Get the CDM source description from each server

Returns the full cdm_source table row(s) from each connected server, describing the data source (name, abbreviation, holder, release/version dates, etc.). This is metadata, not patient data, so this reader is not disclosure-gated. Sites may describe genuinely different data sources, so the result is deliberately kept per-server and is not merged.

Usage

ds.omop.cdm.source(symbol = "omop", conns = NULL, execute = TRUE)

Arguments

symbol

Character; the session symbol used when the OMOP connection was initialised (default: "omop").

conns

DSI connection object(s). If NULL (the default), the connections stored in the active session are used.

execute

Logical; if FALSE, returns a dry-run dsomop_result containing only the reproducible R code without contacting the servers.

Value

A dsomop_result with scope = "per_site". Each server's result is its cdm_source data frame (empty if the table is absent). pooled is NULL by design.

Examples

if (FALSE) { # \dontrun{
src <- ds.omop.cdm.source()
src$per_site            # one cdm_source frame per server
} # }
