Expression library for condensing Reltio REST API response

[eguo]

Before 2017 Winter Release, transforming a Reltio REST API response JSON object into a simple structure can be a tedious task. The expression library feature from 2017 Winter Release can make it much easier. Encouraged by @dmiller, am sharing a pipeline to showcase this technique. In this fictional scenario, the ask is that only output the Mobile phone fields.

reltio.expr.txt (136 Bytes)
Fake_Reltio API response.json.txt (3.1 KB)
Phone.json.txt (288 Bytes)

How to test the example pipeline:

1. download the pipeline file and reltio.expr.txt
2. rename the reltio.expr.txt to reltio.expr
3. upload the pipeline and reltio.expr to a project
4. generate the previews

Content of the expression library file:

{
    ov: y => y.find(x => x.ov == true).value,
    findByType: (x,type) => x.find(y => this.ov(y.value.Type) == type && y.ov == true)
}

Condensed data from the output:

[
  {
    "uri": "entities/geFfGTn",
    "updatedTime": 1492024546326,
    "attributes": {
      "FirstName": "Gr",
      "LastName": "Moun",
      "Gender": "Male",
      "Phone": {
        "CountryCode": "+1",
        "Number": "9999990003",
        "Type": "Mobile"
      }
    }
  }
]

The input Reltio API response JSON looked like this:
