General Information
Joint Information Systems Committee

Leap2A is an outcome of the JISC CETIS (JISC Innovation Support Centre - Centre for Educational Technology and Interoperability Standards) project called InterOperability Project. It sets up the framework for the ePortfolio data interoperability.
This specification is intended to cover the representation of several kinds of information, centred around individuals, who collect, create and use their own information. Much of this information is typically of the kind that can be used for individuals' learning, but rather than being learning materials authored by an educator, the information covered by this specification is authored by the individuals themselves, about themselves. The individual, whether pupil, student, apprentice, employee or none of these, may be thought of as a learner for our purposes. If a learner reflects, on the information collected, or on other things, the expression of that reflection will be one kind of information that will take a natural place among the other kinds of information dealt with here.
The learner may also make selections from this information for presentation to other people, serving as evidence of the learner's learning, abilities, achievements, etc. The information is therefore considered for our purposes to be portfolio information, the learner may be thought of as the portfolio holder, and each presentation as a portfolio. Portfolio holders may not own all the information presented, but they will typically control access to it by others. Digital artefacts created or authored by the learner are one important category of information that can be used in electronic portfolios, and that therefore is covered by this specification.
It is not the purpose of this specification to cover information gathered by others about an individual, over which that individual has no access or control.
One of the ways in which learners express their reflections, and may record other information, is through blogs (weblogs). The Atom Syndication Format is a ubiquitous specification covering blogs, and it is designed to be extensible, so it has been chosen as the basis of this present specification. Atom by itself does not provide a rich enough vocabulary to distinguish all the significantly different kinds of portfolio information. This specification selects from Atom and extends it, to be able to represent the needed distinctions.
This specification is intended to be permissive rather than exclusive. It specifies what may be "expected" in a transfer of portfolio information as specified. Very few elements are mandatory, except where specified as mandatory within Atom. Other elements may be present, and should not cause processing errors, but may not be interpreted correctly, or at all. |
Relationship to LEAP 2.0
Leap2A is the specification, based on Atom, developed and agreed by the partner developers. LEAP 2.0 is a wider, forward-looking framework, assembled by Simon Grant using ideas from many others, and kept up to date to reflect all developments in Leap2A. LEAP 2.0 is more clearly directly based on Semantic Web concepts, and does not have the validity of having been agreed or implemented by anyone. LEAP 2.0 therefore acts as a conceptual testing ground, where ideas can be put in place ready for possible agreement and adoption within Leap2A. Leap2A is agreed and relatively stable, currently being steadily extended, but LEAP 2.0 constructs that are not part of Leap2A may be changed or abandoned at any time, when new insight or agreement emerges. |

The Structure of portfolio information
Leap2A has an Atom extended XML schema that covers the following portfolio fundamental information types:
- digital artefacts made by the portfolio holder
- short expressions by the portfolio holder
- information about the portfolio holder
Selection of those units of information items can appear together as portfolio items and can be imported or exported individually or together from different systems.
Digital artefacts: (audio, video, multimedia, plain text) have associated information - metadata (author, date, title,). Portfolio holder presents them as evidence of their abilities.
Short expressions: (blog entries,) that can be understood in its context. They nevertheless exist and can be managed separately. Metadata stores information about dates, authors, rights, Portfolio holder.
Items: Information in e-portfolio and Leap2A is grouped into items. Each item can be presented as Atom entry (each item corresponds to just one entry). Each item has type. Each item type has literal attributes, relationships and categories. Items are connected (Leap2A predicates) with metadata (literal values, properties). Similar predicates are used for connecting different items with each other. Data can be grouped in following groups:
- Literal metadata - related directly to item
- Personal data - not related with portfolio core processes; e.g. name, nationality, contacts, ID
- Organizational data - part of personal data - awarding and provider organizations.
- Structured content - similar to references but also related with page layout
- Relationships - data about links between items and other entries.

Correspondence with Atom Structures
Leap2A is based on Atom Syndication Format. Atom was designed for exchanging the blog feeds but fits also for exchanging the portfolio information. Information exchange is based on the XML format. In the Leap2A the Atom is extended because Atom's vocabulary is not enough for representing all information stored in e-portfolio. Very few elements of Leap2A are mandatory, expect if they are mandatory in Atom. |
