I had a talk with ProtectServe folks yesterday and it inspired something about what Contract has to have.

Until the meeting, the basic items that I had in mind were following:

- Subjects
- Signers (If Subject!=Signer, Singer is a proxy and
asserting that he has the agreement with Subject
implicitly.)
- Human Readable Term Text
- Machine Readable Term
- Date
- Period of the Service
- Consideration for the Service (usually in dollar amount.)
- Liability (usually specifying the limit in dollar amount.)
- Corrective Measures
- Termination
- Confidentiality (May persist longer than the duration of the service.)
- Arbitration
- Jurisdiction

During the discussion, an issue with signing software/hardware came up. From the process point of view, it would be importat to know what was used to sign. Thus, probably, the identifier including versions of the software/hardware combination, or more simply put “System” needs to be recoreded somewhere.
