[occi-wg] OCCI XML description

[Jean Parpaillon]

Hi,
Following the OCCI-WG session in Madrid and my presentation at the
workshop, please find here the link to the work I've done on XML
representation of OCCI.

The presentation:
http://fr.slideshare.net/JeanParpaillon/occi-xml-description

The schemas and examples: https://github.com/jeanparpaillon/occi-schemas


The objective is to be able to describe in a formal way the OCCI
extensions, independantly from implementation languages (Python, Ruby,
Java, etc).
Basic architecture:
- XSD describe OCCI types XML representation
- OCCI extensions are described with XML files, validated with XSD.
- OCCI representation can be validated with above XML file, which is not
an XSD. Nervertheless, XML extension file is formal enough for
implementation to validate rendering.
For attribute types (string, numbers, etc.), we use the XML schema type
model to describe them. For instance, a mac address is described with:

<xs:simpleType name="mac802">
  <xs:restriction base="xs:string">
    <xs:pattern value="[\da-fA-F]{2}(\:[\da-fA-F]{2}){5}" />
  </xs:restriction>
</xs:simpleType>
