*An '''Item''' represents minimal unit of content managed in the system. Each Item comprises of:
**at least one '''MetadataRecord''' - represents one or more metadata descriptions of the overall content represented with the item
**zero or more '''Component''' - represents a single content and at least one metadata description
*For simplicity reasons properties of the objects 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 [https://www.escidoc.org/JSPWiki/en/ObjectManager#section-ObjectManager-Item eSciDoc Item Service]
===Examples===
====Publication items====
*An Item object is an Article published in a journal
**''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:
***[http://pubman.mpdl.mpg.de/pubman/faces/viewItemFullPage.jsp?itemId=escidoc:60092| Publication item presented]
***[http://coreservice.mpdl.mpg.de/ir/item/escidoc:60092 Publication item in the repository]
**Instances with referenced content:
***[http://http://pubman.mpdl.mpg.de/pubman/faces/viewItemFullPage.jsp?itemId=escidoc:95177| Publication item presented]
***[http://coreservice.mpdl.mpg.de/ir/item/escidoc:95177 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:
***[http://faces.mpib-berlin.mpg.de/details/escidoc:43864 Face item presented]
***[http://coreservice.mpdl.mpg.de/ir/item/escidoc:43864 Face item in the repository]
