Trading Partner Information

Collaboration Protocol Profile (CPP) A document which allows a Trading Partners to express their

supported Business Processes and Business Service Interface requirements in a manner where they can be universally understood by other ebXML compliant Trading Partners.

Collaboration Protocol Agreement (CPA) A document that represents the intersection of two CPP’s and

is mutually agreed upon by both Trading Partners who wish to conduct eBusiness using ebXML.

✦ The Messaging Service✦ The Business Process requirements that are agreed upon by two or

more Trading Partners


Business Process and Information Modeling [1]

Business Process and Information Meta ModelA mechanism that allows Trading Partners to

capture the details for a specific business scenario using a consistent modeling methodology.

Core Components and Core Library Functionality [1]

Core Component Captures information about a real world business concept,

and the relationships between that concept, other Business Information Objects, and a contextual description that describes how a Core or Aggregate Information Entity may be used in a particular ebXML eBusiness scenario.

Storable and retrievable using an ebXML Registry Mechanism.

Capture and hold a minimal set of information to satisfy eBusiness needs.

Capable of being expressed in XML syntax.


Capable of containing Another Core Component in combination with one or

more individual pieces of Business Information Objects.

Other Core components in combination with zero or more individual pieces of Business Information Objects.

Be uniquely identified.

Registry Functionality [1]

Registry Provides a set of services that enable that sharing of information between

Trading Partners. A component that maintains an interface to metadata for a registered

item.

Accommodate the storage of items expressed in syntax using multibyte character sets.

Each Registry item, at each level of granularity as defined by the Submitting Organization, MUST be uniquely identifiable.

Return either zero or one positive matches in response to a contextual query for a unique identifier.

The Registry Interface serves as an application-to-registry access mechanism.



The Registry Interface SHALL be designed to be independent of the underlying network protocol stack(e.g. HTTP/SMTP over TCP/IP).

Registry Services exist to create, modify, and delete Registry Items and their metadata.

Unique Identifiers (UIDs) SHALL be assigned to all items within an ebXML Registry System.

Components in ebXML MUST facilitate multilingual support.

Messaging Service Functionality [3] Provides a secure, consistent and reliable mechanism to

exchange ebXML Messages between users of the ebXML infrastructure over various transport Protocols (possible examples include SMTP, HTTP/S, FTP, etc).

Prescribes formats for all Messages between distributed ebXML Components including Registry mechanisms and compliant user Applications.

Does not place any restrictions on the content of the payload.

Supports simplex (one-way) and request/response (either synchronous or asynchronous) Message exchanges.

Supports sequencing of payloads in instances where multiple payloads or multiple Messages are exchanged between Trading Partners governed by CPA.
