PLCS Standard OWL

Introduction

This document describes version 1.0 of the PLCS Standard OWL namespace. It also contains a directory of links to related resources.

Namespace URI Versioning Policy

It is the intent of the OASIS PLCS Technical Committee that the PLCS Standard OWL namespace URI will not change arbitrarily with each subsequent revision of the corresponding WSDL or XML Schema documents but rather change only when a subsequent revision, published in conjunction with a Committee Draft, results in non-backwardly compatible changes from a previously published Committee Draft.

Under this policy, the following are examples of backwards compatible changes that would not result in assignment of a new namespace URI:

• addition of new global element, attribute, complexType and simpleType definitions
• addition of new operations within a WSDL portType or binding (along with the corresponding schema, message and part definitions)
• addition of new elements or attributes in locations covered by a previously specified wildcard
• modifications to the pattern facet of a type definition for which the value-space of the previous definition remains valid or for which the value-space of the preponderance of instance would remain valid
• modifications to the cardinality of elements for which the value-space of possible instance documents conformant to the previous revision of the schema would still be valid with regards to the revised cardinality rule
