DLESE Metadata Frameworks

ADN Annotation News and Opps

Constructed from •IMS•GEM•Dublin Corefields that worked best for DLESE

DLESE adopted the old proposed NSDL annotation framework (http://content.nsdl.org/annotation/AnnotationFormat.html)

Own development to mean community need to highlight:•Job•Grants or proposals•Awards•Workshops•Learning or research opporutnities•Call for participation

DLESE web applications use collection records to know about collections regardless of item-level metadata used.

ADN required metadata (web resources)

• Title - the name of the resource (free text)• URL or access information - URL for online resources or access

information to a physical object (free text)• Description - a narrative describing the content, purpose or goal of

the resource (free text)• Subject - topic areas of the resource (controlled vocabulary)• Technical requirements - information related to platform

requirements and browsers (controlled vocabulary)• Resource type - the type of educational resource, such as lab

exercise, tutorials, etc. (controlled vocabulary)• Audience - grade range of the resource (controlled vocabulary)• Copyright - copyright/ usage statement (free text)• Cost - does it cost to access or use (controlled vocabulary)• Resource creator - author/publisher information (free text)• Resource cataloger - cataloger contact information (free text)

ADN Educational Fields - an evolution

IMS Action Taken ADN

Interactivity type

Retained: NSDL-DC adopted the field so kept Interactivity type

Interactivity level

Retained: NSDL-DC adopted the field so kept Interactivity level

Resource type

Retained: GEM, Dublin Core, IEEE-LOM, IMS and NSDL-DC contain resource type; idea also expressed in the DLESE Community Plan can be essential in narrowing search and determining context of use (e.g. lesson plan versus course)

Resource type

Semantic density

Retired: applies to text resources; very subjective; meaning may be ambiguous

Grade range (Learning context)

Retained: DLESE is an education library. Grade information is essential for classifying resources

Grade range

Beneficiary (Intended user)

Retained but new meaning: DLESE resources are used in many different roles to to benefit many groups of people; so adopt GEM fields of tool for and beneficiary and some GEM vocabulary terms

New field: DLESE resources are used in many different roles to to benefit many groups of people; so adopt GEM fields of tool for and beneficiary and some GEM vocabulary terms

Tool for

Difficulty Retired: generally applicable to certain resource types; subjective; meaning may be ambiguous

Typical use time

Retained: Since DLESE resources are used by different groups to benefit different groups, time interacting with a resource may be completely different for each different groups

Typical use time

Language Moved: Removed from educational metadata; made pare general metadata section

Educational description

Educational description

New field: Adopted from GEM to provide a more complete pedagogic description of a resource

Teaching method

New field: Adopted from GEM to provide a more complete pedagogic description of a resource; goal is to provide library users with the instructional goal of the resource without having to go to the resource itself

New field: DLESE Community Plan (pages 9-10 mentions interfacing to standards as important

Content standards

New field: Answers does a student arrive at an appropriate solution based on sound reasoning or process

Process standards

New field: DLESE can be a resource for professional development of educators

Teaching standards
