LEAP resource

Belongs to LEAP 2.0 > classes

Working definition
A digital resource, or a description of a physical resource, relevant to the portfolio holder, other than something that is better represented as an agent or a selection.

Explanation
A LEAP resource is (some) information about a digital or physical resource, which is relevant for portfolio purposes, but outwith the scope of the other portfolio parts, and in particular, not a LEAP agent.

The LEAP resource record may either include the resource itself (e.g. as text), or be a wrapper for an actual (electronic) available resource, or be information about the resource which is not available electronically. In either case, the information enables it to be integrated into the portfolio information structures. The LEAP resource record needs to indicate how the actual resource is to be accessed, either physically or virtually.

A complicating factor is that many external digital resources contain their own metadata. Care needs to be taken that the record of the LEAP resource does not conflict with the metadata within the resource itself.

If one wants to go along with the principle that it is the semantics, not the syntax, which counts, a sensible aim is to minimise the distinction between notes about resources, descriptions of resources, resources that are included in a package, resources with URLs that are available on the web, and resources that are stored elsewhere. Therefore, a LEAP resource can be This does entail a certain amount of inconvenience in the representation: the current view is that this is justified.
 * a file, web resource, or other electronic resource that is either included, attached or linked, where the content is the actual resource
 * a plain text list of resources of any kind where the content lists the resources
 * a description of one or more linkable resources, where the resources are linked via a URL (internal or external)
 * a description of a non-electronic resource, or a resource that is not directly available for inclusion, attachment or linking.

Examples

 * Photograph file
 * Audio clip
 * Video clip
 * Book in paper or electronic form
 * Article in paper or electronic form
 * Web page or web site
 * Text list of named resources
 * Note about where to find one or more resources
 * Painting
 * Structure
 * Vehicle
 * Machine
 * Animal

Alternative terms, with nuances of meaning

 * File - may imply a self-contained computer file, and has overtones of paper files.
 * Resource - this term is used in RDF to mean something extremely general. The meaning here is somewhat narrower.
 * Artefact (GB) / artifact (US) - normally indicates physical things.
 * Product

What it is not

 * A list of separately available resources where the list points to the individual resources, either as LEAP resources or as other URLs. This should be represented as a LEAP selection.
 * A LEAP agent

Predicates
See the notes on LEAP triples for an explanation of what forms of triples there are, and how they are represented here.
 * Particular "Inherited" predicates are given to clarify their likely meaning for this class.
 * "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 instances of the given class(es) as subject and this class as object.

Special note for resources
The following few predicates may refer to When there is ambiguity, it is specified here whether it refers to the resource or the record.
 * the resource itself, particularly if the content is or links to an available digital resource (includes unlinked list)
 * the record of the resource, particularly if the resource is not an available and digital, and there is a description instead of content

Inherited
Particular predicates from item:
 * content (alternative to description) = the content (or true copy) of the resource, (plain, XML CDATA or XHTML) for a resource list, or as URL pointing to an actual resource. If the resource is a list of things, it does not link to its constituent things (otherwise it would be a LEAP selection) and so the content is clearly just the content of the list itself.
 * contribution by &rarr; any LEAP agent that has helped in the creation or maintenance of the resource itself
 * created (resource or record) = date of creation
 * created by (resource or record) &rarr; LEAP agent
 * issued (resource) = date of publication
 * owned by (resource) &rarr; LEAP agent
 * summary = text summarising the content; not text in another role - summary is not intent.
 * supported by &rarr; achievements, activities and goals involving or producing the resource

Direct
The following refer to the resource content, not the record
 * (coverage = plain text -- prefer spatial and temporal)
 * (date ref = date referred to in the resource -- prefer end and start)
 * description (alternative to content) = text literal (plain, XML CDATA or XHTML) of either a resource list, or a description of a resource not available electronically.
 * end = the date(time) at which the resource ceased to exist or be available (applies to non-digital)
 * first &rarr; the first or most important LEAP resource part in a set of lesser resources that make up this one
 * has collaborator &rarr; LEAP agent sharing responsibility for the resource
 * has part &rarr; a lesser LEAP resource which is part of this one
 * has pattern &rarr; a LEAP pattern which the resource is an example of
 * has reply &rarr; LEAP entry; LEAP resource; any URL
 * in reply to &rarr; LEAP entry; LEAP resource; any URL
 * intent = the reason why this resource was created
 * is part of &rarr; a greater LEAP resource
 * is evidence of &rarr; any LEAP achievement, LEAP activity or LEAP assertion for which the resource is evidence
 * presented by &rarr; any LEAP entry or LEAP resource which is a description, account, or representation of the resource (including photographs)
 * presents &rarr; anything which is normally described
 * referenced by &rarr; LEAP entry; LEAP resource;
 * references &rarr; LEAP entry; LEAP resource; any URL
 * spatial = plain text note on
 * the spatial coverage of the subject matter, if a digital information resource
 * the physical location of the resource, if a physical resource
 * start = the date(time) at which the resource came into existence or became available (non-digital)
 * temporal = plain text note on
 * the temporal coverage of the subject matter, if a digital information resource
 * the duration of the availability of the resource, if a physical resource (can also use end and start)

Subclasses
Could subdivide into physical and digital resources, though the usefulness of that distinction seems ever more in doubt.
