	Chapter 3. Listing Content

The individual content items are described in the content:content element using a range of descriptive fields. For example, the following listing is the output for one content item:

<content:content xmlns:cmap="http://lex.thelearningfederation.edu.au/cmap/2003/06/" xmlns:imsmd="http://www.imsglobal.org/xsd/imsmd_v1p2" xmlns:lexmd="http://www.thelearningfederation.edu.au/lexmd_v1" xmlns:xi="http://www.w3.org/2001/XInclude" exist:id="1" exist:source="exchange:L2055:1.0">

The following table describes the elements returned in the above output

Element Name	Contents
content:source	The source repository for this object. This is an identifier specified by the upstram BELTS server and serves to distinguish content that comes from different external repositories.
content:id	The identifier of the content. This is the identifier used by the external repository for this content item.
content:version	The version of this object.
content:local	Whether this object is stored locally on the BELTS server. For downstream clients, the value of this field will alway be `true`.
content:published	Whether this object is published on the BELTS server. For downstream clients, the value of this field will alway be `true`.
content:last-modified	The timestamp when this object was last modified. This is a long value indicating the number of milliseconds since January 1, 1970.
content:size	The size (in bytes) of the downloadable content file for this object.
content:searchable	The searchable data for this object. This information is used internally by BELTS but may be used by the downstream client for their own purposes.
content:metadata	The IMS and TLF metadata associated with this learning object. The content of this element is taken directly from the learning object. For further information on the content of this element, please refer to the Metadata Application Profile specification in the TLF Documents section at http://www.thelearningfederation.edu.au.
content:outcomes	This element describes how the content item assists in reaching the outcomes described by the Curriculum Organiser for the BELTS site. The Curriculum Organiser is described in more detail in the BELTS documentation at the BELTS SourceForge site.

3.2.1. Searchable Content Details

The content:searchable element contains a number of fields that are used by BELTS during content searches. These fields are taken from the various metadata elements and provide a summary of the information known about the object in a format suitable for searching. The following is an example of the elements contained within the content:searchable element:

  <content:searchable>
    <content:title>Arrays: word problems with products from 30 to 50</content:title>
    <content:tlf>learning-object</content:tlf>
    <content:description>Read a number problem and think about how to solve it. For example, when 38 is divided by a number, the answer is 7 with a remainder of 3. Write the problem as a multiplication or division number sentence with a missing number. Think about multiplication or division facts to find the missing number. Test your answer by making an array of equal rows and columns to show the multiplication or division fact and the remainder. This learning object is one in a series of ten objects.</content:description>
