Entity Resource Manager Component

[grkvlt]

Manages resources for all Brooklyn entities.

Each entity can obtain a reference to the manager from the global management context. The managed resources can be global or restricted to a single entity or type of entity. They will consist of a set of static source URIs with mappings to paths and filenames on remote entity instances and dynamic URIs that will be resolved at runtime by substituting configuration key and attribute values through placeholders in the source and destination URI strings.

• PAX-URL will be used to resolve source URIs
• Filtering will be performed by FreeMarker or other suitable plugins
• Mapping of names via entity provided transformer functions
• Cacheing of contents at the management plance, before transfer
• Remote resolution and transfer of static resources where possible
• Cloud aware, using jclouds BlobStore
