This page provides information on how to create Catalogs.

**DocDigitizer WorldObjects** lets you choose what information you want to work with, then the system retrieves the data from the appropriate systems without you knowing what the source systems are.

_A Catalog is the "data domain" of a particular object, where you can add or associate a list of values such as "list of countries."_

As mentioned, DocDigitizer WorldObjects offers varying ways to define Catalogs, one of which is called "Local Catalogs."

## Rules for Local Catalogs

The "Local Catalog" Catalog is structured like a CSV, where:

• The first row is the Header, which must have as many columns as the number of object properties and their names

• Column separator character can be either:

  • | (pipe)

  • , (comma)

• The escape character is "" (double quote)

The same rules that you use when creating CSV apply here.

## Local Catalogs—"in code"

The first step is to identify an Object that has reference data, like "Countries", "Gender", or "Zip Codes."

To demonstrate the creation of a Catalog we will use the object "Gender" created in the previous step (Gender).

## Requirements of a Catalog

Let’s assume that we needed to have a “Gender” entity, which will have the list of values of the different types of Gender:

• M - Male

• F - Female

• X - Other

## Create Catalog Values

Open your VS Code and go to your workspace. Select object "Gender." Add the following data structure:

In the Developer Guide and Tutorials, you will find more information about Catalogs and how to use them. The next step is how to create the build.
