Resource Agents 1.1: fixing the OCF resource agent metadata schema

*

One Line Summary

An overview of proposed updates to the XML schema we use to define OCF resource agent metadata

Abstract

The OCF RelaxNG schema (previously a DTD) which we are currently shipping with resource-agents 1.0 is lacking a few key components. We have no way to express that a resource agent (or parameter) is obsolete or deprecated. We can not express one resource agent being superseded by another. We have limited resource agent parameter types, with lists and enumerations being notably absent from the schema. This presentation will highlight this and other weaknesses in the current schema, and provide suggestions to eliminate them.
