2009-03/Leap2A types

Belongs to the 2009-03/Leap2A specification – see also 2010 developments

This page specifies the types of portfolio item or Atom entry.

The type value is represented with an rdf:type sub-element of atom:entry.

Different types are needed to guide receiving systems on what information is vital to the interpretation of the item, and how to process that information. Types after entry are listed alphabetically.

The relationships given for each type are ones that should be able to be processed properly by importing systems. They have either been used, or their use is clearly foreseen as appropriate and raising no problematic issues.

entry
&lt;rdf:type rdf:resource="leaptype:entry" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#entry" /&gt;

ability
&lt;rdf:type rdf:resource="leaptype:ability" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#ability" /&gt;

achievement
&lt;rdf:type rdf:resource="leaptype:achievement" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#achievement" /&gt;

activity
&lt;rdf:type rdf:resource="leaptype:activity" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#activity" /&gt;

meeting
&lt;rdf:type rdf:resource="leaptype:meeting" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#meeting" /&gt;

organization
&lt;rdf:type rdf:resource="leaptype:organization" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#organization" /&gt;

person
&lt;rdf:type rdf:resource="leaptype:person" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#person" /&gt;

plan
&lt;rdf:type rdf:resource="leaptype:plan" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#plan" /&gt;

resource
NOTE: this has changed significantly in the 2010-07 version.

There is more than one way in Atom of referring to a file. In cases where you have no description, you can link the file from the content, as here. &lt;rdf:type rdf:resource="leaptype:resource" /&gt; or, without CURIEs &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#resource" /&gt; For example, for a single audio reference, e.g. podcast entry, one can use: &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#resource" /&gt; &lt;category scheme="http://wiki.cetis.ac.uk/2009-03/Leap2A_categories/resource_type#" term="Multimedia" /&gt; &lt;content type="audio/mpeg" src="..." /&gt; or, with CURIEs &lt;rdf:type rdf:resource="leaptype:resource" /&gt; &lt;category scheme="schemes:resource_type#" term="Multimedia" /&gt; &lt;content type="audio/mpeg" src="..." /&gt;

In cases where the file has a (short) description, which is just a summary description and not equivalent to the file, put that text into the summary element. This could serve, for example, for the "alt" text associated with photographs or other html graphics.

In cases where there is more than one equivalent representation of the content, if there is a text, html or xhtml one, that should be preferred to put in the content. If not, if any representation is preferred, that should be the one that goes in the content. Other representations should be linked using &lt;link rel="alternate" href="..." /&gt; (See the atom:link documentation.)

selection
&lt;rdf:type rdf:resource="leaptype:selection" /&gt; or &lt;rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#selection" /&gt;

Use of CURIEs
To use CURIEs with Leap2A types, declare xmlns:leaptype="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#" in the opening element of the XML. Examples are given in place.
