OCCI-OS interface started by Thijs Metsch from Intel andAndy Edmonds with community contributions.Code locations:
Stackforge will become the official place (being migrated):https://github.com/stackforge/occi-osThjis repository (development):https://github.com/tmetsch/occi-osMy repo (development with additions):https://github.com/alvarolopez/occi-os/
stable/<release_name branches should contain stable codeto be deployed with the corresponding version.Usage documentationhttps://wiki.openstack.org/wiki/Occi

OCCI-OS Configuration
Add it to the nova’s api-paste.ini configuration:
[composite:occiapi]use = egg:Paste#urlmap/: occiapppipe
[pipeline:occiapppipe]pipeline = authtoken keystonecontext occiapp# with request body size limiting and rate limiting# pipeline = sizelimit authtoken keystonecontext ratelimit occiapp
[app:occiapp]use = egg:openstackocci-grizzly#occi_app
Enable it in your nova.conf file:
enabled_apis=ec2,occiapi,osapi_compute,osapi_volume,metadata
Restart nova-api and you’re done.

Use it!
First get a keystone token first:
$ curl --insecure -H \"Content-type: application/json" -d ’{"auth": \{"tenantName": "whatever", "passwordCredentials": \{"username": "demo", "password": "secret"}}}’ \https://keystone.example.org:5000/v2.0/tokens
(...)"token": {
"expires": "2013-09-20T14:34:54Z","id": "ae6259e89fc8434a8d7122e1f9fdc0f0","issued_at": "2013-09-19T14:34:54.827264",(...)
Grab the token ID:
export KID=ae6259e89fc8434a8d7122e1f9fdc0f0

Use it!
See what you can provision:
$ curl -v -H ’Content-Type: text/occi’ \-H ’X-Auth-Token: ’$KID \-X GET http://cloudapi.example.org:8787/-/

Use it!
Spawn a virtual machine:
$ curl -v -X POST http://cloudapi.example.org:8787/compute/ \-H ’Category: compute; scheme="http://schemas.ogf.org/occi/infrastructure#"; class="kind"’ \-H ’Content-Type: text/occi’ \-H ’X-Auth-Token: ’$KID \-H ’Category: m1-tiny; scheme="http://schemas.openstack.org/template/resource#"; class="mixin"’ \-H ’Category: 18d99a06-c3e5-4157-a0e3-37ec34bdfc24; scheme="http://schemas.openstack.org/template/os#"; class="mixin"’ \-H ’Category: public_key; scheme="http://schemas.openstack.org/instance/credentials#"; class="mixin"’
