ESciDoc Logical Data Model/Container

In PROGRESS

Introduction

This page provides general overview on the Container resources within the eSciDoc repository. General introduction available at eSciDoc Logical Data Model page.

Model description

• A Container represents aggregation of content resources such as other Items and/or Containers. Each Container comprises of:
  • at least one MetadataRecord i.e. one or more metadata descriptions of the overall content of the container
  • zero or more members of type Item or Container expressed with the "structural map" of the container

UML Diagram

• For simplicity reasons properties of the objects and item resource details are not represented on the diagram. Properties are managed by the escidoc repository itself and may change during time. For more information on the properties and ther usage please check the documentation available at eSciDoc Container Service. Data model details for Item resource is available at eSciDoc Logical Data Model-Item.

Examples

Faces Albums

• A Faces Album is an aggregation of Face Items that consists of:
  • MetadataRecord: contains the bibliographic metadata (title, author, publication type e.g. journal article, author affiliation, year of publication, etc.) structured accordingly a particular metadata profile
  • Component1:one published version of the fulltext of the article
    • Component1.MetadataRecord1: title, description of the full-text, reference to the license
    • Component1.MetadataRecord2: technical metadata of the file (e.g. generated from JHove)
    • Component1.Content: the actual bytestream e.g. PDF or reference(link) to the content external to the repository
  • Component2:supplementary material e.g. data on results provided in the fulltext of the article
    • Component2.MetadataRecord1: title, description of the file
    • Component2.MetadataRecord2: technical metadata of the file (e.g. generated from JHove)
    • Component2.Content: the actual file or reference(link) to the content external to the repository
  • Instances with actual content:
    • Publication item presented
    • Publication item in the repository
  • Instances with referenced content:
    • Publication item presented
    • Publication item in the repository

Face items

• An Item object is an image of a facial expression, showing emotions such as: happiness, anger, saddness etc.. Each item contains two sets of image captions of the expression (each face/expression was captured twice). Sets are named "a" for the first image caption and "b" for the second caption.
  • MetadataRecord:contains metadata of the face and expression such as: gender, age, emotion, age-group
  • Component1: an image that captures the facial expression
    • Component1.MetadataRecord1: contains information on the image caption set; type of the image such as: original resolution, thumbnail or web resolution.
    • Component1.MetadataRecord2: technical metadata of the image (e.g. generated from JHove)
    • Component1.Content: the actual bytestream e.g. JPEG file itself
  • Component2: an image that captures the facial expression
    • Component2.MetadataRecord1: contains information on the image caption set; type of the image such as: thumbnail
    • Component1.MetadataRecord2: technical metadata of the image (e.g. generated from JHove)
    • Component1.Content: the actual bytestream e.g. JPEG file itself
  • Instances:
    • Face item presented
    • Face item in the repository
