Metadata service

1. Introduction

The current version of the OpenSocial Specification documents a limited metadata service -- you can ask the OpenSocial server what fields are supported by a particular service. This is partly useful, but a more complete metadata service would enable apps to provide a more compelling user experience, as well as adapt to differences in Jive instances due to configuration choices.

2. Data Models

2.1 Field Metadata

Each FieldMetadata instance represents a field that may be present in a particular entity of the containing object type.

Field NameTypeDescription| array | Boolean | Flag indicating whether this field is an array (true) or scalar (false). |

availability	String	Description of conditions on when this field will be available for a particular object.
description	String	Description of this field.
editable	Boolean	Flag indicating whether this field is modifiable on create and update operations.
name	String	Name of the key under which this field will be present.
required	Boolean	Flag indicating whether this field is required on create and update operations.
since	String	Jive Core API version in which this field is initially available.
type	String	Object type of this field.

2.2 Object Metadata

Each ObjectMetadata instance represents all of the metadata associated with a particular object type.

Field NameTypeDescription| availability | String | Description of conditions on when this object will be available. |

description	String	Description of this object type.
fields	FieldMetadata[]	Description of all possible fields that may appear in this object.
name	String	Formal name of this object type.
resourceLinks	ResourceMetadata[]	Description of all possible resource links that may appear in this object.
since	String	Jive Core API version in which this object is initially available.

2.3 Property Metadata

Each PropertyMetadata instance represents a configuration value for this Jive Instance.

Field NameTypeDescription| description | String | Description of this property value |

name	String	Name of this property value
type	String	Object type of this property value
value	Object	The current value of this property

3. REST APIs

Verb and Request URIResponse BodyDescription| GET /metadata/objects | Map<ObjectTypeName,MetadataURI> | Return a JSON object whose keys are all supported object types in this Jive instance, and whose values are the URI to retrieve the detailed metadata for that object type. |

GET /metadata/objects/ Unknown macro: {objectName}	ObjectMetadata	Return the object metadata for the specified object name.
GET /metadata/properties	PropertyMetadata[]	Return all of the configuration properties for this server instance.

4. JS APIs

These will match the OS standard JS pattern.
