Introduction
HCM Atom feeds provide notifications of Oracle Fusion Human Capital Management (HCM) events and are tightly integrated with REST services. When an event occurs in Oracle Fusion HCM, the corresponding Atom feed is delivered automatically to the Atom server. The feed contains details of the REST resource on which the event occurred. Subscribers who consume these Atom feeds use the REST resources to retrieve additional information about the resource.
For more information on Atom, please refer to this.
This post focuses on consuming and processing HCM Atom feeds using Oracle Service Oriented Architecture (SOA) Cloud Service. Oracle SOA Cloud Service provides a PaaS computing platform solution for running Oracle SOA Suite, Oracle Service Bus, and Oracle API Manager in the cloud. For more information on SOA Cloud Service, please refer this.
Oracle SOA is the industry’s most complete and unified application integration and SOA solution. It transforms complex application integration into agile and re-usable service-based connectivity to speed time to market, respond faster to business requirements, and lower costs.. SOA facilitates the development of enterprise applications as modular business web services that can be easily integrated and reused, creating a truly flexible, adaptable IT infrastructure.

Main Article
Atom feeds enable you to keep track of any changes made to feed-enabled resources in Oracle HCM Cloud. For any updates that may be of interest for downstream applications, such as new hire, terminations, employee transfers and promotions, Oracle HCM Cloud publishes Atom feeds. Your application will be able to read these feeds and take appropriate action.
Atom Publishing Protocol (AtomPub) allows software applications to subscribe to changes that occur on REST resources through published feeds. Updates are published when changes occur to feed-enabled resources in Oracle HCM Cloud. These are the following primary Atom feeds:
Employee Feeds
New hire
Termination
Employee update
Assignment creation, update, and end date
Work Structures Feeds (Creation, update, and end date)
Organizations
Jobs
Positions
Grades
Locations
The above feeds can be consumed programmatically. In this post, Node.js is implemented as one of the solutions consuming “Employee New Hire” feeds, but design and development is similar for all the supported objects in HCM. Read the complete article here.

My article on Oracle Process Cloud Service has just been published by OTech Magazine in its Fall 2015 "OpenWorld Special" edition. Oracle has been releasing a number of different cloud products, including Oracle Process Cloud Service (PCS) as an addition to its on-premise Oracle BPM Suite offering. This article briefly explains what PCS is about.
