 +
 +===== Discussion =====
 +
 +A Data Source identifies an origin from which data is obtained.
 +
 +A Data Source may be a [[public:99_annexes:annex-b-terms-and-definitions:n:node|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. For example, a [[public:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] DataWriter may provide access to data originating from a Data Source without becoming the semantic definition of that Data Source.
 +
 +A Data Source may be subject to eligibility, authority, provenance, security, or other constraints established by the applicable architecture or [[public:99_annexes:annex-b-terms-and-definitions:c:configuration|Configuration]].

 +===== Source =====
 +
 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-001|[DTE1] U.S. Patent Application US20220237111A1]], virtual and physical Twin Node concepts and data used during testing and comparison
 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-002|[DTE2] Non-Traditional BAA Submission]], Digital Twin concepts and Twin Nodes Selection
 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-009|[DTE9] Distributed Immutable Data Object Reference Architecture (DIDO-RA)]], DDS publish-subscribe and distributed data concepts
 +  * DIDO-TE normalization of the source concepts
 +
 +===== Note =====
 +
 +Identification of a Data Source does not establish permission to use data from that source.
 +
 +Eligibility, selection, authority, and trust are separate concerns established by the applicable governance, Configuration, or Test Definition.
 +
 +A communication endpoint, network address, DDS DataWriter, Topic, file, or database connection may identify an implementation mechanism associated with a Data Source without defining the Data Source itself.
 +
 +===== Example =====
 +
 +A physical sensor attached to a real-world Node is a Data Source for temperature measurements.
 +
 +A simulation representing the same Node is a different Data Source even when both sources publish compatible temperature data through the same DDS Topic.
