This schema describes the UK federation label namespace. For additional information, see the Federation Technical Specification. This version of the schema includes the UKFederationMember and AccountableUsers elements described in FTS edition 1.5 of 6-October-2014. All other types and elements defined here are for UK federation internal use only and are not for publication. Most elements defined in the UK federation label namespace are basic labels: empty elements whose presence or absence is all that is important. A datedLabel is like a basicLabel, but with a single additional mandatory date attribute. An organization ID is a string constrained to be the string "ukforg" followed by a numeric code. These codes are defined as IDs in the members.xml database, but are simple strings in entity metadata. Indicates an entity whose owner is a member in good standing of the UK federation. orgID is a mandatory attribute as we stopped publishing UKFederationMember labels. It is also mandatory in entity fragment files. Indicates an identity provider entity whose owner has asserted to the UK federation that the entity provides user accountability in terms of the definition given in section 6 of the federation's Rules of Membership. Indicates the software used to implement the entity, and optionally both general and specific indications of the version of software used. This information is added to an entity only if it has been received from the deployer of the entity on the indicated date. This information is used in entity fragment files only, and is not included in the metadata published by the UK federation. Its principal use is in classifying entities for statistical purposes. The name of the software used to implement the entity. Although not described as such in this schema, the name should be picked from the controlled vocabulary understood by the federation statistics scripts. The general version of the software in use. This should only be specific enough to identify the broad functionality of the entity, for example "1.3" vs. "2.0" would be sufficient for Shibboleth entities. The specific version of the software in use, if known. Indicates that the entity has been opted-in to inclusion in the UK federation export aggregate. Indicates that the entity has been opted-out from inclusion in the UK federation export aggregate. A controlled vocabulary of names of flows in the UK federation tooling. Because we know the valid flow names, we can restrict values of flowName to just those names. A flow constraint is a dated label naming a flow within the UK federation tooling. Indicates that the entity should be removed from the named flow. If labelled with multiple DisableFlow elements, the entity should be removed from each named flow. An entity MUST NOT be labelled with both EnableFlow and DisableFlow elements. Indicates that the entity should be allowed to pass through the named flow, and removed from other flows. If labelled with multiple EnableFlow elements, the entity should be allowed to pass through all named flows, and only removed from flows not named by any EnableFlow element. An entity MUST NOT be labelled with both EnableFlow and DisableFlow elements.
