Graffiti Directory
A common API to "tag" and search across existing and new services for cloud content based on the metadata vocabulary, ad-hoc properties, names, and descriptions.
Expanded Contextual Overlay
This overlay Graffiti concepts with Graffiti components.
Resources
In Graffiti, resources are a common way to represent a type of resource from a given provider. They have the following:
- Name
- Description
- Resource Type
- Resource Endpoint
- Freeform properties (those not associated with a known namespace in the dictionary)
- Flat properties (those associated with a namespace, but not a capability type in the namespace)
- Capabilities (instances of capability types)
- Requirements (references to required capability types as well as the constraints)
For example, a resource may be of type volume. It may come from a specific Cinder endpoint registered in Keystone. It may have the capability of a certain kind of OS and may also have MySQL on it.
