README

Cogs is a suite of interfaces for common objects, primarily used in business and ecommerce (but not limited to that scope).

Cogs is a work in progress. The interfaces are not complete or stable. There are more interfaces yet to be defined. The interfaces have been heavily influenced by OASIS recommendations.

The intent is to achieve some level of interoperability between applications by having them conform to these interfaces.

Suggestions, comments, and contributions are welcome.

Installation

Via composer:

composer require abivia/cogs

Enums

InvoiceTransactionType

This defines the types of transactions that can be applied to an invoice (debit, credit, or non balance affecting)

PartyType

This identifies the two basic types of Party: individuals and organizations.

Interfaces

Most interfaces are designed to represent objects that are stored in a data set and are retrievable by a unique identifier.

AddressInterface

An AddressInterface represents an address that's stored in a data set. The interface is adapted from commerceguys/addressing which in turn is adapted from open standards. Cogs uses an international nomenclature for addresses, so there are accessors for locality() rather than city().

AddressProperties

The AddressProperties interface defines accessors for objects that contain address-like information, for example a geocoded location.

ChannelInterface

A ChannelInterface defines a Communications Channel, a way to contact a party independent of medium. A channel can define a connection by phone, email, chat, etc.

HistoryInterface

A HistoryInterface represents an interaction with an object. This is intentionally abstract. A history record could document up/down transitions in a service or log a history of conversations with a Party.

InvoiceInterface

This interface provides a standard definition for an invoice, including the related parties, amounts, tax rules, and status.

InvoiceTransactionInterface

This interface represents anything that affects the balance or payment parameters of an invoice.

PartyInterface

The Party interface represents a person or organizational entity (corporation, government, school, etc.).

PartyRelationshipInterface

The Party relationship interface defines a link between two parties. The interface is used to represent commercial relations (vendor, supplier), person to person relations (manager, employee), etc.

TaxItemInterface

The Tax Item interface represents the application of a Tax Rate. The rate may be applied to an invoice, to individual items in an invoice, or at any point where a specific tax amount is payable.

TaxRateInterface

A Tax Rate is an amount of tax that will be applied to a transaction.
