Communication Parameters may address characteristics such as communication endpoints, addressing, protocol selection, Topic identification, message characteristics, connection behavior, or other properties relevant to information exchange. text/html 2026-08-20T22:21:41+00:00 nick_dido (nick_dido@undisclosed.example.com) https://wiki.didosolutions.com/dido/99_annexes/annex-b-terms-and-definitions/s/synchronization_parameter?rev=1787264501&do=diff Synchronization Parameter Go up to Terms and Definitions Discussion A Synchronization Parameter specifies a characteristic used to govern synchronization among representations, states, events, or activities.

Within a Twin Relationship, Fidelity Criteria establish the conditions used to assess whether a Twin Realization represents an applicable characteristic with sufficient correspondence for the intended purpose. text/html 2026-08-20T21:53:36+00:00 nick_dido (nick_dido@undisclosed.example.com) https://wiki.didosolutions.com/dido/99_annexes/annex-b-terms-and-definitions/s/source_selection?rev=1787262816&do=diff Source Selection Go up to Terms and Definitions Discussion Source Selection determines which Data Source supplies data for a defined purpose when more than one eligible Data Source is available. Source Selection operates on Data Sources whose eligibility has already been established. Eligibility therefore identifies the permitted set of Data Sources, while Source Selection determines which member of that set supplies the applicable data. text/html 2026-08-20T21:52:57+00:00 nick_dido (nick_dido@undisclosed.example.com) https://wiki.didosolutions.com/dido/99_annexes/annex-b-terms-and-definitions/d/data_source?rev=1787262777&do=diff Data Source Go up to Terms and Definitions Discussion A Data Source identifies an origin from which data is obtained. A Data Source may be a Node, system, service, datastore, sensor, process, simulation, recorded dataset, publisher, or other identifiable origin of data. The concept identifies the origin of the data independently of the communication mechanism used to obtain the data.

Participating Twin Realizations may use different names, data structures, types, units, encodings, Topics, fields, or communication mechanisms for the same represented characteristic. text/html 2026-08-20T19:32:00+00:00 nick_dido (nick_dido@undisclosed.example.com) https://wiki.didosolutions.com/dido/99_annexes/annex-b-terms-and-definitions/t/twin_relationship?rev=1787254320&do=diff Twin Relationship Go up to Terms and Definitions Discussion A Twin Relationship establishes the semantic relationship between a Twin Identity and the Twin Realizations associated with that identity.

A Twin Node maintains a controlled relationship with a corresponding Node so that selected aspects of the Node's identity, Configuration, state, behavior, communication, or lifecycle are observed, represented, simulated, synchronized, or compared.
