OMM ToC Draft

Proposal: Table of Contents (ToC)

Mandatory Elements

The ToC is composed of records, which contain meta data from the OMM-blocks. Each record of the ToC contains the following mandatory elements:

• Title
• Date
• BlockId
• Namespace

Additional Elements

In addition to these mandatory elements the following elements will be used:

• Creator
• Format
• Type
• Subject

The account of these elements is defined in the section "Block Meta Data". A ToC-block is identified with the namespace http://www.w3.org/om/toc and contains the same meta data as ordinary OMM-Blocks (title, date, blockid, namespace, ...). The data of this blocks contains the ToC-records in XML-format (see ToC-example). To describe a virtual ToC the data section of the OMM-block remains empty and it is up to the application to create the ToC on the fly by reading and sorting the metadata of all OMM-blocks.

Mapping to SemProM Metaformat Version 1.0

• Title is a new element
• Date can be mapped to the Creation-Date of the block
• BlockId can be mapped to the BlockId of the block
• Namespace can be mapped to the BlockType of the block
• Creator can be mapped to the Creation-Author of the block
• Format can be mapped to the ContentType of the block
• Type is a new element
• Subject can be mapped to the Meta Tags of the blocks

This approach allows a mapping from the SemProM Metaformat to the OMM-format but not necessarily vice versa.
