ComponentElement
| A part of a Composite. |
|
|
Composite
| A group of two or more entities combined for any purpose. Examples: an XML Message, a group of elements within a Message such as "TitlesComposite". A Composite does not represent anything in its own right but is only a collection or "bag" of entities which normally have some kind of relationship. Composites may contain other Composites to any level of granularity. |
|
|
Context
| An intersection of Time and Place in which something may happen (an Event) or exist (a State). Example: releasing a Product in France on May 5th 2005 is an Event; a Product being available for sale in France from May 5th 2005 until December 25th 2005 is a State. |
|
|
Place
| A geographical or virtual location. |
|
|
Resource
| Something which plays a role in a Context but is not a Time or a Place: Resource is therefore the "catch-all" parent for other entities. Resources may be physical, digital or abstract concepts, and include the Products, Releases, Recordings, Works and other human-made Creations which are the objects of creative and commercial activity; but Resource also includes the people or organizations (Parties) who can act as agents, and all forms of tools and materials which may be used or referenced in the processes described within PCS. |

Time
| A point or period of linear time. In PCS times (including dates) are expressed in an ISO 8601:2004 compliant format. |
