Get providers for a flow

This method returns the processes that produce a given product (as output) or provide the treatment of a given waste flow (as input). Thus, the flow parameter of this method needs to be a product or waste flow (or an ID of that flow). The returned providers can be linked to respective product inputs or waste outputs of other processes in a product system.

Examples

Python IPC

import olca_ipc as ipc
import olca_schema as o

client = ipc.Client()
providers = client.get_providers(
    flow=o.Ref(id="7f6bb533-2d3c-43a6-ac60-6eef299d7c52")
)
for p in providers:
    print(p)
# TechFlow(
#   provider=Ref(id='71dab7ae-4d58-4f73-8449-5967c296bcde', ...
#   flow=Ref(id='7f6bb533-2d3c-43a6-ac60-6eef299d7c52', ...

JSON-RPC via Fetch API

The example below shows the usage of this method using the JSON-RPC protocol via the Fetch API which is available in modern web-browsers or platforms like Deno.

  let resp = await fetch("http://localhost:8080", {
    method: "POST",
    body: JSON.stringify({
      jsonrpc: "2.0",
      id: 1,
      method: "data/get/providers",
      params: {
        // only the ID is required here
        "@type": "Flow",
        "@id": "66c93e71-f32b-4591-901c-55395db5c132",
        name: "electricity, high voltage"
      }
    })
  });
  let v = await resp.json();
  console.log(v);
  // {
  //   jsonrpc: "2.0",
  //   result: [
  //     {
  //       provider: {
  //         "@type": "Process",
  //         "@id": "ba98a130-d92c-4c40-8fe9-c8cab5b956ab",
  //         name: "electricity production, wind, 1-3MW turbine, onshore",
  //         processType: "LCI_RESULT",
  //         flowType: "PRODUCT_FLOW"
  //       },
