Web Service Level Agreements (WSLA) Project

WSLA Schemas and Examples

The WSLA schema according to which SLAs are defined in WSLA. This XML schema contains the necessary definitions for the various parties, the SLA parameters and how they are computed, as well as the definitions for the parties' obligations, such as Service Level Objectives (SLOs) and Guarantees.

The WSLA Service Deployment Information (SDI) language is a derivative of the WSLA language. It contains substructures of an SLA that represent the information a particular third party service needs to know about its role in SLA enforcement. The complete WLSA schema is included and "re-packaged" for the particular needs of the supporting party service types.

This is the complete example of an SLA with multiple parties; it is also included in Appendix 3, starting on page 93, of the WSLA Language Specification.
