Belongs to the 2009-03/Leap2A specification

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.

Contents

entry

<rdf:type rdf:resource="leaptype:entry" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#entry" /> 
Definition: Any work that is not properly represented as one of the more specific types; anything treated simply as a piece of writing or expression, together with metadata about authoring / creation.
Literals used: (see #any)
Relationships used:
Categories:
Can degrade to: (cannot degrade: this is the most basic type)
Notes: This is listed first as it is the basic type and cannot be degraded. Many miscellaneous things may be represented as entries, including reflexions and assertions. Note that, because entry is the default type, some entries may be without their own content. Receiving systems need to be able to handle these.

Any entry without an explicit type should be interpreted as of this type: it is the default type. Thus, when importing a plain Atom blog feed, all the entries should be handled as if they are of this type.



ability

<rdf:type rdf:resource="leaptype:ability" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#ability" /> 
Definition: EITHER: a general and impersonal definition of some area of knowledge, skill, competence or similar personal attribute, able to be used by anyone as a reference for a claim to possess the ability, or for a goal to achieve the ability, or as an intermediary for exploring pathways in education, employment or life

OR: information about a self-defined and self-claimed ability

Literals used:
Relationships used:
Categories:
Can degrade to: entry
Notes:

Ideally, abilities are handled as follows, which is the first case:

  • impersonal definitions of ability are defined outside the portfolio, typically in a skills or competency framework
  • they can also be defined inside the portfolio, as long as they are authored not by the portfolio holder
  • the portfolio contains claims (which are entries) to abilities and plans to attain abilities
  • evidence of any kind can be linked either to a claim, in its support, or directly to the ability, as more general evidence

However, this first case does not make sense for abilities that are defined, claimed and evidenced by the holder. So we distinguish a second, self-defined case, where the ability entry contains the name (or very short definition) of the ability as the title, and the description of the ability, along with any claim or description of evidence, in the content. In this second case, the ability must be authored by the holder, which it will be by default if no author element is present.



achievement

<rdf:type rdf:resource="leaptype:achievement" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#achievement" /> 
Definition: Describes a state of the world that has been brought about at least partly by the agency of the portfolio holder
Literals used:
  • date point="end" = the actual date at which the achievement was accomplished
  • date point="target" = the date planned for completion, if wanted for comparison
Relationships used:
Categories:
Can degrade to: entry
Notes: An achievement records actual results rather than what was planned for or aimed at as a goal.



activity

<rdf:type rdf:resource="leaptype:activity" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#activity" /> 
Definition: Refers to any activity, experience, occupation, that takes any time and involves the portfolio holder in any way: future, present or past, continuous, interrupted or recurrent; it can comprise a group of lesser activities
Literals used:
  • date point="start" = date activity started or is planned to start
  • date point="end" = date activity ended or is planned to end
  • date point="target" = date by which activity should be completed
  • activetime = time actually spent engaged with activity
  • spatial = place or location or address of activity
  • status = planned, progressing or completed
  • persondata id = id with the organization that supports this activity
Relationships used:
Categories:
Can degrade to: entry
Notes:

Start and end dates are central to activity records. In the case of an activity, the start and end are the overall dates or times. Even if an activity does not have explicit start and end dates represented, being an activity type will clearly indicate that the item is to be treated as an activity. Particularly if dates are missing, the status will say whether it is future, present or past. Persondata id elements record the id for the portfolio holder connected to this activity, which may for instance be a period of study, employment, or membership. For this to work, there will need to be exactly one organization that "supports" this activity.



meeting

<rdf:type rdf:resource="leaptype:meeting" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#meeting" /> 
Definition: Refers to a meeting, relevant to the portfolio holder, involving two or more people, held in a particular location between specific times, which may have agenda and outcomes of interest to the portfolio holder
Literals used:
  • date point="start" = scheduled or actual start time of meeting
  • date point="end" = scheduled or actual end time of meeting
  • spatial = place or location or address of meeting
  • status = planned, progressing or completed
Relationships used:
Categories:
Can degrade to: activity
Notes: This is a very important class of items in the PDP world, with its own special elements.

Meetings can either be records or be calendar or diary items. Systems claiming to be able to import meetings must make sensible use of time and place information provided.



organization

<rdf:type rdf:resource="leaptype:organization" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#organization" /> 
Definition: Any commercial, social or political entity of interest to the portfolio holder, beyond an individual person, which may act as an agent, including a group of people acting together, or represented together as a unit.
Literals used:
  • orgdata = contact information and other data about the organization
  • spatial = postal addresses, or text description of the spatial/geographical scope of the organization
Relationships used:
Categories: (none yet defined, but could easily be)
Can degrade to: entry
Notes:

The "activity" supported by an organization can be simply a record of membership or affiliation. At present, this is not given a separate type in Leap2A. Organizations can have units as their parts, but we will try to avoid the idea that a person can be literally "part of" an organization. Systems may or may not hold information about organizations separately. Often, names of educational institutions or employers will be given simply as names, and recorded as part of the title or content of activities.


person

<rdf:type rdf:resource="leaptype:person" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#person" /> 
Definition: Information about the portfolio holder, or referring to another individual person of relevance to the portfolio holder
Literals used:
  • persondata = various CV-related and contact information.
  • spatial = postal addresses
Relationships used:
Categories:
Can degrade to: entry
Notes: This is where all the personal information for the portfolio holder, including addresses, will go.

