Introduction

What are called "properties" or "predicates" in RDF are the connections between subject resources and, on the one hand, other resources, or literal values.

In Leap2A, predicates connect Leap2A items with other Leap2A items, and items with values that are properties (sometimes called "metadata") of those items. It is convenient to have these all listed together, so there can be one namespace for use with all of them. The definitions of the predicates are held on the relevant pages, linked to from here.

The predicates in the table below are documented further

• in Leap2A/personal data for persondata
• in Leap2A/organizational data for orgdata
• in Leap2A/literals if they are other elements with literal values, within portfolio items;
• in Leap2A/relationships if they are relationships between portfolio items (entries);
• in Leap2A/categories if they are to do with categories.

Follow the links at the end of the appropriate row.

For completeness of documentation, Atom-namespaced predicates are included here, with links to Leap2A documentation. Values of the rel attribute in atom:link elements need to be treated as predicates and are included, but the values of other attributes are not included here, even if they might be represented in RDF with their own leap2: predicates (see Leap2R).

The Leap2A/elements page may also be helpful, listing Atom elements.

Table of Leap2A predicates

See the table at http://terms.leapspecs.org/ which includes all of these properties/ predicates together with item types. This table may be removed in the future as it is redundant.
