Creating Collection

A collection may be created with or without explicitly defining schema definition for the records. However, it is always recommended to define a schema for the collections of records.

Simple Collection

A Simple Collection can be created in the data section of the Internet object document by prefixing each record with a tidal sign (~ U+007E). It enables the parser to identify the next record when multiple records are sent.

In the Simple Collection as the schema is not defined the type and the structure of collection records can differ.

# Creating a simple Collection
---
~ Ironman, 20, Male, {Bond Street, New York, NY}
~ Spiderman, 25, Male, {Duke Street, New York, NY}, cool

Explicit Collection

An Explicit Collection is created by explicitly defining the schema for the collection of records. Prefixing schema with the tidal sign (~ U+007E) enables the parser to understand the multiple records that may be sent according to a particular schema definition.

# Creating an Explicit Collection
~ $address: {street, city, state}
~ $schema: { 
            name: string, 
            age: {int, min:28}, 
            gender: {string, choices: [Male, Female]}, 
            $address
            }
---
~ Ironman, 20, Male, {Bond Street, New York, NY}
~ Spiderman, 25, Male, {Duke Street, New York, NY}
~ Wonderwoman, 25, Female, {Z street, San Francisco, California}

Here in the code snippet, multiple records are passed in the data section of the document using Collections.
