Quality Metrics for
Learning Object Metadata Xavier Ochoa, ESPOL, Ecuador Erik Duval, KULeuven, Belgium
2.
Standardization and Interoperability
of Learning Objects Repositories has solved the “chicken and egg” problem… …but has created new ones.
3.
The production, management
and consumption of Learning Object Metadata is vastly surpassing the human capacity to review or process these metadata.
4.
5.
6.
But we cannot
measure the quality manually anymore…
7.
… but is
a good idea to follow the same quality characteristics.
