HealthVault Vocabulary Browser

I wrote a little utility to browse vocabularies that I thought you might be interested in. It uses the HelloWorld app id, so you should just be able to dump it to a directory and run it.

Scheming for Schema

As many of you know, we already provide access to the schema for the healthvault types through the Type Schema Browser and the Raw XML API reference page . If those pages don't do exactly what you want - say, you want to look at all the schemas together

Work on your Vocabulary. The word for today is "CodableValue"

Vocabulary and CodableValue are two of the somewhat interesting types in the HealthVault platform, and I thought I'd spend a little time discussing them. So, here's the problem they're designed to solve. In medicine, there are sometimes long lists. The

Dealing with PersonalImage

PersonalImage is a type that encapsulates the picture that shows up for a person in the health record. My current image is this: (those interested into why that is my current image should post the results of their research in the comments) PersonalImage

HealthVault and openness

Yesterday - while I was taking a day off skiing with my wife and daughter - we announced our plans around openness and interoperabiity for HealthVault. I'm pretty excited about this. I'm especially excited about making the current .NET client library

Uploading a file to HealthVault

I came across a question asking how to upload a file to HealthVault, and decided to write a quick example. Files, like everything else in HealthVault, are stored in XML, and in fact, the File class is really a pretty thin wrapper over the underlying type.

Users, records, and multi-record applications

A topic came up yesterday in the forums, and I thought it was of general interest. HealthVault is different from a lot of information systems - at least the ones I've worked with - in that there is a break between the concept of "user" - the person who

Family Health Guy

Sean Nolan, my second-level (aka my manager's manager) and chief HealthVault architect, has started a blog named FamilyHealthGuy (no relation, AFAIK, to Family Guy ), where his initial post, after dealing with matters mursine, talks a bit about why he's

HealthVault: Batching up queries

When I first started using the HealthVault SDK, I wrote some code like this, based on what I had seen before: HealthRecordSearcher searcher = PersonInfo.SelectedRecord.CreateSearcher(); HealthRecordFilter filter = new HealthRecordFilter (Height.TypeID);

The life and times of a HealthVault piece of data...

HealthVault has two temporarl views of data. The first temporal view is fairly obvious. If, for example, you're looking at the Height type, there is a When property that can tell the time at which the height was measured. That allows you to do fun things,

Storing CCR and CCD data in HealthVault

There have been a couple of questions recently about storing CCR and CCD data in HealthVault, so I decided to do a quick sample. The sample will show up in the SDK sometime in the future, so consider this the accompanying discussion for the sample. If

Extending HealthVault data types using a custom extension class

This post will cover the second method of extending a HealthVault data type. If you haven't read about the first method , please do so now. We'll wait. In the first method, we had to deal with all the XML details ourselves, which made it a bit clumsy.

Extending HealthVault data types using HealthRecordItemExtension

So, let's say that you're building an application using the HealthVault Height type, and you find that you need to store another bit of information with that type. What should you do? Well, first, you should probably stop by HealthVault Forum and say,

What data type should I use?

In my previous posts, I kindof glossed over the different kinds of data types you might have in your application and when you might choose a specific type. I now seek to rectify that oversight, but first I need to talk about types in a more general sense:

HealthVault Data Types - a custom data type architecture

In my last post, I showed how to create custom data types, but there's an obvious problem with that approach. There's only one of them. That means that when you do a query for your custom type, you get all the custom types that meet your filter. If your
