**[1] `gen_ai.data_source.id`:** Data sources are used by AI agents and RAG applications to store grounding data. A data source may be an external database, object store, document collection, website, or any other storage system used by the GenAI agent or application. The `gen_ai.data_source.id` SHOULD match the identifier used by the GenAI system rather than a name specific to the external storage, such as a database or object store. Semantic conventions referencing `gen_ai.data_source.id` MAY also leverage additional attributes, such as `db.*`, to further identify and describe the data source.

is this common for workflows to have system instructions along with input messages?

Workflow will not have its own but it could be combined from agents->llm's system messages.

I have the same concern. Does a workflow ever actually invoke a model or is it **staticly defined ** control flow?
