This page describes how sources should provide metadata for our crawling process
The preffered methods are based on exisiting metadata exchange specifications
Our system uses global identifiers for learningResourceType, intendedEndUserRole
Dublin Core LRMI specifies how webpages can include additional metadata for learning objects. They can later be automatically crawled by other systems, including the crawlers from Open Edu Hub.
Example for LRMI Metadata:
(Should be included in the <head> section of your HTML-Page)`
Please note that the included comments are only for reference and must be removed when delivering any JSON data!
Elements marked as "!" are required, "+" means strongly recommended
