Task #4258
Story #2829: Structural changes to D1 Data Types schema for Version 2.0 release
Add Generic key/value element to Node
100%
Description
(02:05:41 PM) robert: Matt, you want the product name of the MN software stack added into the node object?
(02:07:09 PM) matt: and version
(02:07:15 PM) matt: I think we need more node metadata in there
(02:07:23 PM) vieglais: good point.
(02:07:59 PM) matt: Dave and I had talked about adding a name/value pair field to the schema that would allow a variety of node properties to be added
(02:08:12 PM) robert: ok. I'll add it in to my list of v2 changes
(02:08:23 PM) matt: dave -- we talked about that when we were discussing the need for more node metadata for the dashboard
Something like some unformatted software stack version
The main problem is the uncontrolled nature of the key and value. If the key will result in machine actionable workflow, then we should have some list of controlled vocabulary/format that the tokens are validated against.
Maybe the property should have a type to indicate whether or not it is a controlled name and therefore machine actionable.

I agree a controlled vocabulary would be great. An effective way to do this would be to type the key attribute as an xs:QName so that the values in the attribute can be typed and therefore validated by the XML parser. For example, the following snippet would use this technique:
Metacat
2.5.0
And the 'property' element would be based on a schema containing this ComplexType definition:
xs:complexContent
/xs:restriction
/xs:complexContent
/xs:complexType
Not sure if this would allow enough extensibility on the fly, as it might be just as restrictive as adding new elements to the node schema, unless we can find a way to modify the DataONENodeProperties schema without revising everything else. Might or might not work. Just a thought.

Added Property type and Node can have 0..n of them. Includes a key, a type and, of course, the value.
