Data Authoring and Ownership Concepts

A policy:

• may govern one or many types of PLM data
• defines a lifecycle process and associated events
• grants access rights with or without filters to assigned P&O users.

A rule:

• may govern one or more relationships and attributes
• grants access rights with or without filters to specific P&O users.

PLM data:

• is governed by only one policy
• possesses an ownership vector (userid, orgid, projectid) at creation time based on the selected login context
• may be transferred across users or organizations and/or projects.

Data authoring and ownership are at the heart of security. It is important to understand how ownership of PLM objects is defined before progressing to a description of policies and rules.

The security context selected at logon sets the ownership for new data created. For example, user John Doe logs on using a specific security context and is authorized to create a product root:

The product P5 when created is tagged with three ownership attributes:

• Userid
• Orgid
• Projectid.

This means that a variety of VPLM operations on data will only be authorized if the access rights corresponding to those operations are granted to the user.
