LEAP item

Belongs to LEAP 2.0 > classes

Working definition
Any (non-specific) item that is recorded in a portfolio or for portfolio purposes - used as class for information that does not stand by itself, or where the use is unknown.

Explanation
The LEAP item construct exists as the root class, to be distinguished from LEAP predicates. It is a useful collective term covering its subclasses, with predicates that may be common to all classes. It is used as a type of particular pieces of information in two situations:
 * where the information is of unknown type;
 * where the information is not intended to stand by itself, but is inherently related to another item.

Predicates
See the notes on LEAP triples for an explanation of what forms of triples there are, and how they are represented here.
 * "Direct" predicates are those where this class is in the domain of the predicate (but its superclass is not).
 * "Inverse" predicates, if given for reference, are those where the class is in the range, but not the domain, of the predicate.
 * "=" means the predicate expects a literal object: the type of literal may be specified here.
 * "&rarr;" means the predicate expects an object URL referring to an instance of the given class(es).
 * "&larr;" is used for inverse predicates, and means that triples may exist with the given class(es) as subject and this class as object.

Direct

 * contribution by = text
 * contribution by &rarr; LEAP agent
 * content = text; XHTML; XML CDATA
 * content &rarr; any URL
 * created = date
 * created by = text
 * created by &rarr; LEAP agent
 * different from &rarr; LEAP item; external resource
 * follows &rarr; LEAP item
 * included in &rarr; LEAP selection
 * issued = date of publication, date of being made public
 * modified = date of modification of the record (not of modification of any real thing it describes)
 * owned by &rarr; LEAP agent
 * precedes &rarr; LEAP item
 * referred to by &rarr; LEAP item
 * refers to &rarr; LEAP item; any URI
 * reflected on by &rarr; LEAP entry, LEAP resource
 * relation &rarr; LEAP item; any URI
 * same as &rarr; LEAP item of same type, but not a pattern; external resource
 * supported by &rarr; LEAP item
 * supports &rarr; LEAP item
 * summary = text summarising the content; not text in another role - summary is not intent.
 * title = text
