Metadata, tagging and search

Below are some general requirements related to metadata, tagging and search as identified by the community (derived from Requirement Outcomes From Planning Workgroups):

Metadata

• Apply standardized metadata to all content
• Automated and synched metadata from existing data systems (student info, registrar, directories, etc)
• Ability to update metadata after publishing
• Updates to metadata propagate through all distribution channels
• Ability to attribute ownership
• Delegate support and admin tasks (renaming/fixing metadata)Versioning of metadata
• Create ontologies of similar terms

Best Practice Examples

• ETH of Zurich is using Dublin Core as a metadata scheme. Together with their library, they are developing a new subset scheme, specifically with regard to the lecture-lecture series-structure and some other features specific to the needs of academic courses. They are now leading an Opencast Metadata Project to further develop this metadata scheme.
• The University of Cambridge uses their own media player
• Interesting discussion about whether the metadata has to be in an independent file or within the media

Tagging

• Ability to tag content
• Collaborative tagging (enable peers/viewers to add tags)

Best Practice Examples

• Northwestern has developed a lecture video player that integrates tagging and search functionality

Search

• Search by transcript
• Search by slides
• Find specific parts within a lecture
• Search across multiple lectures
• Search across institutions and repositories
• Navigate easily through content
• Access to associated content (syllabus, reading list)
