S3XRC | S3 RESTful API | S3Resource

S3Resource Class

Introduction

Resources are dynamic, document-alike representations of data objects on the Eden server. As such, they can represent both single instances as well as structured sets of data objects.

Note: in the database context, a single instance of a data object is typically called a record (or row), with fields (or columns) as its atomic elements. However, even though S3Resources are typically bound to a relational database and therefore the record/field terminology is often used in this regard, they are not intended to provide any object-relational mapping (ORM).

S3Resources implement an extensible, multi-format ​RESTful API to retrieve and manipulate data on the Eden server by ​HTTP requests, where every resource can be addressed by an individual ​URL.

In the context of the Model-View-Controller (MVC) architecture, S3Resources are controller-generated objects. Typically, the controller generates a resource in response to an incoming HTTP request and returns a view of it (output) to the client:

Terminology

A S3Resource consists of elements which can be either resources themselves (container type) or data (atomic types).

Container type elements within a resource can be:

• primary resources (independent data objects)
• component resources (objects which are part of a primary object)
• referenced resources (objects which are referenced by primary or component resources)
