Indicates that a DataReuseLicense requires some kind of authorization step, from SelfAuthorization (click-through) to processes that require a data steward to grant permission.
An annotation that assigns lexical elements of language to classes on the basis of their distributional properties (for sign languages, the term 'sign class' is appropriate).
An annotation that includes information about the sound system of a language, such as the contrasts between sounds which make up the sound system and the locally conditioned realisations of sounds which characterise speech in the language.

A set of DefinedTerms for access authorization mechanisms - some of these may be combined, e.g. AccessControlList and AgreeToTerms, but SelfAuthorization and AgreeToTerms would be redundant.
A user is expected to explicitly agree to a set of license terms, this may be combined with AccessControlList - to note that even if a user has been pre-approved for a license they must agree to license terms.
Users may apply for a license via some workflow, such as a form, with the decision being made by a DataSteward or their delegate about whether to grant the license.
A user can be authorised to access data by clicking that they agree to a license, or filling out a form to check their understanding, which can be validated by a machine and does not require human intervention.
An interactive discourse with two or more participants. Examples of dialogues include conversations, interviews, correspondence, consultations, greetings and leave-takings.
