NOTE 1- The prescribed manner may be a partially ordered sequence of steps.
NOTE 2 – The activity structure concepts provided in clause 13.1 of Rec.ITU-T X.902 | ISOIEC 10746-2 may be used, aftersubstitution of ‘step’ for ‘action’ and ‘process’ for ‘activity’ , to specify the structure of a process.
NOTE3- A process may have multiple end points.
NOTE4- An cnterprise specification may define types of process and may define process templatcs.
NOTE 5- A process is an abstraction of a behaviour, and so shares any objectives defined for that behaviour.NOTE 6- A process specification can be a workflow specification.
6.3.7step:An abstraction of an action, used in a process, that may leave unspecified some or all of the objects thatparticipate in that action.
6.3.8violation: A behaviour contrary to that required by a rule.
NOTE- A rule or policy may provide behaviour which is to occur upon violation of that, or some other, rule or policy.
6.4Deontic concepts
6.4.1 deontic token: An enterprise object which expresses a constraint on the ability of an active enterprise objectholding it to perform certain actions. An active enterprise object carries a set of deontic tokens，which control theoccurrence of conditional actions within its behaviour. These tokens are either permits, burdens or embargos. A deontictoken is not itself an active enterprise object; it is held by exactly one active enterprise object.
NOTE – The constraint is expressed by a rule forming part of the token; an appropriate notation for expressing this rule will beselected by the specifier.The notation allows the declaration of the active enterprise object and conditional action to which itapplies, and requirements on other cnterprise objects fulfilling roles in the conditional action controlled.For example, the rule maycontrol the performance of a purchase action by a consumer, and place restrictions on the supplier and the artefact being purchased.The notation may also declare periods of validity or deadlines for performance of the action. The kind of associated informationallowed will depend on whether the token is a permit, a burden or an embargo.
6.4.2token group: A group of tokens named so that it can be referred to as a whole.
NOTE-Anotation for expressing deontic rules will provide the means for declaring and naming groups of deontic tokens.Changesthat result, for example, from the performance of speech acts can then be applied to complete groups of tokens without the need toreference all the group members individually.
6.4.3burden: A deontic token encapsulating the statement of an obligation on the active enterprise object holding it.thereby modifying the urgency of the active enterprise object in performing associated conditional actions within itsbehaviour.
6.4.4embargo: A deontic token encapsulating the statement of a prohibition on the active enterprise object holdingit, thereby modifying the ability of the active enterprise object to perform associated conditional actions within itsbehaviour.
6.4.5permit: A deontic token encapsulating the statement of a permission on the active enterprise object holding it.thereby modifying the ability of the active enterprise object to perform associated conditional actions within its behaviour.6.4.6 conditional action: An action which has associated preconditions based on the sets of burdens, permits andembargos carried by the active enterprise objects filling its various action roles.The specification of the conditional actionstates what permits are required for, what burdens favour, and what embargos inhibit performance of the action.
6.4.7speech act: An action whose performance results in a change to the sets of deontic tokens (permits,embargosand burdens) carried by the active enterprise objects filling its various action roles. A speech act may result in the additionof new tokens to the performer of an action role, or in the removal of tokens from the performer of an action role, or thetransfer of tokens from the performer of one action role to the performer of another action role in the same interaction.
NOTE 1 -Many actions for which parties are accountable are speech acts; examples are prescription and commitment.
NOTE2 – Although we speak informally of a speech act as changing or transferring a token, it is more precise to describe thisprocess as the dcstruction of one of the token existing before the act occurred and the construction of a new token based on theinformation available when the act is performed. The definition of the speech act type includes the formal rules governing thecontent and location of the token that is generated.Transfer of a token by a speech act is therefore the process of destruction of atoken held by one of the participating objects followed by construction of a new token with the same contents at its destination.BS ISO IEC 15414 pdf download.
