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 “Tell, Don’t Ask”. As the Party class is large, and important to the System.Identity model,…

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 Do With ‘Oslo’”. While I think Kraig’s post covers a number of…

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 IT (MSIT) software architecture. Writing the paper took quite a bit more…

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() method inherited from System.Object. In accordance with MSDN guidance, I’ll be writing an overload of the GetHashCode()…

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

As I wrote in Part 2 of the series, System.Identity ships in the latest Oslo CTP as part of the Oslo Repository. This has the direct effect of introducing ORM database persistence considerations into the design of the System.Identity fluent interface I’ve been crafting. One of these considerations has already manifested in the following snippet…

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 code. In this post I’ll continue the crafting of the fluent interface by exploring…

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 going to start putting his suggestion into practice by chunking further posts…

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 rich Object-Oriented runtimes to consume Oslo metamodels. At the end of the post…

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 dive into M – particularly modeling types using M (formerly known as…

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 in M types (formerly MSchema) and creating a SQL Server DB for…
