Create a new Version

One of the powerful things about lightblue is the ability to deploy multiple versions of an entity at the same time without changing any code. In this section we will create a new version of the country entity that includes a new optional field continentName.

Edit Metadata

Open /tmp/country.json in your favorite editor and add a field after iso3Code so it looks like this:

            "iso3Code": {
                "type": "string",
                "constraints": {
                    "required": true
            "continentName": {
                "type": "string"

Update Metadata

In this section you will create version 1.1.0 of the country entity.

Before lightblue 1.2.0

If you're using a version of lightblue older than 1.2 then you have to follow these steps:

  1. Copy /tmp/country.json to /tmp/country-schema.json
  2. Edit /tmp/country-schema.json
  3. Make the value of the schema element the top level document
    1. remove entityInfo
    2. remove top level currely braces
    3. remove text "schema":
  4. Update version from 1.0.0 to 1.1.0
  5. Save the file

Create a new schema with curl:

curl -H Content-Type:application/json -X PUT ${BASE_URL}/rest/metadata/country/schema=1.1.0 -d @/tmp/country-schema.json

lightblue 1.2.0+

NOTE: this section relies on a feature released with version 1.2.0.

Update metadata with curl:

curl -H Content-Type:application/json -X PUT ${BASE_URL}/rest/metadata/country/1.1.0 -d @/tmp/country.json
