In eSciDoc hierarchical structures are build by means of container resources. A container resource refers to its members which are again containers or items. The set of references is represented as structural map (struct-map) inside the representation of a container resource. Additionally a container may contain a table of content (TOC) which contains an ordered selection of members. The TOC does not allow the grouping of members. It contains only direct members of the container resource. Grouping of direct members is not necessary; a hierarchical structure is build by container resources which are linked as members.

Example of a eSciDoc TOC:[edit]

General Idea[edit]

The TOC of a books is divided into two sections.

  • The physical section is generated during the ingestion and contains informations about the scans
  • The logical section can be generated by the user and contains informations about the logical structure of the container. The physical pages are mapped to the logical structure via id.

Attributes[edit]

toc attributes:

  • TYPE: The type of structure this TOC describes
    PHYSICAL = The physical structure
    LOGICAL = The logical structure


div attributes:

  • ORDER: The physical pagenumber of the scan
  • ORDERLABEL: The logical pagenumber of the scan
  • ID: The identification number of this scan (id of the item)
  • TYPE: The type of this structural element (see List of structural element types)
  • LABEL: The elements title
  • VISIBLE: Indicates if this div (and its sub-elements should be displayed when displaying this toc


ptr attributes:

  • ID: The identification of this pointer
  • USE: The type of the file described with this locator
    MIN = thumbnail size
    DEFAULT = Web size
    MAX = Full size
    ITEM = item which contains these files
  • xlink:href: The locator for this file
  • LOCTYPE: The locator type
  • MIMETYPE: The scans MIME type

Previous Ideas[edit]

TOC Representation based on RSS 1.0[edit]

A TOC consists of a RSS items element which is "an RDF table of contents" [1] containing an ordered list of member resources. The items element contains an RDF sequence (rdf:Seq) with RDF list items (rdf:li). A list item refers to a member resource by the RDF resource attribute. 

<rss:items>
	<rdf:Seq>
		<rdf:li rdf:resource="http://localhost:8080/ir/item/escidoc:234"/>
		<rdf:li rdf:resource="http://localhost:8080/ir/container/:111"/>
	</rdf:Seq>
</rss:items>

toc-view[edit]

If the toc-view of a container resource is requested, a RSS channel is generated for delivery. The channel's about attribute is set to the container's URL; title and description are set to the container's title and description. The link element of the channel contains the URL of the requested toc-view. Further the content of the container's TOC is added (rss:items) and a RSS item for each TOC entry is added.

An item element contains information about the referred member (rdf:about attribute). An item contains at least title, description and URL of the member resource as rss:title, rss:description and rss:link. Additionally all DC entries from the triple store pertaining to the referred member are added.

      An RDF table of contents, associating the document's items [5.5] 
      with this particular RSS channel. Each item's rdf:resource {item_uri}
      must be the same as the associated item element's rdf:about {item_uri}.

      An RDF Seq (sequence) is used to contain all the items rather than an 
      RDF Bag to denote item order for rendering and reconstruction.
