| 3 | Suffers from a number of [http://www.prescod.net/rest/mistakes/ RESTful no-no's].... |
| 4 | |
| 5 | == Design Questions == |
| 6 | |
| 7 | * What are the resources, and where are they located? |
| 8 | * What data formats are in use? |
| 9 | * What methods are supported at each resource location? |
| 10 | * What status codes could be returned? |
| 11 | |
| 12 | == Current Development Issues == |
| 13 | |
| 14 | * How does a machine client acquire and select from the package license options? |
| 15 | * Can the above POST parameter data types be specified more formally? |
