Annotations? Why?
Definitions in Wikipedia: http://en.wikipedia.org/wiki/Annotation
An annotation is metadata (e.g. a comment, explanation, presentational markup) attached to text, image, or other data. Often annotations refer to a specific part of the original data.
Uses by students: Students often highlight or underline passages in books in order to refer back to key phrases easily, or add marginalia to aid studying
Uses in source control: The "annotate" function (also known as "blame" or "praise") used in source control systems such as Team Foundation Server and Subversion determines who committed changes to the source code into the repository. (also: taging/versioning, linking to tickets)
Imaging: In the digital imaging community the term annotation is commonly used for visible metadata superimposed on an image without changing the underlying master image, such as sticky notes, virtual laser pointers, circles, arrows, and black-outs

User Sets - Scalable solution for content curation
User Sets
Content selection criteria: Paintings, fotos, posters Licence: Open for Reuse Visual content:
One person,Few persons,
Groups,(eventually pets) Content quality:
• 500+px
User Sets
Metadata: Title Description Year Collection/Provider
Tags/Classifications: Easy/Mediu/Challenging Selfie/Group/Art German art/Flemish art/etc. Renaissance / Symbolism /expressionism/ etc.
Annotation Model
Open Annotation Core Data Model (OAC) W3C – OA Community Group Interoperable Framework for Annotations (http://www.openannotation.org/spec/core/core.html#BodyTarget)
Annotation Model (implementation)
Annotation Architecture

Moderation
Concerns: Public/Private Annotation Identification of good/popular Annotation/Tags Identification of innapropriate Annotations/Tags Moderation through community Simple Tag to Semantic Tag conversion Semantic enrichment of EDM metadata ?