Also, all other relevant people can be listed with as much or as little personal information as appropriate. A person as defined here can be the author of any entry. If there is more than one person defined in a Leap2A export, it is essential that the feed author is linked to the person entry for the portfolio holder.



plan

<rdf:type rdf:resource="leaptype:plan" /> 

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#plan" /> 
Definition: A considered plan intended to achieve one of the portfolio holder's goals or purposes, typically involving several actions or lesser goals
Literals used:
  • date point="start" = scheduled or actual starting date of this plan
  • date point="end" = scheduled or actual end date of this plan
  • date point="target" = date by which goal should have been attained
  • status = planned, progressing or completed
Relationships used:
Categories:
Can degrade to: selection
Notes: A normal action plan has a target date in the future, and is probably linked to a goal, which may have the same target date.

The plan describes the way to achieve the desired situation. It answers the question "how are you going to achieve this goal?" There may be a plain piece of text describing the plan, or how the parts of the plan are articulated (the content of the plan), and there may be linked activities or goals (or possibly entries) as parts. Plans typically have a target date: the date on which the goal is meant to be achieved.



resource

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.

<rdf:type rdf:resource="leaptype:resource" />

or, without CURIEs

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#resource" /> 

For example, for a single audio reference, e.g. podcast entry, one can use:

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#resource" />
<category scheme="http://wiki.cetis.ac.uk/2009-03/Leap2A_categories/resource_type#" term="Multimedia" />
<content type="audio/mpeg" src="..." />

or, with CURIEs

<rdf:type rdf:resource="leaptype:resource" />
<category scheme="schemes:resource_type#" term="Multimedia" />
<content type="audio/mpeg" src="..." />

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

<link rel="alternate" href="..." />

(See the atom:link documentation.)

Definition: A digital resource, or a description of an unlinked resource (often a physical resource), relevant to the portfolio holder, other than something that is better represented as a person, organization or selection
Literals used:
Relationships used:
Categories:
Can degrade to: entry
Notes: A resource, for Leap2A purposes, can be one of three things:
  • a file, web resource, or other electronic resource
    • either given in the content as text, html or xhtml
    • or referred to as the content "src" (in this case the mime type should be given), and
      • either included as a file packaged with the export, with the src attribute giving the relative address in the package
      • or available on the web at a URL given in the src attribute of the content
    • a short, summary description may be given in the summary element
    • any alternate form of the resource may be represented as a link, with the attribute rel="alternate"
  • a plain text note of resources of any kind where the content lists the resource(s)
  • a description of a non-electronic resource, or a resource that is not directly available for inclusion, attachment or linking. In this case, the atom:type should NOT be the mime type of the resource. The mime type of the resource may be described in the (text) content.

Note that other items can also play the role of resources, and this will be obvious by their relationship (generally "supports") to the main item under consideration. Where there is an entry of type person who supports something, that may be interpreted in the context of that item as a resource of type people. Where there is an entry of type selection supporting something, the selection may be given a resource category, and thus be equivalent in meaning to a plain text list resource with the same category and equivalent content. In each case, if there is only one resource, or the resources are of the same type, the entry may be given a resource type category. If there are different types of resource mixed together, the resource type may be left out, or given as "Unclassified". Care needs to be taken to distinguish between information about the resource (its meaning, etc.) and records relating to the entry (metadata). Resources authored by the portfolio holder can be the artefacts that are evidence of their abilities.



selection

<rdf:type rdf:resource="leaptype:selection" />

or

<rdf:type rdf:resource="http://wiki.cetis.ac.uk/2009-03/Leap2A_types#selection" />
Definition: a set of related portfolio items or external resources, typically selected by the portfolio holder for a particular purpose and for display to a particular audience
Literals used:
Relationships used:
Categories:
Can degrade to: entry
Notes:

This type could also be called collection or presentation, all of which are central in portfolio thinking, as portfolio items are typically collected, then selected for use in presentations. Selections exist only in virtue of what is in them, so there should be no ambiguity in giving the relationship as has part. The whole-part relationship should be used only for immediate parts. If A is part of B, and B is part of C, A should not also be given as part of C. A summary of this type of entry may refer more specifically to the rationale for the selection, but the content or description, if any, will be taken to refer to all of the parts as well as possibly the selection itself, as with a blog collection or feed. If the selection as such has no content, it may be presented by an entry, which may or may not be part of the selection.

Note also that the selection type is not the only way of representing hierarchical structure or nesting. The types #activity and #plan can also contain parts of the same type, and if there is a hierarchical structure to be represented that naturally fits the activity or plan type, that is strongly preferred to using the selection type.



any

Literals:
  • author
  • title
  • published, updated
  • content: this normally contains the main text associated with the item
  • summary: this is not required, but if used should give just a summary of the content, as is the intention in Atom
Relationships:
Categories:
Notes: These Literals, relationships and categories can apply to any type, in addition to the ones specified for each particular type.

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.
