The Gateway to Educational Materials
|
The four major objectives addressed by the GEM project were to:- Define a semantically rich metadata profile and domain-specific controlled vocabularies necessary to the description of educational materials on the WWW
- Develop a concrete syntax and well-specified practices for its application using current HTML specifications
- design and implement a set of harvesting tools for retrieving the metadata stored as HTML meta tags
- encourage the design of a number of prototype interfaces to GEM metadata
|
From the outset, GEM developed around emerging standards for networked information discovery and retrieval (NIDR). The Dublin Core Element Set (DC) became the base referent for the GEM element set. One of the underlying assumptions of the DC founders was that it would be extensible in two fundamental ways:- Additional elements could be added to meet the needs of particular domains, and
- Its elements could be enriched through the use of a broad range of qualifying "schemes" and "types".

GEM element set includes the whole set of Dublin Core elements (15) and an additional set of 7 new elements:
- Audience. A class of entity for whom the resource is intended
- Cataloging. Information about the individual and/or agency that created the GEM catalog record
- Duration. The recommended time or number of sessions needed to effectively use the entity being described
- Essential Resources. A brief free-text listing of materials essential to the successful use of the entity by the teacher as stated in the entity being described
- Pedagogy. Pedagogical methods and procedures
- Quality. Assessment of the quality of the resource being described
- Standard. State and/or national academic standards mapped to the entity being described
While GEM metadata can be created with any text editor, a publicly available metadata-generating module called GemCat was developed to ease the process of creation by making it possible for the cataloger to focus solely on content. |
