Fluent Interface for System.Identity – Party Implementation (Part 1)

This latest post on developing a fluent interface for the Oslo System.Identity schema will start an implementation of the Party class. Per the architectural specifications for the fluent interface, the Party class will adhere to the Law of Demeter and

A Real World Use For Oslo

I’m going to take a small detour from my series on a fluent interface for Oslo’s System.Identity schema to propose a real world scenario where Oslo could be leveraged. This post has its genesis in Kraig Brockschmidt's recent post “ What Exactly Does One

Fluent Interface for System.Identity – Kind’s Expression Builder

<Author’s Note> It’s been quite a while since my last blog post. The reason for the gap was due to my non-work time being consumed with swimming (some might say wallowing ;-) in the architectural soup writing a ThinkWeek paper related to Microsoft

Fluent Interface for System.Identity – M, Persistence, & GetHashCode()

As I wrote about last time , leveraging the System.Identity schema with the Oslo Repository introduces some ORM database persistence considerations into the design of the fluent interface . In the last article I introduced how to override the Equals()

Fluent Interface for System.Identity – M, Persistence, & Equals()

Fluent Interface for System.Identity – Kind Command-Query API

Part 1 of this series functioned as an introduction to the motivations for creating a fluent interface for Oslo’s System.Identity . Part 1 also covered a number of architectural and design specifications that will be followed in the shaping of the interface’s

Fluent Interface for System.Identity – The Basics

<Author’s Note> A very talented Developer I know just recently gave me some very succinct feedback on my blog - “good blog…too long”. As I respect this Developer’s opinion quite highly (not to mention I always try to listen to Developers ), I am

Oslo “M” Graphs and Inheritance

In my last post I explored the subject of applying Object-Relational Mapping (ORM) concept to modeling in M . What I discovered was that M handles ORM pretty well and allows for the modeling of polymorphic inheritance within M metamodels – thereby enabling

Modeling Inheritance in Oslo’s “M”

As I recently posted , I’m very intrigued by the potential of the Oslo platform to democratize the use of metamodel-driven software architectures. As a first step in exploring the capabilities of the latest Oslo CTP I took some time over the weekend to

Oslo Really is About Model-Driven Development

As I’ve wrote about previously , I’ve flipped the bit on Oslo and I’m currently very excited about the long term prospects for the technology. Like many have wrote about in the blogosphere, I was initially skeptical about Oslo. Seeing the demos for modeling

Implementing UML Associations and Oslo’s System.Identity

As I really don’t have much of a life I was reading an academic paper this evening by Anneke Kleppe . In the References section of the paper there were the a couple of links to some articles on properly implementing UML Associations in source code. The

Exploring the Party Model with Oslo’s System.Identity – Part 3

In Part 1 of this series we covered the basics of how Oslo’s System.Identity implements the Party Model and how System.Identity can be used to model real world scenarios. We continued our exploration of System.Identity in Part 2 by modeling more complex

In Part 1 of this series we discussed the basics of the Party Model using Oslo’s System.Identity schema. Specifically, we discussed the System.Identity constructs for Party, Role (including the Employee and Customer specializations of Role), and TaxonomyEntry

Exploring the Party Model with Oslo’s System.Identity – Part 1

It occurred to me the other day that I asserted that the Party Model is a “Good Thing” without providing any proof whatsoever to back up my claim. While I would love to believe that everyone subscribes to my views and opinions because of their irrefutable
