9. Metadata Elements
Each information resource is described by using specific data items
These data items are called Elements
10. Metadata Schemas
A metadata scheme is a sets of metadata elements designed for a specific purpose, such as describing a particular type of information resource*
*NISO (2004) Understanding Metadata. Bethesda, NISO Press
11. Metadata Specifications
Stable and widely adopted Metadata Schemas can evolve into Metadata Specifications
The majority of implementers in a particular domain or industryadopts them
12. Metadata Standards
If a standardization organization recognizes a Metadata Specification, then it becomes a Metadata Standard
IEEE LOM and DublicCore for Educational resources (DC-ed) are examples for educational purposes
13. Application Profiles
Metadata Standards or Specifications can be adapted or profiled to meet community context-specific needs
Then, they are called Metadata Application Profiles
14. Adaptation
By imposing restrictions and modifying vocabularies, definitions or elements of the original (base) standard
Aim: Increase interoperability with base standard and not to break interoperability with existing applications
