Service Architecture

The service is constructed from two key components, Listing Registry and Listing Resolver.

Listing Registry

1. A simple registry of listings where each listing comprises of:

• An ID

• An Owner

• A Resolver

Owners will own the listings they create and have permission to create, update and delete them.

Listing Resolver

A resolver is any API or web based service that has implemented a specific and standardized interface to return listing content based on a set of open source schemas.

Implementing an open standard resolver interface allows Plano or anyone else to create and manage a distinct dataset of listing data, while at the same time providing a common interface for the consumption and use of them by end users and user focused websites.
