple.
And keep this stuff where teachers always had it. In their text documents. The paragraphs right in front of them.
I think the affinity group stuff better kept to a credentialing spec. Gonna play nice with xAPI just gonna encourage smallest metadata set possible to ensure data portability.
Learning vocabularies are already bandied about massive. No one really uses them.
I also think it will make more sense to go microformats ->json-> xAPI to create constraints o. n metadata.
xAPI allows any affinity group to create vocabularies. At some point this just becomes words, not data and the consumers stop speaking the same language.
