MetaMedia offers:
A flexible on-line environment to create,
store, annotate, and share media-rich
documents
MetaMedia allows:
Faculty to build subject-specific miniarchives for teaching and learning
MetaMedia supports:
Educational innovation through creative
use of multimedia materials

Background
Previous projects in the Humanities at MIT either:
- stored data in proprietary formats, or
- created flat web pages
Common problem:
- Media and metadata could not be extracted and reused
Missing resources:
- to rebuild projects
- to support similar approaches in different projects
Dr. Kurt Fendt, Comparative Media Studies, MIT <[email protected]>
Vision
- Separate content, presentation, and logic
- Leverage existing components for new projects
- Enable easy creation of new media projects
- Provide upload and annotation mechanisms
- Allow users at different institutions to collaborate
- Build a system in which components can be exchanged
- Offer flexible ways for content creation and presentation

Open Standards
The MetaMedia framework stores metadata in
standard markup formats, such as Dublin Core and
Text Encoding Initiative (TEI).
Separation of Content and Presentation
Storing markup in standard formats allows MetaMedia
to separate media content and its presentation cleanly
and simply.
Extending Project Lifecycles
Separating content and presentation extends each
project’s lifetime, as markup can be output in XML
and migrated to new software when necessary.
Dr. Kurt Fendt, Comparative Media Studies, MIT <[email protected]>
User Collaboration
Integrated permissions management allows users to
add to and share materials in the repository,
encouraging constructivist models of learning and
research.
Exchanging Content
Supporting open markup standards allows related
groups in Humanities Computing to exchange media
and annotations, thus fostering academic collaboration
within and across institutions.
Room to Grow
Storing content in rich markup formats form the
start allows projects to grow into more sophisticated
functionality without starting from scratch.
Dr. Kurt Fendt, Comparative Media Studies, MIT <[email protected]>
Multimedia Markup
Multimedia markup standards allow users to annotate
images, audio, and video, making MetaMedia a crossmedia repository platform.

Design Considerations
- Serve content to the web and ‘fat clients’ (Java applications)
- Content to be exportable and importable in standard markup
formats
- Document-centric model
- Problem: semi-structured vs. structured content
- XML Markup formats:
• Dublin core: standard bibliographic data
• TEI: electronic representation of printed documents
• DocBook: generic electronic books
• MPEG-7: markup for images and video
• RDF/Annotea: ‘post-it’ type notes
• IMS/SCORM: learning objects
- Collaboration and transactionality

- Repository viewer/sectioner
- Workspace module
- Workflow module
- Forums
- Annotation module
- Multimedia essay module
- Individual project user interfaces
- User login/registration
- User preferences
- Administration pages

The Open Knowledge Initiative™ (OKI) is defining an
open and extensible architecture for learning
technology specifically targeted to the needs of the
higher education community.
OKI provides detailed specifications for interfaces
among components of a learning management
environment, and open source examples of how
these interfaces work.
The OKI architecture is intended to be used both by
commercial product vendors and by higher education
product developers.
It provides a stable, scalable base that supports the
flexibility needed by higher education as learning
technology is increasingly integrated into the
education process.

DSpace is an open source software platform that
enables institutions to:
• capture and describe digital works using a
submission workflow module
• distribute an institution's digital works over the
web through a search and retrieval system
• preserve digital works over the long term

OCW is a large-scale, Web-based electronic publishing
initiative at MIT. Its goals are to:
• Provide free, searchable, coherent access to MIT's course
materials for educators in the non-profit sector, students,
and individual learners around the world.
• Create an efficient, standards-based model that other
universities may emulate to publish their own course
materials.
